description: The Transiting Exoplanet Survey Satellite (TESS) is currently concluding its 2-year primary science mission searching 85% of the sky for transiting exoplanets. TESS has already discovered well over one thousand TESS objects of interest (TOIs), but these candidate exoplanets must be distinguished from astrophysical false positives using other instruments or techniques. The 3-band Multi-color Simultaneous Camera for Studying Atmospheres of Transiting Planets (MuSCAT), as well as the 4-band MuSCAT2, can be used to validate TESS discoveries. Transits of exoplanets are achromatic when observed in multiple bandpasses, while transit depths for false positives often vary with wavelength. We created software tools to simulate MuSCAT/MuSCAT2 TESS follow-up observations and reveal which planet candidates can be efficiently distinguished from blended eclipsing binary (BEB) false positives using these two instruments, and which must be validated using other techniques. We applied our software code to the Barclay et al. (2018) predicted TESS discoveries, as well as to TOIs downloaded from the ExoFOP-TESS website. We estimate that MuSCAT (MuSCAT2 values in parentheses) will be able to use its multi-color capabilities to distinguish BEB false positives for $\sim$17% ($\sim$18%) of all TESS discoveries, and $\sim$13% ($\sim$15%) of $R_{\rm pl} < 4R_\oplus$ discoveries. Our TOI analysis shows that MuSCAT (MuSCAT2) can distinguish BEB false positives for $\sim$55% ($\sim$52%) of TOIs with transit depths greater than 0.001, for $\sim$64% ($\sim$61%) of TOIs with transit depths greater than 0.002, and for $\sim$70% ($\sim$68%) of TOIs with transit depth greater than 0.003. Our work shows that MuSCAT and MuSCAT2 can validate hundreds of $R_{\rm pl} < 4R_\oplus$ candidate exoplanets, thus supporting the TESS mission in achieving its Level 1 Science Requirement.

description: While non-linear realizations of continuous symmetries feature derivative interactions and have no potential, non-linear realizations of discrete symmetries feature non-derivative interactions and have a highly suppressed potential. These Goldstone bosons of discrete symmetries have a non-zero potential, but the potential generated from quantum corrections is inherently very highly suppressed. We explore various discrete symmetries and to what extent the potential is suppressed for each of them.

Molecular studies of the structure-function relationships of Psuedomonas aeruginosa OprM : an outer membrane protein associated with efflux
Creators: name: Wong, Kendy Kit-Ying
Publisher: name: University of British Columbia
Year: 2009

description: Pseudomonas aeruginosa demonstrates high intrinsic resistance to multiple classes of structurally unrelated antimicrobial agents. This broad-spectrum resistance is primarily due to a combination of low outer membrane permeability coupled to secondary resistance mechanisms such as the resistance-nodulation-division (RND) efflux systems. The outer membrane protein OprM is involved in intrinsic and mutational multiple-antibiotic resistance as part of two RND efflux systems in P. aeruginosa. To study structure-function relationships for OprM, optimal conditions for oprM overexpression were determined; it appeared that excessive production of the protein was lethal to cells. In addition, overexpression of oprM alone in wild-type P. aeruginosa did not increase the resistance of the cells, suggesting OprM could not function independent of the pump and linker proteins of the efflux systems. OprM was demonstrated for the first time to have channel-forming activities like porins, and was shown to be cation selective like the related TolC protein of Escherichia coli. Based on the functional and sequence similarity between OprM and TolC, and their similar content of a-helical and P-sheet structures determined by circular dichroism spectroscopy, a three-dimensional model of OprM was constructed by threading its sequence to the TolC crystal structure. This suggested that, like TolC, OprM has a distinctive architecture comprising outer membrane p-barrel and periplasmic helical-barrel structures. Analyses of OprM insertion and deletion mutants in the context of this model indicated that the helical barrel is critical for both function and integrity of OprM, while a C-terminal domain localized around the equatorial plane of this helical barrel is dispensable. Unlike the classic porins, extracellular loops appear to play a minimal role in substrate specificity. There appears to be a correlation between the change in antimicrobial activity for certain OprM mutants and the channel size determined by planar bilayer analysis, supporting the "iris" mechanism of action first suggested for TolC. This study provids information on the structure-function relationships of OprM in a three-dimensional context, and will allow more focused hypotheses and studies about the functional domains of OprM and its related family of efflux proteins.

description: Deciphering the distribution of metals throughout galaxies is fundamental in our understanding of galaxy evolution. Nearby, low-metallicity, star-forming dwarf galaxies in particular can offer detailed insight into the metal-dependent processes that may have occurred within galaxies in the early Universe. Here we present VLT/MUSE observations of one such system, JKB 18, a blue diffuse dwarf galaxy with a metallicity of only 12+log(O/H)=7.6$\pm$0.2 (~0.08 Zsol). Using high spatial-resolution integral field spectroscopy of the entire system, we calculate chemical abundances for individual HII regions using the direct method and derive oxygen abundance maps using strong-line metallicity diagnostics. With large-scale dispersions in O/H, N/H and N/O of ~0.5-0.6 dex and regions harbouring chemical abundances outside this 1$σ$ distribution, we deem JKB 18 to be chemically inhomogeneous. We explore this finding in the context of other chemically inhomogeneous dwarf galaxies and conclude that neither the accretion of metal-poor gas, short mixing timescales, or self-enrichment from Wolf-Rayet stars are accountable. Using a galaxy-scale, multi-phase, hydrodynamical simulation of a low-mass dwarf galaxy, we find that chemical inhomogeneities of this level may be attributable to the removal of gas via supernovae and the specific timing of the observations with respect to star-formation activity. This study not only draws attention to the fact that dwarf galaxies can be chemically inhomogeneous, but also that the methods used in the assessment of this characteristic can be subject to bias.

description: Through the 1990s, HPC centers at national laboratories, universities, and other large sites designed distributed system architectures and software stacks that enabled extreme-scale computing. By the 2010s, these centers were eclipsed by the scale of web-scale and cloud computing architectures, and today even upcoming exascale HPC systems are magnitudes of scale smaller than those of datacenters employed by large web companies. Meanwhile, the HPC community has allowed system software designs to stagnate, relying on incremental changes to tried-and-true designs to move between generations of systems. We contend that a modern system software stack that focuses on manageability, scalability, security, and modern methods will benefit the entire HPC community. In this paper, we break down the logical parts of a typical HPC system software stack, look at more modern ways to meet their needs, and make recommendations of future work that would help the community move in that direction.

description: HR 6819 was recently proposed to be a triple system consisting of an inner B-type giant + black hole binary with an orbital period of 40d and an outer Be tertiary. This interpretation is mainly based on two inferences: that the emission attributed to the outer Be star is stationary, and that the inner star, which is used as mass calibrator for the black hole, is a B-type giant. We re-investigate the properties of HR 6819 by spectral disentangling and an atmosphere analysis of the disentangled spectra to search for a possibly simpler alternative explanation for HR 6819. Disentangling implies that the Be component is not a static tertiary, but rather a component of the binary in the 40-d orbit. The inferred radial velocity amplitudes imply an extreme mass ratio of M_2/M_1 = 15 +/- 3. We infer spectroscopic masses of 0.4$^{+0.3}_{-0.1}$ Msun and 6$^{+5}_{-3}$ Msun for the primary and secondary, which agree well with the dynamical masses for an inclination of i = 32 deg. This indicates that the primary might be a stripped star rather than a B-type giant. Evolutionary modelling suggests that a possible progenitor system would be a tight (P_i ~ 2d) B+B binary system that experienced conservative mass transfer. While the observed nitrogen enrichment of the primary conforms with the predictions of the evolutionary models, we find no indications for the predicted He enrichment. We suggest that HR 6819 is a binary system consisting of a stripped B-type primary and a rapidly-rotating Be star that formed from a previous mass-transfer event. In the framework of this interpretation, HR 6819 does not contain a black hole. Interferometry can distinguish between these two scenarios by providing an independent measurement of the separation between the visible components.

Spin Filtering in Storage Rings

Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The spin filtering in storage rings is based on the multiple passage of a stored beam through a polarized internal gas target. Apart from the polarization by transmission, a unique geometrical feature of interaction with the target in such a filtering process, pointed out by H.O. Meyer \cite{Meyer}, is a scattering of stored particles within the beam. A rotation of the spin in the scattering process affects the polarization buildup. We derive here a quantum-mechanical evolution equation for the spin-density matrix of the stored beam which incorporates scattering within the beam. We show how the interplay of transmission and scattering with the beam changes from polarized electrons to polarized protons in the atomic target. After discussions of the FILTEX results on the filtering of stored protons \cite{FILTEX}, we comment on the strategy of spin filtering of antiprotons for the PAX experiment at GSI FAIR \cite{PAX-TP}.

description: Agricultural multifunctionality is the recognition of the joint exercise of economic, environmental and social functions by this sector. In order to make this concept operative for the design of public policies, it is necessary to estimate the social demand for such functions. The main objective of this article is to present an empirical application in this line. For this purpose we have taken the agricultural system of mountain olive groves in Andalusia (Southern Spain) at risk of abandonment after the decoupling of the EU subsidies as a case study. The economic valuation technique used is the Choice Experiment. According to the results, there is a different contribution of each attribute to the improvement of the Society level of utility. The main finding of this study is the identification of a social demand for public goods and services provided by the mountains olive groves. This support for agricultural multifunctionality is heterogeneous in its perception by the citizens and the valuation of the various attributes that the concept involves. Taking into account the impact of an overall improvement in the attribute levels and the socioeconomic characteristics of the respondents, the results suggest that women, people with higher education levels, urban citizens and families with more than three members are those who benefit most from the provision of public goods by agriculture. There is a different contribution of each attribute to the improvement of the Society level of utility. Thus, and taking into account its WTP for each attribute, keeping rural population in their villages and fighting soil erosion (with ~22.61 and ~21.55/individual/year, respectively) seem to be the most valued functions of the mountain olive groves by Andalusian citizens. It follows the improvement of the visual quality of the rural landscapes (~12.20/individual/year) and the reduction of food residuals (~7.14/individual/year). Finally, the results of this study support the new orientation of the CAP which makes decoupled payments on compliance with a range of environmental, food safety, animal and plant health and animal welfare standards, as a result of which, the cross-compliance requirement of the EU agricultural support will, presumably, promote a net increase in social welfare. Yet, according to the results of this research, some efforts should be done to allow cross-compliance to reinforce the objectives of keeping rural population in rural areas and the improvement of the landscape.

description: We discuss the nonlinear elastic response in scale invariant solids. Following previous work, we split the analysis into two basic options: according to whether scale invariance (SI) is a manifest or a spontaneously broken symmetry. In the latter case, one can employ effective field theory methods, whereas in the former we use holographic methods. We focus on a simple class of holographic models that exhibit elastic behaviour, and obtain their nonlinear stress-strain curves as well as an estimate of the elasticity bounds - the maximum possible deformation in the elastic (reversible) regime. The bounds differ substantially in the manifest or spontaneously broken SI cases, even when the same stress-strain curve is assumed in both cases. Additionally, the hyper-elastic subset of models (that allow for large deformations) is found to have stress-strain curves akin to natural rubber. The holographic instances in this category, which we dub black rubber, display richer stress-strain curves - with two different power-law regimes at different magnitudes of the strain.

description: In this paper we price a precipitation option based on empirical weather data from Germany using different pricing methods, among them Burn Analysis, Index Value Simulation and Daily Simulation. For that purpose we develop a daily precipitation model. Moreover, a decorrelation analysis is proposed to assess the spatial basis risk that is inherent to rainfall derivatives. The models are applied to precipitation data in Brandenburg, Germany. Based on simplifying assumptions of the production function, we quantify and compare the risk exposure of grain producers with and without rainfall insurance. It turns out that a considerable risk remains with producers who are remotely located from the weather station. Another finding is that significant differences may occur between the pricing methods. We identify the strengths and weaknesses of the pricing methods and give some recommendations for their applications. Our results are relevant for producers as well as for potential sellers of weather derivatives.

description: In spite of rapid overall economic growth in the 1990s, rural poverty in Pakistan did not decline. Panel data covering rural households in four districts in Pakistan suggest that real incomes of many households declined between the early 1990s and 2002, in spite of modest gains in agricultural output at the provincial and national levels. Net crop income increased by 38 percent for the total sample and by 81 percent growth for poor farmers, whose total incomes rose by 23 percent. Nevertheless, rural non-agricultural incomes fell by 30 percent overall and by 16 percent for poor households, indicating that the income and employment multipliers of agricultural growth were insufficient to lead to substantial gains in rural non-farm incomes. A decline in remittances was also a major factor in reducing real incomes in three of the four districts. Controlling for other factors, electrification of the village and paved roads raise household real expenditures by about 75 and 100 percent, respectively, suggesting that accelerated public investments in village electrification could have a significant impact on rural poverty.

description: We study inelastic scattering of energetic electrons off a Kondo impurity. If the energy E of the incoming electron (measured from the Fermi level) exceeds significantly the Kondo temperature T_K, then the differential inelastic cross-section σ(E,w), i.e., the cross-section characterizing scattering of an electron with a given energy transfer w, is well-defined. We show that σ(E,w) factorizes into two parts. The E-dependence of σ(E,w) is logarithmically weak and is due to the Kondo renormalization of the effective coupling. We are able to relate the w-dependence to the spin-spin correlation function of the magnetic impurity. Using this relation, we demonstrate that in the absence of magnetic field the dynamics of the impurity spin causes the electron scattering to be inelastic at any temperature. Quenching of the spin dynamics by an applied magnetic field results in a finite elastic component of the electron scattering cross-section. The differential scattering cross-section may be extracted from the measurements of relaxation of hot electrons injected in conductors containing localized spins.

description: We initiate the study of applications of machine learning to Seiberg duality, focusing on the case of quiver gauge theories, a problem also of interest in mathematics in the context of cluster algebras. Within the general theme of Seiberg duality, we define and explore a variety of interesting questions, broadly divided into the binary determination of whether a pair of theories picked from a series of duality classes are dual to each other, as well as the multi-class determination of the duality class to which a given theory belongs. We study how the performance of machine learning depends on several variables, including number of classes and mutation type (finite or infinite). In addition, we evaluate the relative advantages of Naive Bayes classifiers versus Convolutional Neural Networks. Finally, we also investigate how the results are affected by the inclusion of additional data, such as ranks of gauge/flavor groups and certain variables motivated by the existence of underlying Diophantine equations. In all questions considered, high accuracy and confidence can be achieved.

However, parametric techniques often suggest a higher degree of price transmission than that implied by threshold models.

description: High angular resolution observations at optical wavelengths provide valuable insights in stellar astrophysics, directly measuring fundamental stellar parameters, and probing stellar atmospheres, circumstellar disks, elongation of rapidly rotating stars, and pulsations of Cepheid variable stars. The angular size of most stars are of order one milli-arcsecond or less, and to spatially resolve stellar disks and features at this scale requires an optical interferometer using an array of telescopes with baselines on the order of hundreds of meters. We report on the successful implementation of a stellar intensity interferometry system developed for the four VERITAS imaging atmospheric-Cherenkov telescopes. The system was used to measure the angular diameter of the two sub-mas stars $β$ Canis Majoris and $ε$ Orionis with a precision better than 5%. The system utilizes an off-line approach where starlight intensity fluctuations recorded at each telescope are correlated post-observation. The technique can be readily scaled onto tens to hundreds of telescopes, providing a capability that has proven technically challenging to current generation optical amplitude interferometry observatories. This work demonstrates the feasibility of performing astrophysical measurements with imaging atmospheric-Cherenkov telescope arrays as intensity interferometers and the promise for integrating an intensity interferometry system within future observatories such as the Cherenkov Telescope Array.

description: The effect of exclusive lanes for nonmotorized transportation (NMT) in Shanghai, China, and Surakarta, Indonesia, is investigated. NMT speeds in exclusive lanes and ordinary (mixed traffic) lanes were compared to examine the impact of the exclusive paths, as it is not possible to conduct before and after studies. Contradicting results were obtained between Shanghai and Surakarta. Exclusive bike lanes were found to have a positive impact in Shanghai: mean riding speeds on the exclusive lanes were significantly faster than those on the ordinary paths. But no significant difference was found between the mean speeds of exclusive and ordinary lanes in Surakarta. The NMT exclusive paths have no effect on the speeds of their NMT modes.

description: International climate negotiations have specified that projects under the Clean Development Mechanism (CDM) should not lead to a "diversion" of official development assistance (ODA). It is however unchallenged that ODA can be used in capacity building for the CDM. Diversion can be interpreted in financial, sectoral and regional terms. There are possibilities to use ODA benchmarks to define diversion such as the UN 0.7% target but they are unlikely to be politically acceptable. On the project level, three main options exist but none of them is perfect. The value of emissions credits (CERs) could be deducted from ODA. This however leads to a long-term pressure on the ODA level. Differentiating an ODA-financed baseline project and a "piggyback" CDM option is likely to be arbitrary in many circumstances. Even if CERs do not accrue for the ODA share of the investment, still private CDM projects are crowded out due to the subsidising of CDM projects.

description: This paper analyses the role of the European Union in promoting liberalisation among its member states and in crafting the multilateral regime for telecommunications services. It begins by analysing the origins of the EU regime, describing its contours and assessing its implementation. It then examines the interaction between the EU and the multilateral regime, examining the Uruguay Round and post-Uruguay Round negotiations on telecommunications services and outlining the issues under consideration in the GATS 2000 negotiations. It then proceeds to assess how the regulatory developments at the national, European and multilateral levels coexist and interact. Dieses Papier analysiert die Rolle der Europäischen Union bei der Liberalisierung der Telekommunikationsmärkte ihrer Mitgliedstaaten und bei der Formung des multilateralen Regimes für Telekommunikationsdienstleistungen. Es beginnt mit einer Darstellung der Ursprünge des EU-Regimes, beschreibt seine Merkmale und beurteilt seine Umsetzung. Dann untersucht das Papier die Zusammenhänge zwischen dem EU und dem multilateralen Regime, analysiert die Uruguay-Runde und die Folgeverhandlungen bezüglich der Telekommunikationsdienstleistungen und skizziert einige Themen der neuen GATS 2000-Runde. Schließlich beschäftigt es sich mit der Frage, wie die nationalen, europäischen und multilateralen Entwicklungen bei der Regulierung der Telekommunikationsmärkte verlaufen und wie sie aufeinander einwirken.

description: After fixing the Maximal Abelian gauge in SU(2) lattice gauge theory we decompose the nonabelian gauge field into the so called monopole field and the modified nonabelian field with monopoles removed. We then calculate respective static potentials and find that the potential due to the modified nonabelian field is nonconfining while, as is well known, the monopole field potential is linear. Furthermore, we show that the sum of these potentials approximates the nonabelian static potential with 5% or higher precision at all distances considered. We conclude that at large distances the monopole field potential describes the classical energy of the hadronic string while the modified nonabelian field potential describes the string fluctuations. Similar decomposition was observed to work for the adjoint static potential. A check was also made of the center projection in the direct center gauge. Two static potentials, determined by projected $Z_2$ and by modified nonabelian field without $Z_2$ component were calculated. It was found that their sum is a substantially worse approximation of the SU(2) static potential than that found in the monopole case. It is further demonstrated that similar decomposition can be made for the flux tube action/energy density.

description: A crucial diagnostic that can tell us about processes involved in the formation and dynamical evolutionof planetary systems is the angle between the rotation axis of a star and a planet's orbital angular momentum vector ("spin-orbit" alignment or "obliquity"). Here we present the first spin-orbit alignment measurement for a wide-separation exoplanetary system, namely on the directly-imaged planet $β$ Pictoris b. We use VLTI/GRAVITY spectro-interferometry with an astrometric accuracy of 1 $μ$as (microarcsecond) in the Br$γ$ photospheric absorption line to measure the photocenter displacement associated with the stellar rotation. Taking inclination constraints from astroseismology into account, we constrain the 3-dimensional orientation of the stellar spin axis and find that $β$ Pic b orbits its host star on a prograde orbit. The angular momentum vectors of the stellar photosphere, the planet, and the outer debris disk are well-aligned with mutual inclinations $<3\pm5^{\circ}$, which indicates that $β$ Pic b formed in a system without significant primordial misalignments. Our results demonstrate the potential of infrared interferometry to measure the spin-orbit alignment for wide-separation planetary systems, probing a highly complementary regime to the parameter space accessible with the Rossiter-McLaughlin effect. If the low obliquity is confirmed by measurements on a larger sample of wide-separation planets, it would lend support to theories that explain the obliquity in Hot Jupiter systems with dynamical scattering and the Kozai-Lidov mechanism.

Forecasting Trend Output in the Euro Area

description: This paper estimates and forecasts trend output and output gaps for the Euro area. In the monetary strategy of the European Central Bank (ECB), trend output is used to forecast a reference value for money. For this purpose, trend output must be forecasted as well. In this paper, a permanent-transitory decomposition (PT) based on cointegration restrictions gives an estimate of trend output in the Euro area. Ex-ante forecasts of trend output are generated and to get an impression of the forecast uncertainty, bootstrap simulation is employed to construct prediction intervals that take into consideration estimation uncertainty. The empirical uncertainty around trend output is relatively smaller than the uncertainty of the output gap. The absolute uncertainty of both indicators is quite large and questions their usefulness for monetary policy. When relying on such indicators monetary authorities should clarify this uncertainty.
Aspekte einer Reform des Stabilitats - und Wachstumspakts

description: Der Stabilitats- und Wachstumspakt ist in den vergangenen Jahren von einer zunehmenden Zahl von Landern verletzt worden. Dies deutet auf Mangel in der Gestaltung bzw. in der Umsetzung des Pakts hin. Kritisiert wird insbesondere das zentrale Kriterium für eine nachhaltige Finanzpolitik, eine für alle Länder einheitliche Obergrenze von 3 % für die gesamtstaatliche Defizitquote, nicht zuletzt wegen der damit verbundenen Asymmetrie. Zugleich wurden zahlreiche Alternativen vorgeschlagen: eine Orientierung der Finanzpolitik an den gesamtstaatlichen Schulden, am strukturellen Budgetsaldo, mit oder ohne besondere Berücksichtigung der öffentlichen Investitionen, sowie an einem für die mittlere Frist festgelegten linearen Pfad für die öffentlichen Ausgaben. Die Analyse zeigt, dass speziellen Vorteilen der einzelnen Konzepte jeweils auch Schwächen gegenüberstehen. Unter den Vorschlägen, die eine Umsetzung des Pakts besser gewährleisten sollen, wird die Schaffung eines unabhängigen Gremiums dargestellt. The Stability and Growth Pact, intended to guarantee solid fiscal policy in each member state of the euro area, was breached by an increasing number of countries in recent years, indicating flaws in design and implementation. The criterion of a common ceiling of 3 % for the deficit ratio, central for this rule, is criticised especially, not least because of the asymmetry embodied. Connected with this several alternative criteria for an orientation of fiscal policy were suggested, for the general government each: public debt, a cyclically-adjusted budget balance, with or without special allowance for public investment, and a well defined medium-term linear path for public expenditure. General features of the pros and cons of these basic alternatives are presented. Among the suggestions to provide for a better implementation the creation of an independent council is illustrated.

The host galaxy/AGN connection in nearby early-type galaxies. Is there a miniature radio-galaxy in every "core" galaxy?

description: This is the second of a series of three papers exploring the connection between the multiwavelength properties of AGN in nearby early-type galaxies and the characteristics of their hosts. In Capetti et al. (2005) we presented a study of the surface brightness profiles for the 65 objects with available archival HST images out of the 116 radio-detected galaxies. We classified early-type galaxies into ``core'' and ``power-law'' galaxies, discriminating on the basis of the slope of their nuclear brightness profiles. Here we focus on the 29 core galaxies (hereafter CoreG). We used HST and Chandra data to isolate their nuclear emission. The CoreG invariably host radio-loud nuclei, with an average radio-loudness parameter of Log R = 3.6. The optical and X-ray nuclear luminosities correlate with the radio-core power, smoothly extending the analogous correlations already found for low luminosity radio-galaxies. This supports the interpretation of a common non-thermal origin of the nuclear emission also for CoreG. The luminosities of the nuclear sources, most likely dominated by jet emission, set firm upper limits, as low as L/L_Edd = 10^{-9} in both the optical and X-ray band, on any emission from the accretion process. The similarity of CoreG and LLRG indicates that they are drawn from the same population of early-type galaxies. LLRG represent only the tip of the iceberg associated with (relatively) high activity levels, with CoreG forming the bulk of the population. A minimum black hole mass of M_{BH} = 10^8 M_sun is apparently associated with the radio-loud nuclei in both CoreG and LLRG, but this effect must be tested on a sample of less luminous galaxies, likely to host smaller black holes. ABRIDGED.
