description: Decoy states have been proven to be a very useful method for significantly enhancing the performance of quantum key distribution systems with practical light sources. While active modulation of the intensity of the laser pulses is an effective way of preparing decoy states in principle, in practice passive preparation might be desirable in some scenarios. Typical passive schemes involve parametric down-conversion. More recently, it has been shown that phase randomized weak coherent pulses (WCP) can also be used for the same purpose [M. Curty {\it et al.}, Opt. Lett. {\bf 34}, 3238 (2009).] This proposal requires only linear optics together with a simple threshold photon detector, which shows the practical feasibility of the method. Most importantly, the resulting secret key rate is comparable to the one delivered by an active decoy state setup with an infinite number of decoy settings. In this paper we extend these results, now showing specifically the analysis for other practical scenarios with different light sources and photo-detectors. In particular, we consider sources emitting thermal states, phase randomized WCP, and strong coherent light in combination with several types of photo-detectors, like, for instance, threshold photon detectors, photon number resolving detectors, and classical photo-detectors. Our analysis includes as well the effect that detection inefficiencies and noise in the form of dark counts shown by current threshold detectors might have on the final secret ket rate. Moreover, we provide estimations on the effects that statistical fluctuations due to a finite data size can have in practical implementations.

title: Mechanistische Untersuchungen der Acroleinoxidation an Mischoxid- und Heteropolysäurekatalysatoren
Creators: name: Knoche, Stefan
Publisher: name: UNSPECIFIED
Year: 2022

description: Diese Dissertation befasst sich mit der Partial-Oxidation von Acrolein an Mo/V/W-Mischoxid- sowie Heteropolysäurekatalysatoren. Mit Hilfe transienter Methoden, insbesondere Isotopenaustauschmethoden (Acrolein --> D₆-Acrolein, hergestellt aus D₆-Propen; H₂O --> H₂¹⁸O; H₂O --> D₂O; ¹⁶O₂ --> ¹⁸O₂), wurde ein erweiterter Katalysemechanismus aufgestellt. Die kinetischen Modellierungen zeigen, dass der entwickelte Mechanismus quantitativ sowohl Umsatz- und Selektivitätsverläufe als auch entstehende Isotopenmuster beschreibt. Der Mechanismusvergleich der beiden Katalysatorsysteme zeigt viele Gemeinsamkeiten, aber auch entscheidende Unterschiede, die zu der unterschiedlichen Performance der Katalysatoren führen.

Mechanism of action of streptomycin : studies with polynucleotide phosphorylase and ribosomes
Creators: name: Willick, Gordon Edward
Publisher: name: University of British Columbia
Year: 2011

description: Some of the previous work on the mechanism of action of streptomycin has indicated the general area of nucleic acid metabolism as being a possible site of action. Specifically, a report has appeared that streptomycin inhibits the "exchange reaction" catalyzed by polynucleotide phosphorylase. Therefore, the possible action of streptomycin on polynucleotide phosphorylase from a streptomycin sensitive strain of Escherichia coli has been reinvestigated. In preparation for the study on polynucleotide phosphorylase, the nucleoside diphosphates of adenosine, guanosine, cytidine, and uridine were synthesized in sufficient yield and of a satisfactory purity by the recently developed method of Moffatt and Khorana. It was not possible to confirm the inhibition of the polynucleotide phosphorylase catalyzed "exchange reaction" reported by Kornberg, using enzyme from our streptomycin sensitive E. coli SA. Nor was it possible to demonstrate any inhibition of the polymerization reaction catalyzed by this enzyme, or any effect on the sedimentation properties of the polymer so formed. However, the diamines putrescine, cadaverine, spermine, and spermidine, while having no effect on the time course of the polymerization reaction, did lower the sedimentation coefficient of the polymer formed and cause a more heterogeneous polymer to be formed. Streptomycin has been suggested as an inhibitor of protein synthesis. Therefore, a study of the possible effects of streptomycin on ribosomes from E. coli was made. These subcellular particles have been shown to be a site of protein synthesis. Dihydrostreptomycin (DHSM) interacted strongly with the ribosomes. It was found that most of the ribonucleo-protein precipitated when ribosomes were dialyzed overnight at 4° against buffer containing about 500 μg./ml. of DHSM. A study of ultracentrifuge patterns of dialysates of ribosomes against lower levels of DHSM indicated that disruption, with a loss of discrete sedimentation coefficients, occurred when the level of DHSM was about 350 μg./ml. A study of elution patterns from DEAE-cellulose columns indicated only a partial change in the pattern after breakdown. Examination of sedimentation coefficients of ribosome dialysates at lower DHSM levels indicated no specific effect of DHSM. The autodegradation of ribosomes by polynucleotide phosphorylase was studied. DHSM, at low levels, had an effect on the time course of the auto-degradation. A study of the distribution of induced β-D-galactosidase associated with the ribosomes indicated that it was associated with that protein of the ribosomes not precipitated by DHSM. It can be concluded that streptomycin interacts strongly with ribosomes. This gives support to recent claims that streptomycin inhibits ‘in vitro' protein synthesis, and that the site of this inhibition is the ribosome.
Main phase transition in lipid bilayers: phase coexistence and line tension in a soft, solvent-free, coarse-grained model

Publisher: name: arXiv
Year: 2010
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: We devise a soft, solvent-free, coarse-grained model for lipid bilayer membranes. The non-bonded interactions take the form of a weighted-density functional which allows us to describe the thermodynamics of self-assembly and packing effects of the coarse-grained beads in terms of a density expansion of the equation of state and the weighting functions that regularize the microscopic bead densities, respectively. Identifying the length and energy scales via the bilayer thickness and the thermal energy scale, kT, the model qualitatively reproduces key characteristics (e.g., bending rigidity, area per lipid molecules, and compressibility) of lipid membranes. We employ this model to study the main phase transition between the liquid and the gel phase of the bilayer membrane. We accurately locate the phase coexistence using free energy calculations and also obtain estimates for the bare and the thermodynamic line tension.

description: A high resolution powder diffractometer connected to the wiggler magnet line BX1, is now operative at the Adone storage ring in Frascati. A Si channel-cut monochromator on the line allows operation in the range 1-3 A. To achieve the desired high resolution in the diffraction spectra, a 'triple-axis configuration' has been chosen: avertical standing \\theta/2\\theta goniometer supports a flat Ge(111) crystal analyzer on the 2\\theta arm. With this configuration, a value of less than 0.02' (degrees) for the FWHM of the diffraction peaks has been reached. The special design solutions adopted for a Seifert MZ VI goniometer and the microstep technology used in the stepper motor actuation assure a mechanical resolution better than 0.001' (degrees). A special supporting table, with six degrees of freedom, has been made for the diffractrometer orientation in front of the X-ray beam. An IBM-PC is dedicated to the diffractrometer positioning control and preliminary data collection. As a Macintosh IICX provides for the data processing, a special software package, named 'Mac Dust', has been developed and is continuosly updated. The first experimental results collected on-line during the instrument check-up are presented.

Year: 1992

description: We investigate a new lattice regularization of gauge theories where gauge-invariance with non compact gauge fields is realizated by the help of auxiliary fields. For the gauge group SU(2) there is only one auxiliary field. We construct the complete action for scaling dimension 2 of this field. In this case the regularization ammounts to relax unitarity of the Wilson link variables, but has the same renormalization scale parameter showing the stability of Wilson's fixed point.
The Sepulchre of the Priest John Blodwell in Holy Trinity Church, Balsham, Cambridgeshire d. 16th April 1462
Creators: name: Lamp, Reinhard
Publisher: name: Pegasus-Onlinezeitschrift
Year: 2021

description: It is natural for a friend of medieval Latin texts found on a brass epitaph to enjoy detecting a mistake in the engraving, as in the present case of the commemorative brass to John Blodwell in Balsham, Cambridgeshire, which even has three such events. It definitely makes the day for the specialist. In reality, however, it is unjust to gloat over a mistake. Mistakes are natural, are to be expected. On the contrary, each time an inscription is faultless, one should take off one’s hat to the engraver. In the Middle Ages only a small minority of the population was able to read and write, and an estimated 2 % only understood a Latin text and would know to evade errors when copying it. The meaning of an inscription was explained to the parishioners or visitors by the priest. So, one may consider an engraver to be a high-calibre expert and knowledgeable specialist of a metal-workshop, artisan and artist to boot, who not seldom went out of his way to deliver a graphic work of art, equipping a letter, in particular capitals, with manifold decorations, thus spending additional time and energy while finding his joy in creating a thing of beauty. In our present case, however, the engraver was inattentive and committed a thundering blunder, which caused havoc. The present author ventured to repair it by his conjecture. More interesting even is the rare event of the poet making a mistake in the Latin poem on purpose in order to get his message across. One example of such liberty taken with the language is found on the commemorative brass plate for Rupert of Jülich-Berg, bishop-elect of Paderborn. The marginal text describes him as De montis vectum bavarorum – meaning “Him who travelled here from the mountains of the Bavarians”, in order to explain that he resisted the chance of occupying the rich and powerful see of Passau, preferring to be bishop in his own duchy of Berg, in Westfalia. The Latin text should be understood as containing the elliptical terms “gens, or stirps, or familia” and to be read as De (gente) montis – “Of the family of Berg”, thus pointing to Rupert belonging to the ducal family of Berg. Insolent, but ingenious. Something similar happened on Blodwell’s foot-inscription. The poet wrote invenit, but that would not have made sense in its context. He intended the word to be understood as Invenitur, thus avoiding a mistake of prosody. In the same text occurs the word do in the meaning of deo. In both cases the relevant letters received a special treatment as a warning. Thus the inscriptions on Blodwell’s memorial are not only a work of graphic art, but also ensure high-rate entertainment in the act of deciphering them.

description: Several Wide Field of view Adaptive Optics (WFAO) concepts like Multi-Conjugate AO (MCAO), Multi-Object AO (MOAO) or Ground-Layer AO (GLAO) are currently studied for the next generation of Extremely Large Telescopes (ELTs). All these concepts will use atmospheric tomography to reconstruct the turbulent phase volume. In this paper, we explore different reconstruction algorithms and their fundamental limitations. We conduct this analysis in the Fourier domain. This approach allows us to derive simple analytical formulations for the different configurations, and brings a comprehensive view of WFAO limitations. We then investigate model and statistical errors and their impact on the phase reconstruction. Finally, we show some examples of different WFAO systems and their expected performance on a 42m telescope case.

description: The layered manganese oxides LnBaMn1.96Fe0.04Oy (Ln=Y, Gd, Sm, Nd, Pr, La) have been synthesized for y=5, 5.5 and 6. In the oxygen-saturated state (y=6) they exhibit the charge and orbital order at ambient temperature for Ln=Y, Gd, Sm, but unordered eg-electronic system for Ln=La,Pr,Nd. Fourfold increase of quadrupole splitting was observed owing to the charge and orbital ordering. This is in agreement with the jumplike increase in distortion of the reduced perovskite-like cell for the charge and orbitally ordered manganites compared to the unordered ones. Substitution of 2 percents of Mn by Fe suppresses the temperatures of structural and magnetic transitions by 20 to 50 K. Parameters of the crystal lattices and the room-temperature Mössbauer spectra were studied on forty samples whose structures were refined within five symmetry groups: P4/mmm, P4/nmm, Pm-3m, Icma and P2/m. Overwhelming majority of the Fe species are undifferentiated in the Mössbauer spectra for most of the samples. Such the single-component spectra in the two-site structures are explained by the preference of Fe towards the site of Mn(III) and by the segmentation of the charge and orbitally ordered domains.

We first characterize their effective linear spectrum both theoretically and experimentally. We then illustrate theoretically and numerically the modulational instability of the lower edge of the optical band. This leads to the dynamical formation of long-lived breather structures, whose families of solutions we compute throughout the linear spectral gap. Finally, we observe experimentally such localized breathing modes with quantitative characteristics that agree with our numerical results.

description: A comprehensive, calculated line list of frequencies and transition probabilities for the singly deuterated isotopologue of H3+, H2D+, is presented. The line list, called ST1, contains over 22 million rotational-vibrational transitions occurring between more than 33 thousand energy levels; it covers frequencies up to 18500 cm-1. All energy levels with rotational quantum number, J, up to 20 are considered, making the line list useful for temperatures up to at least 3000 K. About 15% of these levels are fully assigned with approximate rotational and vibrational quantum numbers. The list is calculated using a previously proposed, high accuracy, ab initio model and consistency checks are carried out to test and validate the results. These checks confirm the accuracy of the list. A temperature-dependent partition function, valid over a more extended temperature range than those previously published, and cooling function are presented. Temperature-dependent synthetic spectra in the frequency range 0 - 10000 cm-1 are also given.

Starting from a generalized Einstein--Maxwell action with nonzero cosmological constant, we examine all possible scalar invariants that can be formed from the complete set of Riemann invariants (up to order 10 in derivatives). The resulting entropies show the deviation from the well known Bekenstein--Hawking area law $S=A/4G$ for Einstein's gravity up to second order derivatives.

description: We report on the first results of an investigation on the eigenfrequencies and quality factors of vibration of Al 5056 spherical resonators at very low temperatures. In particular the characteristics of the lowest order spheroidal quadrupole mode, relevant for gravitational wave research, were measured. The resonators were suspended at the nodal point. Quality factors up to 1.2 108 were measured in a bulk sample down to 44 mK. Another spherical resonator was obtained by means of explosively-bonded stacks and showed a maximum quality factor of 2 107. The observed quadrupole modes appear to be split into frequency multiplets, because of the broken spherical symmetry, as theoretically predicted. The independence of the modes was measured within one part in 105 in amplitude.

description: We investigate theoretically the behavior of a one-dimensional interacting Bose-Fermi mixture with equal masses and equal repulsive interactions between atoms at finite temperature in the scheme of thermodynamic Bethe ansatz. Combining the Yang-Yang thermodynamic formalism with local-density approximation in a harmonic trap, we calculate the density distribution of bosons and fermions numerically by treating the radially and axially excited states as discrete and continuous ones, respectively. Our result from exactly solvable solutions may be used as a touchstone for one-dimensional interacting Bose-Fermi mixture for experimental data fitting where mean-field theoretical approaches fail.

description: The recent AGT suggestion to use the set of Nekrasov functions as a basis for a linear decomposition of generic conformal blocks works very well not only in the case of Virasoro symmetry, but also for conformal theories with extended chiral algebra. This is rather natural, because Nekrasov functions are introduced as expansion basis for generalized hypergeometric integrals, very similar to those which arise in expansion of Dotsenko-Fateev integrals in powers of alpha-parameters. Thus, the AGT conjecture is closely related to the old belief that conformal theory can be effectively described in the free field formalism, and it can actually be a key to clear formulating and proof this long-standing hypothesis. As an application of this kind of reasoning we use knowledge of the exact hypergeometric conformal block for complete proof of the AGT relation for a restricted class of external states.

description: The Baldin sum rule for the nucleon has been recalculated at the light of the most recent photoabsorption cross section measurements. The proton value (a+b)p=13.69±0.14 is smaller but consistent with the one usually quoted in literature. However, the value for the neutron (a+b)n=14.40±0.66 turns out to be three standard deviations away from the previously calculated one.

description: We present new empirical estimates of the Delta V_HB_bump parameter for 15 Galactic globular clusters (GGCs) using accurate and homogeneous ground-based optical data. Together with similar evaluations available in the literature, we ended up with a sample of 62 GGCs covering a very broad range in metal content (-2.16<=[M/H]<=-0.58 dex). Adopting the homogeneous metallicity scale provided either by Kraft & Ivans (2004) or by Carretta et al. (2009), we found that the observed Delta V_HB_bump parameters are larger than predicted. In the metal-poor regime ([M/H]<=-1.7, -1.6 dex) 40% of GCs show discrepancies of 2sigma (~0.40 mag) or more. Evolutionary models that account either for alpha- and CNO-enhancement or for helium enhancement do not alleviate the discrepancy between theory and observations. The outcome is the same if we use the new Solar heavy-element mixture. The comparison between alpha- and CNO-enhanced evolutionary models and observations in the Carretta et al. metallicity scale also indicates that observed Delta V_HB_bump parameters, in the metal-rich regime ([M/H]=>0), might be systematically smaller than predicted.
Aharonov-Bohm oscillations in disordered nanorings with quantum dots: Effect of electron-electron interactions

description: We investigate the effect of electron-electron interactions on Aharonov-Bohm (AB) current oscillations in nanorings formed by a chain of metallic quantum dots. We demonstrate that electron-electron interactions cause electron dephasing thereby suppressing the amplitude of AB oscillations at all temperatures down to T=0. The crossover between thermal and quantum dephasing is found to be controlled by the ring perimeter. Our predictions can be directly tested in future experiments.

What can we learn about protoplanetary disks from analysis of mid-infrared carbonaceous dust emission?

description: In this Paper we analyze the mid-infrared (mid-IR) emission of very small dust particles in a sample of 12 protoplanetary disks to see how they are connected to interstellar dust particles and to investigate the possibility that their emission can be used as a probe of the physical conditions and evolution of the disk. We define a basis made of three mid-IR template spectra PAH$^0$, PAH$^+$ and VSGs that were derived from the analysis of reflection nebulae, and an additional PAH$^x$ spectrum that was introduced by Joblin et al. (2008) for the analysis of the spectra of planetary nebulae. From the optimization of the fit of 12 star+disk spectra, using a linear combination of the 4 template spectra, we found that an additional small grain component with a broad feature at 8.3 $μ$m is needed. We find that the fraction of VSG emission in disks decreases with increasing stellar temperature. VSGs appear to be destroyed by UV photons at the surface of disks, thus releasing free PAH molecules, which are eventually ionized as it is observed in photodissociation regions. On the opposite, we observe that the fraction of PAH$^x$ increases with increasing star temperature except in the case of B stars where they are absent. We argue that this is compatible with the identification of PAH$^x$ as large ionized PAHs, most likely emitting in regions of the disk that are close to the star. Finally, we provide a UV-dependant scheme to explain the evolution of PAHs and VSGs in protoplanetary disks. We show that A stars modify the size spectrum of PAHs and VSGs in favor of large PAHs while B stars destroy even the largest PAHs up to large radii in the disk. These results allow us to put new constrains on the properties of two sources: IRS 48 and "Gomez's Hamburger" which are poorly characterized.

Manufacturing land productivity and land-use forecasting : as experienced by the petroleum refining industry of B.C.'s lower mainland
Creators: name: Fletcher, Roy Howard
Publisher: name: University of British Columbia
Year: 2011

description: Improved techniques for forecasting land needs for urban development are required with continuing population and economic growth for the provision of adequate services at reasonable cost. Current local forecasting techniques exclude the direct measurement of land used in industrial activities and its correlation with industrial production. With continuing technological improvements in industrial processes it is likely that the relation between land and output will vary and particularly in the manufacturing industries. A review of the Petroleum Refining Industry's experience by a direct mailed questionnaire to all Lower Mainland of B.C. refiners indicated a declining importance of land in relation to output over the last two decades. Trends in refinery output, employment, and land in active use, show an increasing productivity of both land and labor. The increase in productivity of manufacturing land exceeded that of labor over the past twenty years in this industry group. A conceptual comparison was made between two types of forecast where, in one, the factor of increasing output per unit of land was excluded. The comparison was inexact since somewhat different industries were compared. However, it appeared that over a twenty-year period the exclusion of the productivity of land factor in the example could lead to significantly different results. The difference between the techniques was an indicated requirement of 1200 acres versus 600 acres in total land needed up to 1980 by the industry group. Before the factor of land productivity in manufacturing and other industries can be adequately considered changes are required in the methods of collecting statistics. These changes would enable a correlation between output, employment, population, and land within the urban area.
How to Define Variation of Physical Properties Normal to an Undulating One-Dimensional Object

description: One-dimensional flexible objects are abundant in physics, from polymers to vortex lines to defect lines and many more. These objects structure their environment and it is natural to assume that the influence these objects exert on their environment depends on the distance from the line-object. But how should this be defined? We argue here that there is an intrinsic length scale along the undulating line that is a measure of its "stiffness" (i.e., orientational persistence), which yields a natural way of defining the variation of physical properties normal to the undulating line. We exemplify how this normal variation can be determined from a computer simulation for the case of a so-called bottle-brush polymer, where side chains are grafted onto a flexible backbone.

Publisher: name: INFN Open Access Repository
Year: 1999

description: We present updated results of the measurement of the atmospheric neutrino flux with the MACRO detector at Gran Sasso, using three data sets spread in a large energy range. In the high energy range, the upgoing throughgoing muon data set is in favor of νμ →ντ  oscillation hypothesis with a probability of 36.6% against the 0.36% for the no oscillation hypothesis.In the low energy range, the two data set are also in favor to the oscillation hypothesis showing a large defict for IU events and a reduced defict for US+ID events, since only the US events ( |50% ) are expected to oscillate Assuming a νμ →ντ  oscillation scheme, the results suggest a large range of the parameter values centered around Dm2=0.0025 eV2, sin2 2q = 1.

description: In this paper we study the behavior of solutions of a second order differential equation. The existence of a zero and its localization allow us to get some compactness results. In particular we obtain a Myers' type theorem even in the presence of an amount of negative curvature. The technique we use also applies to the study of spectral properties of Schroedinger operators on complete manifolds.

description: The solving of the Schrodinger equation for a position-dependent mass quantum system is studied in two ways. First, it is found the interaction which must be applied on a mass m(x) in order to supply it with a particular spectrum of energies. Second, given a specific potential V(x) acting on the mass m(x), the related spectrum is found. The method of solution is applied to a wide class of position-dependent mass oscillators and the corresponding coherent states are constructed. The analytical expressions of such position-dependent mass coherent states preserve the functional structure of the Glauber states.
