description: For a compact, connected, simply-connected Lie group G, the loop group LG is the infinite-dimensional Hilbert Lie group consisting of H^1-Sobolev maps S^1-->G. The geometry of LG and its homogeneous spaces is related to representation theory and has been extensively studied. The space of based loops Omega(G) is an example of a homogeneous space of $LG$ and has a natural Hamiltonian T x S^1 action, where T is the maximal torus of G. We study the moment map mu for this action, and in particular prove that its regular level sets are connected. This result is as an infinite-dimensional analogue of a theorem of Atiyah that states that the preimage of a moment map for a Hamiltonian torus action on a compact symplectic manifold is connected. In the finite-dimensional case, this connectivity result is used to prove that the image of the moment map for a compact Hamiltonian T-space is convex. Thus our theorem can also be viewed as a companion result to a theorem of Atiyah and Pressley, which states that the image mu(Omega(G)) is convex. We also show that for the energy functional E, which is the moment map for the S^1 rotation action, each non-empty preimage is connected.

description: Fluid flows play a central role in scientific and technological development, and many of these flows are characterized by a dominant oscillation, such as the vortex shedding in the wake of nearly all transportation vehicles. The ability to control vortex shedding is critical to improve the aerodynamic performance of these unsteady fluid flow systems. This goal requires precise characterization of how perturbations affect the long-time phase of the oscillatory flow, as well as the ability to control transient behaviors. In this work, we develop an energy-efficient flow control strategy to rapidly alter the oscillation phase of time-periodic fluid flows, leveraging theory developed for periodic biological systems. First, we perform a phase-sensitivity analysis to construct a reduced-order model for the response of the flow oscillation to impulsive control inputs at various phases. Next, we introduce two control strategies for real-time phase control based on the phase-sensitivity function: 1) optimal phase control, obtained by solving the Euler-Lagrange equations as a two-point boundary value problem, and 2) model-predictive control (MPC). Our approach is demonstrated for two unsteady flow systems, the incompressible laminar flow past a circular cylinder and the flow past an airfoil. We show that effective phase control may be achieved with several actuation strategies, including blowing and rotary control. Moreover, our control approach uses realistic measurements of the lift force on the body, rather than requiring high-dimensional measurements of the full flow field.

description: Livestock industries are significantly affected by changes in consumer behaviour. In order to add value to meat and livestock production, many firms and farms are supporting the development of new products – these products can differ by credence attribute, by degree of processing and by marketing strategies. The literature suggests that one of the most important determinants of success in product innovation is an understanding of the market the product is introduced into. In this report consumer preferences for meat products, by animal species including minor meats, and by type of processing are examined. Responses to economic variables such as price, advertising and income are identified as are responses to food safety and meat related health issues. Interesting results include the fact that income elasticities of demand for meat products purchased at grocery stores are negative in this study and that own and cross price elasticities for certain meats, across processing levels for example, show strong substitutions. Thus introducing new meat products may not result in increased sales by animal species but may only result in substitution of one meat type product for another product of the same meat type. Successful new product introductions or changes in product quality are shown, in this report, to be accompanied by significant marketing/advertising investment and, either by design or by serendipity, to have credence attributes in line with consumer's changing concerns. An example of this is the response in branded chicken sales, at the time of BSE in Canada, for a brand that could advertise itself as being 100% grain fed. Marketing strategies, such as working with the Health Check™ program of the Heart and Stroke Foundation of Canada are shown to have an impact on firm level sales (as well as on sales at the individual product level), a halo effect, that may be of importance in the firm's development of other value-added products. Significant heterogeneity exists in consumer behaviour and it is important to recognize this heterogeneity in the development of value-added meat products. Added to the consumer heterogeneity, in general, is the heterogeneity in responses by meat type. What works for one sector, such as poultry, could be problematic in other sectors given differences in economic interrelationships reported in this study.

description: We study the R-parity violating minimal supergravity models accounting for the observed neutrino masses and mixing, which can be tested in future collider experiments. The bi-large mixing can be explained by allowing five dominant tri-linear couplings $ λ'_{1,2,3}$ and $λ_{1,2}$. The desired ratio of the atmospheric and solar neutrino mass-squared differences can be obtained in a very limited parameter space where the tree-level contribution is tuned to be suppressed. In this allowed region, we quantify the correlation between the three neutrino mixing angles and the tri-linear R-parity violating couplings. Qualitatively, the relations $| λ'_1 | < | λ'_2| \sim | λ'_3|$, and $|λ_1| \sim |λ_2|$ are required by the large atmospheric neutrino mixing angle $θ_{23}$ and the small angle $θ_{13}$, and the large solar neutrino mixing angle $θ_{12}$, respectively. Such a prediction on the couplings can be tested in the next linear colliders by observing the branching ratios of the lightest supersymmetric particle (LSP). For the stau or the neutralino LSP, the ratio $|λ_1|^2: |λ_2|^2: |λ_1|^2 + |λ_2|^2$ can be measured by establishing $Br(eν): Br(μν) : Br(τν)$ or $Br(νe^\pm τ^\mp ): Br(νμ^\pmτ^\mp) : Br(ντ^\pmτ^\mp)$, respectively. The information on the couplings $λ'_i$ can be drawn by measuring $Br(l_i t \bar{b}) \propto |λ'_i|^2$ if the neutralino LSP is heavier than the top quark.

description: In this article, we present a novel Carleman estimate for ultrahyperbolic operators, in $ \mathbb{R}^m_t \times \mathbb{R}^n_x $. Then, we use a special case of this estimate to obtain improved observability results for wave equations with time-dependent lower order terms. The key improvements are: (1) we obtain smaller observation regions compared to standard Carleman estimate results, and (2) we also prove observability when the observation point lies inside the domain. Finally, as a corollary of the observability result, we obtain improved interior controllability for the wave equation.

description: Ship traffic has been increasing in the Canadian Arctic, and with it, underwater noise. Underwater noise from ships is known to cause a number of impacts on marine animals, and is therefore an important concern in the Arctic. This report is part of a larger study funded by the Nunavut General Monitoring Plan. In the report, we examine ship traffic in the Kitikmeot Region and Lancaster Sound, Nunavut (Northwest Passage – southern route), and model the noise levels caused by all of the ship traffic between 2015 and 2018. Ship noise peaks in August and September of every year analysed. Modeled ship noise was highest within Eclipse Sound due to the large volume of traffic within that area, but was also high south of Victoria Island in Dease Strait where ships are spatially constricted to following a relatively narrow route. Future work should be carried out to validate these modeling results with acoustic measurements in different parts of this region. Future work should also examine the overlap between ship noise and various marine animals, such as narwhal and beluga, to estimate the exposure of these animals to ship noise. ᐃᖅᑲᒃᑯᑦ. ᐃᖅᑲᒥ ᓂᐱᖏᑦ ᐅᒥᐊᕐᔪᐊᕐᓃᙶᖅᑐᑦ ᐃᒪᕐᒥᐅᑕᑦ ᐆᒪᔪᖏᖕᓂ ᐊᑦᑐᐃᓂᖃᓲᖑᖕᒪᑕ, ᐊᒻᒪᓗ ᑕᐃᒪᐃᒻᒪᑦ ᐱᒻᒪᕆᐅᔪᒃᑯᑦ ᐃᓱᒫᓘᑎᒋᔭᐅᕗᖅ ᐅᑭᐅᖅᑕᖅᑐᒥ. ᑖᓐᓇ ᐅᓂᒃᑳᖅ ᐃᓚᒋᔭᐅᕗᖅ ᐊᖏᓂᖅᓴᒥᒃ ᖃᐅᔨᓴᖅᑕᒥᓂᐅᔪᒧᑦ ᑮᓇᐅᔭᖃᖅᑎᑕᐅᔪᖅ ᓄᓇᕗᒻᒥ ᑕᒪᐃᓐᓄᑦ ᐅᐊᑦᑎᓂᕐᒧᑦ ᐸᕐᓇᐅᑎᖓᓂᒃ. ᐅᓂᒃᑳᕐᒥ, ᖃᐅᔨᓴᖅᐳᒍᑦ ᐅᒥᐊᕐᔪᐊᒃᑯᑦ ᐃᖏᕐᕋᖃᑦᑕᕐᓂᖏᑦ ᕿᑎᕐᒥᐅᒥ ᐊᒻᒪᓗ ᑕᓪᓗᕈᑎᑉ ᐃᒪᖓᓂ, ᓄᓇᕗ (ᐅᑭᐅᖅᑕᖅᑑᑉ ᓱᓪᓗᐊᓗᐊ − ᓂᒋᖅᐸᓯᖓᒍᑦ ᐊᖅᑯᑎᖓ), ᐊᒻᒪᓗ ᑖᒃᑯᐊ ᓂᐱᖏᑕ ᓴᙱᓂᖏᑦ ᐋᖅᑭᓱᖅᑕᐅᓗᑎᑦ ᖃᓄᑎᒋ ᓂᐱᖃᕐᒪᖔᑕ ᑕᒪᐃᓐᓂ ᐅᒥᐊᕐᔪᐊᒃᑯᑦ ᐃᖏᕐᕋᕙᑦᑐᒥᓃᑦ 2015 ᐊᒻᒪᓗ 2018 ᐊᑯᕐᖓᖓᓂ. ᐅᒥᐊᕐᔪᐊᒃᑯᑦ ᓂᐱᖃᕐᓂᖅᓴᐅᓕᓲᖅ ᐋᒡᒌᓯᒥ ᐊᒻᒪᓗ ᓯᑏᕝᕙ ᓂᐊᕐᕌᒍᑕᒫᑦ ᖃᐅᔨᓴᖅᑕᒥᓂᐅᔪᑦ ᒪᓕᑦᑐᒋᑦ. ᐆᑦᑐᕋᖅᑕᐅᓯᒪᔪᑦ ᐋᖅᑭᓱᖅᑕᐅᓯᒪᓪᓗᑎᑦ ᐅᒥᐊᕐᔪᐊᕐᒦᙶᖅᑐᑦ ᓂᐱᖏᑦ ᖁᑦᑎᓂᖅᐹᖑᓯᒪᕗᖅ ᑕᓯᐅᔭᕐᒥ ᐊᒥᓲᓂᖏᖕᓄᑦ ᐅᒥᐊᕐᔪᐊᑦ ᐃᖏᕐᕋᔪᑦ ᑕᐅᕘᓇ, ᑭᓯᐊᓂᓗ ᖁᑦᑎᓛᖑᓯᒪᒋᕗᑦ ᓂᒋᐊᓂ ᐃᖃᓗᒃᑑᑦᓯᐊᑉ ᕿᑭᖅᑕᓂᖓᑕ ᐅᒥᐊᕐᔪᐊᑦ ᐊᑕᐅᑦᑎᒨᕐᓂᖅᓴᐅᓲᖑᓪᓗᑎᑦ ᑐᐊᓗᐊᕐᓂᖓᓄᑦ ᐊᖅᑯᑎᖓ. ᓯᕗᓂᒃᓴᒥ ᐃᖅᑲᓇᐃᔮᕆᔭᐅᔭᕆᐊᓖᑦ ᑕᒪᒃᑯᐊ ᐋᖅᑭᓱᖅᑕᐅᓯᒪᙳᐊᖅᑐᑦ ᓇᓗᓇᐃᖅᑕᐅᖁᓪᓗᒋᑦ ᖃᐅᔨᓴᖅᑕᒥᓃᑦ ᖃᓄᑎᒋ ᓂᐱᖃᖅᑎᒋᒻᒪᖔᑕ ᐊᔾᔨᒌᙱᑦᑐᓂᑦ ᐊᕕᑦᑐᖅᓯᒪᔪᓂ. ᓯᕗᓂᒃᓴᒥᓗ ᐃᖅᑲᓇᐃᔮᕆᔭᐅᔭᕆᐊᖃᕆᕗᑦ ᖃᐅᔨᓴᕈᓐᓇᕋᔭᖅᑐᑎᑦ ᐅᒥᐊᕐᔪᐊᒦᙶᖅᑐᑦ ᓂᐱᖏᑦ ᐊᒻᒪᓗ ᐊᔾᔨᒌᙱᑦᑐᑦ ᐃᒪᕐᒥᐅᑕᐃᑦ ᐆᒪᔪᐃᑦ, ᓲᕐᓗᒃ ᑐᒑᓖᑦ ᐊᒻᒪᓗ ᕿᓚᓗᒐᐃᑦ, ᓇᓚᐅᑦᑖᖅᑕᐅᖁᓪᓗᒋᑦ ᑕᒪᒃᑯᐊ ᐆᒪᔪᑦ ᐅᒥᐊᕐᔪᐊᑉ ᓂᐱᖏᖕᓄᑦ ᐊᑦᑐᖅᑕᐅᓂᖃᓲᖑᖕᒪᖔᑕ ᖃᓄᑎᒋ.
Electronic and structural effects on the electrochemistry of polypyrrole
Creators: name: Warren, Mya
Publisher: name: University of British Columbia
Year: 2009

description: The electrochemical properties of polypyrrole are influenced by a complex interconnection of electronic, structural, and chemical properties of the polymer matrix. These properties were investigated individually in polypyrrole doped with the hexafluorophosphate ion in order to create a complete model of polypyrrole electrochemistry. The electronic conductivity of polypyrrole was investigated through D C conductivity measurements of films in varying oxidation states. The well-known doping induced metal-insulator transition was observed at an electrode potential of -0.1V versus standard calomel electrode (SCE). X-ray diffraction and macroscopic actuation measurements revealed that a structural change begins at the same potential, possibly due to a loss of pi-stacking in the polymer crystals. Electrochemical impedance spectroscopy was performed over a range of oxidation states, and showed that the impedance goes through a sudden transition at -0.1V as well, which is attributed to changes in ionic conductivity. The non-linear dependence of the electronic and ionic conductivity of polypyrrole with oxidation state were included in a finite difference time domain model which simulated potentiostatic charging and discharging of the polymer matrix. The modelv was able to explain the moving phase front phenomenon during charging of polypyrrole that has been observed in the literature. The front is a shock wave that occurs whenever the polymer is stepped from a state of low to high ionic or electronic conductivity. It also presents an explanation for the redox peaks observed in cyclic voltammograms that does not rely on the Nernst equation, and is therefore more consistent with the electronic nature of polypyrrole.

Os resultados favoreceram a localização abatedouros próximos aos integrados e de centros de distribuição próximos aos clientes, sujeitas às diversas restrições impostas pela realidade local.---------------------------------------------This work studied the localization of a poultry agro-industry and optimized its net, from the integrated to the consumers, determining the amount of frigorific and centers of distribution that the company must have and the localization of these to minimize costs. From the collection of real data and using Geographic Systems tools of Information and binary linear program, it was determined excellent configuration for the net as well as the configuration of diverse alternative scenes. The used objective function minimizes the total amount of the localization and the slaughterhouse costs, the localization costs of the distribution center, the production costs and remittance of the alive chicken from the integrated one until the slaughterhouse, the slaughter costs and remittance until the distribution center and the storage costs in the distribution center and remittance until the final customers. The excellent scene gotten considers only the installation of a slaughterhouse and a distribution center of bigger capacity, evidencing scale profits. The results favored the localization of the slaughterhouses close to the integrated ones and also the distribution centers close to the customers, subjected to the diverse restrictions imposed for the local reality.
Measurement of the muon decay asymmetry parameter with the TWIST spectrometer
Creators: name: Jamieson, Blair
Publisher: name: University of British Columbia
Year: 2010

description: Muon decay, a purely leptonic decay, is a relatively simple interaction to study when looking for physics not explained by the standard theory of electroweak interactions. In particular, the muon decay asymmetry parameter is directly related to the degree to which weak interactions violate parity, or mirror, symmetry. At the Tri-University Meson Facility (TRIUMF), the TRIUMF Weak Interaction Symmetry Test (TWTST) spectrometer was used to measure the energy and angle spectrum of decay positrons from muon decay. By measuring a large part of the muon decay spectrum, TWXST can simultaneously determine three of the muon decay parameters with a high degree of accuracy. This thesis presents the first direct TWIST measurement of the muon decay asymmetry parameter PM£ which was determined to be 1.0003 ±0.0006(stat) ±0.0038(syst). The uncertainty on this measurement is a factor of two lower than a previous direct measurement. This measurement is consistent with the standard model of particle physics, and further constrains physics beyond the standard model.

description: One of the open problems in the field of forward uncertainty quantification (UQ) is the ability to form accurate assessments of uncertainty having only incomplete information about the distribution of random inputs. Another challenge is to efficiently make use of limited training data for UQ predictions of complex engineering problems, particularly with high dimensional random parameters. We address these challenges by combining data-driven polynomial chaos expansions with a recently developed preconditioned sparse approximation approach for UQ problems. The first task in this two-step process is to employ the procedure developed in (Ahlfeld et al. 2016) to construct an "arbitrary" polynomial chaos expansion basis using a finite number of statistical moments of the random inputs. The second step is a novel procedure to effect sparse approximation via $\ell^1$ minimization in order to quantify the forward uncertainty. To enhance the performance of the preconditioned $\ell^1$ minimization problem, we sample from the so-called induced distribution, instead of using Monte Carlo (MC) sampling from the original, unknown probability measure. We demonstrate on test problems that induced sampling is a competitive and often better choice compared with sampling from asymptotically optimal measures (such as the equilibrium measure) when we have incomplete information about the distribution. We demonstrate the capacity of the proposed induced sampling algorithm via sparse representation with limited data on test functions, and on a Kirchoff plating bending problem with random Young's modulus.

description: Using self-consistent cosmological simulations of disc galaxy formation, we analyse the 1.4 GHz radio flux from high-redshift progenitors of present-day normal spirals within the context of present-day and planned next-generation observational facilities. We demonstrate that while current radio facilities such as the Very Large Array (VLA) are unlikely to trace these progenitors beyond redshifts z<0.2, future facilities such as the Square Kilometer Array (SKA) will readily probe their characteristics to redshifts z<2, and are likely to provide detections beyond z~3. We also demonstrate that the progenitors of present-day cD galaxies can emit in excess of 10 uJy of flux at redshifts z>1, and may be a non-negligible contributor to the micro-Jansky source counts derived from current deep VLA cm-wave surveys.

description: We present the result from a CHANDRA observation of an X-ray luminous starburst galaxy UGC 6697, which is embedded in the northwest hot region of A1367 (5 - 6 keV). A very sharp X-ray edge (~ 13 times of surface brightness jump) at the southeast and a long tail (at least 60 kpc from the nucleus) at the northwest of the galaxy are detected, as expected if the galaxy is moving to the southeast. The X-ray edge, at the midway of the nucleus and the southeast optical disk edge, is also at the same position where the Halpha emission is truncated and a radio sharp edge is observed. The X-ray diffuse emission is also enhanced at the southeast, implying ram pressure compression. No extraplanar X-ray component is detected, probably due to the combining effects of weaker outflow activity than that in nuclear starbursts, and external confinement plus stripping. The diffuse thermal gas in UGC 6697 has a temperature of ~ 0.7 keV and a low iron abundance (~0.1 - 0.2 solar). An X-ray point source (L (0.5-10 keV) ~ 2.8 x 10^{40} ergs s^{-1}) is detected on the nucleus, but not highly absorbed. Three off-center ultraluminous X-ray sources, all with L (0.5-10 keV) > 10^{40} ergs s^{-1}, are also detected. Based on the multi-wavelength data available, we favor that the interaction between the interstellar medium (ISM) and the ICM plays a major role to trigger the starburst in UGC 6697.

description: With the distance sum rule in the Friedmann-Lema\^ıtre-Robertson-Walker metric, model-independent constraints on both the Hubble constant $H_0$ and spatial curvature $Ω_{K}$ can be obtained using strong lensing time-delay data and Type Ia supernova (SN Ia) luminosity distances. This method is limited by the relative low redshifts of SNe Ia, however. Here, we propose using quasars as distance indicators, extending the coverage to encompass the redshift range of strong lensing systems. We provide a novel and improved method of determining $H_0$ and $Ω_{K}$ simultaneously. By applying this technique to the time-delay measurements of seven strong lensing systems and the known ultraviolet versus X-ray luminosity correlation of quasars, we constrain the possible values of both $H_0$ and $Ω_{K}$, and find that $H_0=75.3^{+3.0}_{-2.9}$ km $\rm s^{-1}$ $\rm Mpc^{-1}$ and $Ω_{K}=-0.01^{+0.18}_{-0.17}$. The measured $Ω_{K}$ is consistent with zero spatial curvature, indicating that there is no significant deviation from a flat universe. If we use flatness as a prior, we infer that $H_0=75.3^{+1.9}_{-1.9}$ km $\rm s^{-1}$ $\rm Mpc^{-1}$, representing a precision of 2.5\%. If we further combine these data with the 1048 current Pantheon SNe Ia, our model-independent constraints can be further improved to $H_0=75.3^{+3.0}_{-2.9}$ km $\rm s^{-1}$ $\rm Mpc^{-1}$ and $Ω_{K}=0.05^{+0.16}_{-0.14}$. In every case, we find that the Hubble constant measured with this technique is strongly consistent with the value ($\sim 74$ km $\rm s^{-1}$ $\rm Mpc^{-1}$) measured using the local distance ladder, as opposed to the value optimized by {\it Planck}.

description: We present high signal-to-noise echelle spectra of the compact high surface brightness, low ionization planetary nebula IC 418. These reveal 807 emission lines down to intensities less than 10$^{-5}$ that of H$β$ for which we determine widths and relative intensities. We show that line profiles are a valuable parameter for making line identifications and in constraining the excitation mechanism of the lines. We present evidence that indicates that many supposed high-level recombination lines may in fact be excited by a process other than recombination. We contend from the detection of dielectronic recombination lines that their relatively low intensities argue against their making a significant contribution to level populations of the heavy ions in this object. Following similar analyses of other PNe we find that IC 418 shows a small discrepancy in ion abundances derived from forbidden vs. recombination lines of the heavy elements.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Es wird diskutiert, dass die Zuckerzufuhr eine kausale Rolle in der Entwicklung von Typ 2 Diabetes (T2D) und subklinischer Entzündungsneigung spielt. Bislang wurde nicht untersucht, ob diese Effekte spezifisch für Fruktose oder andere Zuckerarten sind. Zudem besteht ein steigendes Interesse an Zeittrendanalysen, v.a. zum Konsum von zuckergesüßten Getränke (ZG) und der Zufuhr an anderen Zuckern, die für die Entstehung chronischer Erkrankungen relevant sein könnten. Jedoch fehlen hierzu Daten zu globalen Verzehrsmustern. Daher war das 1. Ziel dieser Arbeit die Analyse weltweiter Zeittrends im Konsum von ZG und anderen Zuckern bei Kindern und Jugendlichen. Das 2. Ziel war die systematische Beleuchtung von Evidenz aus Interventionsstudien hinsichtlich möglicher Effekten von Fruktose bzw. Glukose auf Biomarker der subklinischen Entzündungsneigung. Das 3. Ziel war die Analyse der prospektiven Relevanz der Zuckerzufurh in der Adolszenz (basierend auf Ernährungsdaten und Biomarkern aus 24-h Urinen) für die Insulinsensitivität und subklinische Entzündungsneigung im Erwachsenenalter.
Conical Flow induced by Quenched QCD Jets

description: Quenching is a recently discovered phenomenon in which QCD jets created in heavy ion collisions deposit a large fraction or even all their energy and momentum into the produced matter. At RHIC and higher energies, where that matter is a strongly coupled Quark-Gluon Plasma (sQGP) with very small viscosity, we suggest that this energy/momentum propagate as a collective excitation or ``conical flow''. Similar hydrodynamical phenomena are well known, e.g. the so called sonic booms from supersonic planes. We solve the linearized relativistic hydrodynamic equations to detail the flow picture. We argue that for RHIC collisions the direction of this flow should make a cone at a specific large angle with the jet, of about $70^o$, and thus lead to peaks in particle correlations at the angle $Δϕ=π\pm 1.2$ rad relative to the large-$p_t$ trigger. This angle happens to matchperfectly the position of the maximum in the angular distribution of secondaries associated with the trigger recently seen by the STAR and PHENIX collaborations. We also discuss briefly possible alternative explanations and suggest some further tests to clarify the mechanism.

description: Within the context of very simple avoided crossing, we investigate the investigate the effect of a complex diabatic coupling in determining spin-dependent rate constants and scattering states. We find that, if the molecular geometry is not linear and the Berry force is not zero, one can find significant spin polarization of the products. This study emphasizes that, when analyzing nonadiabatic reactions with spin orbit coupling (and a complex Hamiltonian), one must consider how Berry force affects nuclear motion -- at least in the context of gas phase reactions. Work is currently ongoing as far as extrapolating these conclusions to the condensed phase where interesting spin selection has been observed in recent years.

description: No contexto do comércio internacional as Indicações Geográficas – IG’s têm surgido como um instrumento político-jurídicos para promover e resguardar a originalidade e a procedência de um produto. Contudo, muitas destas normativas têm sido alvo de críticas, à medida que se formalizam como barreiras não-tarifárias e promovem assimetrias no comercio internacional entre os países. Por outro lado, para se estabelecer as IG’s são necessárias mudanças nos padrões produtivos que acabam dinamizando o desenvolvimento socioeconômico de um local/região. Dentro deste contexto o objetivo deste artigo é promover a discussão do papel das Indicações Geográficas, seus condicionamentos que se configuram com barreiras não-tarifarias e a sua potencialidade para dinamizar o desenvolvimento local/regional no Brasil. Como resultado observou-se que discussão das IG’s estão restritas somente à esfera Legal e consideram a realidade dos sistemas produtivos como homogênea entre os países, potencializando o surgimento de barreiras não-tarifárias. Por outro lado, pode-se observar através das modificações socioeconômicas causadas pela Indicação de Procedência Vale dos Vinhedos que as IG’s podem ser uma alternativa para dinamizar o desenvolvimento local/regional no Brasil.---------------------------------------------In the context of international commerce, Geographical Indications – GIs have appeared as a juridical and political instrument to promote and guard the originality and source of a product. However, many of these regulations have been the target of criticism, when they are formalized as non-tariff barriers, thus promoting asymmetries in the international commerce among countries. On the other hand, for the establishment of GIs, some changes are necessary in the production patterns, seeking to activate the social-economical development of a place/region. Considering this context, the objective of this article is to promote the discussion of the role of Geographical Indications, the conditioners that configure it with non-tariff barriers and its potentiality to assist in the local/regional development of Brazil. As a result, it was observed that the discussion of the GIs is restricted only to the Legal sphere and consider the reality of production systems as homogeneous among countries, thus enabling the appearance of non-tariff barriers. On the other hand, it could be observed through the social-economical changes caused by the Vale dos Vinhedos Indication of Origin, that GIs could be considered an alternative for the promotion of the local/regional development of Brazil.

description: Liquid Xenon (LXe) is expected to be an excellent target and detector medium to search for dark matter in the form of Weakly Interacting Massive Particles (WIMPs). Knowledge of LXe ionization and scintillation response to low energy nuclear recoils expected from the scattering of WIMPs by Xe nuclei is important for determining the sensitivity of LXe direct detection experiments. Here we report on new measurements of the scintillation yield of Xe recoils with kinetic energy as low as 10 keV. The dependence of the scintillation yield on applied electric field was also measured in the range of 0 to 4 kV/cm. Results are in good agreement with recent theoretical predictions that take into account the effect of biexcitonic collisions in addition to the nuclear quenching effect.

description: Este artigo trata da aplicabilidade de modelos da família ARCH como ferramenta de análise quanto ao comportamento do retorno do cacau, do boi gordo, do café, tradicionais commodities agrícolas brasileira, servindo de auxílio para decisão dos agentes na compra e venda destes produtos. De forma geral, para as três commodities estudadas, as volatilidades do retorno indicam fortes sinais de persistência, os choques levam um longo tempo para dissipar-se, e choques positivos e negativos têm impacto distinto sobre a volatilidade. Os mercados são assimétricos para o retorno destas commodities. Os mercados futuros do boi gordo e do cacau também sofrem influência do efeito alavancagem, ou seja, se torna mais volátil perante informações negativas do que informações positivas.---------------------------------------------This paper is about the applied of models of the family ARCH as analysis tool with relationship to the behavior of the return of the cocoa, of the fatcow, of the coffee, Brazilian traditional agricultural commodity, serving as aid for the agents decision in the purchase and sale of these products. In a general way, for the three studied commodities the volatilities of the return indicate strong signs of persistent, and the shocks take a long time to vanish, and collide positive and negatives have different impact about the volatility. The markets are asymmetric for the return of these commodities. For the future market of the fat ox and of the cocoa it suffers influence of the effect gearshift, that is to say, becomes more volatile before negative information than positive information.

description: Totally asymmetric simple exclusion processes, consisting of two coupled parallel lattice chains with particles interacting with hard-core exclusion and moving along the channels and between them, are considered. In the limit of strong coupling between the channels, the particle currents, density profiles and a phase diagram are calculated exactly by mapping the system into an effective one-channel totally asymmetric exclusion model. For intermediate couplings, a simple approximate theory, that describes the particle dynamics in vertical clusters of two corresponding parallel sites exactly and neglects the correlations between different vertical clusters, is developed. It is found that, similarly to the case of one-channel totally asymmetric simple exclusion processes, there are three stationary state phases, although the phase boundaries and stationary properties strongly depend on inter-channel coupling. An extensive computer Monte Carlo simulations fully support the theoretical predictions.
