description: Previously, large discrepancies have been found between theory and observation for Fe XV emission line ratios in solar flare spectra covering the 224-327 A wavelength range, obtained by the Naval Research Laboratory's S082A instrument on board Skylab. These discrepancies have been attributed to either errors in the adopted atomic data or the presence of additional atomic processes not included in the modelling, such as fluorescence. However our analysis of these plus other S082A flare observations (the latter containing Fe XV transitions between 321-482 A), performed using the most recent Fe XV atomic physics calculations in conjunction with a CHIANTI synthetic flare spectrum, indicate that blending of the lines is primarily responsible for the discrepancies. As a result, most Fe XV lines cannot be employed as electron density diagnostics for solar flares, at least at the spectral resolution of S082A and similar instruments (i.e. ~ 0.1 A). An exception is the intensity ratio I(321.8 A)/I(327.0 A), which appears to provide good estimates of the electron density at this spectral resolution.

An in vitro biomechanical study of impaction allografting for revision total hip arthroplasty
Creators: name: Robinson, Marcus Calem
Publisher: name: University of British Columbia
Year: 2009

description: The impaction allografting procedure for the treatment of failed hip reconstructions has shown promising results, but a number of intraoperative and postoperative concerns exist. A fundamental understanding of the biomechanical characteristics of the construct would help in providing surgical guidelines to address the issues of stem subsidence, femoral fracture, and resource usage. To this end, an in vitro model was developed to compare the structural response of the construct as a function of the material composition (i.e. 100% morsellized bone, 100% cement, and a combination of morsellized bone and cement as used in the traditional impaction allografting procedure), distal plug fixation (i.e. fixed or free distal plug), and stem surface finish (i.e. polished or polished and coated with mould release). To replicate clinical conditions while eliminating confounding variables, the model system comprised aluminum tubing to represent the femur and an axisymmetric singletaper stem. One orthopaedic surgeon performed all procedures in a total of 25 specimens. Successive uniaxial cyclic compression was applied to the models to simulate 1•BW (i.e. body weight), 2•BW, and 3•BW loading for a total of 1000 cycles. Applied force, axial stem displacement, strain at the outside of the tubes were recorded to calculate construct stiffness, subsidence, and hoop and axial strain. At the conclusion of each test, the stems were pulled out of the tubes to gain further insight into the relationship among material properties, loading, and interfacial shear strengths. The structural behaviour of the impaction allografting (IA) construct was closer to that of the 100%o cement (CE) construct than that of the 100% morsellized bone (MB) construct. The IA and CE constructs did not show substantial stem subsidence and hence exhibited predominantly axial strain resulting from high shear stresses at the stem-cement interface. Conversely, the MB specimens showed excessive stem subsidence and consequent increase in the hoop:axial strain ratio with morsellized bone compression. There was no change in the structural behaviour of the specimens when a mould release-coated stem was substituted for the polished stem. With the distal plug removed, the IA and CE specimens slipped at the tube-material interface, suggesting that the distal plug or some other form of external or geometric support is required for structural integrity.

title: De la forme à l’informe : La posture transgressive de l’art informel à travers Tàpies et Saura
Creators: name: Heredia, Martine
Publisher: name: Savoirs en prisme
Year: 2020

description: Il s’agira ici de comprendre comment Antoni Tàpies (1923-2012) et Antonio Saura (1930-1998) ont renouvelé l’art et de saisir de quelles contraintes il leur a fallu se défaire pour atteindre plus de liberté et d’authenticité dans leur création artistique et établir un nouveau contrat de réception. L’analyse du processus créatif de Tàpies et de Saura s’attachera à montrer que le peintre informel non seulement nie la forme, mais vise aussi à se débarrasser de la contrainte de l’image en la refusant, pour que se réalise un nouvel espace pictural. La réflexion permettra de voir que, tout en étant animés des mêmes intentions, les deux artistes espagnols ont des approches différentes. Ainsi, Antoni Tàpies vide l’espace pour que la matière domine, produisant une peinture sans image, alors qu’Antonio Saura part au contraire des images pour les détruire.

description: We use high-resolution N-body simulations to study the galaxy-cluster cross-sections and the abundance of giant arcs in the $Λ$CDM model. Clusters are selected from the simulations using the friends-of-friends method, and their cross-sections for forming giant arcs are analyzed. The background sources are assumed to follow a uniform ellipticity distribution from 0 to 0.5 and to have an area identical to a circular source with diameter $1\arcsec$. We find that the optical depth scales as the source redshift approximately as $τ_{1''} = 2.25 \times 10^{-6}/[1+(\zs/3.14)^{-3.42}]$ ($0.63$. The optical depth is sensitive to the source redshift, in qualitative agreement with Wambsganss et al. (2004). However, our overall optical depth appears to be only $\sim$ 10% to 70% of those from previous studies. The differences can be mostly explained by different power spectrum normalizations ($σ_8$) used and different ways of determining the $L/W$ ratio. Finite source size and ellipticity have modest effects on the optical depth. We also found that the number of highly magnified (with magnification $|μ|>10$) and ``undistorted'' images (with $L/W<3$) is comparable to the number of giant arcs with $|μ|>10$ and $L/W>10$. We conclude that our predicted rate of giant arcs may be lower than the observed rate, although the precise `discrepancy' is still unclear due to uncertainties both in theory and observations.
description: Revised version after the referee's reports (32 pages,13figures). The paper has been significantly revised with many additions. The new version includes more detailed comparisons with previous studies, including the effects of source size and ellipticity. New discussions about the redshift distribution of lensing clusters and the width of giant arcs have been added

description: We propose a methodology for intercomparing climate models and evaluating their performance against benchmarks based on the use of the Wasserstein distance (WD). This distance provides a rigorous way to measure quantitatively the difference between two probability distributions. The proposed approach is flexible and can be applied in any number of dimensions; it allows one to rank climate models taking into account all the moments of the distributions. By selecting the combination of climatic variables and the regions of interest, it is possible to highlight specific model deficiencies. The WD enables a comprehensive evaluation of climate model skill. We apply this approach to a selected number of physical fields, ranking the models in terms of their performance in simulating them, and pinpointing their weaknesses in the simulation of some of the selected physical fields in specific areas of the Earth.

description: In the context of cybersecurity, tracking the activities of coordinated hosts over time is a daunting task because both participants and their behaviours evolve at a fast pace. We address this scenario by solving a dynamic novelty discovery problem with the aim of both re-identifying patterns seen in the past and highlighting new patterns. We focus on traffic collected by Network Telescopes, a primary and noisy source for cybersecurity analysis. We propose a 3-stage pipeline: (i) we learn compact representations (embeddings) of hosts through their traffic in a self-supervised fashion; (ii) via clustering, we distinguish groups of hosts performing similar activities; (iii) we track the cluster temporal evolution to highlight novel patterns. We apply our methodology to 20 days of telescope traffic during which we observe more than 8 thousand active hosts. Our results show that we efficiently identify 50-70 well-shaped clusters per day, 60-70% of which we associate with already analysed cases, while we pinpoint 10-20 previously unseen clusters per day. These correspond to activity changes and new incidents, of which we document some. In short, our novelty discovery methodology enormously simplifies the manual analysis the security analysts have to conduct to gain insights to interpret novel coordinated activities.

description: Introduction: Skateboarding is one of the most popular cultures in Brazil, with more than 8.5 million skateboarders. Nowadays, the discipline of street skating has gained recognition among other more classical sports and awaits its debut at the Tokyo 2020 Summer Olympic Games. This study aimed to explore the state-of-the-art for inertial measurement unit (IMU) use in skateboarding trick detection, and to develop new classification methods using supervised machine learning and artificial neural networks (ANN). Methods: State-of-the-art knowledge regarding motion detection in skateboarding was used to generate 543 artificial acceleration signals through signal modeling, corresponding to 181 flat ground tricks divided into five classes (NOLLIE, NSHOV, FLIP, SHOV, OLLIE). The classifier consisted of a multilayer feed-forward neural network created with three layers and a supervised learning algorithm (backpropagation). Results: The use of ANNs trained specifically for each measured axis of acceleration resulted in error percentages inferior to 0.05%, with a computational efficiency that makes real-time application possible. Conclusion: Machine learning can be a useful technique for classifying skateboarding flat ground tricks, assuming that the classifiers are properly constructed and trained, and the acceleration signals are preprocessed correctly.

A Quantum Langevin Formulation of Risk-Sensitive Optimal Control

Publisher: name: arXiv
Year: 2004
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this paper we formulate a risk-sensitive optimal control problem for continuously monitored open quantum systems modelled by quantum Langevin equations. The optimal controller is expressed in terms of a modified conditional state, which we call a risk-sensitive state, that represents measurement knowledge tempered by the control purpose. One of the two components of the optimal controller is dynamic, a filter that computes the risk-sensitive state. The second component is an optimal control feedback function that is found by solving the dynamic programming equation. The optimal controller can be implemented using classical electronics. The ideas are illustrated using an example of feedback control of a two-level atom.

description: We consider theoretically a superlattice formed by thin conducting layers separated spatially between insulating layers. The dispersion of two coupled phonon-plasmon modes of the system is analyzed by using Maxwell's equations, with the influence of retardation included. Both transmission for the finite plate as well as absorption for the semi-infinite superlattice in the infrared are calculated. Reflectance minima are determined by the longitudinal and transverse phonon frequencies in the insulating layers and by the density-state singularities of the coupled modes. We evaluate also the Raman cross section from the semi-infinite superlattice.

description: Investment in irrigation infrastructure and technologies, particularly those that reduce on-farm water use have become a major focus of government programs both at a State and Commonwealth level. Particular attention has been given to increasing the uptake of water “saving” technologies among irrigators. The design of programs capable of achieving government objectives at least cost requires an understanding of farm level investment decisions. In this context, the influence of uncertainty on decisions to invest in irrigation technology and infrastructure is examined. The potential for uncertainty to influence investment decisions via strategies to manage risk is demonstrated using the method of real options valuation. The approach is applied to case studies of investment in evaporation mitigation technologies. It is shown that there are circumstances where uncertainty surrounding the value of water savings is significant enough to influence the decision to invest in water saving technologies. The results also demonstrate that where uncertainty exists, rates of subsidy to encourage faster uptake of these technologies need to be higher than those indicated by traditional NPV analysis. This is further exacerbated when irrigators are required to relinquish water entitlements in return for the subsidy.
Non-Thermal Emission from AGN Coronae

description: Accretion disk coronae are believed to account for X-ray emission in Active Galactic Nuclei (AGNs). In this paper the observed emission is assumed to be due to a population of relativistic, non-thermal electrons (e.g. produced in a flare) injected at the top of an accretion disk magnetic loop. While electrons stream along magnetic field lines their energy distribution evolves in time essentially because of inverse Compton and synchrotron losses. The corresponding time dependent emission due, in the X-ray energy range, to the inverse Compton mechanism, has been computed. Since the typical decay time of a flare is shorter than the integration time for data acquisition in the X-ray domain, the resulting spectrum is derived as the temporal mean of the real, time-dependent, emission, as originated by a series of consecutive and identical flares. The model outcome is compared to both the broad band BeppoSAX X-ray data of the bright Seyfert 1 NGC 5548, and to a few general X-ray spectral properties of Seyfert 1s as a class. The good agreement between model and observations suggests that the presently proposed non-thermal, non-stationary model could be a plausible explanation of AGN X-ray emission, as an alternative to thermal coronae models.

description: The electrical energy system has attracted much attention from an increasingly diverse research community. Many theoretical predictions have been made, from scaling laws of fluctuations to propagation velocities of disturbances. However, to validate any theory, empirical data from large-scale power systems are necessary but are rarely shared openly. Here, we analyse an open data base of measurements of electric power grid frequencies across 17 locations in 12 synchronous areas on three continents. The power grid frequency is of particular interest, as it indicates the balance of supply and demand and carries information on deterministic, stochastic, and control influences. We perform a broad analysis of the recorded data, compare different synchronous areas and validate a previously conjectured scaling law. Furthermore, we show how fluctuations change from local independent oscillations to a homogeneous bulk behaviour. Overall, the presented open data base and analyses constitute a step towards more shared, collaborative

description: The Natural Heritage Trust and the National Action Plan for Salinity and Water Quality were major national policies focused on land and water degradation and nature conservation in Australia. These programs fell a long way short of achieving their stated goals. It is proposed that to be able to spend their considerable public funds in cost effective ways, they would have needed a number of particular characteristics. Among other things, they needed to prioritise investments well, consistent with an appropriate role of government, and based on analyses that integrated good quality bio-physical and socio-economic information. They needed to select policy mechanisms that would be appropriate for the circumstances. The incentives created by program rules and procedures should have encouraged environmental managers responsible for program delivery to pursue environmental outcomes cost-effectively. However, the programs did not satisfy these criteria. Prospects for improving matters in the new national program, Caring for our Country, are discussed. It will be difficult to deliver outcomes cost-effectively in the new program for reasons that include capacity constraints in government agencies, time pressures on policy development, and political priorities of governments.

What is Evolutionary Aesthetics for?
Creators: name: Dreon, Roberta
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2013

description: What is evolutionary aesthetics for? This paper investigates whether and in what way it may be useful to develop a conception of artistic practices as culturally differentiated behaviours in response to our vital needs, without resorting to a reductionist and substantial conception of human nature. Through an approach based on cultural naturalism, the suggested inquiry is also meant to verify whether in the debate on the evolutionary origins of the arts there are conceptual tools and theses which can help understand the present state of the arts and aesthetic consumption. Recognizing the historical, geographical and social conditioning that affects the traditional aesthetic stance and the conception of art as an autonomous sphere does not exclude the possibility of investigating the roles the arts play in human interactions with the world, the deep-seated anthropological needs they stem from, and the variety of ways in which they express these needs. In this light it seems more fruitful to conceive of the arts in terms of artyfing behaviours than to search for a more universal definition of art. The paper further suggests that the notion of “making special” – understood by Ellen Dissanayake as a shared anthropological attitude – makes it possible to recover those emotional and social dimensions in which artistic practices have their roots and which they in turn contribute to sustaining, arguing that a more critical evaluation is required of the structural ambivalence of these dimensions and of their consequences on artistic dynamics.

description: We report structure formation in submonolayers of magnetic microparticles subjected to periodic electrostatic and magnetic excitations. Depending on the excitation parameters, we observe the formation of a rich variety of structures: clusters, rings, chains, and networks. The growth dynamics and shapes of the structures are strongly dependent on the amplitude and frequency of the external magnetic field. We find that for pure ac magnetic driving at low densities of particles, the low-frequency magnetic excitation favors clusters while high frequency excitation favors chains and net-like structures. An abrupt phase transition from chains to a network phase was observed for a high density of particles.

description: We present an analysis of K2 light curves (LCs) from Campaigns 4 and 13 for members of the young ($\sim$3 Myr) Taurus association, in addition to an older ($\sim$30 Myr) population of stars that is largely in the foreground of the Taurus molecular clouds. Out of 156 of the highest-confidence Taurus members, we find that 81\% are periodic. Our sample of young foreground stars is biased and incomplete, but nearly all (37/38) are periodic. The overall distribution of rotation rates as a function of color (a proxy for mass) is similar to that found in other clusters: the slowest rotators are among the early M spectral types, with faster rotation towards both earlier FGK and later M types. The relationship between period and color/mass exhibited by older clusters such as the Pleiades is already in place by Taurus age. The foreground population has very few stars, but is consistent with the USco and Pleiades period distributions. As found in other young clusters, stars with disks rotate on average slower, and few with disks are found rotating faster than $\sim$2 d. The overall amplitude of the light curves decreases with age and higher mass stars have generally lower amplitudes than lower mass stars. Stars with disks have on average larger amplitudes than stars without disks, though the physical mechanisms driving the variability and the resulting light curve morphologies are also different between these two classes.

description: Genetically modified (GM) crops have been largely adopted in major exporting countries thereby representing a dominant share of a few key agricultural commodities that are traded in international markets. Regulatory reviews and approvals for the cultivation and marketing of GM crops, however, are country-specific and significant discrepancies in the amount of time required to review and approve new GM crops between importing and exporting countries has led to “asynchronous approvals”. Trade disruptions created by asynchronous approvals of GM crops are expected and can quickly deteriorate into effective trade bans because perfect segregation between approved and unapproved GM crops is difficult. The issues we examine in this paper are the potential market and welfare impacts from trade disruptions that might be caused by asynchronous regulatory approvals of new GM crops. We develop a trade model consisting of two composite importing countries and one exporting country. We first derive a baseline equilibrium where no unapproved events exists. When then derive a second equilibrium so that the market and welfare impacts of asynchronous approval on consumers and producers in each composite country can be analyze and discussed. We found that asynchronous approvals tend to increase prices, reduce consumer surplus and increase profits of producers of identity preserved commodities in all countries. However, we found that the aggregate quantities consumed and the profits of commodity producers are depend on the relative size of the export market in the countries where event are not approved.

description: A novel phenomenological approach to the analysis of the conductivities of incoherent layered crystals is presented. It is based on the fundamental relationship between the resistive anisotropy $σ_{ab}/σ_c$ and the ratio of the phase coherence lengths in the respective directions. We explore the model-independent consequences of a general assumption that the out-of-plane phase coherence length of single electrons is a short fixed distance of the order of interlayer spacing. Several topics are discussed: application of the scaling theory, magnetoresistivity, the effects of substitutions and the intermediate regime of conduction when both coherence lengths change with temperature, but at different rate.

description: We revisit the predictions for the merger rate of massive black hole binaries detectable by the Laser Interferometer Space Antenna (LISA) and their background signal for pulsar-timing arrays. We focus on the effect of the delays between the merger of galaxies and the final coalescence of black hole binaries, and on supernova feedback on the black hole growth. By utilizing a semi-analytic galaxy formation model, not only do we account for the driving the evolution of binaries at separations $\lesssim 1$ pc (gas-driven migration, stellar hardening and triple/quadruple massive black hole systems), but we also improve on previous studies by accounting for the time spent by black hole pairs from kpc down to pc separation. We also include the effect of supernova feedback, which may eject gas from the nuclear region of low-mass galaxies, thus hampering the growth of black holes via accretion and suppressing their orbital migration in circumbinary disks. Despite including these novel physical effects, we predict that the LISA detection rate should still be $\gtrsim 2 \mbox{yr}^{-1}$, irrespective of the model for the black hole seeds at high redshifts. Scenarios where black holes form from $\sim100 M_\odot$ seeds are more significantly impacted by supernova feedback. We also find that for detectable events, the merging black holes typically have mass ratios between $\sim 0.1$ and $1$. Predictions for the stochastic background in the band of pulsar-timing array experiments are instead rather robust, and show only a mild dependence on the model.

Numerical Contractor Renormalization applied to strongly correlated systems
Creators: name: Capponi, Sylvain
Publisher: name: arXiv
Year: 2005
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We demonstrate the utility of effective Hamilonians for studying strongly correlated systems, such as quantum spin systems. After defining local relevant degrees of freedom, the numerical Contractor Renormalization (CORE) method is applied in two steps: (i) building an effective Hamiltonian with longer ranged interactions up to a certain cut-off using the CORE algorithm and (ii) solving this new model numerically on finite clusters by exact diagonalization and performing finite-size extrapolations to obtain results in the thermodynamic limit. This approach, giving complementary information to analytical treatments of the CORE Hamiltonian, can be used as a semi-quantitative numerical method to study frustrated magnets (as the S=1/2 kagome lattice) or doped systems.

title: Dans la marge du hors-champ : le corps cinématographié de la femme par Claudia Llosa
Creators: name: Casimiro, Dominique
Publisher: name: Savoirs en prisme
Year: 2020

description: Le cinéma de la péruvienne Claudia Llosa (Lima, 1976) cadre le corps de la femme. Et l’histoire de ce cinéma pourrait se résumer comme le désir de ce corps d’être cadré – mais aussi comme sa résistance à se soumettre tout entier à la discipline du cadrage. Car le cadre est une pression que le corps cinématographié de la femme désire mais aussi subit. Les bords du cadre, qui séparent le visible du non-visible, sont les agents de cette lutte du corps de la femme dans les cadres, comme dans la société péruvienne actuelle. Entrant et sortant du cadre, le corps de la femme affirme les enjeux du hors-champ. Il s’agit donc de reprendre la trajectoire cinématographique de Claudia Llosa comme une histoire politique au plus près du corps de la femme, de sa soumission ou de sa liberté. Du corps acteur comme du corps spectateur : l’un et l’autre invités à la liberté du hors-champ, à ne pas tout céder à l’empire du spectacle et aux exigences de l’œil. Telle serait, en résumé, la problématique du cinéma de cette jeune cinéaste, auteure de 3 longs métrages (Madeinusa de 2005, La teta asustada de 2009 et Aloft de 2014) et deux courts (El niño Pepita de 2010 et Loxoro de 2011).

description: We present a new method, based on Gaussian process regression, for reconstructing the continuous $x$-dependence of parton distribution functions (PDFs) from quasi-PDFs computed using lattice QCD. We examine the origin of the unphysical oscillations seen in current lattice calculations of quasi-PDFs and develop a nonparametric fitting approach to take the required Fourier transform. The method is tested on one ensemble of maximally twisted mass fermions with two light quarks. We find that with our approach oscillations of the quasi-PDF are drastically reduced. However, the final effect on the light-cone PDFs is small. This finding suggests that the deviation seen between current lattice QCD results and phenomenological determinations cannot be attributed solely on the Fourier transform.

The chemistry of the Olympic Dam concentrate leaching process and viability of reductive leaching
Creators: name: Lung, Felix
Publisher: name: University of British Columbia
Year: 2009

description: The WMC Olympic Dam currently mines ore containing chalcocite, bornite, and hematite. The ore is expected to downgrade from chalcocite/bornite to chalcopyrite in the future. The result is increased strain on the direct smelter to blister process currently in operation and a necessary change to a two-step smelter-converter process. The chemistry of the concentrate leaching process was studied with the purpose of applying a reductive leach to enrich the concentrate. Enrichment increases the Cu:S ratio and would allow the current smelting process to continue in the future. Reductive leaching was conducted in acid sulfate media with iron reductant and WMC concentrate over a range of acidity (0.15 M - 0.60 M), reductant to chalcopyrite ratio (0.5 - 2.1), temperature range (25°C - 70°C), and % solids (4 % - 20 %). Select tests were repeated on chalcopyrite and a mixture of chalcopyrite and hematite for comparison. When hematite was present, reduction was modestly successful and most of the iron was consumed by side reactions within the first 10 minutes. Leaching with just chalcopyrite produced much better results. Copper reductant was used but produced minimal results unless high acidity and temperature were applied. Copper was consumed in hematite reduction as well. 77% of the hematite in WMC concentrate was removed by treating the concentrate in 200 g/L sulfuric acid at 90°C over 24 hours. Reductive leaching after this treatment should be investigated as a two-stage process.
Dutton, Davies, and Imaginative Virtual Worlds: The Current State of Evolutionary Aesthetics
Creators: name: Carroll, Joseph
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2013

description: This paper is a commentary comparing the evolutionary perspectives of Denis Dutton’s The Art Instinct (2009) and Stephen Davies’s The Artful Species (2012). Their topics thus necessarily overlap, but their books have different purposes and a different feel. Davies’s book is an academic exercise. He has no real arguments or claims of his own. Dutton wishes to demonstrate that evolutionary psychology can provide a satisfying naturalistic explanation of aesthetic experience. Neither Davies nor Dutton fully succeeds in his ambition. Davies extends his scepticism well beyond a sensible account of the state of current knowledge about human evolution, and Dutton fails to recognize underlying theoretical differences in his main sources of theoretical inspiration. The limitations in these two works do not define the boundaries of current knowledge in evolutionary aesthetics. The most advanced and adequate concept in the evolutionary humanities is the idea that humans evolved the capacity to create imaginative virtual worlds and use those worlds to guide human behaviour. Both books being considered in this essay approach the idea of imaginative virtual worlds and almost grasp it. Before taking up that topic, the paper shall discuss two subsidiary issues: Dutton’s effort to incorporate sexual selection, and Davies’s sceptical negations about all evolutionary knowledge.

description: CERN-LHC. Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb$^{-1}$ of $\sqrt{s}=8$ TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with $p_T > 120$ GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between $E_T^{miss} > 150$ GeV and $E_T^{miss} > 700$ GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with large extra spatial dimensions, pair production of weakly interacting dark matter candidates, and production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presented.

description: Stability, bifurcation properties, and the spatiotemporal behavior of different nonlinear combination structures of spiral vortices in the counter rotating Taylor-Couette system are investigated by full numerical simulations and by coupled amplitude equation approximations. Stable cross-spiral structures with continuously varying content of left and right spiral modes are found. They provide a stability transferring connection between the initially stable, axially counter propagating wave states of pure spirals and the axially standing waves of so-called ribbons that become stable slightly further away from onset of vortex flow.
