description: We present a double precision routine in Fortran for the precise and fast numerical evaluation of the two Master Integrals (MIs) of the equal mass two-loop sunrise graph for arbitrary momentum transfer in d=2 and d=4 dimensions. The routine implements the accelerated power series expansions obtained by solving the corresponding differential equations for the MIs at their singular points. With a maximum of 22 terms for the worst case expansion a relative precision of better than a part in 10^{15} is achieved for arbitrary real values of the momentum transfer.

description: The Fuchs-Peres-Brandt (FPB) probe realizes the most powerful individual attack on Bennett-Brassard 1984 quantum key distribution (BB84 QKD) by means of a single controlled-NOT (CNOT) gate. This paper describes a complete physical simulation of the FPB-probe attack on polarization-based BB84 QKD using a deterministic CNOT constructed from single-photon two-qubit quantum logic. Adding polarization-preserving quantum nondemolition measurements of photon number to this configuration converts the physical simulation into a true deterministic realization of the FPB attack.

description: The iron, arsenic and chromium redox equilibrium in an oxide glass-forming melt has been studied quantitatively The equilibrium constant K(T) and the thermodynamic Standard values were determined for the redox reaction in the melt at temperatures between 1000 and 1450 °C. These values were compared with values from the literature. The equilibrium constant is dependent on the temperature and on the concentration of the polyvalent elements. This dependence applies to the polyvalent elements investigated. For each polyvalent element it is possible to find a step in the funcdon lg([R^y]/[R^x) versus R_aO_b- This seems to be explained by the concentradon dependence of the equilibrium constant of the redox reaction. Possibilities to determine the equilibrium constants of the various polyvalent elements are described.

description: Context. The characterisation of exoplanet atmospheres has shown a wide diversity in compositions. Hot Jupiters have the appropriate temperatures to host metallic compounds, which should be detectable through transmission spectroscopy. Aims. We aim to detect exotic species in transmission spectra of hot Jupiters, specifically WASP-31b, by testing a variety of chemical species to explain the spectrum. Methods. We conduct a re-analysis of publicly available transmission data of WASP-31b using the Bayesian retrieval framework TauREx II. We retrieve various combinations of the opacities of 25 species to determine the minimum set needed to fit the observed spectrum. Results. We report evidence for the spectroscopic signatures of chromium hydride (CrH), H2O and K in WASP-31b. Compared to a flat model without any signatures, a CrH-only model is preferred with a statistical significance of ~3.9 sigma. A model consisting of both CrH+H2O is found with ~2.6 sigma and ~3 sigma confidence over a CrH-only and H2O-only model respectively. Weak evidence for the addition of K is found at ~2.2 sigma over the H2O+CrH model, although the fidelity of the data point associated with this signature was questioned in earlier studies. Finally, the inclusion of collision-induced absorption and a Rayleigh scattering slope is found with ~3.5 sigma confidence over a flat model. This analysis presents the first evidence for signatures of CrH in a hot Jupiter atmosphere. At a retrieved temperature of ~1481 K, the atmosphere of WASP-31b is hot enough to host gaseous Cr-bearing species. The retrieved abundances agree well with predictions from thermal equilibrium chemistry and with the abundance found in an L-type brown dwarf atmosphere. However, additional retrievals using VLT FORS2 data lead to a non-detection of CrH. Future coverage with JWST has the potential to confirm the detection and discover other CrH features.

How does Vaccinia virus inhibit the detection of cytosolic DNA by the innate Immune system?
Creators: name: Dowling, Aaron
Publisher: name: Lancaster University
Year: 2018

description: Vaccinia virus (VacV) is a large dsDNA virus belonging to the Poxviridae family. Due to its size, the VacV replication cycle occurs entirely within the cytoplasm of infected cells. This exposes the virus to the many intracellular DNA sensors found in human cells. Since its discovery in 2013, cyclic GMP-AMP Synthase (cGAS) has been shown to be the predominant cytoplasmic DNA sensor in many cell types, including keratinocytes. Once activated, cGAS generates the second messenger cGAMP to trigger IFNβ production, through the adaptor protein STING. VacV can limit IFN production by inhibiting this pathway at multiple points, but little is known about whether VacV is able to inhibit DNA sensing directly. To investigate this, intracellular DNA sensing within keratinocytes was analysed during VacV infection. Results showed that within 4 hours of infection VacV was able to induce the loss of cGAS to undetectable levels, effectively blocking the cell IFNβ response. Additional DNA sensors that cooperate with cGAS such as IFI16 remained unaffected, showing that cGAS is essential for the IFN response to VacV. Inhibition of host degradation pathways did not prevent cGAS loss during VacV infection, suggesting cGAS is directly targeted for enzymatic cleavage. This demonstrates a potential new mechanism VacV employs to limit DNA sensing through cGAS, although the viral proteins responsible remain elusive. Identification of these proteins may provide new treatments for certain autoimmune disease where overactivation of cGAS contributes to disease phenotype.

description: During the forming process of a glass melt the viscosity is the dominant process parameter. Up to now in the industrial Container glass production only temperature-controlled Systems have been used. With these control elements only thermally induced variations of the viscosity are visible. Variations in the composition, the redox State , the water and the SO₃ content in the melting process cause a shift in the viscosity Up to now these changes have not been detectable and therefore, it has not been possible to compensate them. Α measuring device for t he continuous determinadon of the viscosity in the glass was developed and tested for several months in a Container glass plant. All measured variations of the viscosity can now be corrected by the existing control elements for the thermally controlled glass conditioning. Dependent on the posidon of the viscosimeter in the feeder Channel , a feedforward or feedback Controlling concept is practicable.

Influence of non-homologous substitutions of chemical components on rheological properties and on isochomal workability of Silicate glass melts

Year: 1996

description: The glass melts of a non-homologous series were investigated with respect to flow behaviour and stress generadon behaviour as well as to workability by means of the cylinder compression method. The results show that the competition between the gross viscosity effect and the bonding strength of the dynamic glass melt structure extremely deterrnines the high-temperature tensile strength, σ_ts, the critical deformation rate hc, and by that the isochomal workability. The larger hc values are not always connected to a larger non-Newtonian flow effect or to a larger gross viscosity effect as it is usually the case for homologous series. However, the rule for homologous series that smaller Emax moduli, i.e. smaller stiffness and brittleness of a glass melt, are coupled to a better isochomal workability is also vahd for non-homologous series. The special connections between σ_ts, hc and deformation, Δh/h0, are analyzed.

description: Ionization is a fundamental process in intense laser-matter interactions, and is known to cause plasma defocusing and intensity clamping. Here, we investigate theoretically the propagation dynamics of an intense laser pulse in a helium gas jet in the ionization saturation regime, and we find that the pulse undergoes self-focusing and self-compression through ionization-induced reshaping, resulting in a manyfold increase in the laser intensity. This unconventional behavior is associated with the spatiotemporal frequency variation mediated by ionization and spatiotempral coupling. Our results illustrate a new regime of pulse propagation and open up an optics-less approach for raising the laser intensity.

The crystalline template buffer layer is in-situ PLD grown through the step of high temperature stripping of the intrinsic silicon surface oxide. The X-ray diffraction pattern shows c-axis orientation of YSZ and b-axis orientation of GaFeO3 on Si (100) substrate. The ferromagnetic transition temperature (TC ~ 215 K) is in good agreement with the bulk data. The films show a large nonlinear second harmonic Kerr rotation of ~15 degrees in the ferromagnetic state.

description: Α new incremental procedure is developed for the thermal analysis in 3D glass products considering the one-dimensional analytical solutions for a semi-infmite glass wall. When coupled to a code being capable of computing large mechanical deformations, this allows to analyze efficiently the glass flow during the pressing, self-deformation and blowing processes. The forming of a reference tumbler is analyzed via finite element simulations. For each forming step, the temperature distribution is calculated from the pressing parameters; pertinent results are found for this first application.
Computer vision system for head movement detection and tracking
Creators: name: Lavergne, Anne
Publisher: name: University of British Columbia
Year: 2009

description: The increased popularity of applications requiring head tracking, such as teleconferencing and virtual reality, have fuelled research efforts to provide computer vision solutions to the problem of real-time head movement tracking. The attractiveness of this type of solution rests on the fact that head tracking can be performed without the use of expensive and cumbersome physical devices. We propose a computer vision approach that detects the head movements of a user seated at a computer workstation. We model head translation and head rotation using distinct sets of templates synthesized from an initially captured image of the head and representing this head in various positions (and sizes) and orientations. Using correlation-based template matching, we achieve detection by correlating these sets of templates against each image of the head captured by a camera positioned on the top of the monitor. The best-correlating template from the set modelling head translation and the best from the set modelling head rotation represent good approximations of the three-dimensional position and orientation of the head in the scene, respectively. We improve on these approximations by defining two functions that interpolate the correlation scores of each set and by obtaining the minimum of each of these functions. We use these two minima, which represent head position and orientation, to synthesize a new template based on the initially captured image of the head. This new synthesized template represents the image of the head that most closely approximates the head position and orientation in the scene. Head movement tracking is performed by comparing the closest approximation of the head found in two consecutive images of the scene. We have implemented our head movement tracking approach and found our system to track head position, on average, to within one pixel of the measured head position in both the x- and y-axis directions, and to detect head size (width and height), on average, to within one and two pixels of the measured head width and height, respectively. Our head movement tracking system tracks head rotations, on average, to within 1.4° of the measured angles.. Our tracker is capable of processing up to eight captured images per second.

description: The need for improved traffic estimation procedures has been emphasized by several studies that demonstrated that previously available data were not adequate. Some data were not considered representative of actual traffic conditions because of overloaded trucks avoiding weighing scales and insufficient traffic sampling programs. In addition, previous forecasting procedures did not reflect the increases in legal load limits, the significant increase in the number of heavy trucks, or the shift toward larger vehicle types that has occurred in recent years.  Improved estimates of current traffic loadings based on larger samples of much higher quality data would allow development of procedures for making improved estimates of historical traffic loadings and better forecasts of traffic loadings during the design period. The emergence of automatic vehicle classification equipment, permanent and portable weigh-in-motion (WIM) systems, and the application of microprocessors and microcomputers to these data acquisition functions now offer tools that may be used effectively in meeting these needs.  Representatives from four States (Florida, Kentucky, Oregon, and Washington) met on several occasions to discuss the subject of traffic forecasting for pavement design. Information was compiled on all aspects of the traffic forecasting process, options were presented for each step of the process, and recommendations were developed to assist highway agencies in improving current practices and procedures.

description: The objective of this investigation was to analyze glass formation and crystaUization in t h e SiO₂ - Li₂O- ZrO₂ - P₂O₅ System for the development of high-strength glass-ceramics produced with glass powder. In the course of this study, it was found that the base glass or the semicrystalline glass-ceramic could be pressed to form glass-ceramic final products. The analysis of glass formation demonstrated that in a relatively large composition range, up to almost 30 wt%, ZrO₂ could be incorporated into the base glass and increased the glass forming tendency. Other additives were also tested. The presence of ZrO₂ crystals, ZrSiO₄ crystals and lithium phosphate crystals as well as other secondary phases in t he microstructure following heat treatment at approximately 1000 °C was estabhshed in SEM and XRD examinations. This glass-ceramic possesses fiexural strengths of 280 MPa. Translucency was observed in 0.5 mm thick layers. Growth rates of the main crystal phases were determined with cast monolithic samples in a semiquantitative kinetic evaluation of phase development. In contrast to the kinetics of mica crystal growth processes in machinable glass-ceramics, no time lags were observed.

description: In this work, we study the three-dimensional non-Abelian noncommutative supersymmetric Chern-Simons model with the U(N) gauge group. Using a superfield formulation, we prove that, for the pure gauge theory, the Green functions are one-loop finite in any gauge, if the gauge superpotential belongs to the fundamental representation of $u(N)$; this result also holds when matter in the fundamental representation is included. However, the cancellation of both ultraviolet and ultraviolet/infrared infrared divergences only happens in a special gauge if the coupling of the matter is in the adjoint representation. We also look into the finite one-loop quantum corrections to the effective action: in the pure gauge sector the Maxwell together with its corresponding gauge fixing action are generated; in the matter sector, the Chern-Simons term is generated, inducing a shift in the classical Chern-Simons coefficient.

description: The quantum spin Hall (QSH) state is a topologically non-trivial state of quantum matter which preserves time-reversal symmetry; it has an energy gap in the bulk, but topologically robust gapless states at the edge. Recently, this novel effect has been predicted and observed in HgTe quantum wells. In this work we predict a similar effect arising in Type-II semiconductor quantum wells made from InAs/GaSb/AlSb. Because of a rare band alignment the quantum well band structure exhibits an "inverted" phase similar to CdTe/HgTe quantum wells, which is a QSH state when the Fermi level lies inside the gap. Due to the asymmetric structure of this quantum well, the effects of inversion symmetry breaking and inter-layer charge transfer are essential. By standard self-consistent calculations, we show that the QSH state persists when these corrections are included, and a quantum phase transition between the normal insulator and the QSH phase can be electrically tuned by the gate voltage.

description: The exponential increase in the use of the Internet and social media over the last two decades has changed human interaction. This has led to many positive outcomes, but at the same time it has brought risks and harms. While the volume of harmful content online, such as hate speech, is not manageable by humans, interest in the academic community to investigate automated means for hate speech detection has increased. In this study, we analyse six publicly available datasets by combining them into a single homogeneous dataset and classify them into three classes, abusive, hateful or neither. We create a baseline model and we improve model performance scores using various optimisation techniques. After attaining a competitive performance score, we create a tool which identifies and scores a page with effective metric in near-real time and uses the same as feedback to re-train our model. We prove the competitive performance of our multilingual model on two langauges, English and Hindi, leading to comparable or superior performance to most monolingual models.

Epitaxial heterostructures of half-metal colossal magnetoresistive La2/3Ca1/3MnO3 (HM-CMR) and high Tc superconducting YBa2Cu3O7 (YBCO) are grown on SrTiO3 (100) single crystal substrates by pulsed laser deposition. Using the HM--CMR layer as source for spin-polarized quasiparticles, we show the effect of injection of spin-polarized quasiparticles into the ab-plane and along the c-axis of YBCO. The results show a drop in the ab-plane resistance Rab (T) in the case of injection along the c-axis that is discussed to be related to the opening of a pseudogap.

The flux declines with a power law slope of alpha = -0.57 between the start of observations some 230 seconds after the burst onset (90s after the burst trigger) until it faded below the sensitivity threshold of the instrument after ~5 x 10^4s. There is no evidence for the rapidly declining component in the early light curve that is seen at the same time in the X-ray band. The afterglow is not detected in UVOT shortward of the B-band, suggesting a redshift of about 3.5. The optical V-band emission lies on the extension of the X-ray spectrum, with an optical to X-ray slope of beta = -0.8. The relatively flat decay rate of the burst suggests that the central engine continues to inject energy into the fireball for as long as a few x 10^4s after the burst.

description: Redox interacdons between the Fe²⁺-Fe³⁺ and Mn²⁺-Mn³⁺ redox couples and the Fe²⁺-Fe³⁺ and Cr⁶⁺-Cr³⁺ redox couples were spectrophotometrically determined in soda lime Silicate compositions quenched from different melting temperatures (1100 to 1400°C) at air. Both Mn³⁺ and Cr⁶⁺ stoichiometrically oxidized Fe²⁺. Thus, for example in the iron-manganese System, the color of the glass was determined by Fe³⁺ and Mn²⁺ along with either Fe²⁺ o r Μn²⁺, whichever one being in excess at that temperature. The electron exchange between the redox couples occurred during equilibration at melt temperature and not as an artifact of the quench. No evidence was obtained for a rapid internal re-equilibrium of redox states with decreasing temperature during the normal cooling of a melt to a glass. The degree of redox interaction of manganese or chromium with iron is independent of the manganese or chromium Compound added, as long as the oxygen fugacity over the glass-forming melt is held constant externally.

description: The effect of doping Mo for Mn on the magnetic and transport properties of the colossal magnetoresistance material, La0.67Ba0.33MnO3, has been studied. Compounds of the series La0.67Ba0.33Mn1-xMoxO3 (x=0.0 to 0.1) have been prepared and found to crystallize in the orthorhombic structure (space group Pbnm). Energy Dispersive X-ray Analysis (EDAX) measurements confirm the stoichiometry of all the samples. Magnetotransport and magnetization measurements reveal that the metal-insulator transition temperature (Tp) decreases from 330K for x=0 to 255K for x=0.1. The change in Tp on Mo substitution is relatively much smaller than the corresponding change observed on substitution by other transition elements, such as Ti, Fe, Co, Ni, etc. Further, the ferromagnetic transition temperature (TC) is nearly unchanged by Mo substitution. This is in striking contrast to the large decrease in TC observed with substitution of above-mentioned 3d elements. These unusual magnetic and transport properties of La0.67Ba0.33Mn1-xMoxO3 may be either due to the formation of magnetic pair between Mn and Mo or due to strong Mo(4d)-O(2p) overlap, which in turn, may affect the Mn-Mn interaction via the oxygen atoms

description: Reversible logic gates were previously implemented in superconducting circuits as adiabatic-reversible gates, which are powered with a sufficiently slow clock. In contrast, we are studying ballistic-reversible gates, where fluxons serve to both encode the information and power the gates. No power is applied to the gate apart from the energy of the input fluxons, and the two possible flux polarities represent the bit states. Undamped long Josephson junctions (LJJs), where fluxons move at practically constant speed from inertia, form the input and output channels of the gates. LJJs are connected in the gates by circuit interfaces, which are designed to allow the ballistic scattering from input to output fluxon states, using the temporary excitation of a localized mode. The duration of the resonant scattering determines the operation time of the gate, approximately a few Josephson plasma periods. Due to the coherent conversions between fluxon and localized modes the ballistic gates can be very efficient: in our simulations only a few percent of the fluxon's energy are dissipated in the gate operation. Ballistic-reversible gates can be combined with other, non-ballistic gate circuits to extend the range of gate functionalities. Here we describe how the CNOT can be built as a structure that includes the IDSN (Identity-else-Same-gives-NOT) and Store-and-Launch (SNL) gates. The IDSN is a 2-bit ballistic gate, which we describe and analyze in terms of equivalent 1-bit circuits. The SNL is a clocking gate, that allows the storage of a bit and the clocked launch of a fluxon on a bit-state dependent output path. In the CNOT the SNL gates provide the necessary routing and fluxon synchronization for the input to the IDSN gate.

description: We present a first catalogue of X-ray sources resulting from the central area of the XMM-LSS (Large Scale Structure survey). We describe the reduction procedures and the database tools we developed and used to derive a well defined catalogue of X-ray sources. The present catalogue is limited to a sub-sample of 286 sources detected at 4 sigma in the 1 deg^2 area covered by the photometric VVDS (VIRMOS VLT Deep Survey), which allows us to provide optical and radio identifications. We also discuss the X-ray properties of a larger X-ray sample of 536 sources detected at > 4 sigma in the full 3 deg^2 area of the XMM Medium Deep Survey (XMDS) independently of the optical identification. We also derive the logN-logS relationship for a sample of more than one thousand sources that we discuss in the context of other surveys at similar fluxes.

description: The recently developed energy-scale-dependent Composite Operator Method is applied to the single-impurity Anderson model. A fully self-consistent solution is given and analyzed. At very low temperatures, the density of states presents, on the top of the high-energy background, a Kondo-like peak whose parameter dependence is discussed in detail. The proposed method reproduces the exact results known in the literature with very low numerical effort and it is applicable for arbitrary values of the external parameters.

Rheological properties and isochomal workability of lead Silicate glass melts

description: Four different industrial lead Silicate glass melts were investigated by means of the cylinder compression method with respect to the flow and stress generation behaviour, the critical deformation rate hc, and the high-temperature tensile strength, σ_ts. Increasing PbO concentration has usually a large influence on t he Newtonian viscosity, it makes the melt "shorter" (more modernly speaking: more "fragile"). On the other hand, the influence on the non-Newtonian flow and stress generation behaviour and therefore, on the brittleness is very small, however, the high-temperature tensile strength is markedly negatively influenced. At low viscosities the melts with large P bO content show larger critical deformation rates and therefore, a better isochomal workability than those with smaller P bO contents. As compared with soda lime Silicate glass melts the lead Silicate melts reach clearly smaller hc and σ_ts values at comparable degrees of deformation and therefore, they have a worse isochomal workability This unexpected behaviour is discussed under structural aspects.
Thermal technologies to convert solid waste residuals into technical glass products

description: Solid waste residuals f r o m waste incinerator flue gas cleaning Systems consist of various oxides, alkali halogenide salts, heavy metal Compounds and traces of organic pollutants. After the Separation of the volatile components from the oxides and the complete destruction of the organics by a thermal treatment at a temperature υ > 1200°C, the remaining oxides are obtained as a homogeneous black glass ready for the direct reuse as a filling or stabilizing material, the production of glass-ceramics by a further thermal processing and/or the use as a secondary raw material for the production of technical glass products, e.g. glass wool, glass fibre or foam glass. For the determination of the reuse potential of the vitrified wastes, basic material parameters have to be determined and compared with Standard glasses. Under this aspect the chemical resistance in acids, bases and water, the density, the hardness, the elasticity, shear and compression moduli, the Poisson's ratio, the bending strength, the dielectric permittivity a nd losses, the refractive index, the optical reflectivity and absorption behaviour, the thermal expansion coefficient, the thermal conductivity and heat capacity were determined for vitrified electrostatic precipitator ash from municipal solid waste incineration plants. The results of these studies, compared with those obtained for Duran, showed a low leachability in neutral and alkaline media a nd good electrical, mechanical and thermal properties. Tests to transform the as-received glasses into glass-ceramics were carried out. Preliminary recrystallization experiments led to dark brown to black-coloured, partially recrystallized glass samples.

description: The withdrawal of a liquid or the translation of a liquid slug in a capillary tube leads to the deposition of a thin film on the inner wall. When particles or contaminants are present in the liquid, they deposit and contaminate the tube if the liquid film is sufficiently thick. In this article, we experimentally investigate the condition under which particles are deposited during the air invasion in a capillary tube initially filled with a dilute suspension. We show that the entrainment of particles in the film is controlled by the ratio of the particle and the tube radii and the capillary number associated with the front velocity. We also develop a model which suggests optimal operating conditions to avoid contamination during withdrawal of a suspension. This deposition mechanism can also be leveraged in coating processes by controlling the deposition of particles on the inner walls of channels.
