    The project has focussed on the diseases of Salix in short rotation forestry, with emphasis on the rust fungus, Melampsora ssp., which could be responsible for significant loss in production and dieback of plants. We have studied the virulence patterns of the rust population (rust pathotypes) to be able to give qualified support for analysis of field trials for resistance and advice for choice of breeding strategies. The rust population includes a large number of pathotypes and the variousness indicate a high capacity to adapt to new clones or plantation strategies. The sexual cycle is of crucial importance and gives the rust the property of recombination and exchange of virulence factors every season. The idea with clonal mixtures instead of monoclonal plantations is evaluated on Northern Ireland. The records of pathotypes and genotypes in the rust population in these trials, would after a repeated assessment and analysis give valuable indications concerning the development and selection of rust in relation to plantation design. The question is if a clonal mixture affects the infection pressure or if surrounding plantations and long distance spore migration will eliminate this effect. An analysis of the rust population on european willows in Chile is also performed to study the role of local adaptation and selection as compared to long distance migration of spores. The rust is pathotyped and analysed by AFLP to reveal the relatedness with european rust and analyze the level of long distance exchange. Possible exchange of virulence factors between the continents is of utmost importance for the outcome of the resistance breeding and longevity of the new more resistant clones.

    Comment comprendre la physique ? Comment savoir pourquoi il y a des particules et des antiparticules, ou dans quel état se trouve le chat de Schrödinger ? Comment découvrir ce qui se conserve dans la nature ? Comment s'initier aux théories à la pointe de notre connaissance de l'Univers ? Ce livre veut aider à parler la physique, à apprendre son vocabulaire. Chaque mot est défini dans son sens immédiat comme dans ses significations plus complexes. Et les renvois d'un mot à l'autre permettent de saisir la physique en bloc. Après Les atomes existent-ils vraiment ? et Traité de physique à l'usage des profanes, Bernard Diu fait partager, sous une nouvelle forme, sa passion pour la physique. A le lire, il ne fait aucun doute qu'Einstein avait raison : " Subtil est le Créateur. "

    We report the experimental realization of a magneto-optical trap (MOT) of 174Yb atoms operating on the 1S0-3p1 intercombination transition at 555.8 nm.The green MOT is loaded by a Zeeman-slowed atomic beam.In order to increase the capture velocity of the MOT,we use the trapping laser beams consisting of five discrete frequency components obtained by modulating the laser light through an electro-optic modulator.The trapped atomic number of the 174 Yb isotope is about 6.2×105,and the temperature of the cold atowic cloud is estimated to be about 100 μK.The success of the green MOT is an important step towards the goad of an ytterbium optical dock.

    2012-01-01

    Small deformations of marginally outer trapped surfaces (MOTS) are studied by using the stability operator introduced by Andersson-Mars-Simon. Novel formulae for the principal eigenvalue are presented. A characterization of the many marginally outer trapped tubes (MOTT) passing through a given MOTS is given, and the possibility of selecting a privileged MOTT is discussed. This is related to the concept of `core' of a black hole: a minimal region that one should remove from the spacetime in order to get rid of all possible closed trapped surfaces. In spherical symmetry one can prove that the spherical MOTT is the boundary of a core. I argue how similar results may hold in general spacetimes.

    We report on progress toward a magneto-optical trap (MOT) of CaF molecules. While following the same essential approach as that used to laser cool SrF and YO, we are developing direct MOT loading from a 2-stage cryogenic buffer gas beam (CBGB) source. This source has a lower forward velocity compared to the hydrodynamic CBGB source that was employed with SrF and YO. We report the creation of the first CBGB loaded MOTs, without the use of a Zeeman slower, for Ho, Yb, Er, and Tm. The slower initial beam velocity of the two-stage CBGB should aid in MOT loading of molecules, which have inherently low MOT capture velocities (~ 10 m/s). We plan to implement an AC-MOT for CaF, and report on theoretical studies and experimental progress toward that goal.

    Eftersom organisationsförändringar i New Public Management filosofins fotspår har blivit allt vanligare i svenska kommuner, ofta med oklara regler som följd, menar flera forskare att en ny riskzon för korruption kan ha uppstått också i det traditionellt icke-korrupta Sverige. Genom att påbörja den empiriska kartläggningen av hur korruption upplevs bland politiskt ansvariga i Sveriges kommuner syftar artikeln till att granska om det finns någon grund för denna misstanke. Resultaten visar att den formaliserade uppmärksamheten kring korruption är långt mer utvecklad i de kommuner som tidigt införde kundvalssystem. Sambandet mellan en högre grad av formaliserad uppmärksamhet mot korruption och införandet av kundvalssystem håller också med kontroll för kommunens befolkningsstorlek. Trots att artikeln inte kan säga något om den faktiska utbredningen av korruption i svenska kommuner visar resultaten att politiker och tjänstemän i kommuner som mer helhjärtat än andra har genomfört långtgående marknadsreformer själva tycks bedöma att det finns en risk för korruption. Följaktligen ger resultaten indikationer om att formella åtgärder mot korruption i svenska kommuner är mer omfattande där teoretiska förväntningar gör gällande att riskerna är mest utbredda.

    Ultra-cold diatomic molecules have rich prospects as candidates to study controlled ultra-cold chemistry, strongly correlated systems and precision measurements. They are also considered as possible qubits in quantum computing and simulation schemes. We report on progress towards loading CaF into a molecular magneto-optical trap (MOT). An AC-MOT will be used to actively remix magnetic dark states via both polarization and magnetic field switching. In order to load a molecular MOT, we have successfully laser slowed a CaF beam to near the expected capture velocity. We describe our AC-MOT apparatus, which is designed to co-trap CaF and Li. We outline our planned study of CaF-Li collisions to explore the feasibility of sympathetically cooling molecules to ultra-cold temperatures.

    A Cs-133 Magneto-Optical Trap (MOT) has been developed at the Time and Frequency Division of the Centro Nacional de Metrologia, CENAM, in Mexico. This MOT is part of a primary frequency standard based on ultra-cold Cs atoms, called CsF-1 clock, under development at CENAM. In this Cs MOT, we use the standard configuration ({sigma}{sup +} - {sigma}{sup -}) 4-horizontal 2-vertical laser beams 1.9 cm in diameter, with 5 mW each. We use a 852 nm, 5 mW, DBR laser as a master laser which is stabilized by saturation spectroscopy. Emission linewidth of the master laser is l MHz. In order to amplify the light of the master laser, a 50 mW, 852 nm AlGaAs laser is used as slave laser. This slave laser is stabilized by light injection technique. A 12 MHz red shift of the light is performed by two double passes through two Acusto-Optic Modulators (AOMs). The optical part of the CENAMs MOT is very robust against mechanical vibration, acoustic noise and temperature changes in our laboratory, because none of our diode lasers use an extended cavity to reduce the linewidth. In this paper, we report results of our MOT characterization as a function of several operation parameters such as the intensity of laser beams, the laser beam diameter, the red shift of light, and the gradient of the magnetic field. We also report accurate absolute measurement of the number of Cs atoms trapped in our Cs MOT. We found up to 6 x 10{sup 7} Cs atoms trapped in our MOT measured with an uncertainty no greater than 6.4%. (Author)

    The Maidanak One-meter Telescope (MOT) is a Ritchey-Chretien telescope by Carl Zeiss, located atop Maidanak in Uzbekistan, where site parameters indicate excellent atmospheric seeing conditions. An effort to computerize the MOT, jointly made by an Uzbek, Taiwanese and Baltic consortium, is expected to complete in 2005. Monitoring the variability of star clusters will be among the first scientific projects to be carried out. Equipped with sensitive CCD cameras, the MOT, with its middle-Asia geographic location, will be a desirable addition to the Whole Earth Telescope (WET) network.We describe the upgrade engineering and instrumentation of the telescope and how the system can be used in future campaigns.

  12. An N-terminal Region of Mot-2 Binds to p53 In Vitro

    Full Text Available The mouse mot-2 protein was earlier shown to bind to the tumor suppressor protein, p53. The mot-2 binding site of p53 was mapped to C-terminal amino acid residues 312–352, which includes the cytoplasmic sequestration domain. In the present study, we have found that both mot-1 and mot-2 bind to p53 in vitro. By using His-tagged deletion mutant proteins, the p53-binding domain of mot-2 was mapped to its Nterminal amino acid residues 253–282, which are identical in mot-1 and mot-2 proteins. Some peptides containing the p53-binding region of mot-2 were able to compete with the full-length protein for p53 binding. The data provided rationale for in vitro binding of mot-1 and mot-2 proteins to p53 and supported the conclusion that inability of mot-1 protein to bind p53 in vivo depends on secondary structure or its binding to other cellular factors. Most interestingly, the p53-binding region of mot-2 was common to its MKT-077, a cationic dye that exhibits antitumor activity, binding region. Therefore it is most likely that MKT-077-induced nuclear translocation and restoration of wild-type p53 function in transformed cells takes place by a competitional mechanism.

    Therapeutic targeting bone loss has been the focus of the study in osteoporosis. The present study is intended to evaluate whether MOTS-c, a novel mitochondria related 16 aa peptide, can protect mice from ovariectomy-induced osteoporosis. After ovary removal, the mice were injected with MOTS-c at a dose of 5 mg/kg once a day for 12 weeks. Our results showed that MOTS-c treatment significantly alleviated bone loss, as determined by micro-CT examination. Mechanistically, we found that the receptor activator of nuclear factor-κB ligand (RANKL) induced osteoclast differentiation was remarkably inhibited by MOTS-c. Moreover, MOTS-c increased phosphorylated AMPK levels, and compound C, an AMPK inhibitor, could partially abrogate the effects of the MOTS-c on osteoclastogenesis. Thus, our findings provide evidence that MOTS-c may exert as an inhibitor of osteoporosis via AMPK dependent inhibition of osteoclastogenesis. -- Highlights: •MOTS-c decreases OVX-induced bone loss in vivo. •MOTS-c inhibits RANKL-induced osteoclast formation. •MOTS-c inhibits RANKL-induced osteoclast-specific gene expression. •MOTS-c represses osteoclast differentiation via the activation of AMPK.

    The essential Saccharomyces cerevisiae ATPase Mot1 globally regulates transcription by impacting the genomic distribution and activity of the TATA-binding protein (TBP). In vitro, Mot1 forms a ternary complex with TBP and DNA and can use ATP hydrolysis to dissociate the TBP-DNA complex. Prior work suggested an interaction between the ATPase domain and a functionally important segment of DNA flanking the TATA sequence. However, how ATP hydrolysis facilitates removal of TBP from DNA is not well understood, and several models have been proposed. To gain insight into the Mot1 mechanism, we dissected the role of the flanking DNA segment by biochemical analysis of complexes formed using DNAs with short single-stranded gaps. In parallel, we used a DNA tethered cleavage approach to map regions of Mot1 in proximity to the DNA under different conditions. Our results define non-equivalent roles for bases within a broad segment of flanking DNA required for Mot1 action. Moreover, we present biochemical evidence for two distinct conformations of the Mot1 ATPase, the detection of which can be modulated by ATP analogs as well as DNA sequence flanking the TATA sequence. We also show using purified complexes that Mot1 dissociation of a stable, high affinity TBP-DNA interaction is surprisingly inefficient, suggesting how other transcription factors that bind to TBP may compete with Mot1. Taken together, these results suggest that TBP-DNA affinity as well as other aspects of promoter sequence influence Mot1 function in vivo.

    Are Master of Occupational Therapy (MOT) graduates more successful than BS graduates in accessing and analyzing research literature? This retrospective cohort study used a survey sent to Ohio State University MOT graduates, asking why they need information for their practice, what types of information they seek, and how they search for and use it. Results suggest that the MOT program has fostered higher-level skills than did the BS program in independent writing, a greater focus on evidence-based practice, and the use of bibliographic databases. The MOT graduates report high confidence in their ability to apply research to practice and high satisfaction with the lifelong learning skills they learned. The survey findings support the importance of collaboration between Occupational Therapy faculty and medical librarians in developing MOT educational programs.

  20. MOT solution of the PMCHWT equation for analyzing transient scattering from conductive dielectrics

    KAUST Repository

    Uysal, Ismail Enes

    2015-01-01

    Transient electromagnetic interactions on conductive dielectric scatterers are analyzed by solving the Poggio-Miller-Chan-Harrington-Wu-Tsai (PMCHWT) surface integral equation with a marching on-in-time (MOT) scheme. The proposed scheme, unlike the previously developed ones, permits the analysis on scatterers with multiple volumes of different conductivity. This is achieved by maintaining an extra temporal convolution that only depends on permittivity and conductivity of these volumes. Its discretization and computation come at almost no additional cost and do not change the computational complexity of the resulting MOT solver. Accuracy and applicability of the MOT-PMCHWT solver are demonstrated by numerical examples.

    Tanner, T.

    2006-07-01

    Being supported by an international collaboration the project ProMot has developed and disseminated in the European Union a decision support tool for electric motor users helping them to choose energy efficient motor systems. During the first phase all necessary components to build the decision support tool have been selected, developed or improved and adapted. At the beginning it was assumed that the contribution of the author's company, Semafor would be the integration of the company's OPAL software components developed for pumps and variable speed drives (VSD) into the EuroDEEM package. In view of the deficiencies of EuroDEEM it was soon agreed to abandon this approach. Instead, the package IMSSA (International Motor Selection and Saving Analysis), developed at the Washington State University on the basis of MotorMaster was selected. IMSSA - which has been renamed to EuroDEEM International - and the pump and VSD module can now be used as standalone applications. The second phase integrated all collected and developed material into a comprehensive and user-friendly web site that was then demonstrated to key actors in the participating countries. Several requirements had to be considered. The platform had to allow the publication of the web pages in several languages and to enable the team members to place and modify their content without disturbing ongoing operation. It was therefore decided to evaluate a suitable Web Content Management System (CMS) which lead to Plone, a powerful and adaptable open-source system already in use at many web sites. The pages have then been created and published with this system. With some support from Semafor, German and French translations were created. Also a hardcopy brochure that gives an overview of the web site has been produced and distributed in the participating countries. (author)

The objective of this study was to further validate the MOT-Q in 122 inpatients and 92 outpatients with acquired brain injury (ABI). The main measures were motivation for rehabilitation (MOT-Q), self-awareness (Patient Competency Rating Scale), and treatment motivation (Visual Analogue Scale). The MOT-Q showed adequate feasibility in terms of few items with missing responses and few undecided responses. We found no floor or ceiling effects, and significant item-total MOT-Q correlations for 29 of 31 items. Internal consistency was good for the MOT-Q total and acceptable to good for the subscales. The MOT-Q scores were significantly intercorrelated except for the subscales Lack of denial and Reliance on professional help in the inpatient group. The MOT-Q total and subscales were significantly associated with treatment motivation. The Lack of denial subscale showed no significant association with treatment motivation and no to moderate significant associations with self-awareness. In conclusion, the overall MOT-Q is a valid instrument to assess motivation for rehabilitation in patients with ABI. Further research is needed to examine the validity of the subscales.

  8. On the DC loop modes in the MOT solution of the time domain EFIE

    2014-07-01

    When marching-on-in-time (MOT) method is applied to solve the time domain electric field integral equation (TD-EFIE), DC loop modes are always observed in the solution. In theory these modes should not be observed since they do not satisfy the relaxed initial conditions. Their appearance is attributed to numerical errors. It is shown here that when Rao-Wilton-Glisson basis and Lagrange interpolation functions are used to discretize the TD-EFIE, errors due to this space-time discretization have zero impact on the DC loop modes. Numerical experiments demonstrate that the numerical errors due to approximate solution of the MOT matrix system have more dominant impact on DC loop modes in the MOT solution.

    An explicit marching on-in-time (MOT) scheme for solving the time domain electric field integral equation enforced on volumes with time varying dielectric permittivity is proposed. Unknowns of the integral equation and the constitutive relation, i.e., flux density and field intensity, are discretized using full and half Schaubert-Wilton-Glisson functions in space. Temporal interpolation is carried out using band limited approximate prolate spherical wave functions. The discretized coupled system of integral equation and constitutive relation is integrated in time using a PE(CE)m type linear multistep scheme. Unlike the existing MOT methods, the resulting explicit MOT scheme allows for straightforward incorporation of the time variation in the dielectric permittivity.

    The second messenger cyclic diguanylate (c-di-GMP) plays a critical role in the regulation of motility. In Pseudomonas aeruginosa PA14, c-di-GMP inversely controls biofilm formation and surface swarming motility, with high levels of this dinucleotide signal stimulating biofilm formation and repressing swarming. P. aeruginosa encodes two stator complexes, MotAB and MotCD, that participate in the function of its single polar flagellum. Here we show that the repression of swarming motility requires a functional MotAB stator complex. Mutating the motAB genes restores swarming motility to a strain with artificially elevated levels of c-di-GMP as well as stimulates swarming in the wild-type strain, while overexpression of MotA from a plasmid represses swarming motility. Using point mutations in MotA and the FliG rotor protein of the motor supports the conclusion that MotA-FliG interactions are critical for c-di-GMP-mediated swarming inhibition. Finally, we show that high c-di-GMP levels affect the localization of a green fluorescent protein (GFP)-MotD fusion, indicating a mechanism whereby this second messenger has an impact on MotCD function. We propose that when c-di-GMP level is high, the MotAB stator can displace MotCD from the motor, thereby affecting motor function. Our data suggest a newly identified means of c-di-GMP-mediated control of surface motility, perhaps conserved among Pseudomonas, Xanthomonas, and other organisms that encode two stator systems.

    2016-11-02

    A marching on-in-time (MOT) scheme for analyzing transient electromagnetic wave interactions on devices consisting of graphene sheets and dielectric substrates is proposed. The MOT scheme discretizes time domain resistive boundary condition (TD-RBC) and Poggio-Miller-Chang-Harrington-Wu-Tsai (TD-PMCHWT) integral equation, which are enforced on the surfaces of the graphene and dielectric substrate, respectively. The expressions of the time domain resistivity and conductivity of the graphene sheet are obtained analytically from the intra-band contribution formulated in frequency domain. Numerical results, which demonstrate the applicability of the proposed scheme, are presented.

    A marching on in time (MOT) scheme for solving the Poggio-Miller-Chan-Harrington-Wu-Tsai (PMCHWT) surface integral equation on plasmonic nanostructures is described. The proposed scheme calls for temporal convolutions of the permittivity and Green function of the plasmonic medium with the temporal basis function. Time domain samples of the permittivity and the Green function required by these convolutions are computed using a fast relaxed vector fitting (FRVF) algorithm. Numerical results demonstrate the accuracy and applicability of the proposed MOT-PMCHWT solver.

  13. Variation in molybdenum content across broadly distributed populations of Arabidopsis thaliana is controlled by a mitochondrial molybdenum transporter (MOT1.

    2008-02-01

    Full Text Available Molybdenum (Mo is an essential micronutrient for plants, serving as a cofactor for enzymes involved in nitrate assimilation, sulfite detoxification, abscisic acid biosynthesis, and purine degradation. Here we show that natural variation in shoot Mo content across 92 Arabidopsis thaliana accessions is controlled by variation in a mitochondrially localized transporter (Molybdenum Transporter 1 - MOT1 that belongs to the sulfate transporter superfamily. A deletion in the MOT1 promoter is strongly associated with low shoot Mo, occurring in seven of the accessions with the lowest shoot content of Mo. Consistent with the low Mo phenotype, MOT1 expression in low Mo accessions is reduced. Reciprocal grafting experiments demonstrate that the roots of Ler-0 are responsible for the low Mo accumulation in shoot, and GUS localization demonstrates that MOT1 is expressed strongly in the roots. MOT1 contains an N-terminal mitochondrial targeting sequence and expression of MOT1 tagged with GFP in protoplasts and transgenic plants, establishing the mitochondrial localization of this protein. Furthermore, expression of MOT1 specifically enhances Mo accumulation in yeast by 5-fold, consistent with MOT1 functioning as a molybdate transporter. This work provides the first molecular insight into the processes that regulate Mo accumulation in plants and shows that novel loci can be detected by association mapping.

    Objective To determine the role of flagellar motor protein MotA in the pathogenesisassociated chemotaxis and colonization of Campylobacter jejuni. Methods The motA gene as well as Kan~r gene and plus-motA gene segments for motA gene knock-out were amplified by PCR and the target amplification fragments were sequenced after cloning. A suicide plasmid(pBlueskrit-Ⅱ-SK~(motA-kan)) and a motA gene knock-out mutant (motA~-) were constructed based on homologious recombination. By using semisolid plate migration test, hard agar plus (HAP)-based chemotactic test towards sodium deoxycholate (SDC) in vitro, and jejunal colonization test in BALB/c-ByJ mice were performed to determine the differences of flagellar motility, chemotaxis towards SDC and colonization in murine jejunum between motA~- mutant and wild-type strain. Results The nucleotide and amino acid sequences of the cloned motA gene were 100% identical to the reported corresponding sequences. The results of PCR, sequencing and continuous passage culture in antibiotics-contained medium demonstrated that both suicide plasmid and motA~- mutant were successfully generated. The diameters of clonies on semisolid plate and 0.2 mol/L SDC-induced chemotactic tings in HAP as well as the bacterial numbers adhering to the surface of murine jejunal mucosa and in jejunal content of motA~- mutant were significantly less than those of wild-type strain(P<0.05). Conclusion A motA gene knock-out mutant of C. jejuni was successfully constructed in this study, motA is an essential gene for flagellax motility, pathogenesis-associated chemotaxis and colonization of C. jejuni.%目的 确定鞭毛马达蛋白(flagellar motor protein)MotA编码基因在空肠弯曲菌(Campylobacter jejuni)致病性相关趋化和定植中的作用.方法 采用PCR扩增motA基因以及用于motA基因敲除的Kan~r基因和plus-motA基因片段,目的扩增产物克隆后测序.根据同源重组原理,构建空肠弯曲菌NCTC11168株motA基因自杀质

    2011-07-01

    The detection of functional motifs is an important step for the determination of protein functions. We present here a new web server SA-Mot (Structural Alphabet Motif) for the extraction and location of structural motifs of interest from protein loops. Contrary to other methods, SA-Mot does not focus only on functional motifs, but it extracts recurrent and conserved structural motifs involved in structural redundancy of loops. SA-Mot uses the structural word notion to extract all structural motifs from uni-dimensional sequences corresponding to loop structures. Then, SA-Mot provides a description of these structural motifs using statistics computed in the loop data set and in SCOP superfamily, sequence and structural parameters. SA-Mot results correspond to an interactive table listing all structural motifs extracted from a target structure and their associated descriptors. Using this information, the users can easily locate loop regions that are important for the protein folding and function. The SA-Mot web server is available at http://sa-mot.mti.univ-paris-diderot.fr.

  16. An explicit MOT-TDVIE scheme for analyzing electromagnetic field interactions on nonlinear scatterers

    2015-02-01

    An explicit marching on-in-time (MOT) based time domain electric field volume integral equation (TDVIE) solver for characterizing electromagnetic wave interactions on scatterers with nonlinear material properties is proposed. Discretization of the unknown electric field intensity and flux density is carried out by half and full Schaubert-Wilton-Glisson basis functions, respectively. Coupled system of spatially discretized TDVIE and the nonlinear constitutive relation between the field intensity and the flux density is integrated in time to compute the samples of the unknowns. An explicit PE(CE)m scheme is used for this purpose. Explicitness allows for \\'easy\\' incorporation of the nonlinearity as a function only to be evaluated on the right hand side of the coupled system of equations. A numerical example that demonstrates the applicability of the proposed MOT scheme to analyzing electromagnetic interactions on Kerr-nonlinear scatterers is presented. © 2015 IEEE.

    This paper presents design of a novel modular lower-limb gait exoskeleton built within the FP7 BioMot project. Exoskeleton employs a variable stiffness actuator in all 6 joints, a directional-flexibility structure and a novel physical humanrobot interfacing, which allows it to deliver the required output while minimally constraining user's gait by providing passive degrees of freedom. Due to modularity, the exoskeleton can be used as a full lower-limb orthosis, a single-joint orthosis in any of the three joints, and a two-joint orthosis in a combination of any of the two joints. By employing a simple torque control strategy, the exoskeleton can be used to deliver user-specific assistance, both in gait rehabilitation and in assisting people suffering musculoskeletal impairments. The result of the presented BioMot efforts is a low-footprint exoskeleton with powerful compliant actuators, simple, yet effective torque controller and easily adjustable flexible structure.

    2016-06-01

    Moving Object Tracking (MOT) is one of the frequent used tasks in computer vision systems and on the same time a challenging issue particularly in darkness. Vehicle tracking involves finding new position of vehicles in consecutive frames. This paper presents MOT algorithm that is developed for advanced driver safety applications like automatic high beam control, forward collision warning. Accordingly, the proposed approach targets vehicle tracking in the dark environment. Hence, a camera is mounted on the host vehicle to capture video frames of the traffic ahead. The scope involves tracking of both oncoming and preceding vehicles. The vehicles are tracked in consecutive frames using grayscale information and robust structure features. The features representation of the vehicle region is based on cumulative pixel intensity information. The implementation for feature extraction is optimized by using a dynamic programming approach to meet the constraints of a real time application. Simulation results thus obtained are promising in state of the art.

  20. On spurious resonant modes in the MOT solution of time domain EFIE

    KAUST Repository

    Shi, Yifei

    2013-07-01

    Theoretically, internal resonant modes should not be induced in the marching-on-in-time (MOT) solution of the time domain electric field integral equation since zero initial conditions are enforced at the beginning of time marching and the internal resonant modes do not satisfy these initial conditions. However, these spurious modes are always observed in the MOT solution. It has been conjectured in the past that numerical errors might establish the necessary initial conditions and allow the incident field to induce the internal resonant modes. Systematic numerical experiments carried out in this work prove this conjecture by demonstrating that the internal resonant modes\\' amplitudes are indeed dictated by the numerical errors and the spectrum of the incident field. © 2013 IEEE.

    2014-08-07

    The transmit array of multi-overlapped-transmit-subarray configured bistatic multiple-input multiple-output (MOTS MIMO) radar is partitioned into a number of overlapped subarrays, which is different from the traditional bistatic MIMO radar. In this paper, a new unitary ESPRIT scheme for joint estimation of the direction of departure (DOD) and the direction of arrival (DOA) for MOTS MIMO radar is proposed. In our method, each overlapped-transmit-subarray (OTS) with the identical effective aperture is regarded as a transmit element and the characteristics that the phase delays between the two OTSs is utilized. First, the measurements corresponding to all the OTSs are partitioned into two groups which have a rotational invariance relationship with each other. Then, the properties of centro-Hermitian matrices and real-valued rotational invariance factors are exploited to double the measurement samples and reduce computational complexity. Finally, the close-formed solution of automatically paired DOAs and DODs of targets is derived in a new manner. The proposed scheme provides increased estimation accuracy with the combination of inherent advantages of MOTS MIMO radar with unitary ESPRIT. Simulation results are presented to demonstrate the effectiveness and advantage of the proposed scheme.

    The cloning, overexpression, purification, crystallization and preliminary X-ray diffraction analysis of a putative peptidoglycan-binding domain of H. pylori MotB, a stator component of the bacterial flagellar motor, are reported. The C-terminal domain of MotB (MotB-C) contains a putative peptidoglycan-binding motif and is believed to anchor the MotA/MotB stator unit of the bacterial flagellar motor to the cell wall. Crystals of Helicobacter pylori MotB-C (138 amino-acid residues) were obtained by the hanging-drop vapour-diffusion method using polyethylene glycol as a precipitant. These crystals belong to space group P2{sub 1}, with unit-cell parameters a = 50.8, b = 89.5, c = 66.3 Å, β = 112.5°. The crystals diffract X-rays to at least 1.6 Å resolution using a synchrotron-radiation source. Self-rotation function and Matthews coefficient calculations suggest that the asymmetric unit contains one tetramer with 222 point-group symmetry. The anomalous difference Patterson maps calculated for an ytterbium-derivative crystal using diffraction data at a wavelength of 1.38 Å showed significant peaks on the v = 1/2 Harker section, suggesting that ab initio phase information could be derived from the MAD data.

  4. Laser Slowing of CaF Molecules and Progress towards a Dual-MOT for Li and CaF

    Science.gov (United States)

    Chae, Eunmi

    Diatomic molecules are considered good candidates for the study of strongly correlated systems and precision measurement searches due to their combination of complex internal states and strong long-range interactions. Cooling molecules down to ultracold temperatures is often a necessary step for fully utilizing the power of the molecule. This requires a trap for molecules and the ability to cool molecules to the mK regime and below. A magneto-optical trap (MOT) is a good tool for achieving mK temperatures. However, extra care is needed for molecules to form the necessary quasi-closed cycling transitions due to molecule's complicated energy structure. In our work with CaF, we use two repump lasers to block vibrational leakage and selection rules for the rotational degree of freedom to achieve about 105 photon cycles. The two-stage buffer gas beam source is a general method to generate a cold and slow beam of molecules with a forward velocity of about 50 m/s. The compatibility of the buffer-gas source with a MOT is studied and we confirm that such beams can be nicely compatible with MOTs using various atomic species. In order to load molecules into a MOT from even such a slow beam, additional slowing is required due to the low capture velocity of a molecular MOT (trapped. These are crucial ingredients for co-trapping CaF molecules and Li atoms and study their collisional properties, which would lead to sympathetic cooling of molecules down to ultracold temperatures. The achievement of slowing and development of this system allowed for the detailed study of the CaF laser cooling system, as well as physical processes involved with AC MOTs and the proposed MOT for CaF. Crucial knowledge of this archetypal system provides significant progress toward manipulation and control of molecules similar to what has been achieved with atoms and what is necessary for searches for new physics with ultracold molecules.

    Laser slowing of CaF molecules down to the capture velocity of a magneto-optical trap (MOT) for molecules is achieved. Starting from a two-stage buffer gas beam source, we apply frequency-broadened "white-light" slowing and observe approximately 6x10^4 CaF molecules with velocities near 10\\,m/s. CaF is a candidate for collisional studies in the mK regime. This work represents a significant step towards magneto-optical trapping of CaF.

    2016-10-25

    The bacterial flagellar motor is a rotary motor complex composed of various proteins. The motor contains a central rod, multiple ring-like structures and stators. The Na(+)-driven polar flagellar motor of the marine bacterium Vibrio alginolyticus has a specific ring, called the 'T-ring', which consists of two periplasmic proteins, MotX and MotY. The T-ring is essential for assembly of the torque-generating unit, the PomA/PomB stator complex, into the motor. To investigate the role of the T-ring for motor function, we performed random mutagenesis of the motX gene on a plasmid. The isolated MotX mutants showed nonmotile, slow-motile, and up-motile phenotypes by the expression from the plasmid. Deletion analysis indicated that the C-terminal region and the signal peptide in MotX are not always essential for flagellar motor function. We also found that overproduction of MotX caused the delay of growth and aberrant cell shape. MotX might have unexpected roles not only in flagellar motor function but also in cell morphology control.

    ot-2 protein is shown to interact with p53 and inhibit its transcriptional activation function.Mot-2 overexpressing stable clones of NIH 3T3 cells were malignantly transformed,however,they had a high level of expression of a p53 downstream gene,P21waf1.The present study was undertaken to elucidate possible molecular mechanism(s) of such upregulation.An increased level of P21waf1 expression was detected in stable transfectants although an exogenous reporter gene driven by P21waf1 promoter exhibited lower activity in these cells suggesting that some post-transcriptional mechanism contributes to upregulation.Western analyses of transient and stable clones revealed that upregulation of P21waf1 in stable NIH 3T3/mot-2 cells may be mediated by cyclin D1 and cdk-2.

    The Canary Islands Long-Baseline Observatory (CILBO) is a double station meteor camera system (Koschny et al., 2013; Koschny et al., 2014) that consists of 5 cameras. The two cameras considered in this report are ICC7 and ICC9, and are installed on Tenerife and La Palma. They point to the same atmospheric volume between both islands allowing stereoscopic observation of meteors. Since its installation in 2011 and the start of operation in 2012 CILBO has detected over 15000 simultaneously observed meteors. Koschny and Diaz (2002) developed the Meteor Orbit and Trajectory Software (MOTS) to compute the trajectory of such meteors. The software uses the astrometric data from the detection software MetRec (Molau, 1998) and determines the trajectory in geodetic coordinates. This work presents a Monte-Carlo based extension of the MOTS code to compute the orbital elements of simultaneously detected meteors by CILBO.

    Full Text Available Det pedagogiska ledarskapet inom högre utbildning fokuseras allt mer. Det understryks genom att flera lärosäten föreskriver såväl att pedagogiska ledare ska finnas på olika nivåer, som vilka övergripande uppgifter dessa ska ha. Denna artikel är ett resultat av en fallstudie av hur de tillägnade kunskaperna och färdigheterna från kursen Pedagogiskt ledarskap, en kurs för målgruppen studierektorer/pedagogiskt ansvariga eller motsvarande arrangerad av Universitetspedagogiskt centrum, har bidragit till deltagarnas professionalisering av det pedagogiska ledarskapet ett år efter kursens slut. Fallstudien genomfördes genom gruppintervjuer. Respondenterna uttryckte att de fått ett stärkt självförtroende i rollen som pedagogiska ledare samt att kursen bidrog till en professionalisering av rollen som pedagogiska ledare genom att stärka identiteten, att skapa en början till en handlingsetik bestående av delvis delade värderingar kring det pedagogiska ansvaret samt ge utbildning och träning i färdigheter som har sin grund i teoretisk kunskap. Kursen Pedagogiskt ledarskap ger därmed ett stöd i en process mot en professionalisering av det pedagogiska ledarskapet vid Umeå universitet.

  17. Crystallographic and molecular dynamics analysis of loop motions unmasking the peptidoglycan-binding site in stator protein MotB of flagellar motor.

    Directory of Open Access Journals (Sweden)

    Cyril F Reboul

    Full Text Available BACKGROUND: The C-terminal domain of MotB (MotB-C shows high sequence similarity to outer membrane protein A and related peptidoglycan (PG-binding proteins. It is believed to anchor the power-generating MotA/MotB stator unit of the bacterial flagellar motor to the peptidoglycan layer of the cell wall. We previously reported the first crystal structure of this domain and made a puzzling observation that all conserved residues that are thought to be essential for PG recognition are buried and inaccessible in the crystal structure. In this study, we tested a hypothesis that peptidoglycan binding is preceded by, or accompanied by, some structural reorganization that exposes the key conserved residues. METHODOLOGY/PRINCIPAL FINDINGS: We determined the structure of a new crystalline form (Form B of Helicobacter pylori MotB-C. Comparisons with the existing Form A revealed conformational variations in the petal-like loops around the carbohydrate binding site near one end of the β-sheet. These variations are thought to reflect natural flexibility at this site required for insertion into the peptidoglycan mesh. In order to understand the nature of this flexibility we have performed molecular dynamics simulations of the MotB-C dimer. The results are consistent with the crystallographic data and provide evidence that the three loops move in a concerted fashion, exposing conserved MotB residues that have previously been implicated in binding of the peptide moiety of peptidoglycan. CONCLUSION/SIGNIFICANCE: Our structural analysis provides a new insight into the mechanism by which MotB inserts into the peptidoglycan mesh, thus anchoring the power-generating complex to the cell wall.

  18. Contraintes de taille dans les mots composés : quand la phonologie entre en concurrence avec les contraintes morphologiques

    2012-07-01

    Full Text Available Cette communication porte sur les contraintes phonologiques qui pèsent sur la formation des mots construits dans le cadre théorique de la morphologie lexématique (Anderson 1992, Aronoff 1994, Fradin 2003. En étudiant les données du français, les travaux de Lignon (à paraître, Plénat (2009 & Roché (2003 ont montré que des contraintes de taille étaient à l’œuvre dans plusieurs constructions morphologiques. L’objectif de cet article est d’étudier cette hypothèse sur les mots composés Verbe-Nom du français (Villoing 2009. L’analyse quantitative des données du corpus montre clairement que les verbes des mots composés VN du français sont soumis à des contraintes de taille et doivent répondre au format d’un monosyllabe. La contrainte pèse moins lourdement sur les noms qui parviennent à s’imposer plus facilement que les verbes avec une taille supérieure. Cependant, la majorité des mots composés VN tend à ne pas dépasser trois syllabes (leur format optimal étant de deux ou trois syllabes, révélant ainsi l'influence des contraintes de taille sur le mot composé lui-même. La mise au jour de ces contraintes permet d'expliquer l’absence de certains verbes dans le corpus de composés VN, répondant pourtant bien aux propriétés sémantiques attendues : les verbes construits par affixation (absence de suffixés en -iser, -ifier; très rares cas de préfixés, les verbes du 2ème groupe, les verbes de taille supérieure à trois syllabes. En outre, cet article met au jour un cas de concurrence entre contrainte morphologique et contrainte phonologique au sein d'une construction morphologique, et montre comment la première l'emporte sur la dernière, bien que la contrainte phonologique contraigne fortement le choix du verbe et du nom de base. Il donne également à voir comment la contrainte phonologique parvient néanmoins à influencer le choix de bases sémantiquement peu conformes aux attentes de la règle.

    MKT-077, a cationic rhodacyanine dye analogue has been under preclinical cancer therapeutical trials because of its selective toxicity to cancer cells. Its cellular targets and mechanism of action remain poorly understood. Here we report that MKT-077 binds to an hsp70 family member, mortalin (mot-2), and abrogates its interactions with the tumor suppressor protein, p53. In cancer cells, but not in normal cells, MKT-077 induced release of wild-type p53 from cytoplasmically sequestered p53-mot-2 complexes and rescued its transcriptional activation function. Thus, MKT-077 may be particularly useful for therapy of cancers with wild-type p53.

    Full Text Available En 1709, la localidad de Tumaco, situada en el noroeste de la Audiencia de Quito, fue escenario de un motín que enfrentó a los vecinos principales de la localidad con varios jueces enviados por las autoridades quiteñas. El enfrentamiento se remite al contexto de redefi nición del modelo de ocupación territorial en los Andes septentrionales a comienzos del siglo XVIII. El análisis del expediente conservado en el Archivo Nacional de Historia de Quito permite observar el papel de la violencia como elemento articulador de las relaciones sociales en todos los ámbitos y, al mismo tiempo, obliga a matizar los estudios demasiado optimistas que en los últimos años se han centrado en la capacidad de agencia de los actores subalternos en las regiones de frontera.

Trata-se, nesse caso, de elaborar um comentário sobre o livro chamando a atenção para as inúmeras possibilidades que abre para uma "antropologia da feitiçaria". Destaco, entre muitas, o uso cuidadoso que a autora faz do que hoje chamaríamos de um "procedimento de equivalência" ou "princípio de simetria", a saber, do modo através do qual a etnografia e a feitiçaria, situadas em um mesmo "plano de imanência", descrevem-se mutuamente, dispondo-se em uma relação recíproca de transformação.This article discusses the relationship between ethnography and witchcraft in Jeanne Favret-Saada's Les mots, la mort, les sorts (Deadly words. Its first aim is to present the main themes and concepts proposed by the author's description of witchcraft. As such, its purpose is to offer a commentary on the book by drawing attention to the various possibilities that it provides for an 'anthropology of witchcraft'. Among these, the article highlights the author's use of what we could call a 'procedure of equivalence' or 'principle of symmetry', namely the mode through which ethnography and witchcraft, when located on the same 'plane of immanence', can describe each other in a reciprocal relationship of transformation.

    2012-01-01

    Since September 2007, a large scale lexical network for French is under construction through methods based on some kind of popular consensus by means of games (JeuxDeMots project). Human intervention can be considered as marginal. It is limited to corrections, adjustments and validation of the senses of terms, which amounts to less than 0,5 % of the relations in the network. To appreciate the quality of this resource built by non-expert users (players of the game), we use a similar approach to its construction. The resource must be validated by laymen, persistent in time, on open class vocabulary. We suggest to check whether our tool is able to solve the Tip of the Tongue (TOT) problem. Just like JeuxDeMots, our tool can be considered as an on-line game. Like the former, it allows the acquisition of new relations, enriching thus the (existing) network.

  4. Mapping of ionomic traits in Mimulus guttatus reveals Mo and Cd QTLs that colocalize with MOT1 homologues.

    Directory of Open Access Journals (Sweden)

    David B Lowry

    Full Text Available Natural variation in the regulation of the accumulation of mineral nutrients and trace elements in plant tissues is crucial to plant metabolism, development, and survival across different habitats. Studies of the genetic basis of natural variation in nutrient metabolism have been facilitated by the development of ionomics. Ionomics is a functional genomic approach for the identification of the genes and gene networks that regulate the elemental composition, or ionome, of an organism. In this study, we evaluated the genetic basis of divergence in elemental composition between an inland annual and a coastal perennial accession of Mimulus guttatus using a recombinant inbred line (RIL mapping population. Out of 20 elements evaluated, Mo and Cd were the most divergent in accumulation between the two accessions and were highly genetically correlated in the RILs across two replicated experiments. We discovered two major quantitative trait loci (QTL for Mo accumulation, the largest of which consistently colocalized with a QTL for Cd accumulation. Interestingly, both Mo QTLs also colocalized with the two M. guttatus homologues of MOT1, the only known plant transporter to be involved in natural variation in molybdate uptake.

The aim of the present research was to study the effect of four chambers with different characteristics, namely; slide-coverslip, Spermtrack, ISAS D4C10, and ISAS D4C20 on the sperm motility. The filling procedure (drop or capillarity) and analysis time (0, 120 and 240s), depth of chamber (10 or 20μm) and field on motility variables were analysed by use of the CASA-mot system in goat sperm. Use of the drop-filling chambers resulted in greater values than capillarity-filling chambers for all sperm motility and kinetic variables, except for LIN (64.5% compared with 56.3% of motility for drop- and capillarity-filling chambers respectively, PCASA-mot system with a drop-loaded chamber within 2min after filling the chamber.

    Full Text Available Fremmedspråkfaget har lenge hatt et todelt formål: Det skal ha en nytteverdi, først og fremst i form av kommunikative ferdigheter, og det skal ha en allmenndannende funksjon, bl.a. gjennom tilegnelse av kunnskap om kultur og samfunn i målspråksområdet. Fra og med læreplanen for fremmedspråk i Kunnskapsløftet (2006 er det også tydelig uttrykt at dannelsesdimensjonen omfatter utvikling av interkulturell kompetanse. Denne artikkelen drøfter hvordan fagets todelte formål vil kunne forstås og realiseres i fremmedspråksundervisningen fram mot 2030. Drøftingen tar utgangspunkt i en analyse av dagens situasjon, der trenden med å stykke opp lærestoffet i håndterbare enheter og å vektlegge sterkest det som kan måles mest presist, kan gjøre at ikke-målbar kompetanse som interkulturell dannelse får en relativt svak posisjon. Det argumenteres for at pågående endringer i samfunnsutviklingen og i europeisk utdanningspolitikk vil kunne åpne for en jevnere balanse mellom nytte- og dannelsesperspektivet i faget i fremtiden. Blant disse endringene er 1 en dreining mot et mer holistisk kunnskapssyn, 2 en stadig økende heterogenitet i elevmassen, 3 større bredde i fremmedspråkstilbudet og 4 et økt fokus på flerspråklighet. Artikkelen ser nærmere på disse fire endringsprosessene og diskuterer på hvilken måte de kan og bør påvirke fortolkningen av fremmedspråkfagets todelte formål i årene som kommer.

    Negative adverbs in Korean such as “안[an]”and”못[mot]” are used to indicate negation, but they show many differences with each other in terms of syntax. The differences bring about errors on the part of Korean learners . Therefore, this paper emphatically analyzes the syntactic differences between “안[an]” and “못[mot]” mainly from the perspective of syntactic function and collocation restriction. At the same time, it compares these differences with negative adverbs “不” and “没” in Chinese, hoping that the comparison could be helpful for the students who learn Korean or Chinese as a foreign language.%韩国语否定副词“안[an]”、“못[mot]”都用来表示否定,但在句法方面存在很多差异。而这些差异也成为了韩国语学习者产生偏误的原因之一。因此,我们在文中着重分析“안[an]”和“못[mot]”的句法差异,主要从句法功能、搭配限制等方面对其进行分析。同时,和汉语中的否定副词“不”、“没”进行对比。

Quelle quantité de mots vieux et livresques doit être présente dans sa nomenclature? Est-ce qu’un mot nouveau qu’il avait recensé sera vraiment intégré au lexique de la langue décrite ? Le but de ce travail est donc d’essayer de répondre à ces questions, d’analyser la présence du lexique de ces deux types dans neuf grands dictionnaires bilingues, parus en Lituanie entre 2000 et 2006, et, enfin, définir leur rôle dans leurs macrostructures. On propose également certaines recommandations générales qui pourraient aider les futurs rédacteurs des dictionnaires à mieux équilibrer le lexique de différents types.

    Full Text Available I denne artikkelen drøfter jeg hvordan teknologi kan skape nye undervisnings- og læringsmåter i fremmedspråksundervisningen fram mot 2030. Jeg starter med å skissere et mulig framtidsscenario i form av et blogginnlegg skrevet av en 15 åring i året 2030. Videre i artikkelen tar jeg utgangspunkt i dette framtidsscenarioet og sammenligner det med dagens situasjon, i tillegg til at jeg drøfter hva som må til for at scenarioet kan oppfylles. Læreren spiller en nøkkelrolle i utviklingen av nye undervisnings- og læringsmåter, og det er først når læreren integrerer teknologien i sin undervisning at nye praksiser oppstår. Jeg viser noen konkrete eksempler på bruk av teknologi på nye måter, samt refleksjon rundt utviklingen framover.

  3. Universal non-monotonic structure in the saturation curves of MOT-loaded Na$^+$ ions stored in an ion-neutral hybrid trap: Prediction and observation

    We predict that the steady-state ion number $N_s$ for radio-frequency (rf) traps, loaded at a rate of $\\lambda$ particles per unit time, shows universal non-monotonic behavior as a function of loading rate $\\lambda$. The shape of $N_s(\\lambda)$, characterized by four dynamical regions, is universal in the sense that it is predicted to manifest itself in all rf traps independently of the details of their construction. For $\\lambda\\ll$ 1 particles / rf cycle (Region I), as expected, $N_s(\\lambda)$ increases monotonically with $\\lambda$. However, contrary to intuition, at intermediate $\\lambda \\sim 1$ particles / rf cycle (Region II), $N_s(\\lambda)$ reaches a maximum, followed by a minimum of $N_s(\\lambda)$ (Region III). For $\\lambda\\gg 1$ particles / rf cycle (Region IV), $N_s(\\lambda)$ again rises monotonically. In Region IV numerical simulations, analytical calculations, and experiments show $N_s(\\lambda)\\sim \\lambda^{2/3}$. We confirm this prediction experimentally with MOT-loaded Na$^+$ ions stored in a hyb...

  6. El lèxic cortès i cavalleresc en Curial e Güelfa: mots patrimonials i interferències culturals

    Soler, Abel

    2015-06-01

    Full Text Available Curial and Güelfa, by an unknown author, is a chivalric romance written in a realistic style. Planned within the medieval tradition, although infl uenced by Italian Humanism, it was composed in fluent Catalan, but subject to several linguistic and cultural interferences. It was probably conceived and written in Italy in the decade of 1440. The author not only knows deeply the courteous volgare language, but also the literary one (especially Boccaccio, with which he enriches a Catalan language probably learnt in Valencia. He also innovates in the courtly and chivalric vocabulary of his mother tongue with the introduction of expressions, proverbs and words –both colloquial and learned– not only in Italian, but also in French, Occitan and Spanish. All these traits help to portray a writer that knew the Lombard geography and society very well (Milano and Monferrato. However, we can deduce from the lexical field we study –among other evidence– that its lexicon could be linked to the Neapolitan court of Alphonse the Magnanimous.[ct] Curial e Güelfa, d’autoria desconeguda, és una novel·la cavalleresca, realista; planejada des de la tradició medieval, però influïda per l’Humanisme italià. Està redactada en un català fluid, però sotmès a influxos lingüistics i culturals diversos. Segurament fou concebuda i escrita a Itàlia en la dècada del 1440. L’autor no sols coneix en profunditat el volgare cortès i el literari (Boccaccio, sobretot, amb el qual “enriqueix” un català après segurament a València, sinó que a més innova en el lèxic cortès i cavalleresc de la llengua pròpia amb la introducció d’expressions, proverbis i mots –col·loquials i cultes– tant italians com també francesos, occitans i castellans. Tot plegat, ajuda molt a retratar un escriptor que coneixia bé la geografia i la societat llombardes (Milà i el Monferrat, però que, pel que permet deduir –entre altres coses– el camp l

    Marcos Eymar

    2010-09-01

    Full Text Available Le motif littéraire des derniers mots chez Vila-Matas reflète la complexité des relations du langage avec la mort. Dans ses premières œuvres, la conception de la fin s’éloigne de la quête chrétienne de salut éternel ou de la visée éthique des stoïciens, pour s’intéresser à la mort en tant qu’élaboration artistique individuelle, propice à l’ironie et le faux-semblant. À partir de Bartleby et compagnie, l’importance accordée à l’aspect comique de la mort-événement se double d’un intérêt pour la disparition de l’auteur qui exprime la recherche d’une forme de transcendance capable de mettre fin à la dérive infinie de l’écriture. Le mal de Montano tente de dépasser ce conflit métaphysique à travers une nouvelle préoccupation éthique : la mort de la littérature. In Vila-Matas's work, the literary motif of last words reflects the complex relationship between language and death. In his early work, the conception of life’s end is dissociated from the Christian search for eternal salvation, as well as from the ethical aim of the Stoics, focusing mainly upon death as an individual artistic elaboration that is particularly favourable to irony and deception. From Bartleby et compagnie onwards, the importance accorded to the comical dimension of death is coupled with an interest in the theme of the author’s disappearance, a theme that articulates the pursuit of a form of transcendence capable of putting an end to the infinitely peripatetic nature of writing. Le mal de Montano attempts to go beyond the bounds of this metaphysical conflict by raising a new ethical concern: the death of literature.

  8. Addressing the impact of environmental uncertainty in plankton model calibration with a dedicated software system: the Marine Model Optimization Testbed (MarMOT

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available A wide variety of different marine plankton system models have been coupled with ocean circulation models, with the aim of understanding and predicting aspects of environmental change. However, an ability to make reliable inferences about real-world processes from the model behaviour demands a quantitative understanding of model error that remains elusive. Assessment of coupled model output is inhibited by relatively limited observing system coverage of biogeochemical components. Any direct assessment of the plankton model is further inhibited by uncertainty in the physical state. Furthermore, comparative evaluation of plankton models on the basis of their design is inhibited by the sensitivity of their dynamics to many adjustable parameters. The Marine Model Optimization Testbed is a new software tool designed for rigorous analysis of plankton models in a multi-site 1-D framework, in particular to address uncertainty issues in model assessment. A flexible user interface ensures its suitability to more general inter-comparison, sensitivity and uncertainty analyses, including model comparison at the level of individual processes, and to state estimation for specific locations.

    The principal features of MarMOT are described and its application to model calibration is demonstrated by way of a set of twin experiments, in which synthetic observations are assimilated in an attempt to recover the true parameter values of a known system. The experimental aim is to investigate the effect of different misfit weighting schemes on parameter recovery in the presence of error in the plankton model's environmental input data. Simulated errors are derived from statistical characterizations of the mixed layer depth, the horizontal flux divergences of the biogeochemical tracers and the initial state. Plausible patterns of uncertainty in these data are shown to produce strong temporal and spatial variability in the expected simulation error over an annual

    Full Text Available Cet article se propose d’étudier une œuvre publiée en 1991 par la romancière anglaise Pat Barker : Regeneration. Ce roman, qui a pour toile de fond la Grande Guerre, ne dépeint ni combats ni scènes de la vie des tranchées. Barker préfère représenter toute la dimension agonistique de ce conflit mondial à travers la question de la prise en charge des traumatismes de guerre des soldats par l’institution psychiatrique. Ces traumatismes, ayant diverses manifestations psychosomatiques, témoignent d’une forte tension entre une profonde aversion de l’individu pour l’extrême violence des affrontements et un appel à se conformer à une certaine culture de guerre collective fondée sur un idéal fort de virilité martiale et patriotique. Face à ces traumatismes, ainsi que Pat Barker le met en lumière, la psychiatrie de guerre se révèle souvent fort ambiguë. En effet, l’institution psychiatrique œuvre en continuité avec l’institution militaire, désirant imposer un contrôle sur les âmes autant que sur les corps. Regeneration nous invite donc à lire combien les maux/mots de la Grande Guerre ont eu grand peine à se faire entendre.This article deals with a novel, entitled Regeneration, published in 1991 by the English female author Pat Barker. This novel, although set against the backdrop of World War One, depicts neither battles nor scenes of everyday life in the trenches. Instead, the agonistic dimension of this world conflict is tackled by Pat Barker through the prism of the way the psychiatric institution dealt with war traumas endured by soldiers, traumas of the body and of the mind. These traumas, causing a variety of psychosomatic symptoms, reveal a powerful tension between a deep individual aversion to the extreme violence of combat and an appeal to conform to some collective culture of war rooted in a strong ideal of soldierly and patriotic manliness. Wartime psychiatry, as Barker highlights, often turns out to

    Full Text Available El punto de partida para ofrecer una educación universitaria personalizada basada en entornos de educación online a personas con diversidad funcional debe centrarse en garantizar la óptima accesibilidad a su contenido web y a los recursos de aprendizaje. En la actualidad, la mayoría de las universidades disponen de plataformas virtuales de educación, con un importante peso para el correcto desarrollo de sus estudios y para la optimización del aprendizaje de su alumnado. Por otro lado, los entornos virtuales suponen un importante punto de acceso a la posible matriculación en dichas universidades del alumnado con discapacidad. Este trabajo tiene dos objetivos. El primero de ellos consiste en definir cuáles son las condiciones óptimas de accesibilidad web de las plataformas virtuales de educación y de los sitios web de las universidades para personas que presentan discapacidad visual o discapacidad motórica, de acuerdo a los estándares internacionales. El segundo objetivo del trabajo persigue ofrecer una breve aproximación al grado de accesibilidad de los sitios web de las universidades españolas para el alumnado con esas dos discapacidades. El trabajo sigue un diseño descriptivo basado en dos elementos de análisis. Por un lado, la revisión de estudios de accesibilidad y diversidad funcional y, por otro, el análisis de la accesibilidad web de los sitios web de las 78 universidades españolas. Se concluye que existen dificultades de accesibilidad web y navegación en los entornos virtuales de las universidades españolas, situación que, por lo tanto, redunda en limitaciones en el aprendizaje de los colectivos de estudiantes con limitaciones.

For menn er det vist at tre alkoholenheter(drinker pr. dag og for kvinner én til to, kan redusere risikoen med opptil 50%. Det synes videre som omeffekten er størst hos eldre personer (over 50 år, og de med minst én viktig koronar risikofaktor. En nyoversiktsartikkel konkluderer med at den gunstige effekten er knyttet til alkoholinnholdet og ikke til andrekomponenter for de ulike alkoholtypene. Det er presentert norske spørreskjema fra 1977 og fram til i dagvedrørende alkohol. Disse er av svært ujevn kvalitet, bl.a. uten spørsmål om mengde alkohol eller type, ogspørsmålene har variert over tid og fra fylke til fylke. Tverrsnittsdata fra Oppland (1986-88 for menn ogkvinner 40-54 år viser en positiv sammenheng mellom alkoholinntak og HDL-kolesterol for begge kjønn ogfor systolisk blodtrykk for menn, sterkest for drikkere av brennevin og øl.

For men it was shown that three units a day and forwomen one to two units can reduce mortality risk with 50%. The effect was stronger in older people (above50 years and those at greater risk for coronary heart disease. The conclusion, in a recent review, was that thebenefit is from alcohol rather than from other components of each type of drink. Norwegian questionnairesfrom 1977 to 1995 on alcohol are commented upon. The quality of these questions varies; many do notaccount for the amount of intake or the type of alcohol, and they have not been identical from screening toscreening and between counties.

    Full Text Available Fiction for all ages, books that are intended for children and adult readers alike, became an important subgenre in Norwegian literature for young readers during the 1990s. One of the crosswriters who contributed greatly to the erasing of borders between children's literature and literature for adults, is Erlend Loe, whose breakthrough novel, Naive. Super. (1996 became a cult book. It is a naive, humorous story of a man who won't grow up. Gradually, Loe's children's books about another childlike adult, Kurt the truck driver (1994, 1995, 1998, 2003, 2008, became cult literature as well. The Kurt-books are published as children's literature, but the audience has somewhat changed from children to adult readers. In this article, I discuss a problem complex of a principle nature about the limits of children's literature. Is there a limit for what is or could be children's literature? Erlend Loe's border crossing novel Kurtby (2008 is used as a relevant case study to investigate the question. In this fifth book about Kurt and his family, the setting is Sweden, in the small town Kurtby. The novel is a parody of “the Knutby case”, a tragedy that shook both Norway and Sweden in 2004, which includes religious fanaticism, adultery and murder. The publication of Kurtby attracted a great deal of attention, and it has been discussed whether the issues at stake in the Knutby case are really suitable subjects for a children's book. Does Kurtby move toward the limit of children's literature? Or, is it a move toward the limit of what can be written about with humor?

    This report concerns a research project studying biodiversity effects of partial cutting for biofuel harvest in temperate deciduous forest dominated by oaks (abandoned woodland pastures). Partial cutting (30%) resulted in fewer species of wood-decay fungi and bryophytes, but increase of vascular plants. It did not increase survival of oak seedlings in the short term. For epixylic bryophytes and lichens, wood-decay fungi, beetles and mycetophilids, area of valuable forest patches at the landscape level increased local species species richness, but not the number of red-listed and indicator species of vascular plants. We recommend that partial cutting for biofuel is not applied indiscriminantly, and a share of at least 25% of stands should be left as no intervention forests when oak grows mixed with other trees. More caution should be taken in regional areas rich in old deciduous forest, and in south-eastern Sweden.

  20. Countermeasures to corrosion on water walls. Part 2; Aatgaerder mot eldstadskorrosion paa panntuber. Etapp 2

    Background: The problems with water wall corrosion have been accelerating over the last years. There are a number of reasons for this. Originally mild steels were successfully used in power plant water walls. The magnetite layer that forms at the fire side of the tubes when the boiler is taken into operation protected from corrosion attack. The fuels at that time (oil, coal, gas) were not able to break down the magnetite by corrosion. In addition, there were no restrictions for pollutions and for the combustion itself that could contribute to corrosion attack. The usage of fossil fuels has decreased substantially over the last 25 years, not least by environmental reasons. As a replacement a number of different kinds of bio mass fuels are used. These are typically more or less corrosive and the magnetite layers are attacked. The corrosion is often supported by reducing conditions as a result of the restrictions of the NO{sub x}-pollution. Also the waste fuelled boilers have huge corrosion problems. This has been the case for the last 25 years but nowadays the number of such plants is so much higher and the service data have been turned up. Corrosion protection of the water wall tubes started to be successful in the beginning of the seventies by the introduction of the composite tube. Such tubes are fabricated by mild steel or a low alloy core and corrosion resistant austenite steel or nickel base as an about 2 mm thick corrosion protective coating. Weld cladding of the water wall tubes was introduced in the 1980's as a significantly cheaper alternative to the composite tubes. Thermal spraying and refractory protection are other methods. These corrosion protection methods have not always been effective. For example, depending on incorrect materials selection, incorrect performance and incorrect method selection for the current corrosion or erosion attack. Therefore, there is a need for increased knowledge of which protection method and material that will work economically for a given situation. In the first phase of the present project a literature survey concerning water wall corrosion protection methods was carried out [1]. Advantages, disadvantages and possibilities by the use of refractories, composite tubes, thermal spraying, hybrid coatings and weld cladding were investigated. An experience survey of problems with and protection of, water wall corrosion in Swedish plants was conducted as well. In an experimental part of the project six different weld clad materials were tested in water walls of five different boilers, representing different types of operation and fuel data. The test materials consisted of some conventional and newly developed weld clads for high temperature corrosion. These trials gave many interesting results but the exposure time was only one year of operation. A second phase of the project has now been carried out. In this study the test materials has been service exposed for another year. In addition, the literature and the experience surveys have been updated. Literature survey: There are some recent developments of water wall corrosion protection methods. One way is to flame spray relatively thick layers onto water wall sections. Then these sections were heat treated by induction heating such as the spray layers sintered see Figure 0.1 below. The sinter material consisted of 15 % Cr, 4,3 % Si, 3.1 % B and 2,5% Mo which gave very high hardness, HV 815. Three years service exposure of test panels gave no significant corrosion at all whereas carbon steel tubes exposed at the same time corroded 1.5 mm. In addition, the output of the boiler increased as a result of flame spray + sintering method. The reason is that refractory, with lower heat transfer properties, otherwise should be the solution for the water wall corrosion

    Laser slowing of CaF molecules down to the capture velocity of a magneto-optical trap for molecules is achieved. Starting from a two-stage buffer gas beam source, we apply frequency-broadened ‘white-light’ slowing and observe approximately 6× {10}4 CaF molecules in a single pulse with velocities 10 ± 4 m s-1. CaF is a candidate for collisional studies in the mK regime. This work represents a significant step towards magneto-optical trapping of CaF.

    Corrosion of water walls is becoming a problem for an increasing number of boilers. Wider use of biomass and waste for fuel, as well as requirements of reduced NO{sub x} emissions, makes it much more difficult to avoid combustion in a reducing atmosphere adjacent to the water walls. This has increased the need for corrosion protection in many existing boilers. In addition, biomass and waste fuelled plants currently being planned or built require well-functioning water wall protection from the start. The traditional water wall materials - ferritic low alloyed steels - are not easy to replace because of their outstanding heat transfer properties, ability to form a protective oxide layer on the inside of the tubes and low thermal expansion. For this reason, corrosion protection generally involves the use of some kind of coating on the tubes. In this report, the state-of-the-art regarding water wall corrosion protection is described in a literature survey. Methods covered are the use of refractories, overlay weld cladding, composite tubes and thermal spraying. The interest for overlay welding has increased recently since it can offer similar corrosion protection to composite tubes at a significantly reduced cost. Test panels have been exposed and monitored in different boilers. Six weld overlay materials were tested: the well-proven Alloy 625, a modified Alloy 625 in which niobium has been replaced by tungsten, Alloy 59, Alloy 22, a cheaper nickel base alloy 650 which contains some iron and a 310 grade stainless steel. A total of six panels were exposed in the most vulnerable positions in three different boilers. These included waste and biomass combustion as well as different steam data, sizes and types of boilers. Two further facilities, in which the test materials Alloy 625 and Sanicro 28 had already been installed, were also included in the investigation. The duration of service exposure was one operating season. The weld cladding was measured with a thickness gauge before service exposure and at inspection intervals. Disc samples of each test material were also removed from the test panels for metallographic analysis. The results showed significant corrosion of all six weld overlay materials in the boiler with relatively high steam data and highly corrosive fuel. Metal losses were in the range 0.3 - 1.2 mm after one operating season. The 310 stainless steel suffered fairly uniform corrosion, while the nickel-base alloys exhibited localised pitting. Corrosion in the other boilers was much less pronounced, and in many cases no significant reduction in cladding thickness was observed. Chemical analyses of corrosion products and deposits showed large variations in composition, even within small areas, and indicated that the local environment fluctuates widely. Appreciable levels of chloride, alkali and heavy metals were present, and it was concluded that molten salt fluxing is a primary damage mechanism. The large variations in composition mean that more extensive sampling should be carried out to obtain a complete picture of the corrosion processes on water walls. Nevertheless, the results so far indicate that stainless steels of type 310 or Sanicro 28 can compete with the more expensive Ni-base alloys. Service exposure should be continued for another one or two operating seasons in order rank all the materials in relation to the different types of boilers and to draw more general conclusions

    2011-12-01

    Full Text Available Cet article dresse le bilan des études de genre menées en Espagne et revient sur les concepts-clé ayant orienté la recherche dans ce domaine. Il montre la relation entre l´évolution du féminisme théorique et l´apparition progressive d´un vocabulaire qui défini les femmes comme des sujets politiques. Si les relations de pouvoir sont l´épicentre des catégories structurant l´analyse historique, la violence, les demandes sociales et le matérialisme traversent la société civile et s’inscrivent dans l´agenda des États. L´avenir, néanmoins, s’accompagne de nouveaux défis et dialogues interculturels qui, sans aucun doute, transformeront le discours des femmes et le langage des genres au XXIe siècle.In these lines there is an account of gender studies in Spain and the key concepts on which this research has pivoted. The aim of this article is to show the relationship between the evolution of feminist theory and the gradual emergence of a vocabulary that explain women as political subjects. If power relationships are the epicenter of the categories of historical analysis, violence, social demands and maternalism are on the street and the agendas of state. But the future brings new challenges and intercultural dialogue, no doubt, will expand or transform the discourse of women and gender language in the XXI century.En estas líneas se hace balance de los estudios de género en España, así como los conceptos clave sobre los que la ha pivotado la investigación.

  12. L’impossible « dernier mot ». La maquette du journal : un outil partagé

    Full Text Available La maquette du journal occupe une place particulière dans le continuum de fabrication de l’information. Elle est située à l’interface de la matérialité du journal entre la salle de rédaction et le secteur du prépresse. Les discours et les prérogatives dont elle est capable de se charger font qu’elle porte en elle un potentiel stratégique organisationnel important. La maquette du journal demeure pourtant un acteur méconnu de la sociologie des médias. Cette étude, qui se situe au carrefour de la sociologie interactionniste et de la théorie de l’acteur-réseau, propose de donner toute sa place à la maquette et à ceux qui la construisent et l’utilisent au quotidien dans le journal. Nous montrons que c’est entre deux acteurs particuliers et leurs manières différenciées d’être à ce qu’ils font que la maquette est susceptible de révéler tout son potentiel : les journalistes secrétaires de rédaction (SR et les ouvriers typographes. Nous tentons tout d’abord de saisir pourquoi ces trois acteurs (maquette, SR et typographes sont demeurés invisibles au sein du journal. Il s’agit donc de repenser leur place et leur rôle, de les révéler au prisme d’une grille d’observation renouvelée, agrandie. Nous sommes ensuite en mesure d’observer la manière dont ces trois acteurs peuvent interagir, peuvent s’attacher au sein du processus de fabrication de l’information. Pour cela, nous développons trois exemples issus d’un travail de terrain au sein d’un titre de presse quotidienne régionale (PQR. Il s’agit en fait de comprendre les manières dont les journalistes SR et les ouvriers typographes sont plus ou moins parvenus — selon les époques retenues, et de manière non linéaire — à se saisir de l’objet maquette, pour faire ce qui est à faire — le journal — au plus près de la manière dont ils souhaitent le faire. The newspaper layout has a special place in the continuum of news production. It is located at the interface between conception and materiality - between newsroom and pre-press area. The discourses and prerogatives for which in can be responsible confer it an important strategic organizational potential. And yet, the newspaper layout remains a little-understood element in the sociology of media. This study, which finds itself at the intersection of interactionist sociology and actor-network theory, is dedicated to the layout and those who construct it and use it daily in the newspaper. We show that it is through their differentiated roles that two agents in particular make it possible for the layout to realize its full potential: editorial secretaries (SR and typographers. We try first to understand why these three actors (the layout, SR and typographers have remained invisible within the newspaper. It is therefore a question of rethinking their place and role – of renewing and widening the observation matrix. We can then observe how these three actors interact at the core of the news-production process. To do this, we develop three examples from fieldwork carried out in a regional daily newspaper. In fact, it is an attempt to understand the ways in which copy-editing journalists and typographers were more or less able (depending on the eras selected; and in a non-linear way to seize control of the layout and create what was necessary – the newspaper – as closely as possible to their vision of how it should be done. A diagramação do jornal ocupa um lugar particular no continuum da produção da informação. Ela está situada na interface da materialidade do jornal, entre a redação e o setor de pré-impressão. Os discursos e as prerrogativas sob a responsabilidade da diagramação garantem a ela um importante potencial estratégico e organizacional. Contudo, a diagramação do jornal continua sendo um ator desconhecido do ponto de vista da sociologia da mídia. Este estudo, que se situa na interseção entre a sociologia interacionista e a teoria do ator-rede, dedica-se ao estudo da diagramação e dos atores que trabalham na construção e na utilização dessa prática no cotidiano do jornal. Destacamos dois atores em particular: os copidesques (em francês: secrétaires de rédaction, SR e os gráficos. Eles possuem maneiras distintas de ser, o que permite à diagramação revelar todo o seu potencial. Num primeiro momento, buscamos entender em que sentido os três atores (diagramação, copidesques e gráficos permanecem invisíveis no interior do jornal. Trata-se, portanto, de repensar o seu lugar e o seu papel, de revelá-los ao prisma de uma grelha de observação renovada e ampliada. Em seguida, observamos a forma como esses três atores podem interagir, podem se agrupar em torno do processo de produção da informação. Para isso, desenvolvemos três exemplos oriundos de uma pesquisa de campo realizada no interior de um veículo da impressa regional na França. Trata-se de compreender o modo como os copidesques e os gráficos se utilizam – em momentos específicos e de uma forma não linear – do projeto gráfico para darem conta de suas obrigações – a produção do jornal –, mas buscando aproximar esse processo da forma como eles acreditam que isso deve ser feito.

    2012-09-01

    Full Text Available In this paper, elaborating on Daneš’ idea of the “three-levels approach” to syntax, we advance the hypothesis that the global information structure of an utterance is the result of a synergistic action of semantic, syntactic and Theme-Rheme structures. In particular, we focus on the structural and formal factors of the functional sentence perspective, hence distinguishing between Theme-Rheme on the one hand and Given-New and Presupposition-Assertion on the other. The latter notions, though correlated to that of Theme-Rheme, are distinct from it. We apply this theoretical framework to the German language aiming at showing how, in this language, the linguistic means realizing the actual articulation in Theme and Rheme (particularly, word order and intonation together with syntax and semantics determine the structure of an utterance and make it a ‘communication unit’ apt to be placed within specific verbal exchange contexts.

  18. Analysis of transient plasmonic interactions using an MOT-PMCHWT integral equation solver

    KAUST Repository

    Uysal, Ismail Enes

    2014-07-01

    Device design involving metals and dielectrics at nano-scales and optical frequencies calls for simulation tools capable of analyzing plasmonic interactions. To this end finite difference time domain (FDTD) and finite element methods have been used extensively. Since these methods require volumetric meshes, the discretization size should be very small to accurately resolve fast-decaying fields in the vicinity of metal/dielectric interfaces. This can be avoided using integral equation (IE) techniques that discretize only on the interfaces. Additionally, IE solvers implicitly enforce the radiation condition and consequently do not need (approximate) absorbing boundary conditions. Despite these advantages, IE solvers, especially in time domain, have not been used for analyzing plasmonic interactions.

It evaluated the effect of contact on Sitophilus zeamais and by ingestion in Blattella germanica. To irradiation was used an experimental irradiator of Cobalt-60, type Gammacell 220. The essential oils were submitted increasing doses of gamma radiation: 2.5; 5.0; 7.5 and 10.0 kGy. The bioassay with B. germanica demonstrated efficiency between 22.0 e 30.0% and between 30.0 and 42.0%, respectively, to irradiated essential oils of E. citriodora and E. globulus and they demonstrated too repellency to the nymphs. The gamma radiation used promoted changes in essential oils of E. citriodora e E. globulus that they began to show efficiency on B. germanica nymphs besides a significant reduction of repellency. Essential oils of Pinus sp., A. indica, C. sempervirens and J. communis did not display efficiency. The essential oils of C. nardus, and C. citratus had low efficiency. The gamma radiation increased the efficiency of ethanolic extract of D. Pinnata with dose of 7.5 kGy, showing 48.0% of efficiency on B. germanica nymphs. The gamma radiation showed adverse effect on the aqueous extract of R. Graveolens, decreasing its efficiency of 20.0% to 2.0% in doses of 2.5; 7.5 and 10.0 kGy and 4,0% In dose of 5.0 kGy. The bioassay with S. zeamais demonstrated that irradiated essential oils of E. citriodora, E. globulus e Pinus sp. with dose of 5.0 kGy presented 100.0; 92.0 and 100.0% of efficiency, respectively.

    Österlund, Mia

    2011-03-01

    Full Text Available This article considers the conditions and possibilities of writing a methodologically innovative glocal history of post-war Swedish-language children’s literature in Finland. Since previous studies of this literature are, as of today, fragmented and scattered in various publications, a comprehensive and more nuanced picture of the time period is sorely needed. Yet, how is such a project to be carried out in light of recent revisionist debates on the possibility of writing national literary histories? The article proposes that the answer lies in applying transnational, intersectional and visual perspectives onto the material. A working hypothesis is that parallel representations of Finno-Swedishnesses, influenced by shifting notions of the child and childhood and by the liminality of Finno-Swedish culture, permeate the literature under study. Transnational and intersectional perspectives can, therefore, shed new light on representations of ideological and societal tendencies, such as power negotiations between generations, multilingualism, gender, and class distinctions. A fully integrated visual perspective acknowledging paratextual and material aspects of children’s literature would further deepen the discussion. Acknowledging transnational tendencies, an intersectional and visual national children’s literature history could thus interrogate established “truths” about Finno-Swedish children’s literature and thereby open up new ways of viewing this liminal literature.

    The last few years, production of alternative fuels has grown significantly. The driving force can be primarily attributed to a growing interest in protecting the climate and the policy initiatives resulting from this, rising oil prices and industrial and agricultural interests. However, the debate has increasingly begun to question the usefulness and impact of a continued expansion of biofuels. The report provides an overview of our knowledge with respect to climate benefits, and economic potential for the 1st generation of ethanol and biodiesel, 2nd generation biofuels and electricity via e.g. plug-in hybrids. The report also provides various scenarios of how Sweden can meet the adopted EU directive on renewable energy in the transport sector to 2020. The substitution of fuels in the transport sector has only just begun. Driving forces, including those visible in the criteria of the EU Directive, however, will aim for more climate-effective fuels based on waste and forest raw material compared to today's efforts. Effective grain based fuels can still retain a relatively large niche even in the longer term, since the investment is justified by several reasons, including agricultural policy. Electric vehicles are expected to be launched in the not too distant future. But it will take a long time before electricity consumption via eg plug-in hybrids is visible in the statistics. Increased demands on energy efficiency can drive a trend towards more expensive vehicles and also to change forms of ownership and use of vehicles, including increased car pooling

    Full Text Available This paper is based on a bachelor thesis which had the aim of showing the implementation of folk motifs in other types of dances apart from the folk dance styles, namely in the professional dance form of the latest demonstration of movement - in contemporary dance and physical theatre. It does not stress the issue of stylized dance folklore and its interpretation on the stage; it works with the folk motif as with a symbol depending on the particular plot of the performance. This means that the folk motif has a functional meaning, thus supplementing the nonverbal communication. This article deals with representing folklore from an interdisciplinary point of view: it uses knowledge from ethnology in identification and analysis of folk demonstrations in contemporary dance and physical theatre, and it also uses knowledge from choreology within the analysis and the structure of the particular motifs and levels of stylization. In order to achieve our aim, we have chosen the structural method and formal analysis; we have also created graphic models. We consider the key part of the paper to be the clarification of the graphic models presented, which connect the issues of occultism and initiatory rituals with issues of contemporary and folk dance. Thanks to the connections found between movement production and imitative occultism, both the principles of occultism and the ways it affects objects can be identified in the creation of movement. As a result, inferences can be drawn based on the performance analysis. This article is based on empirical knowledge: two professional dance groups and their performances serve as the example. They show the meaningful form from the content and visual points of view. When speaking about folklorism, we consider this topic to be a new one because the basics of the research concern folk dance presented in a different dance style and processed in other than its “own stylized” environment.

    2015-01-01

    Full Text Available This paper concentrates on the evaluation of reliability measures of a computer system of two-identical units having independent failure of h/w and s/w components. Initially one unit is operative and the other is kept as spare in cold standby. There is a single server visiting the system immediately whenever needed. The server conducts preventive maintenance of the unit after a maximum operation time. If server is unable to repair the h/w components in maximum repair time, then components in the unit are replaced immediately by new one. However, only replacement of the s/w components has been made at their failure. The priority is given to the preventive maintenance over repair activities of the h/w. The time to failure of the components follows negative exponential distribution whereas the distribution of preventive maintenance, repair and replacement time are taken as arbitrary. The expressions for some important reliability measures of system effectiveness have been derived using semi-Markov process and regenerative point technique. The graphical behavior of the results has also been shown for a particular case.

  17. Observation of spin-polarized bands and domain-dependent Fermi arcs in polar Weyl semimetal MoT e2

    We investigate the surface electronic structures of polar 1 T'-MoT e2 , the Weyl semimetal candidate realized through the nonpolar-polar structural phase transition, by utilizing the laser angle-resolved photoemission spectroscopy combined with first-principles calculations. Two kinds of domains with different surface band dispersions are observed from a single-crystalline sample. The spin-resolved measurements further reveal that the spin polarizations of the surface and the bulk-derived states show the different domain dependences, indicating the opposite bulk polarity. For both domains, some segmentlike band features resembling the Fermi arcs are clearly observed. The patterns of the arcs present the marked contrast between the two domains, respectively agreeing well with the slab calculation of (0 0 1) and (0 0 -1) surfaces. The present result strongly suggests that the Fermi arc connects the identical pair of Weyl nodes on one side of the polar crystal surface, whereas it connects between the different pairs of Weyl nodes on the other side.

    The study of the Tip of the Tongue phenomenon (TOT) provides valuable clues and insights concerning the organisation of the mental lexicon (meaning, number of syllables, relation with other words, etc.). This paper describes a tool based on psycho-linguistic observations concerning the TOT phenomenon. We've built it to enable a speaker/writer to find the word he is looking for, word he may know, but which he is unable to access in time. We try to simulate the TOT phenomenon by creating a situation where the system knows the target word, yet is unable to access it. In order to find the target word we make use of the paradigmatic and syntagmatic associations stored in the linguistic databases. Our experiment allows the following conclusion: a tool like SVETLAN, capable to structure (automatically) a dictionary by domains can be used sucessfully to help the speaker/writer to find the word he is looking for, if it is combined with a database rich in terms of paradigmatic links like EuroWordNet.

  1. To use the full potential of electric metering - a step towards a more energy effective Sweden; Att utnyttja elmaetarnas potential - ett steg mot ett energieffektivare Sverige

    Energy Technology Data Exchange (ETDEWEB)

    In line with national and international targets, the electricity market will be characterized by increased use of renewable energy, an increased share of electric plug-in vehicles, engaged consumers, who are conscious of their electricity use and produce their own electricity, and by smarter electricity distribution systems. This will put higher demands for stricter requirements on the available transmission capacity and on the security of supply. Elaborate metering systems is one condition for meeting the challenges facing the electricity market. Electricity metering is also relevant for a range of applications such as remote reading, management of customer relations, demand management and value added services. Utilizing meter data to provide feedback enables use of the electricity metering systems in order to obtain electricity conservation. As of July 2009 the Swedish electricity distributors are required to read and report the electricity use on a monthly basis for all customers with a safety fuse of up to 63 amps. Remote electricity reading is the main function in the current system, which means that the distribution system operator (DSO) is provided with metering data without the need for manual reading and that the customers are charged on a monthly basis for their actual electricity use (rather than an estimate). One reason for the introduction of monthly billing, based on actual electricity use, was to visualize the electricity use to the households. For the electricity use to become visual and controllable, it is important that customers receive feedback on their electricity use. The introduction of monthly billing implied an improvement of the feedback, but it can be further improved in order to allow greater savings. Improved feedback can be given by synthesizing high-resolution data to information presented in new ways, for example by means of in-home-displays, and web-based interfaces combined with counselling. Research shows that the electricity consumption can be reduced by up to 15 percent by using feedback. As a safeguard against future legislative demands over 50 percent of the household have been provided with meters that can handle hourly metering. However, hourly metering is not used to a great extent due to a lack of incentives for the distributors to make use of the hourly metering values. Furthermore not all meters have communication infrastructure that can manage daily collection of values. By changing the current demand of daily collection of values it is possible to employ hourly metering for 74 percent of the households. In addition, propositions of introducing a new metering standard speaks against further investments in the existing metering systems. The metering systems' ability to reflect the short term electricity balance for the consumers is a prerequisite for normal price mechanisms to maintain the security of supply. For that reason, there is a need of metering values with higher resolution in order to indirectly, i.e. by more dynamic tariffs, influence the customer to use less electricity during high load periods. By using hourly metering to the extent made possible with the existing metering systems, this type of service could be offered to a part of the Swedish households. Currently, only the electricity distributors have access to the metering values in the metering systems. This situation limits the business potential that arises from the development of metering services. The business potential is also limited by the fact that the possible savings from electricity conservation are small. Innovation and investments in metering services world be promoted by making metering data accessible to more stakeholders. The development would also be positively affected by higher electricity prices, institutional means of control that promote energy services, and an increasing awareness among consumers. A number of functions that will be important to address the changes facing the electricity market are often referred to in connection to smart grids; the charging of plug-in vehicles, virtual power plants, distributed generation and management of the electricity net. The development of electricity meters, and associated systems is an important prerequisite in the quest towards a smarter grid. These functions are not fully applicable with the existing electricity metering system. Enabling of these functions would probably require major investments in the network, more advanced meters and more advanced communications infrastructure

    Ukraine is one of the largest industrial countries in Europe. The country has Europe's highest CO{sub 2} emissions in relation to gross national product, and a further sharp increase in the emissions can be expected towards 2030. The main reason for this is a major planned shift from natural gas to coal in both industry and energy sector. This will increase CO{sub 2} emissions by about 70 million tons per year. Energy efficiency and transition to renewable energy is therefore strongly required to reduce emissions this dramatic increase. (AG)

    Insecticidal effects of different doses of the dust and methanol extracts ofGarcinia kolae on Callosobruchus maculatus and Sitophilus zeamais were tested. The dust had no significant effect on the two insects; none of them died even at 3 d after treatment. The methanol extracts, however, had rapid lethal effects on both C. maculatus and S. zeamais. The mortality of C.maculatus by the lowest concentration of methanol extracts ranged from 95%~100% whereas in S. zeamais, the mortality ranged from 87.5%~100% and 70% ~100% in concentrations of 1 g extract+3 ml methanol and 1 g extract+5 ml methanol, respectively,from 24 to 48 h. The least concentration of 1 g extract+15 ml methanol had no significant lethal effect on Sitophilus zeamais.

Il a été convenu d’appeler l’été 1990 au Québec la crise d’Oka, ou l’été des Indiens. Très fortement médiatisée, la crise d’Oka deviendra dans les années qui suivent le symbole des revendications autochtones, ainsi que celui de l’incompréhension régissant leurs relations avec l’État. Brutal, l’été des Indiens échauffe et marque les esprits de chacun et laisse des séquelles profondes dans les deux communautés impliquées. Même après la fin de la crise, le sujet est traité sporadiquement dans les médias. Le spectre d’Oka plane au-dessus de nos têtes, menaçant, et les médias ne se privent pas de le rappeler à la moindre occasion. La mémoire de la crise est donc vive, et peu suffit à la population pour se rappeler les douloureux événements de l’été 1990, qui font référence à l’incompréhension, à l’échec.

  19. Field test of low-pressure turbine blading with improved resistance against corrosion fatigue; Faeltprovning av laagtrycksturbinskovlar med foerbaettrad haerdighet mot korrosionsutmattning

    Energy Technology Data Exchange (ETDEWEB)

    Tavast, Jueri [Alstom Power Sweden AB, Finspong (Sweden)

    2003-07-01

    Corrosion fatigue of turbine blades in low-pressure turbines is one of the most common reasons for reduced availability and reliability in fossil fueled as well as in nuclear steam turbine plants. The problem is almost exclusively localized to the area where the first condensation takes place. There is therefore a need for materials with improved resistance towards corrosion fatigue for blades in stages in the transition zone between dry and wet steam. The phase hardening stainless steel 15/5 PH is such an alternative material. This material has shown a significantly better resistance towards corrosion and corrosion fatigue in laboratory tests. The lack of field experience of this material in real plants has, however, made it difficult to introduce this relatively new and untried material. Corrosion fatigue has caused problems in the some of the nuclear units in Forsmark. Forsmark 2 was therefore regarded as a suitable plant for a field test. The result of the field test is applicable to conventional as well as to nuclear units. A total of 10 blades of 15/5 PH were installed to replace blades of conventional blade material in a stage with a ar and 40 previous history of corrosion fatigue. The field test was interrupted after 5 years and 40,000 hours of operation. The main objective of the field test was to demonstrate that blades of 15/5 PH could be successfully machined, tested, installed and of course also used in a real plant. The field test also enabled a comparison of the corrosion resistance of the two alloys. It should be underlined that demonstration of the improved resistance towards corrosion fatigue has not been an objective during this field test as this has already been evidenced by various laboratory investigations. The properties of the parent material as well as of the finished blades were controlled and documented as carefully as possible before the field test to enable evaluation of the field test. The condition of the 10 blades of 15/5 PH included in the field test was compared with the condition of 10 randomly chosen blades of conventional material from the same stage. The field test was completed without problems. Nondestructive testing did not indicate any new defects after 5 years of operation. There is also less corrosion attack in the blades of 15/5 PH than in the blades of conventional material. The conclusion of the field test is that blades of 15/5 PH can be recommended for turbine stages in the transition zone between dry and wet steam, at least for plants where corrosion fatigue has been a problem or is expected to become a problem. The cost for a finished blade of 15/5 PH is approximately 20% higher than the cost for a blade of conventional material for a conventional steam turbine in the 50 MW range.

    Abstract This essay begins with a presentation of the complex set of problems which relate to the interaction between freedom of speech and the ban against discrimination based on a person's race, the colour of their skin or ethnic origin, confession of faith or sexual preference (BrB 16:8, incitement to racial hatred). Can conflicts arise between freedom of speech and the ban against discrimination? To shed light on this question, we have chosen to look at the issue from a new perspective. T...

    The Kyoto Protocol of December 1997 opens up the possibility that forestal measures can be used to meet parts of the commitments of the industrialized countries to achieve a net reduction of emission of climate gases. The present report summarizes the issues involved in forestal measures that will mitigate global climate changes. The emphasis is on forestal measures in the climate negotiations and technical carbon binding potential. There is also a brief review of economic, environmental and social aspects. The next decades will be crucial to the many of the world`s forests. The forests contain a large part of the biological diversity. Above all this is true of tropical forests. But untouched areas in tempered and boreal areas are also experiencing various types of threats, including the effects of a possible global heating. It is a main conclusion that, in spite of many complex challenges, climate measures in the forests may play a constructive role both in counteracting global climate changes and in improving the management of the world`s forest resources. 89 refs., 3 figs., 7 tabs.

    Full Text Available Biogeochemical ocean circulation models used to investigate the role of plankton ecosystems in global change rely on adjustable parameters to capture the dominant biogeochemical dynamics of a complex biological system. In principle, optimal parameter values can be estimated by fitting models to observational data, including satellite ocean colour products such as chlorophyll that achieve good spatial and temporal coverage of the surface ocean. However, comprehensive parametric analyses require large ensemble experiments that are computationally infeasible with global 3-D simulations. Site-based simulations provide an efficient alternative but can only be used to make reliable inferences about global model performance if robust quantitative descriptions of their relationships with the corresponding 3-D simulations can be established. The feasibility of establishing such a relationship is investigated for an intermediate complexity biogeochemistry model (MEDUSA coupled with a widely used global ocean model (NEMO. A site-based mechanistic emulator is constructed for surface chlorophyll output from this target model as a function of model parameters. The emulator comprises an array of 1-D simulators and a statistical quantification of the uncertainty in their predictions. The unknown parameter-dependent biogeochemical environment, in terms of initial tracer concentrations and lateral flux information required by the simulators, is a significant source of uncertainty. It is approximated by a mean environment derived from a small ensemble of 3-D simulations representing variability of the target model behaviour over the parameter space of interest. The performance of two alternative uncertainty quantification schemes is examined: a direct method based on comparisons between simulator output and a sample of known target model "truths" and an indirect method that is only partially reliant on knowledge of the target model output. In general, chlorophyll records at a representative array of oceanic sites are well reproduced. The use of lateral flux information reduces the 1-D simulator error considerably, consistent with a major influence of advection at some sites. Emulator robustness is assessed by comparing actual error distributions with those predicted. With the direct uncertainty quantification scheme, the emulator is reasonably robust over all sites. The indirect uncertainty quantification scheme is less reliable at some sites but scope for improving its performance is identified. The results demonstrate the strong potential of the emulation approach to improve the effectiveness of site-based methods. This represents important progress towards establishing a robust site-based capability that will allow comprehensive parametric analyses to be achieved for improving global models and quantifying uncertainty in their predictions.

  5. A green thread: five strategic principles that lead us to a sustainable energy system towards 2050; En groenn traad: fem strategiske prinsipper som leder oss til et baerekraftig energisystem mot 2050

    The overall goal for the world is to limit global warming to two degrees in 2050, which requires an emission level of maximum two tonnes per capita in 2050, assuming we start cutting emissions in time. The climate challenge can only be solved through a comprehensive adjustment of the energy system and a well-functioning energy system is required to achieve the climate targets. This also applies for Norway, as two-thirds of our greenhouse gas emissions are linked to energy use in the petroleum, industry, transport and heating sectors. At the same time, secure access to energy is a precondition for financial development, both in the least developed parts of the world and the western world. In the last 100 years, the development in the Norwegian economy has been very closely connected to the energy sector, first through development of industry based on utilisation of the hydropower resources, and subsequently through recovery of oil and gas on the Norwegian shelf. At the same time, the development within ICT has facilitated an increasingly service-based economy where electricity is a crucial input factor. Through electrification of society, the power system has become an increasingly important critical infrastructure on a par with telecommunications, water supply, the transport system, health services, etc. - perhaps the most important we have considering all the processes in society that directly depend on stabile access to electricity. If we are to achieve the two-degree target in 2050, we must immediately start cutting emissions globally to prevent the accumulated emissions from becoming too large. It will be cost efficient, in a global perspective, to start now. To a large degree, this also applies for Norway. Purchasing quotas can be used to a certain degree in the short term, but in the long term we must also cut the physical emissions here at home. The reason behind this is that we must have implemented most of the emission-reducing measures on a global basis by 2050, also in industrialised countries. Then there will be no surplus of cheap quotas and we must expect much higher quota prices than today. It we wait too long, there will also be very great implementation challenges when major emissions cuts are made in a short period, and Norwegian businesses will become less competitive and have less business opportunities due to inadequate adaptation at home. In this perspective, purchase of quotas is a payment extension and not a permanent solution. Norwegian climate policy up towards 2020, such as the Storting's (Norwegian Parliament's) climate agreement from 2008, is only a first step that must be followed up with further cuts at a steady pace towards 2050.There are many political and strategic challenges associated with the climate and energy policy. Adapting the energy systems will require extensive measures over a long period of time. However, we are not good at making decisions that are necessary in the long term, but uncomfortable in the short term. It is difficult to see consequences of decisions across sectors. This leads to policies being characterised by an inability to see the big picture. It is difficult to imagine what will happen towards 2050 because the world is dynamic and innovative. Inadequate strategies not only entail inadequate climate target achievements, but also a decline in value creation. The adaptation in Norway and internationally creates new business opportunities for energy companies, industrial companies and service suppliers both in the short and long term. It is therefore crucial for both the climate and our economic development that we manage to create good strategies within energy and climate.A green thread is a tool for long-term strategic choices that unite climate, energy and value creation. A green thread is based on two constants: The two-degree target must be achieved in 2050. This entails a requirement for a maximum of two tonnes of emissions per capita in the world and Norway.We must have a well-functioning energy system. A well-functioning energy system is characterised by always providing enough energy and capacity, utilising resources efficiently, harming the environment as little as possible and ensuring a relatively balanced development between production and consumption of energy and associated infrastructure.Based on these constants, we have formulated five strategic principles for development of the energy system. Action rule for climate: Emissions must be cut to achieve the two-tonne target in 2050, and not exceed the total permitted emissions towards 2050.Co2-neutral energy carriers: End users must have Co2-neutral energy carriers and Co2 must be removed from the production stage.Robust energy system: We must have a very high delivery reliability and very low vulnerability as regards interruptions to the access of energy.Balanced development: Production, consumption and infrastructure for transport of energy must be developed concurrently. Efficient resource utilisation: We must utilise the resources in the energy system as efficiently as possible. This entails minimising costs and environmental impact.Together, these five principles form a comprehensive framework for the development of the energy system within a framework of climate and value creation considerations. The principles fulfil several functions:Principle 1 - the action rule for greenhouse gas emissions is based on a corresponding mechanism for the revenue from the oil activities, but with one important difference: The rule is not based on a constant expected real return (or a flat development path), but a defined path for greenhouse gas emissions which decreases from the current level to a maximum of two tonnes per capita in 2050. Two tonnes is the maximum level in 2050 that is consistent with a global warming of two degrees, given the expected world population in 2050. It is not unlikely that the level must be even lower in Norway and the industrialised countries if the developing countries are to experience growth during the same period. We do not take a specific stance on the exact level for Norway's part - but it must be reduced to a maximum of two tonnes per capita in 2050. Around the two-tonne path the annual emissions can vary as long as the final target is achieved. In addition, the action rule entails a requirement for the total emissions towards 2050. As greenhouse gases remain in the atmosphere for a long time (depending on the type of greenhouse gas), the level in 2050 is not the only factor in achieving the target of a global warming maximum of two degrees. The action rule therefore also implies that that higher emissions than the linear two-tonne path in a period must be met with corresponding lower emissions than the two-tonne path in subsequent periods, so the restrictions on the total emissions over time are complied with.The action rule for climate ensures a gradual phasing out of the greenhouse gas emissions in accordance with a global two-tonne path, but also provides flexibility to use quota purchases to avoid unfortunate consequences for the global climate and Norwegian competitiveness due to carbon leaks. It also provides predictability regarding the value of emission-reducing measures for companies, individuals and authorities and thus contributes to a more efficient implementation of emission reductions in Norway.In a 2050 perspective, it is not a question of whether to cut emissions nationally, but how much to cut and when. There will not be a large global surplus of cheap Co2 quotas in 2050. By then, most measures must have been implemented if we are to achieve the two-degree target. If we start today, we need to cut a minimum of 40 million tonnes in 40 years in Norway, i.e. at least one million tonnes per year on average.Principle 2 - adaptation to Co2-neutral energy carriers because we are not familiar with development of technology that can provide small-scale Co2 handling for end users. Electricity will be the dominant energy carrier in the future because electricity can be produced and transported to the users in large volumes and over great distances on a completely different magnitude than the other Co2-neutral energy carriers. The requirement for a well-functioning electricity system will therefore be key in the development of the energy system towards 2050.Principle 3 - robustness is the energy system's ability to deliver energy and output instantaneously or over a short period of time (for example a winter season). In this context, robustness is closely related to the term security of supply, but is more limited in time. Security of supply also covers the long-term access to energy, cf. the principle regarding balanced development below. The principle generally applies nationally and locally, but can also be used in a larger geographic region such as Northwestern Europe.Principle 4 - balanced development refers to the fundamental relationship between production and consumption of energy over a longer period, as a minimum between seasons but also over several years. The principle thus deals with the physical access to energy relative to the demand in the long term, and differs from robustness through the time perspective. The principle can be used both nationally and for a larger region that is physically connected through the energy system (such as Northwestern Europe). A key element to achieve balanced development is well-functioning markets.Principle 5 - effective resource utilisation is a prerequisite for achieving targets associated with climate, energy and value creation at the same time. Effective resource utilisation entails the overall costs of various measures in the energy system (and measures in the energy system in general), both specific measures that contribute to emission reductions and general measures. The lowest possible costs free up resources for value creation in other sectors in the economy, both in the form of capital and labour, and minimize interventions in the environment.The five strategic principles are tools for a structured dialogue regarding climate, energy and value creation in various arenas. The principles can be used as a basis to formulate specific tests for various measures and instruments within climate and energy in practice. Measures and instruments that do not fulfill the tests must either be rejected or adjusted.(Author)

    Fusobacterium nucleatum is present in colon cancers where it was shown to generate a proinflammatory microenvironment that supports colorectal neoplasia progression. Remarkably, alongside with proinflammatory stimulation, fusobacteria also inhibit cytotoxicity of immune cells. Thus, it appears as if tumors exploit fusobacteria to generate a favorable proinflammatory and anti-cytotoxic microenvironment.

    Full Text Available The Norwegian author Alf Prøysen made use of a number of different media technologies in the production and distribution of his literature for children. But more than that, in some of these stories he also reflected upon modern technology in general. This is the case in his collection of short stories for children, Da jeg var liten (When I was a Child. Here Prøysen emphasises how child protagonists perceive modern technology such as cars, airplanes, and tractors, in a rural setting in the 1920s, with both fascination and anxiety. Still, at the end of the story the protagonist, Alf, exceeds both of these responses when he reflects on the “real” meaning of technology, and comes to the conclusion that nature can create miracles and do things that modern technology cannot. The article discusses how Prøysen’s presentation of modern technologies in Da jeg var liten can be regarded as literary techno-critique, arguing that the protagonist’s change of perception can be interpreted as a shift from what Martin Heidegger more in general has called ”calculative thinking” to that of ”meditative thinking”.

    This study has as its point of departure that large reserves of energy and minerals are deposited in the Arctic. There is uncertainty on how large these reserves are and if extraction of them is technically and economically feasible. As the Arctic gradually becomes more accessible as the melting of the sea-ice in the Arctic Ocean progresses, the region becomes more open to human activities than ever before. The energy issue in the Arctic develops against the background of the region's increasing geostrategic importance. Russia shows no hesitation, Norway also put considerable resources into energy extraction in the Arctic. Environ-mental protection is a more prominent issue in Norway, Canada and the USA than in Russia. In addition to the energy issue, other factors in the Arctic are also changing. Shipping, climate change, military strategy, nuclear weapons, overlapping territorial claims, developments in international security and national policies and efforts, are all parts of a development that does not easily let itself be described and analysed. The different factors under change develop according to their own character and inner logic and how they interact will be hard to foresee. Uncertainties of future developments in the Arctic therefore remain. The Arctic will become more clearly linked into developments in the rest of the world than hitherto. The region will no longer be exclusively an issue for the states in the region. The interest in the Arctic is on the increase, not only from the Arctic states, but also from external state actors in Europe and Asia, as well as multilateral organisations such as the European Union and NATO

    Requirements on PSA for risk informed applications are expressed in different international documents. The ASME PRA standard published in spring 2002 is one such document, PSA requirements are also expressed in the European Utility Requirements (EUR) for new reactors. The Swedish PSA requirements are provided in the Swedish regulators (SKI) statutes SKIFS 2004:1. SKI also has a review handbook for PSA activities (SKI report 2003:48). The review handbook is a support during review of the utilities PSA activities and the PSAs themselves. The review handbook expresses SKIs expectations by providing so called important aspects for both the PSA work and the PSAs, A comparison of SKIFS requirements and the important aspects in the Review handbook, on one side, and the requirements on PSA in EUR and ASME on the other side, is presented. The comparison shows a large difference in the level of detail in the different documents, where ASME is most detailed and specific. This is expected since the SKI review handbook not is a 'PSA guide' in the same way as the ASME PRA standard. A direct comparison of the ASME PRA standard requirements with the important aspects in the review handbook cannot answer the question which ASME capacity level that is achieved by a PSA meeting all important aspects. The conclusion is that it is not likely to achieve capacity level 2 and 3, since very few ASME level 3 attributes are explicitly expressed as important aspects, though many are expressed in general terms. The review handbook important aspects that are most similar to the ASME capacity level 1 attributes are initiating events, sequence analysis, and system analysis while less similarity is found for analysis of operator actions data analysis, quantification and containment analysis (level 2). Less similarity is found for capacity level 2 and 3. However, the number of additional ASME attributes on capacity level 2 and 3 are few. There are also important aspects in the review handbook that not are covered by the ASME attributes. These means that insights from the review handbook can further enhance the ASME PRA standard. The compilation of the important aspects in the review handbook, the ASME PRA standard attributes and the European Utility Requirements is presented in a structured way that is judged useful for development of SKI requirements, training and as support during PSA review work. An approach to integrate the ASMEs PRA standard in SKI work is: The review handbook is used as a check list for 'good' PSA work organisation; ASME PRA standard is used as a check list for how the PSA is performed, since this is expressed as being outside the scope of the review handbook. A next step in this kind of work would be to compare an actual recently updated Swedish PSA against the ASME PRA standard requirements.

Around the two-tonne path the annual emissions can vary as long as the final target is achieved. In addition, the action rule entails a requirement for the total emissions towards 2050. As greenhouse gases remain in the atmosphere for a long time (depending on the type of greenhouse gas), the level in 2050 is not the only factor in achieving the target of a global warming maximum of two degrees. The action rule therefore also implies that that higher emissions than the linear two-tonne path in a period must be met with corresponding lower emissions than the two-tonne path in subsequent periods, so the restrictions on the total emissions over time are complied with.The action rule for climate ensures a gradual phasing out of the greenhouse gas emissions in accordance with a global two-tonne path, but also provides flexibility to use quota purchases to avoid unfortunate consequences for the global climate and Norwegian competitiveness due to carbon leaks. It also provides predictability regarding the value of emission-reducing measures for companies, individuals and authorities and thus contributes to a more efficient implementation of emission reductions in Norway.In a 2050 perspective, it is not a question of whether to cut emissions nationally, but how much to cut and when. There will not be a large global surplus of cheap Co2 quotas in 2050. By then, most measures must have been implemented if we are to achieve the two-degree target. If we start today, we need to cut a minimum of 40 million tonnes in 40 years in Norway, i.e. at least one million tonnes per year on average.Principle 2 - adaptation to Co2-neutral energy carriers because we are not familiar with development of technology that can provide small-scale Co2 handling for end users. Electricity will be the dominant energy carrier in the future because electricity can be produced and transported to the users in large volumes and over great distances on a completely different magnitude than the other Co2-neutral energy carriers. The requirement for a well-functioning electricity system will therefore be key in the development of the energy system towards 2050.Principle 3 - robustness is the energy system's ability to deliver energy and output instantaneously or over a short period of time (for example a winter season). In this context, robustness is closely related to the term security of supply, but is more limited in time. Security of supply also covers the long-term access to energy, cf. the principle regarding balanced development below. The principle generally applies nationally and locally, but can also be used in a larger geographic region such as Northwestern Europe.Principle 4 - balanced development refers to the fundamental relationship between production and consumption of energy over a longer period, as a minimum between seasons but also over several years. The principle thus deals with the physical access to energy relative to the demand in the long term, and differs from robustness through the time perspective. The principle can be used both nationally and for a larger region that is physically connected through the energy system (such as Northwestern Europe). A key element to achieve balanced development is well-functioning markets.Principle 5 - effective resource utilisation is a prerequisite for achieving targets associated with climate, energy and value creation at the same time. Effective resource utilisation entails the overall costs of various measures in the energy system (and measures in the energy system in general), both specific measures that contribute to emission reductions and general measures. The lowest possible costs free up resources for value creation in other sectors in the economy, both in the form of capital and labour, and minimize interventions in the environment.The five strategic principles are tools for a structured dialogue regarding climate, energy and value creation in various arenas. The principles can be used as a basis to formulate specific tests for various measures and instruments within climate and energy in practice. Measures and instruments that do not fulfill the tests must either be rejected or adjusted.(Author)

    Molybdenum (Mo) is a trace element essential for living organisms, however no molybdate transporter has been identified in eukaryotes. Here, we report the identification of a molybdate transporter, MOT1, from Arabidopsis thaliana. MOT1 is expressed in both roots and shoots, and the MOT1 protein is localized, in part, to plasma membranes and to vesicles. MOT1 is required for efficient uptake and translocation of molybdate and for normal growth under conditions of limited molybdate supply. Kinetics studies in yeast revealed that the K(m) value of MOT1 for molybdate is approximately 20 nM. Furthermore, Mo uptake by MOT1 in yeast was not affected by coexistent sulfate, and MOT1 did not complement a sulfate transporter-deficient yeast mutant strain. These data confirmed that MOT1 is specific for molybdate and that the high affinity of MOT1 allows plants to obtain scarce Mo from soil.

    We demonstrate launching of laser-cooled Yb atoms in a cold atomic fountain. Atoms in a collimated thermal beam are first cooled and captured in a magneto-optic trap (MOT) operating on the strongly-allowed ${^1S}_0 \\rightarrow {^1P}_1$ transition at 399~nm (blue line). They are then transferred to a MOT on the weakly-allowed ${^1S}_0 \\rightarrow {^3P}_1$ transition at 556~nm (green line). Cold atoms from the green MOT are launched against gravity at a velocity of around 2.5~m/s using a pair of green beams. We trap more than $10^7$ atoms in the blue MOT and transfer up to 70\\% into the green MOT. The temperature for the odd isotope, $^{171}$Yb, is $\\sim$1~mK in the blue MOT, and reduces by a factor of 40 in the green MOT.

    Realizing a molecular magneto-optical trap has been a dream for cold molecular physicists for a long time. However, due to the complex energy levels and the small effective Lande g-factor of the excited states, the traditional magneto-optical trap (MOT) scheme does not work very well for polar molecules. One way to overcome this problem is the switching MOT, which requires very fast switching of both the magnetic field and the laser polarizations. Switching laser polarizations is relatively easy, but fast switching of the magnetic field is experimentally challenging. Here we propose an alternative approach, the microwave-mediated MOT, which requires a slight change of the current experimental setup to solve the problem. We calculate the MOT force and compare it with the traditional MOT and the switching MOT scheme. The results show that we can operate a good MOT with this simple setup.

    Plants represent an important source of molybdenum in the human diet. Recently, MOT1 has been identified as a transport protein responsible for molybdate import in Arabidopsis thaliana L.; however, the function of the homologous protein MOT2 has not been resolved. Interestingly, MOT2-GFP analysis indicated a vacuolar location of this carrier protein. By site directed mutagenesis at the N-terminal end of MOT2, we identified a di-leucine motif that is essential for driving the protein into the vacuolar membrane. Molybdate quantification in isolated vacuoles showed that this organelle serves as an important molybdate store in Arabidopsis cells. When grown on soil, leaves from mot2 T-DNA mutants contained more molybdate, whereas mot2 seeds contained significantly less molybdate than corresponding wild-type (Wt) tissues. Remarkably, MOT2 mRNA accumulates in senescing leaves and mot2 leaves from plants that had finished their life cycle had 15-fold higher molybdate levels than Wt leaves. Reintroduction of the endogenous MOT2 gene led to a Wt molybdate phenotype. Thus, mot2 mutants exhibit impaired inter-organ molybdate allocation. As total concentrations of the molybdenum cofactor (Moco) and its precursor MPT correlates with leaf molybdate levels, we present novel evidence for an adjustment of Moco biosynthesis in response to cellular MoO₄²⁻ levels. We conclude that MOT2 is important for vacuolar molybdate export, an N-terminal di-leucine motif is critical for correct subcellular localisation of MOT2 and activity of this carrier is required for accumulation of molybdate in Arabidopsis seeds. MOT2 is a novel element in inter-organ translocation of an essential metal ion.

    Full Text Available The study was performed in four reindeer-herding districts (Sami villages in northern Sweden. Reindeer herding Sami, born in 1950 or earlier, were interviewed about reindeer foraging behaviour on lichens and mushrooms, especially relating to non-summer grazing habits, and about characteristics of a good winter feeding ground. The informants claimed that lichens are preferably grazed in the wintertime, but that they also may be eaten in the summertime when the weather is cold and humid. Mushrooms were chosen in the autumn months August and September, but according to some informants mushrooms may also be eaten during late autumn (from Oct. when frozen and under the snow. The reindeer herders had different names for lichens, which in general terms describe their appearance and habitat. For mushrooms they only used one Sami name. Ground lichens preferred by reindeer are Cladonia species, while the nitrogen-fixing lichen species such as Nephroma arcticum and Stereocaulon pascale were said not to be preferred by the reindeer. Snow conditions are very important, and the less snow (and the softer it is, the better. Habitats where reindeer herders know from experience that snow conditions tend to be problematic, e.g. in moist and open areas with small trees, are used early in the winter (Oct.–Jan., before too much snow has accumulated. A good winter grazing area should have lichens. It is preferably a dry pine (Pinus sylvestris forest heath with large, old and wide-crowned trees to shelter the ground from snow and thereby ease the cratering by reindeer.

    We have established a caesium double magneto-optical trap (MOT) system for cavity-QED experiment, and demonstrated the continuous transfer of cold caesium atoms from the vapour-cell MOT with a pressure of ~ 1 × 10-6 Pa to the ultra-high-vacuum (UHV) MOT with a pressure of ~ 8 × 10-8 Pa via a focused continuous-wave transfer laser beam. The effect of frequency detuning as well as the intensity of the transfer beam is systematically investigated, which makes the transverse cooling adequate before the atoms leak out of the vapour-cell MOT to reduce divergence of the cold atomic beam. The typical cold atomic flux got from vapour-cell MOT is ~ 2 × 107 atoms/s. About 5 × 106 caesium atoms are recaptured in the UHV MOT.

    This one-year double blind randomized control trial assessed the effects of nightly melatonin, strontium (citrate), vitamin D3 and vitamin K2 (MK7; MSDK) on bone mineral density (BMD) and quality of life (QOL) in postmenopausal osteopenic women (ages 49-75). Compared to placebo, MSDK treatment increased BMD in lumbar spine (4.3%) and left femoral neck (2.2%), with an upward trend for total left hip (p=0.069). MSDK increased serum P1NP levels and reduced bone turnover (CTx:P1NP). Psychometric analyses indicated that mood and sleep quality improved for the MSDK group. MSDK-exposed human mesenchymal stem cells (hMSCs) and human peripheral blood monocytes (hPBMCs) plated in transwells or layered demonstrated increases in osteoblastogenesis, decreases in osteoclastogenesis, increases in OPG (TNFRSF11B) and decreases in RANKL (TNFSF11) levels. In transwell osteoblasts, MSDK increased pERK1/2 (MAPK1/MAPK3) and RUNX2 levels; decreased ERK5 (MAPK7); and did not affect the expression of NFκB (NFKB1) and β1integrin (ITGB1). In layered osteoblasts, MSDK also decreased expression of the metabolic proteins PPARγ (PPARG) and GLUT4 (SLC2A4). In adipose-derived human MSCs, MSDK induced osteoblastogenesis. These findings provide both clinical and mechanistic support for the use of MSDK for the prevention or treatment of osteopenia, osteoporosis or other bone-related diseases. PMID:28130552

    2013-08-01

    An explicit marching on-in-time (MOT) scheme for solving the time-domain magnetic field integral equation (TD-MFIE) is presented. The proposed MOT-TD-MFIE solver uses Rao-Wilton-Glisson basis functions for spatial discretization and a PE(CE)m-type linear multistep method for time marching. Unlike previous explicit MOT-TD-MFIE solvers, the time step size can be chosen as large as that of the implicit MOT-TD-MFIE solvers without adversely affecting accuracy or stability. An algebraic stability analysis demonstrates the stability of the proposed explicit solver; its accuracy and efficiency are established via numerical examples. © 1963-2012 IEEE.

    We present a study on characteristics of a magneto-optical trap (MOT) as an optical lattice. Fluorescence spectra of atoms trapped in a MOT with a passively phase-stabilized beam configuration have been measured by means of the photon-counting heterodyne spectroscopy. We observe a narrow Rayleigh peak and well-resolved Raman sidebands in the fluorescence spectra which clearly show that the MOT itself behaves as a three-dimensional optical lattice. Optical-lattice-like properties of the phase-stabilized MOT such as vibrational frequencies and lineshapes of Rayleigh peak and Raman sidebands are investigated systematically for various trap conditions.

    In previous studies we have reported that a high level of expression of mot-2 protein results in malignant transformation of NIH 3T3 cells as analyzed by anchorage independent growth and nude mice assays [Kaul et al.,Oncogene,17,907-11,1998].Mot-2 was found to interact with tumor suppressor protein p53.The transient overexpression of mot-2 was inhibitory to transcriptional activation function of p53 [Wadhwa et al.,J.Biol.Chem.,273,2958691,1998].We demonstrate here that mot-2 transfected stable clone of NIH 3T3 that showed malignant properties indeed show inactivation of p53 function as assayed by exogenous p53 dependent reporter.The expression level of p53 in response to UV-irradiation was lower in NIH 3T3/mot-2 as compared to NIH 3T3 cells and also exhibited delay in reachingpeak.Furthermore,upon serum starvation p53 was seen to translocate to the nucleus in NIH 3T3,but not in its mot-3 derivative.The data suggests that mot-2 mediated cytoplasmic sequestration and inactivation of p53 may operate,at least in part,for malignant phenotype of NIH 3T3/mot-2 cells.

  8. A Bottom-up Trend in Research of Management of Technology

    2014-12-01

    Full Text Available Management of Technology (MOT is defined as an academic discipline of management that enables organizations to manage their technological fundamentals to create competitive advantage. MOT covers a wide range of contents including administrative strategy, R&D management, manufacturing management, technology transfer, production control, marketing, accounting, finance, business ethics, and others. For each topic, researchers have conducted their MOT research at various levels. However, a practical and pragmatic side of MOT surely affects its research trends. Finding changes of MOT research trends, or the chronological transitions of principal subjects, can help understand the key concepts of current MOT. This paper studied a bottom-up trend in research fields in MOT by applying a text-mining method to the conference proceedings of IAMOT (International Association for Management of Technology. First, focusing on only nouns found several keywords, which more frequently emerge over time in the IAMOT proceedings. Then, expanding the scope into other parts of speech viewed the keywords in a natural context. Finally, it was found that the use of an important keyword has qualitatively and quantitatively extended over time. In conclusion, a bottom-up trend in MOT research was detected and the effects of the social situation on the trend were discussed.Keywords: Management of Technology; Text Mining; Research Trend; Bottom-up Trend; Patent

    A light-pulse atomic interferometry (LPAI) apparatus is provided. The LPAI apparatus comprises a vessel, two sets of magnetic coils configured to magnetically confine an atomic vapor in two respective magneto-optical traps (MOTs) within the vessel when activated, and an optical system configured to irradiate the atomic vapor within the vessel with laser radiation that, when suitably tuned, can launch atoms previously confined in each of the MOTs toward the other MOT. In embodiments, the magnetic coils are configured to produce a magnetic field that is non-zero at the midpoint between the traps. In embodiments, the time-of-flight of the launched atoms from one MOT to the other is 12 ms or less. In embodiments, the MOTs are situated approximately 36 mm apart. In embodiments, the apparatus is configured to activate the magnetic coils according to a particular temporal magnetic field gradient profile.

  12. Photodissociation of trapped Rb$^+_2$ : Implications for hybrid molecular ion-atom trapping

    Jyothi, S; Dutta, Sourav; Allouche, A R; Vexiau, Romain; Dulieu, Olivier; Rangwala, S A

    2016-01-01

    We observe direct photodissociation of trapped $^{85}$Rb$_2^+$ molecular ions in the presence of cooling light for the $^{85}$Rb magneto optical trap (MOT). Vibrationally excited Rb$_{2}^{+}$ ions are created by photoionization of Rb$_{2}$ molecules formed photoassociatively in the rubidium (Rb) MOT and are trapped in a modified spherical Paul trap co-centric with the MOT. The decay rate of the trapped Rb$_{2}^{+}$ ion signal in the presence of the MOT cooling light is measured and agreement with our calculated rates for molecular ion photodissociation is established. The photodissociation mechanism due to the MOT light is expected to be active and therefore universal for all homonuclear diatomic alkali metal molecular ions.

    Full Text Available Introduction: The HIV Modes of Transmission (MOT model estimates the annual fraction of new HIV infections (FNI acquired by different risk groups. It was designed to guide country-specific HIV prevention policies. To determine if the MOT produced context-specific recommendations, we analyzed MOT results by region and epidemic type, and explored the factors (e.g. data used to estimate parameter inputs, adherence to guidelines influencing the differences. Methods: We systematically searched MEDLINE, EMBASE and UNAIDS reports, and contacted UNAIDS country directors for published MOT results from MOT inception (2003 to 25 September 2012. Results: We retrieved four journal articles and 20 UNAIDS reports covering 29 countries. In 13 countries, the largest FNI (range 26 to 63% was acquired by the low-risk group and increased with low-risk population size. The FNI among female sex workers (FSWs remained low (median 1.3%, range 0.04 to 14.4%, with little variability by region and epidemic type despite variability in sexual behaviour. In India and Thailand, where FSWs play an important role in transmission, the FNI among FSWs was 2 and 4%, respectively. In contrast, the FNI among men who have sex with men (MSM varied across regions (range 0.1 to 89% and increased with MSM population size. The FNI among people who inject drugs (PWID, range 0 to 82% was largest in early-phase epidemics with low overall HIV prevalence. Most MOT studies were conducted and reported as per guidelines but data quality remains an issue. Conclusions: Although countries are generally performing the MOT as per guidelines, there is little variation in the FNI (except among MSM and PWID by region and epidemic type. Homogeneity in MOT FNI for FSWs, clients and low-risk groups may limit the utility of MOT for guiding country-specific interventions in heterosexual HIV epidemics.

  15. Algae and humans share a molybdate transporter.

    2011-04-19

    Almost all living organisms need to obtain molybdenum from the external medium to achieve essential processes for life. Activity of important enzymes such as sulfite oxidase, aldehyde oxidase, xanthine dehydrogenase, and nitrate reductase is strictly dependent on the presence of Mo in its active site. Cells take up Mo in the form of the oxianion molybdate, but the molecular nature of the transporters is still not well known in eukaryotes. MOT1 is the first molybdate transporter identified in plant-type eukaryotic organisms, but it is absent in animal genomes. Here we report a molybdate transporter different from the MOT1 family, encoded by the Chlamydomonas reinhardtii gene MoT2, that is also present in animals including humans. The knockdown of CrMoT2 transcription leads to the deficiency of molybdate uptake activity in Chlamydomonas. In addition, heterologous expression in Saccharomyces cerevisiae of MoT2 genes from Chlamydomonas and humans support the functionality of both proteins as molybdate transporters. Characterization of CrMOT2 and HsMOT2 activities showed an apparent Km of about 550 nM that, though higher than the Km reported for MOT1, still corresponds to high affinity systems. CrMoT2 transcription is activated when extracellular molybdate concentration is low but in contrast to MoT1 is not activated by nitrate. Analysis of protein databases revealed the presence of four motifs present in all the proteins with high similarity to MOT2, that label a previously undescribed family of proteins probably related to molybdate transport. Our results open the way toward the understanding of molybdate transport as part of molybdenum homeostasis and Moco biosynthesis in animals.

    2007-01-01

    An apparatus that serves as a source of a cold beam of atoms contains multiple two-dimensional (2D) magneto-optical traps (MOTs). (Cold beams of atoms are used in atomic clocks and in diverse scientific experiments and applications.) The multiple-2D-MOT design of this cold atom source stands in contrast to single-2D-MOT designs of prior cold atom sources of the same type. The advantages afforded by the present design are that this apparatus is smaller than prior designs.

  17. Cold atom trap with zero residual magnetic field: the ac magneto-optical trap.

    Science.gov (United States)

    Harvey, Matthew; Murray, Andrew James

    2008-10-24

    A novel atom trap is described using alternating current to generate the magnetic B field, together with high speed polarization switching of the damping laser field. This combination produces a trap as effective as a standard magneto-optical trap (MOT), with the advantage that the average B field is zero. No net current is hence induced in surrounding conductive elements, and the B field produced by the ac MOT is found to switch off >300 times faster than a conventional MOT. New experiments can hence be performed, including charged particle probing or detection of the cold target ensemble.

  18. A Magneto-Optical Trap for Polar Molecules

    CERN Document Server

    Stuhl, Benjamin K; Wang, Dajun; Ye, Jun

    2008-01-01

    We propose a method for laser cooling and trapping a substantial class of polar molecules, and in particular titanium (II) oxide (TiO). This method uses pulsed electric fields to nonadiabatically remix the ground-state magnetic sublevels of the molecule, allowing us to build a magneto-optical trap (MOT) based on a quasi-cycling $J'=J"-1$ transition. Monte-Carlo simulations of this electrostatically remixed MOT (ER-MOT) demonstrate the feasibility of cooling TiO to a temperature of 10 $\\mathrm{\\mu}K$ and trapping it with a radiation-pumping-limited lifetime on the order of 80 ms.

    In this paper,ultracold atoms and molecules in a dark magneto-optical trap (MOT) are studied via depumping the cesium cold atoms into the dark hyperfine ground state.The collision rate is reduced to 0.45 s-1 and the density of the atoms is increased to 5.6 × 1011 cm-3 when the fractional population of the atoms in the bright hyperfine ground state is as low as 0.15.The vibrational spectra of the ultracold cesium molecules are also studied in a standard MOT and in a dark MOT separately.The experimental results are analyzed by using the perturbative quantum approach.

  20. Generation of a cold pulsed beam of Rb atoms by transfer from a 3D magneto-optic trap

    CERN Document Server

    Chanu, Sapam Ranjita; Natarajan, Vasant

    2016-01-01

    We demonstrate a technique for producing a cold pulsed beam of atoms by transferring a cloud of atoms trapped in a three dimensional magneto-optic trap (MOT). The MOT is loaded by heating a getter source of Rb atoms. We show that it is advantageous to transfer with two beams (with a small angle between them) compared to a single beam, because the atoms stop interacting with the beams in the two-beam technique, which results in a Gaussian velocity distribution. The atoms are further cooled in optical molasses by turning off the MOT magnetic field before the transfer beams are turned on.

  1. Black hole horizons and quantum charged particles

    CERN Document Server

    Jaramillo, José Luis

    2014-01-01

    We point out a structural similarity between the characterization of black hole apparent horizons as stable marginally outer trapped surfaces (MOTS) and the quantum description of a non-relativistic charged particle moving in given magnetic and electric fields on a closed surface. Specifically, the spectral problem of the MOTS-stability operator corresponds to a stationary quantum particle with a formal fine-structure constant $\\alpha$ of negative sign. We discuss how such analogy enriches both problems, illustrating this with the insights into the MOTS-spectral problem gained from the analysis of the spectrum of the quantum charged particle Hamiltonian.

  2. Two-Color Magneto-Optical Trap with Small Magnetic Field for Ytterbium

    Kawasaki, Akio; Yu, QinQin; Vuletić, Vladan

    2015-01-01

    We report a two-color magneto-optical trap (MOT) for ytterbium atoms operating at a low magnetic field gradient down to 2 G/cm where a conventional MOT using the singlet transition (6s^2 1S0 -> 6s6p 1P1) is unable to trap atoms. By simultaneously applying laser light on both the broad-linewidth singlet transition and the narrow-linewidth triplet transition (6s^2 1S0 -> 6s6p 3P1), we load and trap 4.0 x 10^5 atoms directly from an atomic beam at 700 K. In the two-color MOT, the slowing and trapping functions are separately performed by the singlet transition light and the triplet transition light, respectively. The two-color MOT is highly robust against laser power imbalance even at very low magnetic field gradients.

    2010-01-01

    We present results of the study of a simultaneously confined metastable helium (He*) and rubidium magneto-optical trap (MOT). By monitoring the trap decay of the Rb87 MOT with and without a He* MOT present, we find the light-assisted, two-body loss rate to be βRb-He*=(6±2)×10-10cm3/s. Moreover, we find that it is possible to create a large, robust Rb87-He* MOT, opening the possibility of creating a Rb87-He* Bose-Einstein condensate. This would be the first dual-species condensate incorporating an alkali metal ground-state atom and an excited-state noble gas atom.

    2009-08-03

    We have realized a 4-beam pyramidal magneto-optical trap ideally suited for future microfabrication. Three mirrors split and steer a single incoming beam into a tripod of reflected beams, allowing trapping in the four-beam overlap volume. We discuss the influence of mirror angle on cooling and trapping, finding optimum efficiency in a tetrahedral configuration. We demonstrate the technique using an ex-vacuo mirror system to illustrate the previously inaccessible supra-plane pyramid MOT configuration. Unlike standard pyramidal MOTs both the pyramid apex and its mirror angle are non-critical and our MOT offers improved molasses free from atomic shadows in the laser beams. The MOT scheme naturally extends to a 2-beam refractive version with high optical access. For quantum gas experiments, the mirror system could also be used for a stable 3D tetrahedral optical lattice.

    We report the experimental realization of strontium magneto-optical trap(MOT) operating on the intercombination transition lSo-3 P1 at 689nm, namely red MOT. A 689nm laser used for cooling and trapping is injection locked to a master laser, whose linewidth is narrowed to 150 Hz by locking to a high finesse optical reference cavity.88 Sr atoms pre-cooled and trapped by the broad 1SO-1 Pl transition at 461 nm are transferred to the red MOT with the help of a time sequence controller. The transfer ratio is about 20% and the red MOT's temperature is estimated to be less than 20 μK by the time-of-flight(TOF) image analysis.

    Dutta, Sourav; Sawant, Rahul; Rangwala, S A

    2017-03-17

    We experimentally demonstrate cooling of trapped ions by collisions with cotrapped, higher-mass neutral atoms. It is shown that the lighter ^{39}K^{+} ions, created by ionizing ^{39}K atoms in a magneto-optical trap (MOT), when trapped in an ion trap and subsequently allowed to cool by collisions with ultracold, heavier ^{85}Rb atoms in a MOT, exhibit a longer trap lifetime than without the localized ^{85}Rb MOT atoms. A similar cooling of trapped ^{85}Rb^{+} ions by ultracold ^{133}Cs atoms in a MOT is also demonstrated in a different experimental configuration to validate this mechanism of ion cooling by localized and centered ultracold neutral atoms. Our results suggest that the cooling of ions by localized cold atoms holds for any mass ratio, thereby enabling studies on a wider class of atom-ion systems irrespective of their masses.

    The direct photodissociation of trapped 85Rb2+ (rubidium) molecular ions by the cooling light for the 85Rb magneto-optical trap (MOT) is studied, both experimentally and theoretically. Vibrationally excited Rb2+ ions are created by photoionization of Rb2 molecules formed photoassociatively in the Rb MOT and are trapped in a modified spherical Paul trap. The decay rate of the trapped Rb2+ ion signal in the presence of the MOT cooling light is measured and agreement with our calculated rates for molecular ion photodissociation is observed. The photodissociation mechanism due to the MOT light is expected to be active and therefore universal for all homonuclear diatomic alkali metal molecular ions.

    We report the realization of ytterbium magneto-optical trap (MOT) operating on the dipole-allowed 1S0 - 1P1 transition at 398.9nm. The MOT is loaded by a slowed atomic beam produced by a Zeeman slower. All seven stable isotopes of Yb atoms could be trapped separately at different laser detuning values. Over 107 174Yb atoms are collected in the MOT, whereas the atom number of fermionic isotope 171Yb is roughly 2.3 × 106 due to a lower abundance. Without the Zeeman slower, the trapped atom numbers are one order of magnitude lower.Both the even and odd isotopes are recognized as excellent candidates of optical clock transition, so the cooling and trapping of ytterbium atoms by the blue MOT is an important step for building an optical clock.

  4. An efficient explicit marching on in time solver for magnetic field volume integral equation

    KAUST Repository

    Sayed, Sadeed Bin

    2015-07-25

    An efficient explicit marching on in time (MOT) scheme for solving the magnetic field volume integral equation is proposed. The MOT system is cast in the form of an ordinary differential equation and is integrated in time using a PE(CE)m multistep scheme. At each time step, a system with a Gram matrix is solved for the predicted/corrected field expansion coefficients. Depending on the type of spatial testing scheme Gram matrix is sparse or consists of blocks with only diagonal entries regardless of the time step size. Consequently, the resulting MOT scheme is more efficient than its implicit counterparts, which call for inversion of fuller matrix system at lower frequencies. Numerical results, which demonstrate the efficiency, accuracy, and stability of the proposed MOT scheme, are presented.

    Previous studies have revealed that negative emotion may influence participants' cognitive processing. However, the neural mechanism of the impact of negative emotion on dynamic task like Multiple Object Tracking (MOT) is still unknown. This present study used electrophysiological (Event-Related Potentials, ERP) measures to investigate the effect of negative emotion on MOT tasks. Participants were required to complete MOT tasks while detecting the probe dots that would appear on targets, distractors or the space between them during tracking. Results of N2 amplitude showed that the distractor inhibition effect existed only in the neutral emotional picture condition. The P3 amplitude in the parietal area was also modulated by the emotion condition. P3 amplitude in the occipital area showed a target enhancement effect for both the neutral and negative emotion condition. The present study indicates that negative emotion could affect attention resource allocation during MOT.

    Optics lattice clock is a hot topic in the researches of frequency standard and metrology. Neutral mercury atom is one of the most promising candidates for optical lattice clock. Due to its large atomic number, mercury atom is insensitive to black body radiation, which is the severe limitation for developing the optical lattice clocks. To realize the optical lattice clock of neutral mercury atoms, the first step is to implement laser-cooling and trapping of neutral mercury atoms. The cooling transition of mercury atom is 1S0–3P1 transition. The wavelength is 253.7 nm, the line width is 1.27 MHz, and the saturation intensity is 10.2 mW/cm2. Quantum projection noise (QPN) is an important parameter that affects optical lattice clock. Increasing the loading rate of magneto-optical trap (MOT) can help lower the QPN, thereby improving the performance of optical lattice clock. In this work, we calculate the scattering force of deep UV cooling laser, which is exerted on mercury atom in our single chamber MOT, and numerically simulate the one-dimensional motion of the atom in the MOT. It gives us the capture velocity under optimized parameters of the MOT. Then we calculate the loading rate of three-dimensional MOT by a high efficient random sampling method. According to the rate equation of MOT, the loading rate is proportional to the atom number of the steady state, which is the accessible parameter in the experiment. An experimental setup of MOT is established with a high vacuum system and a frequency quadrupled semiconductor laser system. The fluorescence imaging on an EMCCD gives the atom number in the MOT. We also calibrate the vapor density of background mercury gas in the vacuum, and measure the atom number in a steady MOT. We numerically simulate and experimentally study the influences on the atom number on the parameters of MOT, such as laser intensity, laser detuning and magnetic field gradient. The calculated results are in consistent with the experimental

  11. A Concept for Zero-Alignment Micro Optical Systems

    Energy Technology Data Exchange (ETDEWEB)

    DESCOUR, MICHAEL R.; KOLOLUOMA,TERHO; LEVEY,RAVIV; RANTALA,JUHA T.; SHUL,RANDY J.; WARREN,MIAL E.; WILLISON,CHRISTI LEE

    1999-09-16

    We are developing a method of constructing compact, three-dimensional photonics systems consisting of optical elements, e.g., lenses and mirrors, photo-detectors, and light sources, e.g., VCSELS or circular-grating lasers. These optical components, both active and passive, are mounted on a lithographically prepared silicon substrate. We refer to the substrate as a micro-optical table (MOT) in analogy with the macroscopic version routinely used in optics laboratories. The MOT is a zero-alignment, microscopic optical-system concept. The position of each optical element relative to other optical elements on the MOT is determined in the layout of the MOT photomask. Each optical element fits into a slot etched in the silicon MOT. The slots are etched using a high-aspect-ratio silicon etching (HARSE) process. Additional positioning features in each slot's cross-section and complementary features on each optical element permit accurate placement of that element's aperture relative to the MOT substrate. In this paper we present the results of the first fabrication and micro-assembly experiments of a silicon-wafer based MOT. Based on these experiments, estimates of position accuracy are reported. We also report on progress in fabrication of lens elements in a hybrid sol-gel material (HSGM). Diffractive optical elements have been patterned in a 13-micron thick HSGM layer on a 150-micron thick soda-lime glass substrate. The measured ms surface roughness was 20 nm. Finally, we describe modeling of MOT systems using non-sequential ray tracing (NSRT).

    We report on an experimental method to align a laser beam to a cloud of atoms trapped in a magneto-optical trap (MOT). We show how balanced lock-in detection leads to a very sensitive method to align the laser beam to the atoms in the plane perpendicular to the propagation direction. This provides a very reliable and fast way of aligning laser beams to atoms trapped in a MOT.

  15. Conditional Random Field (CRF-Boosting: Constructing a Robust Online Hybrid Boosting Multiple Object Tracker Facilitated by CRF Learning

    2017-03-01

    Full Text Available Due to the reasonably acceptable performance of state-of-the-art object detectors, tracking-by-detection is a standard strategy for visual multi-object tracking (MOT. In particular, online MOT is more demanding due to its diverse applications in time-critical situations. A main issue of realizing online MOT is how to associate noisy object detection results on a new frame with previously being tracked objects. In this work, we propose a multi-object tracker method called CRF-boosting which utilizes a hybrid data association method based on online hybrid boosting facilitated by a conditional random field (CRF for establishing online MOT. For data association, learned CRF is used to generate reliable low-level tracklets and then these are used as the input of the hybrid boosting. To do so, while existing data association methods based on boosting algorithms have the necessity of training data having ground truth information to improve robustness, CRF-boosting ensures sufficient robustness without such information due to the synergetic cascaded learning procedure. Further, a hierarchical feature association framework is adopted to further improve MOT accuracy. From experimental results on public datasets, we could conclude that the benefit of proposed hybrid approach compared to the other competitive MOT systems is noticeable.

    Bacterial flagellar motors are intricate nanomachines in which the stator units and rotor component FliM may be dynamically exchanged during function. Similar to other bacterial species, the gammaproteobacterium Shewanella putrefaciens CN-32 possesses a complete secondary flagellar system along with a corresponding stator unit. Expression of the secondary system occurs during planktonic growth in complex media and leads to the formation of a subpopulation with one or more additional flagella at random positions in addition to the primary polar system. We used physiological and phenotypic characterizations of defined mutants in concert with fluorescent microscopy on labelled components of the two different systems, the stator proteins PomB and MotB, the rotor components FliM(1) and FliM(2), and the auxiliary motor components MotX and MotY, to determine localization, function and dynamics of the proteins in the flagellar motors. The results demonstrate that the polar flagellum is driven by a Na(+)-dependent FliM(1)/PomAB/MotX/MotY flagellar motor while the secondary system is rotated by a H(+)-dependent FliM(2)/MotAB motor. The components were highly specific for their corresponding motor and are unlikely to be extensively swapped or shared between the two flagellar systems under planktonic conditions. The results have implications for both specificity and dynamics of flagellar motor components. © 2011 Blackwell Publishing Ltd.

    The completion of continuing professional development (CPD) is mandatory for medical oncologists and trainees (MO&T). Pharmaceutical companies may fund some CPD activities, but there is increasing debate about the potential for conflicts of interest (COI). To assess current practices around funding to attend CPD activities. An electronic survey was distributed to Australian MO&T. The survey asked questions about current practices, institutional policies and perceptions about attending CPD funded by pharmaceutical companies. The design looked at comparing responses between MO&T as well as their understanding of and training around institutional and ethical process. A total of 157 of 653 (24%) responses was received, the majority from MO (76%). Most CPD activities attended by MO&T were self-funded (53%), followed by funding from institutions (19%), pharmaceutical companies (16%) and salary award (16%). Most institutions allowed MO&T to receive CPD funding from professional organisations (104/157, 66%) or pharmaceutical companies (90/157, 57%). A minority of respondents (13/157, 8%) reported that the process to use pharmaceutical funds had been considered by an ethics committee. Although 103/157 (66%) had received pharmaceutical funding for CPD, most (109/157, 69%) reported never receiving training about potential COI. The lack of education was more noticeable among trainees (odds ratio (OR) 8.61, P = 0.02). MO&T acknowledged the potential bias towards a pharmaceutical product (P = 0.05) but believed there was adequate separation between themselves and pharmaceutical companies (P < 0.01). Majority of CPD attended by MO&T is self-funded. There is lack of clarity in institutional policies regarding external funding support for CPD activities. Formal education about potential COI is lacking. © 2017 Royal Australasian College of Physicians.

    Frozen-thawed boar sperm (FTS) has reduced in vitro and in vivo life span compared to liquid semen. Experiments tested whether extenders, thawing procedures, and storage temperatures could extend the fertile life span of FTS. Experiment 1 tested the effect of six extenders on postthaw motility (MOT) and viability (VIA). Straws from boars (n = 6) were thawed, diluted into each extender, and evaluated at 20, 60, and 120 minutes. There was a trend (P = 0.08) for an extender-by-time interaction for MOT and effect of extender and time for MOT (P boar ejaculates (n = 15) were thawed at 50 °C for 10, 20, or 30 seconds or at 70 °C for 5, 10, or 20 seconds and evaluated at 5, 30, and 60 minutes. There was an effect of thawing treatment on MOT, VIA, and ACR (viable sperm with intact acrosomes, P < 0.0001) and an effect of time of evaluation (P < 0.0001) on MOT and ACR. Thawing at 70 °C for 20 seconds reduced (P < 0.05) MOT, VIA, and ACR compared to other treatments. Experiment 3 tested the effects of storage temperature and time after thawing using 20 ejaculates. Samples were thawed, diluted, and allotted to storage at 17 °C, 26 °C, or 37 °C with evaluation at 2, 6, 12, and 24 hours. There was a storage temperature and time effect and an interaction for MOT and VIA (P < 0.0001). Storage at 17 °C and 26 °C increased (P < 0.05) MOT over all times (38.5%) compared to 37 °C (26%), whereas MOT was reduced at intervals. Viability was also greatest with 17 °C and 26 °C compared to 37 °C and was also affected by time and decreased with time. These results indicate that FTS can be held at 17 °C or 26 °C for up to 2 hours before use and would allow for preparation of multiple doses. These data suggest in vitro fertility of FTS is affected by extenders, thawing, and storage.

  19. A Stable Marching on-in-time Scheme for Solving the Time Domain Electric Field Volume Integral Equation on High-contrast Scatterers

    KAUST Repository

    Sayed, Sadeed Bin

    2015-05-05

    A time domain electric field volume integral equation (TD-EFVIE) solver is proposed for characterizing transient electromagnetic wave interactions on high-contrast dielectric scatterers. The TD-EFVIE is discretized using the Schaubert- Wilton-Glisson (SWG) and approximate prolate spherical wave (APSW) functions in space and time, respectively. The resulting system of equations can not be solved by a straightforward application of the marching on-in-time (MOT) scheme since the two-sided APSW interpolation functions require the knowledge of unknown “future” field samples during time marching. Causality of the MOT scheme is restored using an extrapolation technique that predicts the future samples from known “past” ones. Unlike the extrapolation techniques developed for MOT schemes that are used in solving time domain surface integral equations, this scheme trains the extrapolation coefficients using samples of exponentials with exponents on the complex frequency plane. This increases the stability of the MOT-TD-EFVIE solver significantly, since the temporal behavior of decaying and oscillating electromagnetic modes induced inside the scatterers is very accurately taken into account by this new extrapolation scheme. Numerical results demonstrate that the proposed MOT solver maintains its stability even when applied to analyzing wave interactions on high-contrast scatterers.

    The aims were to evaluate the susceptibility of feline ejaculated and epididymal spermatozoa to cold shock and to evaluate the effect of egg yolk in the preservation extender. Ejaculated and epididymal spermatozoa from eight males were subjected to a slow (0.5 degrees C/min) or a fast (3 degrees C/min) cooling rate with controls kept in room temperature. Ejaculated and epididymal spermatozoa from another eight males were cooled in a plain Tris buffer (Tris) or in Tris with 20% egg yolk (EYT) and evaluated for 96 h. Subjective motility (MOT), plasma membrane integrity (PMI), and acrosome integrity (ACRI) were evaluated. Cooling did not induce sperm damage regarding PMI (P=0.6) or ACRI (P=0.19) and chilled spermatozoa had better overall MOT (P=0.046) than controls. EYT was better for MOT (P>0.05) from 48 h of cold storage than Tris. EYT was also better for overall ACRI (P0.05) for PMI or ACRI. Ejaculated spermatozoa had better overall MOT (Pegg yolk as there were no interactions (P>0.05) between source of spermatozoa and treatment (cooling or control) or between time, source and extender (P>0.05). In conclusion cat spermatozoa were tolerant to cold shock and egg yolk was beneficial for preservation of MOT and ACRI but not PMI.

  1. Magneto-optical Trapping of a Diatomic Molecule

    2014-05-01

    The magneto-optical trap (MOT) is the workhorse technique for atomic physics in the ultracold regime, serving as the starting point in applications from optical clocks to quantum-degenerate gases. Although MOTs have been used with a wide array of atomic species, realization of a molecular MOT was long considered infeasible. In this talk we will describe the first magneto-optical trap for a molecule, strontium monofluoride (SrF). Our MOT produces the coldest trapped sample of directly-cooled molecules to date, with temperature T ~2.5 mK. The SrF MOT is loaded from a cryogenic buffer-gas beam slowed by laser radiation pressure. Images of laser-induced fluorescence allow us to characterize the trap's properties. Although magneto-optical trapping of diatomic molecules is in its infancy, our results indicate that access to the ultracold regime may be possible for several molecular species, with potential applications from quantum simulation to tests of fundamental symmetries to ultracold chemistry.

    A low-cost magneto-optical trap (MOT) for ultra-cold atoms is a wonderful tool for undergraduate research and teaching laboratories that highlights many topics in modern physics. We researched and created such a MOT using two external-cavity diode lasers, two laser locking systems, optics, magnetic coils, and Rubidium vapor cells. At our undergraduate institution, we chose a combination of equipment that we fabricated ourselves together with some purchased items as an optimum balance between cost and building time. However, an emphasis was placed upon self-construction of components, such as machining the laser cavities and constructing the majority of the circuitry within the institution. The total cost of our MOT was about 25,000. We were successfully able to trap more than 10 million Rubidium atoms in 1 cubic centimeter. Such a MOT is a feasible addition to any undergraduate course of study. The theory of operation and construction methods of our MOT will be presented along with our first measurement results.

    We report on the progress of the FrPNC collaboration towards Parity Non Conservation Measurements (PNC) using francium atoms at the TRIUMF accelerator. We demonstrate efficient transfer (higher than 40%) to the science vacuum chamber where the PNC measurements will be performed. The transfer uses a downward resonant push beam from the high-efficiency capture magneto optical trap (MOT) towards the science chamber where the atoms are recaptured in a second MOT. The transfer is very robust with respect to variations in the parameters (laser power, detuning, alignment, etc.). We accumulate a growing number of atoms at each transfer pulse (limited by the lifetime of the MOT) since the push beam does not eliminate the atoms already trapped in the science MOT. The number of atoms in the science MOT is on track to meet the requirements for competitive PNC measurements when high francium rates (previously demonstrated) are delivered to our apparatus. The catcher/neutralizer for the ion beam has been tested reliably to 100,000 heating/motion cycles. We present initial tests on the direct microwave excitation of the ground hyperfine transition at 45 GHz. Support from NSERC and NRC from Canada, NSF and Fulbright from USA, and CONACYT from Mexico.

  10. Elucidating the origin of the ExbBD components of the TonB system through Bayesian inference and maximum-likelihood phylogenies.

    Uptake of ferric siderophores, vitamin B12, and other molecules in gram-negative bacteria is mediated by a multi-protein complex known as the TonB system. The ExbB and ExbD protein components of the TonB system play key energizing roles and are homologous with the flagellar motor proteins MotA and MotB. Here, the phylogenetic relationships of ExbBD and MotAB were investigated using Bayesian inference and the maximum-likelihood method. Phylogenetic trees of these proteins suggest that they are separated into distinct monophyletic groups and have originated from a common ancestral system. Several horizontal gene transfer events for ExbB-ExbD are also inferred, and a model for the evolution of the TonB system is proposed. Copyright © 2013 Elsevier Inc. All rights reserved.

    In recent years, tremendous progress has been made in laser cooling and trapping of molecules. With the achievement of a magneto-optical trap (MOT) for the diatomic molecule SrF, a range of novel experiments employing ultracold molecules may be within reach. Here we present planned improvements to our SrF MOT apparatus, including plans for more efficient MOT loading, sub-Doppler cooling, loading into a conservative trap, and co-trapping of atoms. These and other improvements should allow increases in trapped molecule number, lifetime, and phase-space density. We illustrate some of the experiments that will be enabled by these improvements, such as studies of inelastic and reactive atom-molecule collisions at ultracold temperatures and investigations of sympathetic and evaporative cooling of SrF.

    We report white-light slowing of calcium monofluoride molecules. A single main laser (606 nm) plus two additional vibrational repump lasers (628 nm) are employed. The slowing lasers are spectrally broadened to address the molecules' velocity spread and hyperfine splittings. We use a background-free two-photon fluorescence detection scheme to make high signal-to-noise measurements of our molecular beam's longitudinal velocity distribution. This method is applied to slow CaF produced by a two-stage cryogenic buffer gas beam source by > 30 m/s to near the capture velocity of a molecular magneto-optical trap (MOT). Due to the presence of magnetic dark states which inhibit optical cycling, we will use an AC-MOT. We characterize the performance of this AC-MOT used in the trapping of Li and Yb.

  16. Stability of Magneto-optical Traps with Large Field Gradients: Limits on the Tight Confinement of Single Atoms

    Willems, P.; Boyd, R.; Bliss, J.; Libbrecht, K. [Norman Bridge Laboratory of Physics, 264-33 California Institute of Physics, Pasadena, California 91125 (United States)

    1997-03-01

    We report measurements of the stability of magneto-optical traps (MOTs) for neutral atoms in the limit of tight confinement of a single atom. For quadrupole magnetic field gradients at the trap center greater than {approximately}1kG/cm, we find that stochastic diffusion of atoms out of the trapping volume becomes the dominant particle loss mechanism, ultimately limiting the MOT size to greater than {approximately}5{mu}m. We measured and modeled the diffusive loss rate as a function of laser power, detuning, and field gradient for trapped cesium atoms. In addition, for as few as two atoms, the collisional loss rates become very high for tightly confined traps, allowing the direct observation of isolated two-body atomic collisions in a MOT. {copyright} {ital 1997} {ital The American Physical Society}

    We experimentally and theoretically study the continuous accumulation of cold atoms from a magneto-optical trap (MOT) into a finite depth trap, consisting in a magnetic quadrupole trap dressed by a radiofrequency (RF) field. Chromium atoms (52 isotope) in a MOT are continuously optically pumped by the MOT lasers to metastable dark states. In presence of a RF field, the temperature of the metastable atoms that remain magnetically trapped can be as low as 25 microK, with a density of 10^17 atoms.m-3, resulting in an increase of the phase-space density, still limited to 7.10^-6 by inelastic collisions. To investigate the thermalization issues in the truncated trap, we measure the free evaporation rate in the RF-truncated magnetic trap, and deduce the average elastic cross section for atoms in the 5D4 metastable states, equal to 7.0 10^-16m2.

  18. A Young-Laplace law for black hole horizons

    2013-01-01

    Black hole horizon sections, modelled as marginally outer trapped surfaces (MOTS), possess a notion of stability admitting a spectral characterization. Specifically, the "principal eigenvalue" \\lambda_o of the MOTS-stability operator (an elliptic operator on horizon sections) must be non-negative. We discuss the expression of \\lambda_o for axisymmetric stationary black hole horizons and show that, remarkably, it presents the form of the Young-Laplace law for soap bubbles in equilibrium, if \\lambda_o is identified with a formal pressure difference between the inner and outer sides of the "bubble". In this view, that endorses the existing fluid analogies for black hole horizons, MOTS-stability is interpreted as a consequence of a pressure increase in the black hole trapped region.

    An inertial sensing system includes a magneto-optical trap (MOT) that traps atoms within a specified trapping region. The system also includes a cooling laser that cools the trapped atoms so that the atoms remain within the specified region for a specified amount of time. The system further includes a light-pulse atom interferometer (LPAI) that performs an interferometric interrogation of the atoms to determine phase changes in the atoms. The system includes a controller that controls the timing of MOT and cooling laser operations, and controls the timing of interferometric operations to substantially recapture the atoms in the specified trapping region. The system includes a processor that determines the amount inertial movement of the inertial sensing system based on the determined phase changes in the atoms. Also, a method of inertial sensing using this inertial sensing system includes recapture of atoms within the MOT following interferometric interrogation by the LPAI.

    We present a novel technique for measuring the characteristics of a magneto-optical trap (MOT) for cold atoms by monitoring the spontaneous emission from trapped atoms coupled into the guided mode of a tapered optical nanofiber. We show that the nanofiber is highly sensitive to very small numbers of atoms close to its surface. The size and shape of the MOT, determined by translating the cold atom cloud across the tapered fiber, is in excellent agreement with measurements obtained using the conventional method of fluorescence imaging using a charge coupled device camera. The coupling of atomic fluorescence into the tapered fiber also allows us to monitor the loading and lifetime of the trap. The results are compared to those achieved by focusing the MOT fluorescence onto a photodiode and it was seen that the tapered fiber gives slightly longer loading and lifetime measurements due to the sensitivity of the fiber, even when very few atoms are present.

    We present measurments of optical trapping and cooling and magnetic trapping of ^39K in a double-MOT apparatus. (Optics Lett. 21, 290(1996)) We have measured light-assisted collisional loss rates from our second MOT over a range of trap light intensities. At an intensity of 10 mW/cm^2 we find a loss rate parameter β of 2 x 10-11 cc/s. β increases with trap light intensity and is consistent with the values measured by Williamson and Walker (JOSA B 12, 1393 (1995)). We also present studies of the temperature of atoms in a MOT of ^39K. Under certain conditions of repump light intensity and trap light detuning we measure temperatures nearly as low as the Doppler Limit. Finally, we report on prelimiary results of magnetic trapping in which we have trapped several 10^7 atoms in a quadrupole magnetic trap.

  5. Effects of taurine supplementation on hepatic markers of inflammation and lipid metabolism in mothers and offspring in the setting of maternal obesity.

    Full Text Available Maternal obesity is associated with obesity and metabolic disorders in offspring. However, intervention strategies to reverse or ameliorate the effects of maternal obesity on offspring health are limited. Following maternal undernutrition, taurine supplementation can improve outcomes in offspring, possibly via effects on glucose homeostasis and insulin secretion. The effects of taurine in mediating inflammatory processes as a protective mechanism has not been investigated. Further, the efficacy of taurine supplementation in the setting of maternal obesity is not known. Using a model of maternal obesity, we examined the effects of maternal taurine supplementation on outcomes related to inflammation and lipid metabolism in mothers and neonates. Time-mated Wistar rats were randomised to either: 1 control : control diet during pregnancy and lactation (CON; 2 CON supplemented with 1.5% taurine in drinking water (CT; 3 maternal obesogenic diet (high fat, high fructose during pregnancy and lactation (MO; or 4 MO supplemented with taurine (MOT. Maternal and neonatal weights, plasma cytokines and hepatic gene expression were analysed. A MO diet resulted in maternal hyperinsulinemia and hyperleptinemia and increased plasma glucose, glutamate and TNF-α concentrations. Taurine normalised maternal plasma TNF-α and glutamate concentrations in MOT animals. Both MO and MOT mothers displayed evidence of fatty liver accompanied by alterations in key markers of hepatic lipid metabolism. MO neonates displayed a pro-inflammatory hepatic profile which was partially rescued in MOT offspring. Conversely, a pro-inflammatory phenotype was observed in MOT mothers suggesting a possible maternal trade-off to protect the neonate. Despite protective effects of taurine in MOT offspring, neonatal mortality was increased in CT neonates, indicating possible adverse effects of taurine in the setting of normal pregnancy. These data suggest that maternal taurine supplementation

    Bacterial flagellar motility is a complex cellular behavior required for the colonization of the light-emitting organ of the Hawaiian bobtail squid, Euprymna scolopes, by the beneficial bioluminescent symbiont Vibrio fischeri. We characterized the basis of this behavior by performing (i) a forward genetic screen to identify mutants defective in soft-agar motility, as well as (ii) a transcriptional analysis to determine the genes that are expressed downstream of the flagellar master regulator FlrA. Mutants with severe defects in soft-agar motility were identified due to insertions in genes with putative roles in flagellar motility and in genes that were unexpected, including those predicted to encode hypothetical proteins and cell division-related proteins. Analysis of mutants for their ability to enter into a productive symbiosis indicated that flagellar motility mutants are deficient, while chemotaxis mutants are able to colonize a subset of juvenile squid to light-producing levels. Thirty-three genes required for normal motility in soft agar were also downregulated in the absence of FlrA, suggesting they belong to the flagellar regulon of V. fischeri. Mutagenesis of putative paralogs of the flagellar motility genes motA, motB, and fliL revealed that motA1, motB1, and both fliL1 and fliL2, but not motA2 and motB2, likely contribute to soft-agar motility. Using these complementary approaches, we have characterized the genetic basis of flagellar motility in V. fischeri and furthered our understanding of the roles of flagellar motility and chemotaxis in colonization of the juvenile squid, including identifying 11 novel mutants unable to enter into a productive light-organ symbiosis. © 2013 The Authors.

  7. Learning strategy trumps motivational level in determining learning-induced auditory cortical plasticity.

    Science.gov (United States)

    Bieszczad, Kasia M; Weinberger, Norman M

    2010-02-01

    Associative memory for auditory-cued events involves specific plasticity in the primary auditory cortex (A1) that facilitates responses to tones which gain behavioral significance, by modifying representational parameters of sensory coding. Learning strategy, rather than the amount or content of learning, can determine this learning-induced cortical (high order) associative representational plasticity (HARP). Thus, tone-contingent learning with signaled errors can be accomplished either by (1) responding only during tone duration ("tone-duration" strategy, T-Dur), or (2) responding from tone onset until receiving an error signal for responses made immediately after tone offset ("tone-onset-to-error", TOTE). While rats using both strategies achieve the same high level of performance, only those using the TOTE strategy develop HARP, viz., frequency-specific decreased threshold (increased sensitivity) and decreased bandwidth (increased selectivity) (Berlau & Weinberger, 2008). The present study challenged the generality of learning strategy by determining if high motivation dominates in the formation of HARP. Two groups of adult male rats were trained to bar-press during a 5.0kHz (10s, 70dB) tone for a water reward under either high (HiMot) or moderate (ModMot) levels of motivation. The HiMot group achieved a higher level of correct performance. However, terminal mapping of A1 showed that only the ModMot group developed HARP, i.e., increased sensitivity and selectivity in the signal-frequency band. Behavioral analysis revealed that the ModMot group used the TOTE strategy while HiMot subjects used the T-Dur strategy. Thus, type of learning strategy, not level of learning or motivation, is dominant for the formation of cortical plasticity.

    We describe the apparatus of a dark-line two-dimensional (2D) magneto-optical trap (MOT) of (85)Rb cold atoms with high optical depth (OD). Different from the conventional configuration, two (of three) pairs of trapping laser beams in our 2D MOT setup do not follow the symmetry axes of the quadrupole magnetic field: they are aligned with 45° angles to the longitudinal axis. Two orthogonal repumping laser beams have a dark-line volume in the longitudinal axis at their cross over. With a total trapping laser power of 40 mW and repumping laser power of 18 mW, we obtain an atomic OD up to 160 in an electromagnetically induced transparency (EIT) scheme, which corresponds to an atomic-density-length product NL = 2.05 × 10(15) m(-2). In a closed two-state system, the OD can become as large as more than 600. Our 2D MOT configuration allows full optical access of the atoms in its longitudinal direction without interfering with the trapping and repumping laser beams spatially. Moreover, the zero magnetic field along the longitudinal axis allows the cold atoms maintain a long ground-state coherence time without switching off the MOT magnetic field, which makes it possible to operate the MOT at a high repetition rate and a high duty cycle. Our 2D MOT is ideal for atomic-ensemble-based quantum optics applications, such as EIT, entangled photon pair generation, optical quantum memory, and quantum information processing.

  9. A Time Marching Scheme for Solving Volume Integral Equations on Nonlinear Scatterers

    KAUST Repository

    Bagci, Hakan

    2015-01-07

    Transient electromagnetic field interactions on inhomogeneous penetrable scatterers can be analyzed by solving time domain volume integral equations (TDVIEs). TDVIEs are oftentimes solved using marchingon-in-time (MOT) schemes. Unlike finite difference and finite element schemes, MOT-TDVIE solvers require discretization of only the scatterers, do not call for artificial absorbing boundary conditions, and are more robust to numerical phase dispersion. On the other hand, their computational cost is high, they suffer from late-time instabilities, and their implicit nature makes incorporation of nonlinear constitutive relations more difficult. Development of plane-wave time-domain (PWTD) and FFT-based schemes has significantly reduced the computational cost of the MOT-TDVIE solvers. Additionally, latetime instability problem has been alleviated for all practical purposes with the development of accurate integration schemes and specially designed temporal basis functions. Addressing the third challenge is the topic of this presentation. I will talk about an explicit MOT scheme developed for solving the TDVIE on scatterers with nonlinear material properties. The proposed scheme separately discretizes the TDVIE and the nonlinear constitutive relation between electric field intensity and flux density. The unknown field intensity and flux density are expanded using half and full Schaubert-Wilton-Glisson (SWG) basis functions in space and polynomial temporal interpolators in time. The resulting coupled system of the discretized TDVIE and constitutive relation is integrated in time using an explicit P E(CE) m scheme to yield the unknown expansion coefficients. Explicitness of time marching allows for straightforward incorporation of the nonlinearity as a function evaluation on the right hand side of the coupled system of equations. Consequently, the resulting MOT scheme does not call for a Newton-like nonlinear solver. Numerical examples, which demonstrate the applicability

    On paleo-climatic timescales heavy noble gases (Krypton and Xenon) are passively cycled through the atmosphere-ocean system without seeing any significant sink or source. Since the solubility in water of each gas species is characterized by a specific temperature dependency, mixing ratios in the atmosphere change with changing ocean temperatures. In this study, we use this fact to reconstruct mean global ocean temperatures (MOT) over the course of the last glacial transition based on measurements of trapped air in the WAIS Divide ice core. We analyzed 70 ice samples with a recently developed method which determines the isotopic ratios of N2, Ar, Kr (and in some cases also of Xe, though with less precision) and the elemental ratios of Kr/N2, Xe/N2 and Xe/Kr. We use the isotope ratios to correct the elemental ratios for gravitational enrichment in the firn column. The corrected elemental ratios are then used in a simple box model to reconstruct MOT. The three elemental ratio pairs are first interpreted as independent measures of MOT and then combined to a single "best-estimate" MOT record with an average uncertainty of 0.27°C. We find a clear link to Antarctic temperatures and a LGM-Holocene change in MOT of 2.4°C. This value is in good agreement with results from marine sediment cores (which, however, have an uncertainty of 1°C). Our record provides an unprecedented constrain on ocean heat uptake over the last glacial transition and therefore gives new insights in the mechanisms underlying long term ocean heat fluxes. To our knowledge, this is the first time that MOT has been reconstructed in such great detail.

    Molybdenum is an essential element for almost all living beings, which, in the form of a molybdopterin-cofactor, participates in the active site of enzymes involved in key reactions of carbon, nitrogen, and sulfur metabolism. This metal is taken up by cells in form of the oxyanion molybdate. Bacteria acquire molybdate by an ATP-binding-cassette (ABC) transport system in a widely studied process, but how eukaryotic cells take up molybdenum is unknown because molybdate transporters have not been identified so far. Here, we report a eukaryotic high-affinity molybdate transporter, encoded by the green alga Chlamydomonas reinhardtii gene MoT1. An antisense RNA strategy over the MoT1 gene showed that interference of the expression of this gene leads to the inhibition of molybdate transport activity and, in turn, of the Mo-containing enzyme nitrate reductase, indicating a function of MoT1 in molybdate transport. MOT1 functionality was also shown by heterologous expression in Saccharomyces cerevisiae. Molybdate uptake mediated by MOT1 showed a K(m) of approximately 6 nM, which is the range of the lowest K(m) values reported and was activated in the presence of nitrate. Analysis of deduced sequence from the putative protein coded by MoT1 showed motifs specifically conserved in similar proteins present in the databases, and defines a family of membrane proteins in both eukaryotes and prokaryotes probably involved in molybdate transport and distantly related to plant sulfate transporters SULTR. These findings represent an important step in the understanding of molybdate transport, a crucial process in eukaryotic cells.

  13. Mixed Discretization of the Time Domain MFIE at Low Frequencies

    KAUST Repository

    Ulku, Huseyin Arda

    2017-01-10

    Solution of the magnetic field integral equation (MFIE), which is obtained by the classical marching on-in-time (MOT) scheme, becomes inaccurate when the time step is large, i.e., under low-frequency excitation. It is shown here that the inaccuracy stems from the classical MOT scheme’s failure to predict the correct scaling of the current’s Helmholtz components for large time steps. A recently proposed mixed discretization strategy is used to alleviate the inaccuracy problem by restoring the correct scaling of the current’s Helmholtz components under low-frequency excitation.

    Since the invention of magneto-optical trap (MOT), there have been several experimental and theoretical studies of the density distribution in these devices. To the best of our knowledge, only horizontal orbital traps have been observed, perpendicular to the coil axis. In this work we report the observation of distributions of trapped atoms in pure circular orbits without a nucleus whose orbital plane is tilted up to 90diam. with respect to the horizontal plane. We have used a stabilized time phase optical array in our experiments and conventional equipment used for MOT. (Author)

    The relationships among clinical outcomes, academic success, and predictors used to screen applicants for entrance into a Master in Occupational Therapy Program (MOT) were examined. The dependent variables were grade point average in occupational therapy courses (OT-GPA), client therapy outcomes at the clinic, and ratings of MOT students by Level II Fieldwork supervisors. Predictor variables included undergraduate GPA, scores on the Graduate Record Examination (GRE), and an essay. Both undergraduate GPA and scores on the GRE were found to predict OT-GPA. The analytical section of the GRE was also positively correlated with fieldwork supervisors' ratings of students.

    We describe the realization of a DC electric field trap for ultracold polar molecules, the Thin WIre electroStatic Trap (TWIST). The thin wires that form the electrodes of the TWIST allow us to superimpose the trap onto a magneto-optical trap (MOT). In our experiment, ultracold polar NaCs molecules in their electronic ground state are created in the MOT via photoassociation, achieving a continuous accumulation in the TWIST of molecules in low-field seeking states. Initial measurements show that the TWIST trap lifetime is limited only by the background pressure in the chamber.

    We demonstrate one- and two-dimensional transverse laser cooling and magneto-optical trapping of the polar molecule yttrium (II) oxide (YO). In a 1D magneto-optical trap (MOT), we characterize the magneto-optical trapping force and decrease the transverse temperature by an order of magnitude, from 25 to 2 mK, limited by interaction time. In a 2D MOT, we enhance the intensity of the YO beam and reduce the transverse temperature in both transverse directions. The approach demonstrated here can be applied to many molecular species and can also be extended to 3D.

Compared with a known MOT formed by circularly polarised waves (σ+ - σ- configuration), the suggested configuration of the trap formed by fields of ɛ - θ - ɛ¯ configuration allows deeper sub-Doppler cooling of trapped 24Mg atoms, which cannot be implemented in a conventional trap formed by fields of σ+ - σ- configuration.

    Full Text Available Most bacteria that swim are propelled by flagellar filaments, which are driven by a rotary motor powered by proton flux. The mechanism of the flagellar motor is discussed by reforming the model proposed by the present authors in 2005. It is shown that the mean strength of Coulomb field produced by a proton passing the channel is very strong in the Mot assembly so that the Mot assembly can be a shear force generator and induce the flagellar rotation. The model gives clear calculation results in agreement with experimental observations, e g., for the charasteristic torque-velocity relationship of the flagellar rotation.

  6. A perspective on Black Hole Horizons from the Quantum Charged Particle

    CERN Document Server

    Jaramillo, José Luis

    2016-01-01

    Black hole apparent horizons possess a natural notion of stability, whose spectral characterization can be related to the problem of the stationary quantum charged particle. Such mathematical relation leads to an "analyticity conjecture" on the dependence of the spectral properties on a complex "fine-structure-constant" parameter, that can reduce the study of the spectrum of the (non-selfadjoint) MOTS-stability operator to that of the (selfadjoint) Hamiltonian of the quantum charged particle. Moreover, this perspective might open an avenue to the spinorial treatment of apparent horizon (MOTS-)stability and to the introduction of semiclassical tools to explore some of the qualitative aspects of this black hole spectral problem.

    We report the capture of cold strontium atoms in a magneto-optical trap (MOT) at a rate of 4 x 10(10) atoms/s. The MOT is loaded from an atomic beam decelerated by a Zeeman slower operating with a focused laser beam. The 461-nm laser, used for both cooling and trapping, was generated by sum-frequency mixing in a KTP crystal with diode lasers at 813 nm and a Nd:YAG laser at 1064 nm. As much as 115 mW of blue light was obtained.

  8. Cold Strontium Ion Source for Ion Interferometry

    Jackson, Jarom; Durfee, Dallin

    2015-05-01

    We are working on a cold source of Sr Ions to be used in an ion interferometer. The beam will be generated from a magneto-optical trap (MOT) of Sr atoms by optically ionizing atoms leaking out a carefully prepared hole in the MOT. A single laser cooling on the resonant transition (461 nm) in Sr should be sufficient for trapping, as we've calculated that losses to the atom beam will outweigh losses to dark states. Another laser (405 nm), together with light from the trapping laser, will drive a two photon transition in the atom beam to an autoionizing state. Supported by NSF Award No. 1205736.

    We demonstrate significantly improved magneto-optical trapping of molecules using a very slow cryogenic beam source and either rf modulated or dc magnetic fields. The rf magneto-optical trap (MOT) confines 1.0 (3 )×105 CaF molecules at a density of 7 (3 )×106 cm-3 , which is an order of magnitude greater than previous molecular MOTs. Near Doppler-limited temperatures of 340 (20 ) μ K are attained. The achieved density enables future work to directly load optical tweezers and create optical arrays for quantum simulation.

  13. Explicit solution of the time domain volume integral equation using a stable predictor-corrector scheme

    KAUST Repository

    Al Jarro, Ahmed

    2012-11-01

    An explicit marching-on-in-time (MOT) scheme for solving the time domain volume integral equation is presented. The proposed method achieves its stability by employing, at each time step, a corrector scheme, which updates/corrects fields computed by the explicit predictor scheme. The proposedmethod is computationally more efficient when compared to the existing filtering techniques used for the stabilization of explicit MOT schemes. Numerical results presented in this paper demonstrate that the proposed method maintains its stability even when applied to the analysis of electromagnetic wave interactions with electrically large structures meshed using approximately half a million discretization elements.

  19. EFFECTS AND MECHANISM OF STRESS AND OF CRFMICROINJECTION INTO PVN ON GASTRIC EMPTYING

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Objective To study the effects of wrap-restraint stress and of CRF or CRF antagonist (α-helical-CRF9-41) mi croinjection on gastric emptying, and the role of plasma motilin (Mot). Methods The effects of wrap-restraint stress or CRF and CRF antagonist microinjection into paraventricular nucleus ( PVN) on gastric emptying were determined by using dextran blue-2000 as a marker. The plasma level of Mot was determined by radioimmunoassay. Results Wrap-restraint stress inhibi ted gastric emptying. Microinjection of CRF into PVN inhibited gastric emptying dose-dependently. In normal condition, α-he lical-CRF9-41 bilaterally microinjected into PVN didn ' t modify gastric emptying; however, α-helical-CRF9-41 microinjection bi laterally into PVN 15min before wrap-restraint stress could significantly antagonize the effect of stress on gastric emptying. After 30min of stress or CRF microinjection into PVN, plasma levels of Mot significantly decreased, as compared with the normal control group. Conelusion Wrap-restraint stress can inhibit gastric emptying, and microinjection of CRF into PVN has the similar effect. The PVN is one of the specific sites for the action of CRF affecting on gastric emptying. Plasma Mot might partic ipate in the effects of stress and CRF-indluced alteration of gastric emptying.

    2016-01-01

    A novel cesium (Cs) two-color magneto-optical trap (TC-MOT), which partially employs the optical radiation forces due to photon scattering of the 6P3/2 (F'=5) - 7S1/2 (F"=4) excited-state transition in the Cs 6S1/2 - 6P3/2 - 7S1/2 (852 + 1470 nm) ladder-type system, has been proposed and experimentally investigated. One of the three pairs of 852 nm cooling/trapping beams (CTBs) in a conventional Cs MOT is replaced with a pair of the 1470 nm CTBs (type-I) or with one 852 nm CTB plus another counter-propagating 1470 nm CTB (type-II). Both the type-I and type-II Cs TC-MOTs can cool and trap atoms on both the red- and blue-detuning sides of the two-photon resonance. The Cs TC-MOT demonstrated in this work may have applications in the background-free detection of cooled and trapped atoms, and the photon-pair sources compatible with the ensemble-based quantum memory and the long-distance quantum communication via optical fiber.

    2016-04-15

    We describe the design, construction, and operation of a versatile dual-species Zeeman slower for both Cs and Yb, which is easily adaptable for use with other alkali metals and alkaline earths. With the aid of analytic models and numerical simulation of decelerator action, we highlight several real-world problems affecting the performance of a slower and discuss effective solutions. To capture Yb into a magneto-optical trap (MOT), we use the broad {sup 1}S{sub 0} to {sup 1}P{sub 1} transition at 399 nm for the slower and the narrow {sup 1}S{sub 0} to {sup 3}P{sub 1} intercombination line at 556 nm for the MOT. The Cs MOT and slower both use the D2 line (6{sup 2}S{sub 1/2} to 6{sup 2}P{sub 3/2}) at 852 nm. The slower can be switched between loading Yb or Cs in under 0.1 s. We demonstrate that within a few seconds the Zeeman slower loads more than 10{sup 9} Yb atoms and 10{sup 8} Cs atoms into their respective MOTs. These are ideal starting numbers for further experiments on ultracold mixtures and molecules.

    2014-01-01

    We present experimental results from a new scheme for magneto-optically trapping strontium monofluoride (SrF) molecules, which provides increased confinement compared to our original work. The improved trap employs a new approach to magneto-optical trapping presented by M. Tarbutt, \\emph{arXiv preprint} 1409.0244, which provided insight for the first time into the source of the restoring force in magneto-optical traps (MOTs) where the cycling transition includes dark Zeeman sublevels (known as type-II MOTs). We measure a radial spring constant $20\\times$ greater than in our original work with SrF, comparable to the spring constants reported in atomic type-II MOTs. We achieve a trap lifetime $\\tau_{\\rm{MOT}}=136(2)$~ms, over $2\\times$ longer than originally reported for SrF. Finally, we demonstrate further cooling of the trapped molecules by briefly increasing the trapping lasers' detunings. Our trapping scheme remains a straightforward extension of atomic techniques and marks a step towards the direct product...

    In this article, we report the measurement of collision-induced loss rate coefficients βLi, Rb and βRb, Li, and also discuss means to significantly suppress such collision-induced losses. We first describe our dual-species magneto-optical trap (MOT) that allows us to simultaneously trap ≥5 × 108 7Li atoms loaded from a Zeeman slower and ≥2 × 108 85Rb atoms loaded from a dispenser. We observe strong interspecies collision-induced losses in the MOTs which dramatically reduce the maximum atom number achievable in the MOTs. We measure the trap loss rate coefficients βLi, Rb and βRb, Li, and, from a study of their dependence on the MOT parameters, determine the cause for the losses observed. Our results provide valuable insights into ultracold collisions between 7Li and 85Rb, guide our efforts to suppress collision-induced losses, and also pave the way for the production of ultracold 7Li85Rb molecules.

    We present measurements of the total elastic and resonant charge-exchange ion-atom collision rate coefficient $k_\\mathrm{ia}$ of cold sodium (\\ce{Na}) with optically-dark low energy \\ce{Na+} ions in a hybrid ion-neutral trap. To determine $k_\\mathrm{ia}$, we measured the trap loading and loss from both a \\ce{Na} magneto-optical trap (MOT) and a linear radio frequency quadrupole Paul trap. We found the total rate coefficient to be $7.4 \\pm 1.9 \\times 10^{-8}$ cm$^3$/s for the type I \\ce{Na} MOT immersed within an $\\approx 140$ K ion cloud and $1.10 \\pm 0.25 \\times 10^{-7}$ cm$^3$/s for the type II \\ce{Na} MOT within an $\\approx 1070$ K ion cloud. Our measurements show excellent agreement with previously reported theoretical fully quantal \\textit{ab initio} calculations. In the process of determining the total rate coefficient, we demonstrate that a MOT can be used to probe an optically dark ion cloud's spatial distribution within a hybrid trap.

    We describe the design, construction, and operation of a versatile dual-species Zeeman slower for both Cs and Yb, which is easily adaptable for use with other alkali metals and alkaline earths. With the aid of analytic models and numerical simulation of decelerator action, we highlight several real-world problems affecting the performance of a slower and discuss effective solutions. To capture Yb into a magneto-optical trap (MOT), we use the broad 1S0 to 1P1 transition at 399 nm for the slower and the narrow 1S0 to 3P1 intercombination line at 556 nm for the MOT. The Cs MOT and slower both use the D2 line (62S1/2 to 62P3/2) at 852 nm. The slower can be switched between loading Yb or Cs in under 0.1 s. We demonstrate that within a few seconds the Zeeman slower loads more than 109 Yb atoms and 108 Cs atoms into their respective MOTs. These are ideal starting numbers for further experiments on ultracold mixtures and molecules.

With the aid of analytic models and numerical simulation of decelerator action, we highlight several real-world problems affecting the performance of a slower and discuss effective solutions. To capture Yb into a magneto-optical trap (MOT), we use the broad $^1S_0$ to $^1P_1$ transition at 399 nm for the slower and the narrow $^1S_0$ to $^3P_1$ intercombination line at 556 nm for the MOT. The Cs MOT and slower both use the D2 line ($6^2S_{1/2}$ to $6^2P_{3/2}$) at 852 nm. We demonstrate that within a few seconds the Zeeman slower loads more than $10^9$ Yb atoms and $10^8$ Cs atoms into their respective MOTs. These are ideal starting numbers for further experiments on ultracold mixtures and molecules.

  18. Zeeman-Sisyphus Deceleration of Molecular Beams

    Science.gov (United States)

    Fitch, Noah; Tarbutt, Mike

    2016-05-01

    Ultracold molecules are useful for testing fundamental physics and studying strongly-interacting quantum systems. One production method is via direct laser cooling in a magneto-optical trap (MOT). In this endeavor, one major challenge is to produce molecules below the MOT capture velocity. Established molecular beam deceleration techniques are poorly suited because they decelerate only a small fraction of a typical molecular pulse. Direct laser cooling is a natural choice, but is also problematic due to transverse heating and the associated molecule loss. I will present a new technique that we are developing, which we call Zeeman-Sisyphus deceleration and which shows great promise for preparing molecular beams for MOT loading. This technique decelerates molecules using a linear array of permanent magnets, along with lasers that periodically optically pump molecules between weak and strong-field seeking quantum states. Being time-independent, this method is well-suited for temporally extended molecular beams. Simultaneous deceleration and transverse guiding makes this approach attractive as an alternative to direct laser cooling. I will present our development of the Zeeman-Sisyphus decelerator and its application to a molecular MOT of CaF and an ultracold fountain of YbF.

    Roy, Basudev [Indian Institute of Science Education and Research, Kolkata (India); University of Maryland, MD (United States); Scholten, Michael [University of Maryland, MD (United States)

    2012-08-15

    This paper presents a setup capable of producing a high-flux continuous beam of cold rubidium atoms for cavity quantum electrodynamics experiments in the region of strong coupling. A 2D{sup +} magneto-optical trap (MOT), loaded with rubidium getters in a dry-film-coated vapor cell, fed a secondary moving-molasses MOT (MM-MOT) at a rate greater than 2 x 10{sup 10} atoms/s. The MM-MOT provided a continuous beam with a tunable velocity. This beam was then directed through the waist of a cavity with a length of 280 μm, resulting in a vacuum Rabi splitting of more than ±10 MHz. The presence of a sufficient number of atoms in the cavity mode also enabled splitting in the polarization perpendicular to the input. The cavity was in the strong coupling region, with an atom-photon dipole coupling coefficient g of 7 MHz, a cavity mode decay rate κ of 3 MHz, and a spontaneous emission decay rate γ of 6 MHz.

    2015-05-01

    The magneto-optical trap (MOT) is the workhorse technique for atomic physics in the ultracold regime, serving as the starting point in applications from optical clocks to quantum-degenerate gases. Recently, our group demonstrated the first magneto-optical trap for a molecule, strontium monofluoride (SrF). Here, we present experimental results of two variant trapping schemes which improve upon the original work. In the first, recent insights into the origin of the restoring force in Type-II MOTs (rarely used for atoms but requisite for SrF and other candidate molecules) led to a simple change in polarization scheme for the MOT lasers. In the second, states dark to the restoring MOT beams are diabatically transferred to bright states by synchronously reversing the magnetic field gradient and the laser polarization at RF frequencies. Although magneto-optical trapping of diatomic molecules is in its infancy, our results indicate that access to the ultracold regime may be possible for several molecular species, with potential applications from quantum simulation to tests of fundamental symmetries to ultracold chemistry. We acknowledge funding from ARO and ARO (MURI). E.B.N. acknowledges funding from the NSF GRFP.

  2. On the static loop modes in the marching-on-in-time solution of the time-domain electric field integral equation

    KAUST Repository

    2014-01-01

    When marching-on-in-time (MOT) method is applied to solve the time-domain electric field integral equation, spurious internal resonant and static loop modes are always observed in the solution. The internal resonant modes have recently been studied by the authors; this letter investigates the static loop modes. Like internal resonant modes, static loop modes, in theory, should not be observed in the MOT solution since they do not satisfy the zero initial conditions; their appearance is attributed to numerical errors. It is discussed in this letter that the dependence of spurious static loop modes on numerical errors is substantially different from that of spurious internal resonant modes. More specifically, when Rao-Wilton-Glisson functions and Lagrange interpolation functions are used as spatial and temporal basis functions, respectively, errors due to space-time discretization have no discernible impact on spurious static loop modes. Numerical experiments indeed support this discussion and demonstrate that the numerical errors due to the approximate solution of the MOT matrix system have dominant impact on spurious static loop modes in the MOT solution. © 2014 IEEE.

  8. A Highly Stable Marching-on-in-Time Volume Integral Equation Solver for Analyzing Transient Wave Interactions on High-Contrast Scatterers

    2014-01-06

    Time domain integral equation (TDIE) solvers represent an attractive alternative to finite difference (FDTD) and finite element (FEM) schemes for analyzing transient electromagnetic interactions on composite scatterers. Current induced on a scatterer, in response to a transient incident field, generates a scattered field. First, the scattered field is expressed as a spatio-temporal convolution of the current and the Green function of the background medium. Then, a TDIE is obtained by enforcing boundary conditions and/or fundamental field relations. TDIEs are often solved for the unknown current using marching on-in-time (MOT) schemes. MOT-TDIE solvers expand the current using local spatio-temporal basis functions. Inserting this expansion into the TDIE and testing the resulting equation in space and time yields a lower triangular system of equations (termed MOT system), which can be solved by marching in time for the coefficients of the current expansion. Stability of the MOT scheme often depends on how accurately the spatio-temporal convolution of the current and the Green function is discretized. In this work, band-limited prolate-based interpolation functions are used as temporal bases in expanding the current and discretizing the spatio-temporal convolution. Unfortunately, these functions are two sided, i.e., they require ”future” current samples for interpolation, resulting in a non-causal MOT system. To alleviate the effect of non-causality and restore the ability to march in time, an extrapolation scheme can be used to estimate the future values of the currents from their past values. Here, an accurate, stable and band-limited extrapolation scheme is developed for this purpose. This extrapolation scheme uses complex exponents, rather than commonly used harmonics, so that propagating and decaying mode fields inside the dielectric scatterers are accurately modeled. The resulting MOT scheme is applied to solving the time domain volume integral equation (VIE

    To relate the cognitive parameters of systemic lupus erythematosus (SLE) patients in remission to their profile of autoantibodies. The study included 32 patients with SLE in remission, with mild disease activity as indicated by SELENA-SLEDAI Cambridge Neuropsychological Test Automated Battery (CANTAB) was applied, using motor screening (MOT), big little circle (BLC), paired associated learning (PAL), stockings of Cambridge (SOC), and graded naming tests (GNT). Detection of autoantibodies against dsDNA, nucleosome (aNuc), Sm, and anticardiolipin (aCL: IgG and IgM) was performed with immunoassays. The SLE patients demonstrated standard scores below norms, matched according to age and gender, in the following tests: GNT (-0.87 ±0.85), SOC PSMM (-0.47 ±0.97), PAL (-1.88 ±3.58), and BLC (-0.31 ±1.90). GNT scores under -0.5 were found significantly more frequently in SLE patients, seen in roughly 66% of test subjects. Values for PAL and mean subsequent thinking time of stockings of Cambridge (SOC MSTT) were found to be lower than -0.5 in approximately half of the patients. Mean error of motor screening (MOT ME) was found to negatively correlate with mean latency of motor screening (MOT ML) (r = -0.55). PAL significantly correlated with SOC MSTT (r = 0.38) and with GNT (r = 0.36). Anti-dsDNA antibody level correlated negatively with MOT ME (r = -0.46). Anti-Nuc antibodies correlated with MOT ML (r = 0.41) but negatively correlated with MOT ME (r = -0.58). The levels of anti-Sm, anti-CL IgM and IgG did not correlate significantly with the outcomes of CANTAB. The age of the patients correlated negatively with MOT ME (r = -0.36), positively with BLC (r = 0.53) and negatively with SOC MSTT (r = -0.43). The level of anti-Nuc antibodies correlated with anti-dsDNA level (r = 0.62) and of anti-CL IgM with anti-Sm (r = 0.39) and anti-CL IgG (r = 0.87). CANTAB reveals a decrease in selected cognitive functions in patients with SLE. ACL IgG and anti-dsDNA antibodies indicated

    Effects of material nonlinearities on electromagnetic field interactions become dominant as field amplitudes increase. A typical example is observed in plasmonics, where highly localized fields “activate” Kerr nonlinearities. Naturally, time domain solvers are the method of choice when it comes simulating these nonlinear effects. Oftentimes, finite difference time domain (FDTD) method is used for this purpose. This is simply due to the fact that explicitness of the FDTD renders the implementation easier and the material nonlinearity can be easily accounted for using an auxiliary differential equation (J.H. Green and A. Taflove, Opt. Express, 14(18), 8305-8310, 2006). On the other hand, explicit marching on-in-time (MOT)-based time domain integral equation (TDIE) solvers have never been used for the same purpose even though they offer several advantages over FDTD (E. Michielssen, et al., ECCOMAS CFD, The Netherlands, Sep. 5-8, 2006). This is because explicit MOT solvers have never been stabilized until not so long ago. Recently an explicit but stable MOT scheme has been proposed for solving the time domain surface magnetic field integral equation (H.A. Ulku, et al., IEEE Trans. Antennas Propag., 61(8), 4120-4131, 2013) and later it has been extended for the time domain volume electric field integral equation (TDVEFIE) (S. B. Sayed, et al., Pr. Electromagn. Res. S., 378, Stockholm, 2013). This explicit MOT scheme uses predictor-corrector updates together with successive over relaxation during time marching to stabilize the solution even when time step is as large as in the implicit counterpart. In this work, an explicit MOT-TDVEFIE solver is proposed for analyzing electromagnetic wave interactions on scatterers exhibiting Kerr nonlinearity. Nonlinearity is accounted for using the constitutive relation between the electric field intensity and flux density. Then, this relation and the TDVEFIE are discretized together by expanding the intensity and flux - sing half

En effet, la mémoire sémantique devient déficitaire avec l'avancée de la démence. Son examen devrait permettre de mettre en avant la difficulté d'accès à cette mémoire en rendant prioritairement accessibles les mots faciles à récupérer, à savoir les mots fréquents et acquis tôt. Pour ce faire, nous avons soumis nos sujets à deux tâches de fluence verbale : une sémantique (animaux et l’autre littérale (P.

Une analyse de régression logistique indique que de ces deux facteurs, seul l'âge d'acquisition permet de prédire l'appartenance d'un sujet au groupe des patients Alzheimer.

    The goal of this study was to investigate how cognitive factors influence performance in a multi-talker, “cocktail-party” like environment in musicians and non-musicians. This was achieved by relating performance in a spatial hearing task to cognitive processing abilities assessed using measures of executive function (EF) and visual attention in musicians and non-musicians. For the spatial hearing task, a speech target was presented simultaneously with two intelligible speech maskers that were either colocated with the target (0° azimuth) or were symmetrically separated from the target in azimuth (at ±15°). EF assessment included measures of cognitive flexibility, inhibition control and auditory working memory. Selective attention was assessed in the visual domain using a multiple object tracking task (MOT). For the MOT task, the observers were required to track target dots (n = 1,2,3,4,5) in the presence of interfering distractor dots. Musicians performed significantly better than non-musicians in the spatial hearing task. For the EF measures, musicians showed better performance on measures of auditory working memory compared to non-musicians. Furthermore, across all individuals, a significant correlation was observed between performance on the spatial hearing task and measures of auditory working memory. This result suggests that individual differences in performance in a cocktail party-like environment may depend in part on cognitive factors such as auditory working memory. Performance in the MOT task did not differ between groups. However, across all individuals, a significant correlation was found between performance in the MOT and spatial hearing tasks. A stepwise multiple regression analysis revealed that musicianship and performance on the MOT task significantly predicted performance on the spatial hearing task. Overall, these findings confirm the relationship between musicianship and cognitive factors including domain-general selective attention and

    2016-01-01

    Objective: Real-time functional magnetic resonance imaging (rt-fMRI) neurofeedback (NF) uses feedback of the patient’s own brain activity to self-regulate brain networks which in turn could lead to a change in behavior and clinical symptoms. The objective was to determine the effect of NF and motor training (MOT) alone on motor and non-motor functions in Parkinson’s Disease (PD) in a 10-week small Phase I randomized controlled trial. Methods: Thirty patients with Parkinson’s disease (PD; Hoehn and Yahr I-III) and no significant comorbidity took part in the trial with random allocation to two groups. Group 1 (NF: 15 patients) received rt-fMRI-NF with MOT. Group 2 (MOT: 15 patients) received MOT alone. The primary outcome measure was the Movement Disorder Society—Unified PD Rating Scale-Motor scale (MDS-UPDRS-MS), administered pre- and post-intervention “off-medication”. The secondary outcome measures were the “on-medication” MDS-UPDRS, the PD Questionnaire-39, and quantitative motor assessments after 4 and 10 weeks. Results: Patients in the NF group were able to upregulate activity in the supplementary motor area (SMA) by using motor imagery. They improved by an average of 4.5 points on the MDS-UPDRS-MS in the “off-medication” state (95% confidence interval: −2.5 to −6.6), whereas the MOT group improved only by 1.9 points (95% confidence interval +3.2 to −6.8). The improvement in the intervention group meets the minimal clinically important difference which is also on par with other non-invasive therapies such as repetitive Transcranial Magnetic Stimulation (rTMS). However, the improvement did not differ significantly between the groups. No adverse events were reported in either group. Interpretation: This Phase I study suggests that NF combined with MOT is safe and improves motor symptoms immediately after treatment, but larger trials are needed to explore its superiority over active control conditions.

    Full Text Available Abstract Background To determine the effects of inferior alveolar nerve transection (IAN-X on masticatory movements in freely moving rats and to test if microglial cells in the trigeminal principal sensory nucleus (prV or motor nucleus (motV may be involved in modulation of mastication, the effects of microglial cell inhibitor minocycline (MC on masticatory jaw movements, microglia (Iba1 immunohistochemistry and the masticatory jaw movements and related masticatory muscle EMG activities were studied in IAN-X rats. Results The number of Iba1-immunoreactive (IR cells both in prV and motV was significantly larger in IAN-X rats compared with sham rats on day 3 after IAN-X. The intraperitoneal (i.p. administration of MC caused a significant reduction of the number of Iba1-IR cells both in prV and motV that was evident on day 14 after IAN-X. Furthermore, a significant reduction of the number of Iba1-IR cells could be observed in motV but not in prV after microinjection (m.i. of MC into the motV of IAN-X rats. The rats also exhibited a significant decrease in the head-withdrawal threshold on the side ipsilateral to the IAN-X compared to the threshold before IAN-X and it lasted to day 14. In addition, IAN-X markedly affected the ability to rat to carry out mastication. The number of complete masticatory sequences was significantly decreased. Furthermore, the total masticatory sequence time and food preparatory (PP period duration was significantly elongated in compared to sham rats. Although IAN-X significantly affected the total number of chewing cycles within the RC period of a masticatory sequence, it had no effect on the duration of the chewing cycles. On the other hand, systemic administration of MC (both i.p. and m.i. in IAN-X rats significantly improved decreased head-withdrawal threshold and the impaired masticatory jaw movements. Conclusions The present findings reveal that the strong modulation of masticatory jaw movements occurs following

  17. Explicit solution of Calderon preconditioned time domain integral equations

    Ulku, Huseyin Arda

    2013-07-01

    An explicit marching on-in-time (MOT) scheme for solving Calderon-preconditioned time domain integral equations is proposed. The scheme uses Rao-Wilton-Glisson and Buffa-Christiansen functions to discretize the domain and range of the integral operators and a PE(CE)m type linear multistep to march on in time. Unlike its implicit counterpart, the proposed explicit solver requires the solution of an MOT system with a Gram matrix that is sparse and well-conditioned independent of the time step size. Numerical results demonstrate that the explicit solver maintains its accuracy and stability even when the time step size is chosen as large as that typically used by an implicit solver. © 2013 IEEE.

The atom number enhancement was mainly due to the increased beam capture volume, afforded by the large area (4cm^2) shallow etch (200nm) binary grating chips. Here we provide a detailed theoretical and experimental investigation of the on-chip magneto-optical trap temperature and density in four different chip geometries using 87Rb, whilst studying effects due to MOT radiation pressure imbalance. With optimal initial MOTs on two of the chips we obtain both large atom number (2x10^7) _and_ sub-Doppler temperatures (50uK) after optical molasses.

    We present the results from two experiments investigating collisions that differ in time scale by three orders of magnitude. The first experiment enables the determination of absolute total collision cross sections using a technique that measures a change in the loss rate of trapped atoms from a magneto optical trap (MOT). We also investigate light assisted collision processes between cold metastable neon atoms in the {sup 3}P{sub 2} metastable state within the MOT. A catalysis laser is scanned in frequency across the {sup 3}P{sub 2} - {sup 3}D{sub 3} cooling transition and the ionization rate was observed. Ionization spectra are obtained which demonstrate a dependence on the magnetic sublevels of the transition that the catalysis laser is exciting.

    Atom interferometers have a multitude of proposed applications in space including precise measurements of the Earth's gravitational field, in navigation & ranging, and in fundamental physics such as tests of the weak equivalence principle (WEP) and gravitational wave detection. While atom interferometers are realized routinely in ground-based laboratories, current efforts aim at the development of a space compatible design optimized with respect to dimensions, weight, power consumption, mechanical robustness and radiation hardness. In this paper, we present a design of a high-sensitivity differential dual species $^{85}$Rb/$^{87}$Rb atom interferometer for space, including physics package, laser system, electronics and software. The physics package comprises the atom source consisting of dispensers and a 2D magneto-optical trap (MOT), the science chamber with a 3D-MOT, a magnetic trap based on an atom chip and an optical dipole trap (ODT) used for Bose-Einstein condensate (BEC) creation and interferometry...

    2016-01-01

    We describe a dynamic magneto-optical trap (MOT) suitable for the use with vacuum systems in which optical access is limited to a single window. This technique facilitates the long-standing desire of producing integrated atom chips, many of which are likely to have severely restricted optical access compared with conventional vacuum chambers. This "switching-MOT" relies on the synchronized pulsing of optical and magnetic fields at audio frequencies. The trap's beam geometry is obtained using a planar mirror surface, and does not require a patterned substrate or bulky optics inside the vacuum chamber. Central to the design is a novel magnetic field geometry that requires no external quadrupole or bias coils which leads toward a very compact system. We have implemented the trap for $^{85}$Rb and shown that it is capable of capturing 2 million atoms and directly cooling below the Doppler temperature.

    A novel and simple method to realize polarization gradient cooling(PGC)is reported.The stabilizing,shifting and rapid tuning of the frequency of the external cavity diode laser is realized by using the Zeeman-effect-assisted Doppler-free saturated absorption technique.Based on this convenient technique,~(87)Rb cold atoms are captured from room-temperature background vapor in the magneto-optical trap(MOT).Meanwhile,the steady-state number,the density and the lifetime of atoms in the MOT are measured.Subsequently,a frequency-fast-varying circuit is designed to realize PGC,which is demonstrated effectively and reliably in experiments.The temperature of the cold atom cloud is measured by two different methods,which coincide with each other.

    We demonstrate launching of laser-cooled Yb atoms in a continuous atomic fountain. The continuous fountain has significant advantages over the more common pulsed fountain, which was also demonstrated by us recently. The fountain is formed in the following steps---(i) Atoms from a thermal beam are first Zeeman slowed to a small final velocity, (ii) the slowed atoms are captured in a two-dimensional magneto-optic trap (2D-MOT), and (iii) atoms are launched {\\em continuously} in the vertical direction using two sets of moving-molasses beams, inclined at $\\pm 15^\\circ$ to the vertical. The cooling transition used is the strongly-allowed ${^1S}_0 \\rightarrow {^1P}_1$ transition at 399 nm. We capture about $7 \\times 10^6$ atoms in the 2D-MOT, and then launch them with a vertical velocity of 13 m/s at a longitudinal temperature of 125(6) mK.

    We present a compact source of cold sodium atoms suitable for the production of quantum degenerate gases and versatile for a multi-species experiment. The magnetic field produced by permanent magnets allows to simultaneously realize a Zeeman slower and a two-dimensional magneto-optical trap (MOT) within an order of magnitude smaller length than standard sodium sources. We achieve an atomic flux exceeding 4 × 109 atoms/s loaded in a MOT, with a most probable longitudinal velocity of 20 m/s, and a brightness larger than 2.5 × 1012 atoms/s/sr. This atomic source allows us to produce pure Bose-Einstein condensates with more than 107 atoms and a background pressure limited lifetime of 5 min.

    The magneto-optical trap (MOT) has long been the workhorse for atomic physics and is a powerful technique to rapidly produce ultracold, dense samples of atoms. Extending this technique to produce cold, dense samples of a diverse set of molecules will revolutionize the study of strongly interacting quantum systems, precision measurement and physical chemistry. In this work, we will report on progress towards the realization of a 3 dimensional MOT for the polar molecule YO. We are implementing a chirped frequency laser slowing scheme, where the buffer gas cooled molecules are slowed to a trappable velocity of 10 m/s. The 3D trapping is generated with a quasi-cycling transition and an oscillating quadrupole magnetic field. Current affiliation: Joint Quantum Institute, NIST and University of Maryland.

    Cold and ultracold molecules offer a wide array of possibilities for precision measurement, molecular quantum chemistry, and studies many-body physics. Recently, cold beams of many molecular species have been created via cryogenic buffer gas cooling. Paired with laser cooling, this method can yield a molecular magneto-optical trap (MOT). We report progress toward a barium monohydride (BaH) cold molecular beam and MOT, including identification of cooling transitions in the B2 Σ molecules and construction of the cryogenic beam apparatus. The large mass ratio of the constituent atoms makes this system attractive for studies of ultracold fragmentation via coherent transfer to weakly bound states and subsequent photo- or magneto-dissociation, resulting in ultracold hydrogen.

    Cryogenic buffer-gas beam (CBGB) sources are now routinely used to create slow atomic and molecular beams. While atoms from a CBGB can be loaded directly into a magneto-optical trap (MOT) without any Zeeman slower, additional slowing stages are required to load molecules due to their lower capture velocity (molecules using laser light at 606 nm in combination with two vibrational repumpers at 548 nm and 628 nm. The slowing lasers are broadened to cover the source's velocity spread and to remain resonant while molecules are being slowed. Our approach for slowing is similar to those for SrF and YO. Since CaF requires remixing of the magnetic sub-states to keep it in the optical cycle, we additionally implement an alternating-current (AC) MOT for trapping.

    We have successfully implemented the first simultaneous magneto-optical trapping (MOT) of lithium ($^6$Li) and ytterbium ($^{174}$Yb) atoms, towards production of ultracold polar molecules of LiYb. For this purpose, we developed the dual atomic oven which contains both atomic species as an atom source and successfully observed the spectra of the Li and Yb atoms in the atomic beams from the dual atomic oven. We constructed the vacuum chamber including the glass cell with the windows made of zinc selenium (ZnSe) for the CO$_2$ lasers, which are the useful light sources of optical trapping for evaporative and sympathetic cooling. Typical atom numbers and temperatures in the compressed MOT are 7$\\times10^3$ atoms, 640 $\\mu$K for $^6$Li, 7$\\times10^4$ atoms and 60 $\\mu$K for $^{174}$Yb, respectively.

  12. Adaptive mixture observation models for multiple object tracking

    Multiple object tracking (MOT) poses many difficulties to conventional well-studied single object track-ing (SOT) algorithms, such as severe expansion of configuration space, high complexity of motion con-ditions, and visual ambiguities among nearby targets, among which the visual ambiguity problem is the central challenge. In this paper, we address this problem by embedding adaptive mixture observation models (AMOM) into a mixture tracker which is implemented in Particle Filter framework. In AMOM, the extracted multiple features for appearance description are combined according to their discriminative power between ambiguity prone objects, where the discriminability of features are evaluated by online entropy-based feature selection techniques. The induction of AMOM can help to surmount the Incapa-bility of conventional mixture tracker in handling object occlusions, and meanwhile retain its merits of flexibility and high efficiency. The final experiments show significant improvement in MOT scenarios compared with other methods.

  13. Effects of moment of inertia on simple reaction time.

    Two experiments examined the effect of altering the moment of inertia within an anatomical unit on simple reaction time (SRT), premotor time (PMT), and motor time (MOT) during the initiation of a discrete rapid movement. In Experiment 1 (N = 14), moment of inertia of the forearm was increased with the addition of a weighted cuff fastened around the wrist. In Experiment 2 (N = 7), moment of inertia was altered by the addition of a weighted sleeve to the index finger prior to rapid extension of the digit. Results from both experiments were unequivocal. An increase in the moment of inertia resulted in a significant increase in SRT and MOT but had no significant effect on PMT. Within selected anatomical unites (forearm and index finger), an increase in the moment of inertia does not appear to require additional neuromotor programming time but does influence the overall duration of response initiation.

    The atmospheric composition inside spacecraft is dynamic due to changes in crew metabolism and payload operations. A portable FTIR gas analyzer was used to monitor the atmospheric composition of four modules (Core lab, Veggie Plant Atrium, Hygiene module, and Xhab loft) within the Deep Space Habitat '(DSH) during the Mission Operations Test (MOT) conducted at the Johnson Space Center. The FTIR was either physically relocated to a new location or the plumbing was changed so that a different location was monitored. An application composed of 20 gases was used and the FTIR was zeroed using N2 gas every time it was relocated. The procedures developed for operating the FTIR were successful as all data was collected and the FTIR worked during the entire MOT mission. Not all the 20 gases in the application sampled were detected and it was possible to measure dynamic VOC concentrations in each DSH location.

    We report a cost-effective way to prepare high-flux slow ytterbium atoms with extremely low-power 399-nm light suitable for the production of quantum degenerate ytterbium gases. By collimating an atomic beam through an array of micro-capillary tubes, we obtain a bright atomic beam through the Zeeman slower operating at low light power of only 15 mW for the source. We achieve the loading rate of 2 × 107 s-1 into the intercombination magneto-optical trap (MOT) and a sufficient steady-state MOT atom number of 2 × 108 for 174Yb atoms. Our apparatus highlights an efficient method to obtain slow ytterbium atoms using a simple low-power 399-nm laser system.

    A single atom in a magneto–optical trap (MOT) with trap size (hundreds of micrometers) can be transferred into an optical microscopic tweezer with a probability of∼100%. The ability to transfer a single atom into two traps back and forth allows us to study the loading process. The loading probability is found to be insensitive to the geometric overlap of the MOT and the tweezer. It is therefore possible to perform simultaneously loading of a single atom into all sites of the tweezer array for many qubits. In particular, we present a simulation of the one-dimensional and two-dimensional arrays of an optical microscopic tweezer. We find the same qualitative behavior for all of the trap parameters.

    2009-07-14

    Mounting evidence suggests that visual attention may be simultaneously deployed to multiple distinct object locations, but the constraints upon this multi-object attentional system are still debated. Results from multiple object tracking (MOT) experiments have been interpreted as revealing a fixed attentional capacity limit of 4 objects, while other evidence has suggested that attentional capacity may be more fluid. Here, we investigated the influence of target stimulus factors, such as speed and size, and of distractor filtering factors, such as number of distractors and screen density, on MOT performance. Each factor had significant effects on capacity, producing values that ranged from above 6 objects down to one object, depending on the task demands. Although our results support the view that crowding effects modulate the effective capacity of attention, we also find evidence that central processes related to distractor suppression and target enhancement modulate capacity.

    The Main Optical Telescope (MOT) is an important payload of the Space Solar Telescope (SST) with various instruments and observation modes. Its real-time data handling and management and control tasks are arduous. Based on the advanced techniques of foreign countries, an improved structure of onboard data handling systems feasible for SST, is proposed. This article concentrated on the development of a Central Management & Control Unit (MCU) based on FPGA and DSP. Through reconfigurating the FPGA and DSP programs, the prototype could perform different tasks.Thus the inheritability of the whole system is improved. The completed dual-channel prototype proves that the system meets all requirements of the MOT. Its high reliability and safety features also meet the requirements under harsh conditions such as mine detection.

    Nombre de journalistes patriotes, au début de la Révolution française, multiplient les remarques sur les nouveaux usages de la langue politique, certes pour en déplorer les abus – c’est le fameux thème au XVIIIe siècle d’« abus de mots » –, mais aussi pour s’interroger sur leur « signification précise ». Ces remarqueurs de la langue s’inscrivent dans une tradition linguistique ancienne, mais apportent, dans leur multiple « observation sur les mots » (Duquesnoy), des éléments précieux pour la ...

    Companies are traditionally facing constant challenges in prioritization and management of technology between short and long term. Competing technologies, market demands, supplier push, scarcity of resources, adequacy of skills, and shifting management priorities all affect potential outcome...... of well planned technological changes. Management of technology (MOT) addresses identification, selection, (long term) planning, designing, implementation and operation of technology based business development. Information Technology (IT) is a key enabler for a vast range of contemporary corporate...... technologies. In management of IT, it has become increasingly popular to use Enterprise Architecture (EA) as a method and supported by a series of formal frameworks. EA maps artifacts and motives against the business strategy. In this paper, MOT and EA are reviewed for their mutual potentials and issues. Two...

  15. Transient analysis of electromagnetic wave interactions on high-contrast scatterers using volume electric field integral equation

    2014-07-01

    A marching on-in-time (MOT)-based time domain volume electric field integral equation (TD-VEFIE) solver is proposed for accurate and stable analysis of electromagnetic wave interactions on high-contrast scatterers. The stability is achieved using band-limited but two-sided (non-causal) temporal interpolation functions and an extrapolation scheme to cast the time marching into a causal form. The extrapolation scheme is designed to be highly accurate for oscillating and exponentially decaying fields, hence it accurately captures the physical behavior of the resonant modes that are excited inside the dielectric scatterer. Numerical results demonstrate that the resulting MOT scheme maintains its stability as the number of resonant modes increases with the contrast of the scatterer.

  16. On the internal resonant modes in marching-on-in-time solution of the time domain electric field integral equation

    Internal resonant modes are always observed in the marching-on-in-time (MOT) solution of the time domain electric field integral equation (EFIE), although \\'relaxed initial conditions,\\' which are enforced at the beginning of time marching, should in theory prevent these spurious modes from appearing. It has been conjectured that, numerical errors built up during time marching establish the necessary initial conditions and induce the internal resonant modes. However, this conjecture has never been proved by systematic numerical experiments. Our numerical results in this communication demonstrate that, the internal resonant modes\\' amplitudes are indeed dictated by the numerical errors. Additionally, it is shown that in a few cases, the internal resonant modes can be made \\'invisible\\' by significantly suppressing the numerical errors. These tests prove the conjecture that the internal resonant modes are induced by numerical errors when the time domain EFIE is solved by the MOT method. © 2013 IEEE.

  17. Parallel, explicit, and PWTD-enhanced time domain volume integral equation solver

    Time domain volume integral equations (TDVIEs) are useful for analyzing transient scattering from inhomogeneous dielectric objects in applications as varied as photonics, optoelectronics, and bioelectromagnetics. TDVIEs typically are solved by implicit marching-on-in-time (MOT) schemes [N. T. Gres et al., Radio Sci., 36, 379-386, 2001], requiring the solution of a system of equations at each and every time step. To reduce the computational cost associated with such schemes, [A. Al-Jarro et al., IEEE Trans. Antennas Propagat., 60, 5203-5215, 2012] introduced an explicit MOT-TDVIE method that uses a predictor-corrector technique to stably update field values throughout the scatterer. By leveraging memory-efficient nodal spatial discretization and scalable parallelization schemes [A. Al-Jarro et al., in 28th Int. Rev. Progress Appl. Computat. Electromagn., 2012], this solver has been successfully applied to the analysis of scattering phenomena involving 0.5 million spatial unknowns. © 2013 IEEE.

  18. A Bacillus flagellar motor that can use both Na+ and K+ as a coupling ion is converted by a single mutation to use only Na+.

    Directory of Open Access Journals (Sweden)

    Full Text Available In bacteria, the sodium ion (Na(+ cycle plays a critical role in negotiating the challenges of an extremely alkaline and sodium-rich environment. Alkaliphilic bacteria that grow optimally at high pH values use Na(+ for solute uptake and flagellar rotation because the proton (H(+ motive force is insufficient for use at extremely alkaline pH. Only three types of electrically driven rotary motors exist in nature: the F-type ATPase, the V-type ATPase, and the bacterial flagellar motor. Until now, only H(+ and Na(+ have been reported as coupling ions for these motors. Here, we report that the alkaliphilic bacterium Bacillus alcalophilus Vedder 1934 can grow not only under a Na(+-rich and potassium ion (K(+-poor condition but also under the opposite condition in an extremely alkaline environment. In this organism, swimming performance depends on concentrations of Na(+, K(+ or Rb(+. In the absence of Na(+, swimming behavior is clearly K(+- dependent. This pattern was confirmed in swimming assays of stator-less Bacillus subtilis and Escherichia coli mutants expressing MotPS from B. alcalophilus (BA-MotPS. Furthermore, a single mutation in BA-MotS was identified that converted the naturally bi-functional BA-MotPS to stators that cannot use K(+ or Rb(+. This is the first report that describes a flagellar motor that can use K(+ and Rb(+ as coupling ions. The finding will affect the understanding of the operating principles of flagellar motors and the molecular mechanisms of ion selectivity, the field of the evolution of environmental changes and stresses, and areas of nanotechnology.
