description: A modelling framework incorporating relationships between agricultural production and groundwater hydrology was developed to estimate the benefits of improved irrigation efficiency in the Riverland of South Australia. Increased irrigation efficiency can generate external benefits to downstream users through reduced discharge of saline groundwater. In the Riverland these benefits are large in comparison to the direct value of the irrigation water. However, the non‐exclusive and site‐specific nature of these benefits makes it difficult to fully internalise them through market instruments such as salinity credits. Achieving optimal irrigation efficiency is likely to require institutional arrangements that promote collective investment and public expenditure.

Large-scale patterns of insect and disease activity in the conterminous United States, Alaska and Hawaii from the national insect and disease survey, 2017. Chapter 2 in K.M. Potter and B.L. Conkling, eds., Forest Health Monitoring: National Status, Trends and Analysis, 2018. General Technical Report SRS-239. Asheville, North Carolina: U.S. Department of Agriculture, Forest Service, Southern Research Station. p. 21-49.

Monitoring the occurrence of forest pest and pathogen outbreaks is important at regional scales because of the significant impact insects and disease can have on forest health across landscapes. National Insect and Disease Survey data collected in 2017 by the Forest Health Protection program of the Forest Service and partners in State agencies identified 63 different mortality-causing agents and complexes on 3.27 million ha in the conterminous United States, and 50 defoliating agents and complexes on approximately 2.34 million ha. Geographic hot spots of forest mortality were associated with bark beetle infestations (mostly fir engraver, western pine beetle, mountain pine beetle, and spruce beetle) in the West, and with emerald ash borer and southern pine beetle in the East. Hot spots of defoliation were associated with gypsy moth, forest tent caterpillar, spruce budworm, baldcypress leafroller, jumping oak gall wasp, white pine needle damage, and browntail moth in the East, and with western spruce budworm in the West. Extensive spruce beetle mortality was detected in Alaska. The most important defoliation agents in Alaska were aspen leafminer, willow leaf blotchminer, and speckled green fruitworm. In Hawaii, approximately 37 000 ha of mortality were attributed to rapid ʻōhiʻa death.

description: Recently, V. Chernousov, S. Gille and A. Merkurjev have obtained a decomposition of the motive of an isotropic smooth projective homogeneous variety analogous to the Bruhat decomposition. Using the method of Bialynicki-Birula, I generalize this decomposition to the case of a (possibly anisotropic) smooth projective variety homogeneous under the action of an isotropic reductive group. This answers a question of N. Karpenko.

Time-dependent Circulation Flows: Iron Enrichment in Cooling Flows with Heated Return Flows

description: We describe a new type of dynamical model for hot gas in galaxy groups and clusters in which gas moves simultaneously in both radial directions. Circulation flows are consistent with (1) the failure to observe cooling gas in X-ray spectra, (2) multiphase gas observed near the centers of these flows and (3) the accumulation of iron in the hot gas from Type Ia supernovae in the central galaxy. Dense inflowing gas cools, producing a positive central temperature gradient, as in normal cooling flows. Bubbles of hot, buoyant gas flow outward. Circulation flows eventually cool catastrophically if the outward flowing gas transports mass but no heat; to maintain the circulation both mass and energy must be supplied to the inflowing gas over a large volume, extending to the cooling radius. The rapid radial recirculation of gas produces a flat central core in the gas iron abundance, similar to many observations. We believe the circulation flows described here are the first gasdynamic, long-term evolutionary models that are in good agreement with all essential features observed in the hot gas: little or no gas cools as required by XMM spectra, the gas temperature increases outward near the center, and the gaseous iron abundance is about solar near the center and decreases outward.

description: Multimodal biometrics are always adopted to improve the recognition performance of single modality biometric systems. Besides introducing more discriminating power to the biometric system, integrating multiple modalities also leads to the curse of dimensionality problem. In this paper, we engage the minimal redundancy maximal relevance criterion to reduce the dimensionality of the feature vector. The minimal redundancy maximal relevance criterion is a feature selection criterion that aims to retain the most relevant elements while discarding the other redundant elements. Our experiments show that, with only 15% of the original feature length, minimal redundancy maximal relevance criterion-based features are able to perform similarly well or even better than the baseline results.

description: The continued-fraction method to solve classical Fokker--Planck equations has been adapted to tackle quantum master equations of the Caldeira--Leggett type. This can be done taking advantage of the phase-space (Wigner) representation of the quantum density matrix. The approach differs from those in which some continued-fraction expression is found for a certain quantity, in that the full solution of the master equation is obtained by continued-fraction methods. This allows to study in detail the effects of the environment (fluctuations and dissipation) on several classes of nonlinear quantum systems. We apply the method to the canonical problem of quantum Brownian motion in periodic potentials both for cosine and ratchet potentials (lacking inversion symmetry).

description: Hamiltonian quantization of an integral compact symplectic manifold M depends on a choice of compatible almost complex structure J. For open sets U in the set of compatible almost complex structures and small enough values of Planck's constant, the Hilbert spaces of the quantization form a bundle over U with a natural connection. In this paper we examine the dependence of the Hilbert spaces on the choice of J, by computing the semi-classical limit of the curvature of this connection. We also show that parallel transport provides a link between the action of the group Symp(M) of symplectomorphisms of M and the Schrodinger equation.

Responses of Pseudomonas aeruginosa to sub-inhibitory antibiotics
Creators: name: Brazas, Michelle Denise
Publisher: name: University of British Columbia
Year: 2009

description: Emergence of resistance is never far behind the introduction of new antimicrobials. In response to antimicrobial challenge, bacteria have the capacity to alter their genomes in order to survive. Antibiotic environments play an important but poorly defined role in mediating such changes. The primary focus of this research was to further define the role of sub-inhibitory antimicrobials in the bacterial response to antimicrobial challenge, with particular attention to adaptive resistance responses. A greater understanding of this biological signature will help in evaluating dosing regimes, understanding mechanism of action and in designing new antimicrobials. The effect of sub-inhibitory ciprofloxacin was studied here, beginning with a global analysis using custom DNA microarray technology. Before conducting this analysis, a custom DNA microarray to 5,378 of the 5,570 open reading frames in the Pseudomonas aeruginosa genome was designed, constructed and validated, along with the accompanying set of RNA isolation, cDNA preparation and labelling, and microarray hybridization protocols. Analysis of the P. aeruginosa transcriptome following exposure to sub-inhibitory ciprofloxacin found expression changes in numerous genes. Prominent among these changes was up-regulation of the SOS DNA-repair response and the R2/F2 pyocin region. These changes were confirmed at both the transcription and protein level. Mutants in the R2/F2 pyocin region were found to be resistant to quinolones as well as other DNA damaging agents like mitomycin C, highlighting a role for this region in mediating susceptibility to DNA damage. I also found that sub-inhibitory ciprofloxacin, particularly 0.3μg/ml ciprofloxacin, induced adaptive resistance responses in P. aeruginosa. Similar responses were not observed in a R2/F2 pyocin mutant strain, although the extent of the role of the R2/F2 pyocin region in mediating adaptive resistance to ciprofloxacin awaits further characterization. Overall, this study indicated that sub-inhibitory concentrations of ciprofloxacin antimicrobial do play an important role in the development of resistance in P. aeruginosa, and highlight the clinical importance of better understanding bacterial-antimicrobial interactions.

description: We investigate several problems in entanglement theory from the perspective of convex optimization. This list of problems comprises (A) the decision whether a state is multi-party entangled, (B) the minimization of expectation values of entanglement witnesses with respect to pure product states, (C) the closely related evaluation of the geometric measure of entanglement to quantify pure multi-party entanglement, (D) the test whether states are multi-party entangled on the basis of witnesses based on second moments and on the basis of linear entropic criteria, and (E) the evaluation of instances of maximal output purities of quantum channels. We show that these problems can be formulated as certain optimization problems: as polynomially constrained problems employing polynomials of degree three or less. We then apply very recently established known methods from the theory of semi-definite relaxations to the formulated optimization problems. By this construction we arrive at a hierarchy of efficiently solvable approximations to the solution, approximating the exact solution as closely as desired, in a way that is asymptotically complete. For example, this results in a hierarchy of novel, efficiently decidable sufficient criteria for multi-particle entanglement, such that every entangled state will necessarily be detected in some step of the hierarchy. Finally, we present numerical examples to demonstrate the practical accessibility of this approach.

description: La firme multinationale (FMN), par définition, contrôle un ensemble de filiales localisées dans différents pays. Elle dispose ainsi de la capacité d'internaliser une partie de ses échanges internationaux au sein d'un marché interne à son organisation (échanges intra-firme). De ce fait, ces échanges intra-firme (EIF) deviennent-ils la norme des échanges internationaux dans le contexte de globalisation croissante des firmes et de régionalisation des économies ? Ils se sont en tout cas très fortement développés dans le secteur agro-alimentaire. Un tiers des échanges internationaux de la France en produits agricoles et alimentaires était réalisé à l'intérieur des firmes multinationales en 1999. Ainsi, loin de générer une substitution entre production et échanges, la constitution des FMN conduit à une transformation dans la nature des échanges, dont les déterminants peuvent différer de ceux réalisés directement sur le marché.

description: Melvin models with irrational twist parameter provide an interesting example of conformal field theories with non-compact target space, and localized states which are arbitrarily close to being delocalized. We study the torus partition sum of these models, focusing on the properties of the regularized dimension of the space of localized states. We show that its behavior is related to interesting arithmetic properties of the twist parameter $γ$, such as the Lyapunov exponent. Moreover, for $γ$ in a set of measure one the regularized dimension is in fact not a well-defined number but must be considered as a random variable in a probability distribution.

description: A SWAP operation between different types of qubits of single photons is essential for manipulating hyperentangled photons for a variety of applications. We have implemented an efficient SWAP gate for the momentum and polarization degrees of freedom of single photons. The SWAP gate was utilized in a single-photon two-qubit quantum logic circuit to deterministically transfer momentum entanglement between a pair of down-converted photons to polarization entanglement. The polarization entanglement thus obtained violates Bell's inequality by more than 150 standard deviations.

description: Le marché du vin a connu, dans les 30 dernières années, d'importantes mutations avec un effondrement de la consommation par tête dans les pays producteurs historiques du sud de l'Europe et l'émergence de nouveaux acteurs en Amérique et en Océanie. Il en est résulté un écart structurel entre l'offre et la demande, générateur d'instabilité des prix et des revenus vitivinicoles, principalement dans l'Union européenne et, plus récemment, en Australie. Ce mouvement s'accompagne d'une restructuration de l'offre avec l'émergence d'un oligopole à franges 1, déjà observé dans d'autres secteurs de l'agroalimentaire. Un groupe dominant de puissantes firmes multinationales se met en place, basé sur une stratégie d'envergure, de forte marketisation des produits et de captation de réseaux de distribution. Cette stratégie trouve ses ressources dans une financiarisation croissante de la gouvernance des firmes. Elle interpelle les pouvoirs publics, en particulier européens, pour une réforme du cadre institutionnel sectoriel.

description: Le secteur de la distribution française est l'un des plus réglementés d'Europe. La dernière réforme dite loi Dutreil II, qui succède à la loi Galland de 1996 a pris effet au 1er janvier 2006. L'un de ses principaux articles impose la réintégration d'une partie des marges arrière (la part excédant 20% du prix unitaire facturé) dans le seuil de revente à perte. Cette mesure destinée à évoluer vers une intégration totale des marges arrière empêche donc désormais les producteurs de fixer un prix plancher uniforme à leurs distributeurs. L'objet de cette réforme est de ramener à un niveau plus faible l'inflation des prix des produits vendus en grande surface, notamment les produits de grandes marques. Les recherches présentées permettent de mieux cerner les mécanismes qui facilitent la hausse ou au contraire, la baisse des prix de détail dans la grande distribution. Les rapports de force entre fournisseurs et distributeurs et les réglementations jouent un rôle crucial dans la compréhension de ces mécanismes. Les analyses développées associent apports théoriques et économétriques.

description: La grande distribution, à ses débuts, avait pour objectif de proposer des prix bas aux consommateurs grâce aux forts volumes commandés aux producteurs de grandes marques qui lui permettaient alors de bénéficier de meilleurs tarifs que le commerce traditionnel. Peu à peu, le rôle des distributeurs a évolué, et il y a maintenant 30 ans que les distributeurs n'ont plus un simple rôle de détaillant : ils sont également gestionnaires de leurs propres marques, les marques de distributeurs (MDD). Pour une immense majorité de produits, dans les rayons et les linéaires des distributeurs, on ne trouve plus exclusivement que des marques nationales (MN). Les consommateurs peuvent également acheter la marque du détaillant qui se décline sous plusieurs offres (voir encadré 1). La première partie de ce texte va s'intéresser à l'origine économique des MDD et mettre à jour quels objectifs économiques les détaillants poursuivent avec le développement des marques de distributeurs. Une deuxième partie se tournera vers les consommateurs en essayant de voir quels sont leurs caractéristiques et les déterminants de leur choix lors de l'achat d'une MDD. Enfin, nous nous intéresserons à la réaction des producteurs de grandes marques, notamment à travers le prix des MN, face au développement des MDD.

description: Az intenzív, iparszerű technológiával kapcsolatos technológiai és fogyasztói kockázatok következtében a mezőgazdasági technológiákban is lényeges változások zajlanak, ezek között terjednek az ún. alacsony inputú technológiák. Ebben a folyamatban az integrált növényvédelem és az integrált gyümölcs(alma-)termelés szerepe is felértékelődött. 2014-től a technológiák alkalmazása az EU-tagországokban kötelező lesz. Az új technológiák bevezetésében fontos szerepet játszanak a gyümölcstermelők és azok termelői, értékesítési szervezetei. A kutatás keretében az integrált növényvédelmi és az integrált almatermelési technológiák elterjedési folyamatát vizsgáltuk. A kutatások alapján megállapítottuk, hogy az új technológiai megoldások elterjedésében az állami irányítás és az állami szabályozás (támogatások) kulcsszerepet játszott, a szakmai szervezetek, a kis- és nagykereskedelmi vállalatok, valamint a szaktanácsadási és egyéb szakmai szervezetek szerepe pedig marginális volt. -------------------------------------------------- Agricultural production technologies are undergoing significant changes due to consumer and technological risks associated with the intensive and industrial technologies. These changes include the spreading of the so-called low input technologies. In this process the role of sustainable technologies – such as integrated fruit (apple) production have increased as well. From 2014 onward it will be mandatory to use the new technologies in the EU member states. Out of the groups affecting the introduction of new technologies, fruit producers and their POs and sales organisations play an important role. Our research looked at the spreading of integrated pest management and integrated apple production technologies. Based on our findings we concluded that the spreading of new technologies was fundamentally driven by governmental control (state subsidies) while the role of professional organisations, retail and wholesale companies and other organisations was marginal.

description: Using a noncommutative inspired Einstein-Euler-Heisenberg black hole, we analyse the associated graviton and light rings that together with the event horizon, provide the necessary components to build its shadow. An analysis of the angular radius of the noncommutative inspired Einstein-Euler-Heisenberg black hole shows that for observers located in its vicinity, it becomes smaller when compared with the commutative case; this effect is more noticeable as noncommutativity increases. The existence of marginally stable bound orbits and the critical angle for the escaping of photons of a noncommutative inspired Einstein-Euler-Heisenberg star is also discussed.

description: This thesis is comprised of three independent chapters on topics in spatial, labour and development economics. I focus on South Africa for which there is a rich and under-exploited set of micro-data and where the peculiar history of the country - including restricted migration and separate development along race lines - makes for a particularly interesting setting. The first chapter provides some of the first evidence on the labour market impacts of female internal migration. Merging detailed migration data from censuses and labour market data from labour force surveys, I exploit substantial time-variation in female migrant inflows into over 200 districts. To identify causal effects, I make use of the unique history of South Africa to construct a plausibly exogenous shift-share instrument for female migrant concentration based on earlier male migration flows from reserves during the Apartheid period. I find that this migration increases the employment and hours worked of high-skilled women (due to substitution in household work) and leads to a reduction in the employment of low-skilled female non-migrants (due to increased competition). The second chapter examines how minimum wage legislation influences the labour market impacts of productivity shocks. Merging district-level high resolution weather data with high frequency data from South Africa’s labour force survey, I examine how the introduction of an agricultural minimum wage affects resilience to weather shocks in the short term using a difference-in-differences approach. I find strong evidence that the substantially increased (and inflexible) wage bill after the minimum wage law leads agricultural employers to retrench formally employed workers in the wake of negative shocks (whereas agricultural employment was more resilient in the pre-law period). In the third and final chapter, I estimate the magnitude of agglomeration externalities in South Africa using a unique geo-coded panel micro-dataset where workers are tracked as they move across the country. The few studies on developing countries to date have estimated much higher agglomeration elasticities than those found in developed countries, but these studies have generally been unable to control for sorting on unobservables or to work with the ideal geographic units. Employing individual fixed effects and an instrumental variable constructed from a novel dataset on historical population settlements, my preferred estimate for regional wage elasticity is approximately 0.03 - in line with estimates for developed countries.

description: Greek Tragedies were staged during festivals, in particular during the festival for Dionysus Eleutherus. The topic of tragedies in festival has been widely studied under different perspectives, starting from Aristoteles until recent years. What happens if festivals in tragedies are studied? What can we say about the ways and the meaning of evoking a festival – a specific festival - on the stage or, more frequently, in the orchestra? In this paper, after a brief sketch about the ways in which the topic of rituals and tragedy have been studied in the last decades, some specific examples are discussed: the Panathenaea in Euripides’ Children of Heracles, as well as the Eleusinian Mysteries in Euripides’ Ion and in Sophocles’ Oedipus at Colonus. Keywords: Tragedy, Festivals, Greek Religion, Historical Anthropology of Ancient Greece Andrea Taddei is associate professor of Ancient Greek Language and Literature at the University of Pisa where he also teaches Anthropology of the Ancient World. He works on the relationships among Ancient Greek religion, Greek law and Greek Literature, on some aspects of History of Culture, and also on the ways of teaching classics in secondary schools. He has edited some previously unpublished texts by Louis Gernet (Diritto e civiltà in Grecia antica, Firenze 2000; Louis Gernet e le tecniche del diritto ateniese, Pisa 2001) and a commented translation of Lycurgus’Against Leocrates (Milano 2012).

description: A hat – különböző tehénlétszámú és termelési színvonalú – társas gazdaságban végzett vizsgálatainkból megállapítható, hogy még a nagy – 8 ezer liter feletti – fajlagos tejhozam mellett is csak a kiegészítő (kvóta-) támogatások tették a tejtermelést nyereségessé. A tejtermeléshez adott különféle támogatások nélkül a hazai tejtermelők egyre nagyobb hányada termel veszteségesen. A vizsgált hat gazdaságból kettő a teljes állományát felszámolta 2010-ben. A tejtermelés költségeiben továbbra is a takarmányköltségek adják a legnagyobb (52%-os) részt, ami a magas tejhozamú (8 ezer liter feletti) állományokban még ennél is nagyobb. A magasabb hozamok ugyanakkor mérséklőleg hatottak a munkabér-, az amortizációs és az általános költségek arányára. A tejtermelés költségei hét év alatt (2004–2010) a társas gazdaságokban országosan közel 20, a takarmányköltségek 14, a munkabérköltségek pedig 66%-kal emelkedtek. A tej értékesítési ára ebben az időszakban – a 2007–2008. évek kivételével – stagnált, illetve 2009-ben 2004-hez képest 5, 2008-hoz képest viszont 25%-kal csökkent. 2010-ben a 2009. évihez képest 13, 2011 első negyedévében pedig közel 50%-os tejárnövekedés következett be, amihez a támogatások 70%-os emelkedése társult. --------------------------------------------- Our study of the six dairy farms – with different number of cows and at various standards of production – run by partnerships found that even when milk yields were high (above 8,000 litres), milk production was only made profitable by the additional (quotabased) subsidies. When discounting the various subsidies granted for milk production, an increasing percentage of Hungarian dairy farmers make a loss. Two of the six farms studied liquidated their entire livestock in 2010. Feed costs remain the largest component of dairy production at 52% - and even higher in herds with a high milk yield (above 8.000 litres). At the same time, higher yields reduced the share of wage costs, amortisation and general costs. Over a seven-year period (2004 to 2010) the costs of dairy production increased by nearly 20% nationally at farms run by partnerships, with feed costs going up by 14% and wage costs by 66%. The selling price of milk, however, remained stagnant in the same period (except in 2007-2008); in 2009 it was 5% lower than in 2004 and 25% lower than in 2008. The selling price of milk rose by 13% from 2009 to 2010 and by nearly 50% to the first quarter of 2011, accompanied by a 70% increase in subsidies.

description: Gamma-ray burst (GRB) 150910A was detected by {\it Swift}/BAT, and then rapidly observed by {\it Swift}/XRT, {\it Swift}/UVOT, and ground-based telescopes. We report Lick Observatory spectroscopic and photometric observations of GRB~150910A, and we investigate the physical origins of both the optical and X-ray afterglows, incorporating data obtained with BAT and XRT. The light curves show that the jet emission episode lasts $\sim 360$~s with a sharp pulse from BAT to XRT (Episode I). In Episode II, the optical emission has a smooth onset bump followed by a normal decay ($α_{\rm R,2} \approx -1.36$), as predicted in the standard external shock model, while the X-ray emission exhibits a plateau ($α_{\rm X,1} \approx -0.36$) followed by a steep decay ($α_{\rm X,2} \approx -2.12$). The light curves show obvious chromatic behavior with an excess in the X-ray flux. Our results suggest that GRB 150910A is an unusual GRB driven by a newly-born magnetar with its extremely energetic magnetic dipole (MD) wind in Episode II, which overwhelmingly dominates the observed early X-ray plateau. The radiative efficiency of the jet prompt emission is $η_γ \approx 11\%$. The MD wind emission was detected in both the BAT and XRT bands, making it the brightest among the current sample of MD winds seen by XRT. We infer the initial spin period ($P_0$) and the surface polar cap magnetic field strength ($B_p$) of the magnetar as $1.02 \times 10^{15}~{\rm G} \leq B_{p} \leq 1.80 \times 10^{15}~{\rm G}$ and 1~ms $\leq P_{0}v\leq 1.77$~ms, and the radiative efficiency of the wind is $η_w \geq 32\%$.
