description: Additional file 4. Alignment of target gene sequences and the corresponding amino acid sequences used by pathotyping. Sequence alignment of copper ATPase 1-gene (A and B) and partial gene sequence alignment of type I RM system S protein-gene (C and D) of invasive disease-associated isolates of Swiss S. suis in comparison to the highly virulent reference strain P1/7 are shown visualizing different gene variants and its corresponding protein sequences. Conserved, matching nucleotide residues are illustrated as blue dots, whereas red represents differences of nucleotide sequences. (A) Copper ATPase 1-gene sequences of S. suis PP463 (cps2, ST28), SS470 (cps1/2, ST28), PP423 (cps1/2, ST1133), and PP536 (cps9, ST1105) are represented. Primer sequences of the pathotyping tool are indicated in green. A duplication of a 54 bp long DNA segment in isolate SS470 and deletion of a 21 bp fragment in all represented Swiss isolates could be observed, illustrating a high genetic variability. (B) Corresponding amino acid sequence alignment of Copper ATPase 1 is shown. (C) RM system S protein gene sequences of S. suis PP463 (cps2, ST28), PP423 (cps1/2, ST1133), and PP269 (cps1, ST13) are represented. The forward primer is indicated in green, whereas the reverse primer could not be shown since illustrated Swiss isolates are truncated. (D) Corresponding amino acid sequence alignment of RM systems S protein is shown.
Magnetic Fields in Gamma-Ray Bursts: A Short Review

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Magnetic fields play a crucial role in the physics of Gamma-Ray Bursts (GRBs). Strong observational evidence indicates that the observed afterglow and most likely the prompt emission arise from synchrotron emission. It is possible that Poynting flux plays an important or even dominant role in the relativistic outflow from the inner engine, but like in other astronomical relativistic jets this suggestion is controversial. Finally, it is likely that magnetic fields larger than $10^{15}$ G occur within GRBs' inner engines and contribute to the acceleration and collimation of the relativistic jets. I review here the GRB fireball model and discuss the role that magnetic fields play in its various components. I suggest that the early afterglow, that reflects the initial interaction of the relativistic jet with its surrounding matter is the best available tool to explore the nature of relativistic outflow in astronomical relativistic jets.

description: We present high resolution numerical simulations of compressible magnetohydrodynamic (MHD) turbulence. We concentrate on studies of spectra and anisotropy of velocity and density. We describe a technique of separating different magnetohydrodynamic (MHD) modes (slow, fast and Alfven) and apply it to our simulations. For the mildly supersonic case, velocity and density show anisotropy. However, for the highly supersonic case, we observe steepening of the slow mode velocity spectrum and isotropization of density. Our present studies show that the spectrum of density gets substantially {\it flatter} than the Kolmogorov one.

Thermal fluctuations in pinned elastic systems: field theory of rare events and droplets

description: Using the functional renormalization group (FRG) we study the thermal fluctuations of elastic objects, described by a displacement field u and internal dimension d, pinned by a random potential at low temperature T, as prototypes for glasses. A challenge is how the field theory can describe both typical (minimum energy T=0) configurations, as well as thermal averages which, at any non-zero T as in the phenomenological droplet picture, are dominated by rare degeneracies between low lying minima. We show that this occurs through an essentially non-perturbative *thermal boundary layer* (TBL) in the (running) effective action Gamma[u] at T>0 for which we find a consistent scaling ansatz to all orders. The TBL resolves the singularities of the T=0 theory and contains rare droplet physics. The formal structure of this TBL is explored around d=4 using a one loop Wilson RG. A more systematic Exact RG (ERG) method is employed and tested on d=0 models. There we obtain precise relations between TBL quantities and droplet probabilities which are checked against exact results. We illustrate how the TBL scaling remains consistent to all orders in higher d using the ERG and how droplet picture results can be retrieved. Finally, we solve for d=0,N=1 the formidable "matching problem" of how this T>0 TBL recovers a critical T=0 field theory. We thereby obtain the beta-function at T=0, *all ambiguities removed*, displayed here up to four loops. A discussion of d>4 case and an exact solution at large d are also provided.
Chiral Effective-Field Theory in the Delta(1232) Region: Pion Electroproduction on the Nucleon

description: We develop an extension of chiral perturbation theory to the $Δ$(1232)-resonance energy region and apply it to investigate the pion electroproduction off the nucleon ($e^- N \to e^- Nπ$). We present a complete calculation of this process, in the $Δ$-resonance region, up to next-to-leading order in the {\it $δ$-expansion}. At this order, the only free parameters are the three low-energy constants corresponding to the magnetic (M1), electric (E2), and Coulomb (C2) $γN \to Δ$ transition strength. After fitting these parameters to a few well-known data, our calculation provides a prediction for observables and multipole amplitudes of pion electroproduction. These results compare favorably with the phenomenological multipole solutions and recent experimental results from MIT-Bates and MAMI. Our prediction for the pion-mass dependence of the $γNΔ$ form factors offers an explanation for the discrepancy between the recent lattice-QCD results and the experimental value for the "C2/M1 ratio" at low $Q^2$.

«Être comme tout le monde». Per un’archeologia classicista del mimetismo sociale

description: During the so-called Ancien Régime, the «Process of Civilization» consisted in an education of the body and the language resulting in what we still call politeness. Being polite was to be politum, that is to say clean of any element not corresponding to an average condition. Such process tended to make equal all polite men, those who shared the same ideal of honnêtété. But, if all honnête-hommes had to be equal, or better identical, then identity resulted in the condition of being like all the others. In order to face this paradox, XVIIth and XVIIIth Century European culture developed a keen reflexion on the mask and the arrangement to society and the social eye. The first western theories of the mimetical identity think of identity as the result of a social transaction.

description: This report presents marketing profiles and loan deficiency payment/marketing loan gain profiles for the advisory services followed by the AgMAS Project for the 2002, 2003 and 2004 corn crops. Marketing profiles are constructed by plotting the cumulative net amount priced under each program’s set of recommendations throughout the crop year. Loan deficiency payment/marketing loan gain (LDP/MLG) profiles are constructed by plotting the cumulative percentage of the crop on which the LDP/MLG was claimed during the crop year. Marketing profiles provide information to evaluate the style of advisory services in several ways. The percentage of crop priced is a measure of within-crop year price risk. The higher the proportion of a crop priced, the lower the sensitivity of the farmer’s position value to crop price changes. For example, when 100% of the crop is priced there is no price sensitivity, which means that changes in price do not affect the value of the farmer’s position. On the other hand, when the amount priced is 0%, the value of the farmer’s position will vary in the same proportion as the change in price. Marketing profiles, therefore, allow investigating the evolution of price sensitivity under each service’s set of recommendations along the marketing window. Marketing profiles also provide other useful information. The number of steps in the profile lines and the location of these steps in the marketing window provide information about timing, frequency and size of recommended transactions. It is also possible to determine from the marketing profile figures how intensely a program uses options markets, since when options positions are open the profile line is irregular. In the same way, LDP/MLG profiles provide information about the size and timing of LDP/MLG claims.

description: We present three-loop (NNNLO) corrections to the heavy-to-heavy quark transitions in the limit of equal initial and final quark masses. In analogy with the previously found NNLO corrections, the bulk of the result is due to the beta_0^2 alpha_s^3 corrections. The remaining genuine three-loop effects for the semileptonic b --> c decays are estimated to increase the decay amplitude by 0.2(2)%. The perturbative series for the heavy-heavy axial current converges very well.

Protée et Caméléon. Mimétismes, calembours harmoniques et dissociation des formes dans la musique de la Renaissance
Creators: name: Boccadoro, Brenno
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2016

description: In the realm of language a special case of mimetic illusion is the calembour, where the sound of a phrase signifies something else than what is written. At the end of the XVI century the artistic expression of this phenomenon gave birth to the paintings of Arcimboldo, who separated the contour of an object form the linear organization of the surface, in order to feature another object, through a kind of “polyphonic” dissociation between meaning and form. Strangely enough, nothing has been written, in modern musicology, about the musical analogue of this phenomenon, but one can prove that it was not confined to paintings. The art of dissociating signs and meanings, was very well known by musicians not only through poetics, but also through musical mathematics, and above all by the study of the ancient Greek theory of metabolai, about the qualitative change of an harmonic form through the ambiguity created with others forms.

description: This paper presents the basic principle and theoretical relationships of an original method allowing to retrieve the Wavefront Errors (WFE) of a ground or space-borne telescope when combining its main pupil with a second, decentered reference optical arm. The measurement accuracy of such a "telescope-interferometer" is then estimated by means of various numerical simulations, demonstrating a high performance excepted on limited areas near the telescope pupil rim. In particular, it allows direct phase evaluation (thus avoiding the use of first or second-order derivatives), which is of special interest for the co-phasing of segmented mirrors in future giant telescopes projects. We finally define the useful practical domain of the method, which seems to be better suited for periodical diagnostics of space or ground based telescopes, or to real-time scientific observations in some very specific cases (e.g. the central star in extrasolar planets searching instruments).

description: The purpose of this research report is to summarize the pricing performance of professional market advisory services for the 1995-2003 corn and soybean crops. First, advisory programs in corn do not consistently beat market benchmarks, but tend to consistently beat the farmer benchmark. Second, advisory programs in soybeans exhibit just the opposite pattern, consistently beating the market benchmarks but not the farmer benchmark. Third, in terms of 50/50 revenue, advisory programs show marginal consistency in beating both the market benchmarks and the farmer benchmark. So, the results provide mixed performance evidence with respect to both the market benchmarks and the farmer benchmark.

Real-Time Steering of Curved Sound Beams in a Feedback-based Topological Acoustic Metamaterial

description: We present the concept of a feedback-based topological acoustic metamaterial as a tool for realizing autonomous and active guiding of sound beams along arbitrary curved paths in free two-dimensional space. The metamaterial building blocks are acoustic transducers, embedded in a slab waveguide. The transducers generate a desired dispersion profile in closed-loop by processing real-time pressure field measurements through preprogrammed controllers. In particular, the metamaterial can be programmed to exhibit analogies of quantum topological wave phenomena, which enables unconventional and exceptionally robust sound beam guiding. As an example, we realize the quantum valley Hall effect by creating, using a collocated pressure feedback, an alternating acoustic impedance pattern across the waveguide. The pattern is traversed by artificial trajectories of different shapes, which are reconfigurable in real-time. Due to topological protection, the sound waves between the plates remain localized on the trajectories, and do not back-scatter by the sharp corners or imperfections in the design. The feedback-based design can be used to realize arbitrary physical interactions in the metamaterial, including non-local, nonlinear, time-dependent, or non-reciprocal couplings, paving the way to new unconventional acoustic wave guiding on the same reprogrammable platform. We then present a non-collocated control algorithm, which mimics another quantum effect, rendering the sound beams uni-directional.

description: The purpose of this report is to review the evidence on the profitability of technical analysis. To achieve this purpose, the report comprehensively reviews survey, theoretical and empirical studies regarding technical trading strategies. We begin by overviewing survey studies that have directly investigated market participants’ experience and views on technical analysis. The survey literature indicates that technical analysis has been widely used by market participants in futures markets and foreign exchange markets, and that about 30% to 40% of practitioners appear to believe that technical analysis is an important factor in determining price movement at shorter time horizons up to 6 months. Then we provide an overview of theoretical models that include implications about the profitability of technical analysis. Conventional efficient market theories, such as the martingale model and random walk models, rule out the possibility of technical trading profits in speculative markets, while relatively recent models such as noisy rational expectation models or behavioral models suggest that technical trading strategies may be profitable due to noise in the market or investors’ irrational behavior. Finally, empirical studies are surveyed. In this report, the empirical literature is categorized into two groups, “early” and “modern” studies, according to the characteristics of testing procedures. Early studies indicated that technical trading strategies were profitable in foreign exchange markets and futures markets, but not in stock markets before the 1980s. Modern studies indicated that technical trading strategies consistently generated economic profits in a variety of speculative markets at least until the early 1990s. Among a total of 92 modern studies, 58 studies found positive results regarding technical trading strategies, while 24 studies obtained negative results. Ten studies indicated mixed results. Despite the positive evidence on the profitability of technical trading strategies, it appears that most empirical studies are subject to various problems in their testing procedures, e.g., data snooping, ex post selection of trading rules or search technologies, and difficulties in estimation of risk and transaction costs. Future research must address these deficiencies in testing in order to provide conclusive evidence on the profitability of technical trading strategies.

description: This paper discusses the three invited papers presented in the session titled “New Regulations Require New Solutions: Federal Provisions Governing Concentrated Animal Feeding Operations” (i.e., CAFOs). These papers provide an excellent review of current state and federal laws and an excellent summary of what has been and is currently being done with respect to CAFO regulation. The papers present three different policy approaches: i) alternative performance standards, ii) location-specific regulation, and iii) insurance-based underwriting of CAFO discharges. Each approach has its drawbacks; however, blending theses suggested policies into current regulations would result in efficiency gains.

description: Leafing a book quickly creates metamorphoses of its images and illustrations. Cinema as a medium is based on such visual discontinuity. Both Paolo Gioli, the Italian filmmaker, and Stan Brakhage in America, made very interesting flicker films with and about insects and butterflies : Farfallìo (1993) and Mothlight (1963). Is the buttefly miming the filmic device? To what extent has a film to disguise its mechanism? What is the relation between animation and the animal? I intend to scrutinize the link between flicker film and animality in regard of camouflage and mimicry.

description: The plasma of the lower solar atmosphere consists of mostly neutral particles, whereas the upper solar atmosphere is mostly ionised particles and electrons. A shock that propagates upwards in the solar atmosphere therefore undergoes a transition where the dominant fluid is either neutral or ionised. An upwards propagating shock also passes a point where the sound and Alfvén speed are equal. At this point the energy of the acoustic shock can separated into fast and slow components. How the energy is distributed between the two modes depends on the angle of magnetic field. The separation of neutral and ionised species in a gravitationally stratified atmosphere is investigated. The role of two-fluid effects on the structure of the shocks post-mode-conversion and the frictional heating is quantified for different levels of collisional coupling. Two-fluid numerical simulations are performed using the (P\underline{I}P) code of a wave steepening into a shock in an isothermal, partially-ionised atmosphere. The collisional coefficient is varied to investigate the regimes where the plasma and neutral species are weakly, strongly and finitely coupled. The propagation speeds of the compressional waves hosted by neutral and ionised species vary, therefore velocity drift between the two species is produced as the plasma attempts to propagate faster than the neutrals. This is most extreme for a fast-mode shock. We find that the collisional coefficient drastically changes the features present in the system, specifically the mode conversion height, type of shocks present, and the finite shock widths created by the two-fluid effects. In the finitely-coupled regime fast-mode shock widths can exceed the pressure scale height leading to a new potential observable of two-fluid effects in the lower solar atmosphere.

description: The word «fake» and its several synonyms (copy, forgery, simulacrum) touch on a number of ontological and mimetic issues that since Plato have led directly to contemporary debates. In the present survey we will try to outline a «grammar of fake» through three points: a) the issue of pseudos in Plato and its impact on contemporaneity; b) the notion of hyperreality as absolute fake; c) the dimension of operative fake, grasped in its postmodern enucleation.

description: Through this present piece of work we aim at analysing the integrated system of chicken production in Minas Gerais, in accordance to the Economy in Transaction Costs, seeking especifically to describing the transaction features, administration forms as well as contractual relations. Transactions in the poultry breeding business include a high degree of specificity of actives which undepend on the breeders’ category, whether small or big, besides plenty of uncertainty, quite often , mainly when working in the integrated system via contracts. Such contracts, although they may vary in shape, take certain technical indexes into considerarion, when it comes to rewarding the integrated breeders. The chief advantages in taking part in the integration system are low investiment of one’s own financial resources and low risk. The main disadvantages are the centralization of the power of decision-making , which goes to the industry, as well as the breeders’ low rewarding.
Scale-free properties of weighted networks with connectivity-driven topology

description: The rate equations are used to study the scale-free behavior of the weight distribution in evolving networks whose topology is determined only by degrees of preexisting vertices. An analysis of these equations shows that the degree distribution and thereby the weight distribution remain unchanged when the probability rate of attaching new nodes is replaced with some unnormalized rate determined by the ratio of the degree of a randomly selected old node to the maximal node degree at the current stage of the network evolution. Such a modification of the attachment rule is argued to accelerate considerably numerical simulations of both unweighted and weighted networks belonging to the class of investigated evolving systemes. It is also proved that the studied rate equations have a solution corresponding to the total (concentrated at individual vertices) distribution displaying the power-law behavior for asymptotically large weights.

Comparative sequence analysis : prediction of consensus Xist RNA secondary structure
Creators: name: Chan, Viann Wendy
Publisher: name: University of British Columbia
Year: 2009

description: The typical female mammal has two X chromosomes. However, only one copy remains active, while the other copy is silenced. The Xist gene has been found to remain active on the silenced X chromosome. Other lab experiments have determined that the Xist RNA plays a significant role in the process of X - chromosome inactivation. Our goal in this thesis is to predict a possible consensus structure for the Xist RNA using comparative sequence analysis. Since the Xist RNA structure is not known, we evaluate our approaches on sequences with known structures. There are three main phases for this approach: (i) aligning multiple sequences, (ii) finding stems, and (iii) building the structure. Phases (ii) and (iii) are the main focus of this research. We used the concept of mutual information content to detect potential stems containing mutations. We found potential conserved stems by searching for sequences of complementary paired bases. The stems were then used to find the consensus structure. We investigated two general approaches for building the consensus structure, greedy and randomized methods. We tested these methods on data comprising the following types of RNA: tRNA, 16S rRNA, 23S rRNA, and Xist RNA. We found that our methods accurately predicted the consensus structure for tRNA. However, when we analyzed data sets with longer sequences, the accuracy of our predictions decreased. Of the methods we tested, we found that one of our greedy approaches performed better than the others on all the data sets. We predicted several possible structures for Xist from different alignments. While the overall accuracy of our predicted structures is likely to be low, some of the substructures predicted may give us clues about the true consensus structure.

description: Precise measurements of YbFeO_3 magnetization in the spin-reoirentation temperature interval are performed. It is shown that ytterbium orthoferrite is well described by a recently developed modified mean field theory developed for ErFeO_3. This validates the conjecture about the essential influence of the rare earth ion's anisotropic paramagnetism on the magnetization behavior in the reorientation regions of all orthoferrites with Gamma{4} -> Gamma{24} -> Gamma{2} phase transitions.

Quotient cube and QC-tree : efficient summarizations for semantic OLAP
Creators: name: Zhao, Yan
Publisher: name: University of British Columbia
Year: 2009

description: Most data cube compression approaches focused on reducing the cube size but overlooked preserving the semantics of data cubes. A technique called quotient cube was proposed recently as a summary structure for a data cube that retains its semantics. It can be constructed very efficiently and it leads to a significant reduction in the cube size. However, many issues have not been addressed regarding the application of quotient cubes. For instance, efficient storage and index structures were not provided; No specific algorithm for query answering was given; Incremental maintenance against updates was not discussed. In this thesis work, we are aiming at developing proper solutions to the above problems. Firstly, we introduce the idea of sorted list to index quotient cubes and provide associated query answering algorithms. Secondly, since a tabular representation with additional index is neither compact nor efficient to maintain, we propose a more efficient data structure called QC-tree to store and index quotient cubes. We present a depth-first search based algorithm for constructing QC-trees directly from base tables. Thirdly, we devise efficient algorithms for answering various queries and incrementally maintaining QCtrees against base table updates. An extensive experimental study illustrates the space and time savings achieved by our algorithms. Finally, we implement a quotient cube based data warehouse system to demonstrate our research accomplishments.

description: We present a determination of the effective temperatures, iron abundances, and microturbulent velocities for the pseudophotosphere of V838 Mon on 2002 February 25, and March 2 and 26. Physical parameters of the line forming region were obtained in the framework of a self-consistent approach, using fits of synthetic spectra to observed spectra in the wavelength range 5500-6700A. We obtained Tef = 5330, 5540 and 4960 K, for February 25, March 2, and March 26, respectively. The iron abundance log N(Fe)=-4.7 does not appear to change in the atmosphere of V838 Mon from February 25 to March 26, 2002.
