Extended 2d generalized dilaton gravity theories

description: We show that an anomaly-free description of matter in (1+1) dimensions requires a deformation of the 2d relativity principle, which introduces a non-trivial center in the 2d Poincare algebra. Then we work out the reduced phase-space of the anomaly-free 2d relativistic particle, in order to show that it lives in a noncommutative 2d Minkowski space. Moreover, we build a Gaussian wave packet to show that a Planck length is well-defined in two dimensions. In order to provide a gravitational interpretation for this noncommutativity, we propose to extend the usual 2d generalized dilaton gravity models by a specific Maxwell component, which gauges the extra symmetry associated with the center of the 2d Poincare algebra. In addition, we show that this extension is a high energy correction to the unextended dilaton theories that can affect the topology of space-time. Further, we couple a test particle to the general extended dilaton models with the purpose of showing that they predict a noncommutativity in curved space-time, which is locally described by a Moyal star product in the low energy limit. We also conjecture a probable generalization of this result, which provides a strong evidence that the noncommutativity is described by a certain star product which is not of the Moyal type at high energies. Finally, we prove that the extended dilaton theories can be formulated as Poisson-Sigma models based on a nonlinear deformation of the extended Poincare algebra.

ADABOOK & MULTIBOOK: Adaptive Boosting with Chance Correction

description: There has been considerable interest in boosting and bagging, including the combination of the adaptive techniques of AdaBoost with the random selection with replacement techniques of Bagging. At the same time there has been a revisiting of the way we evaluate, with chance-corrected measures like Kappa, Informedness, Correlation or ROC AUC being advocated. This leads to the question of whether learning algorithms can do better by optimizing an appropriate chance corrected measure. Indeed, it is possible for a weak learner to optimize Accuracy to the detriment of the more reaslistic chance-corrected measures, and when this happens the booster can give up too early. This phenomenon is known to occur with conventional Accuracy-based AdaBoost, and the MultiBoost algorithm has been developed to overcome such problems using restart techniques based on bagging. This paper thus complements the theoretical work showing the necessity of using chance-corrected measures for evaluation, with empirical work showing how use of a chance-corrected measure can improve boosting. We show that the early surrender problem occurs in MultiBoost too, in multiclass situations, so that chance-corrected AdaBook and Multibook can beat standard Multiboost or AdaBoost, and we further identify which chance-corrected measures to use when.

Topologies of place: a building in the landscape
Creators: name: Meissner, Brian August
Publisher: name: University of British Columbia
Year: 2009

description: Sited on the bed of an ancient rail spur within the now abandoned plat of East Princeton, British Columbia, this project consists of two unprogrammed buildings constructed using a palette of physical and poetic materials which emerge from a deep understanding of a particular site. The project begins with the assumption that cultural process is an amazing energy which does not require architecture specifically. Architecture may, however, provide a catalyst for cultural/ social dynamic and can provide a medium for its expression. Explorations undertaken are dependent upon an idea of place as an intersection of social, economic, political, historical, and physical relations within a kind of topological space. In the context of a particular site and through studies of a layering of conditions present at a precise point in time, this idea of place is used to uncover specific interactions between myth, persons, artifacts, and other factors which help lay the framework for a building in the landscape. Most importantly the project is about personal design process and discovery. Throughout the study the project is very much in control of the author with each stage of the study generating its own operating agenda. Thus an idea about the limits of architecture leads to a condition of site which itself leads to a particular map and finally to a highly specific site. Likewise program is allowed to emerge from studies of the site so that building and the desire to build become the catalyst for program rather than vise-versa. As these explorations intersect and overlap they begin to reveal a topology of place which is highly specific, but which contains links to an infinite set of other relationships and possibilities. Thus, architecture is employed as a catalyst for place expression, or as an avenue towards understanding place.

description: Nowadays, compact sources like surfaces of nearby stars, circumstellar environments of stars from early stages to the most evolved ones and surroundings of active galactic nuclei can be investigated at milli-arcsecond scales only with the VLT in its interferometric mode. We propose a spectro-imager, named VSI (VLTI spectro-imager), which is capable to probe these sources both over spatial and spectral scales in the near-infrared domain. This instrument will provide information complementary to what is obtained at the same time with ALMA at different wavelengths and the extreme large telescopes.

description: Spin-orbit coupling in two-dimensional systems is usually characterized by Rashba and Dresselhaus spin-orbit coupling (SOC) linear in the wave vector. However, there is a growing class of materials which instead support dominant SOC cubic in the wave vector (cSOC), while their superconducting properties remain unexplored. By focusing on Josephson junctions in Zeeman field with superconductors separated by a normal cSOC region, we reveal a strongly anharmonic current-phase relation and complex spin structure. An experimental cSOC tunability enables both tunable anomalous phase shift and supercurrent, which flows even at the zero-phase difference in the junction. A fingerprint of cSOC in Josephson junctions is the f-wave spin-triplet superconducting correlations, important for superconducting spintronics and supporting Majorana bound states.

Measurement of inelastic J/psi production in deep inelastic scattering at HERA
Creators: name: ZEUS Collaboration
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The inelastic production of J/psi mesons in e p collisions has been studied with the ZEUS detector at HERA using an integrated luminosity of 109 pb-1. The J/psi mesons were identified using the decay channel J/psi -> mu+ mu-. The measurements were performed in the kinematic range 2 < Q^2< 80 Gev^2, 50 < W < 250 Gev, 0.2 < z <0.9 and -1.6 < Ylab < 1.3, where Q^2 is the virtuality of the exchanged photon, W is the photon-proton centre-of-mass energy, z is the fraction of the photon energy carried by the J/psi meson in the proton rest frame and Ylab is the rapidity of the J/psi in the laboratory frame. The measured cross sections are compared to theoretical predictions within the non-relativistic QCD framework including colour-singlet and colour-octet contributions, as well as to predictions based on the kT-factorisation approach. Calculations of the colour-singlet process generally agree with the data, whereas inclusion of colour-octet terms spoils this agreement.

description: Recent follow-up observations of the December 27 giant flare of SGR 1806-20 have detected a multiple-frequency radio afterglow from 240 MHz to 8.46 GHz, extending in time from a week to about a month after the flare. The angular size of the source was also measured for the first time. Here we show that this radio afterglow gives the first piece of clear evidence that an energetic blast wave sweeps up its surrounding medium and produces a synchrotron afterglow, the same mechanism as established for gamma-ray burst afterglows. The optical afterglow is expected to be intrinsically as bright as $m_R\simeq13$ at $t\la 0.1$ days after the flare, but very heavy extinction makes the detection difficult because of the low galactic latitude of the source. Rapid infrared follow-up observations to giant flares are therefore crucial for the low-latitude SGRs, while for high-latitude SGRs (e.g. SGR 0526-66), rapid follow-ups should result in identification of their possible optical afterglows. Rapid multi-wavelength follow-ups will also provide more detailed information of the early evolution of a fireball as well as its composition.

description: Matter distribution around clusters is highly anisotropic from their being the nodes of the cosmic web. Clusters' shape and the number of filaments they are connected to, i.e., their connectivity, should reflect their level of anisotropic matter distribution and must be, in principle, related to their physical properties. We investigate the influence of the dynamical state and the formation history on both the morphology and local connectivity of about 2400 groups and clusters of galaxies from the large hydrodynamical simulation IllustrisTNG at z=0. We find that the mass of groups and clusters mainly influences the geometry of the matter distribution: massive halos are significantly more elliptical, and more connected to the cosmic web than low-mass ones. Beyond the mass-driven effect, ellipticity and connectivity are correlated and are imprints of the growth rate of groups and clusters. Both anisotropy measures appear to trace different dynamical states, such that unrelaxed groups and clusters are more elliptical and more connected than relaxed ones. This relation between matter anisotropies and dynamical state is the sign of different accretion histories. Relaxed groups and clusters are mostly formed long time ago, and slowly accreting matter at the present time. They are rather spherical and weakly connected to their environment, mostly because they had enough time to relax and, hence, lost the connection with their preferential directions of accretion and merging. In contrast, late-formed unrelaxed objects are highly anisotropic with large connectivities and ellipticities. These groups and clusters are in formation phase and must be strongly affected by the infalling of materials from filaments.

Co-Production and Co-Creation

description: Over the past decade, co-production and co-creation have become central buzzwords throughout society. The terms engender a fundamental participatory ethos, entailing an increasing involvement in decision-making processes of a variety of people across diverse contexts, who should be given a voice in a wide range of practices to a higher degree than previously done. To a large extent, this participatory wave thus creates new challenges and dilemmas for employees in contemporary organizations. For instance, many public employees (frontline workers) experience challenges regarding translating (and/or enacting) co-creative/co-productive policy objectives into (in) their practices. A central obstacle seems to be the fact that existing organizational frameworks and conditions are often rooted in contradictory management paradigms and reified institutionalized practices, complicating participatory aspirations and processes in various ways. In different ways, the contributions in this issue critically address and discuss a variety of challenges related to co-production and co-creation in contemporary society.

Novel elastic instability of amorphous solids in finite spatial dimensions

description: Recently, progress has been made in the understanding of anomalous vibrational excitations in amorphous solids. In the lowest-frequency region, the vibrational spectrum follows a non-Debye quartic law, which persists up to zero frequency without any frequency gap. This gapless vibrational density of states (vDOS) suggests that glasses are on the verge of instability. This feature of marginal stability is now highlighted as a key concept in the theories of glasses. In particular, the elasticity theory based on marginal stability predicts the gapless vDOS. However, this theory yields a quadratic law and \textit{not} the quartic law. To address this inconsistency, we presented a new type of instability, which is different from the conventional one, and proposed that amorphous solids are marginally stable considering the new instability in the preceding study~[M. Shimada, H. Mizuno, and A. Ikeda, Soft Matter, {\bf 16}, 7279, 2020]. In this study, we further extend and detail the results for these instabilities. By analyzing various examples of disorder, we demonstrate that real glasses in finite spatial dimensions can be marginally stable by the proposed novel instability.

description: We distinguish two general modes of testing for Deep Neural Networks (DNNs): Offline testing where DNNs are tested as individual units based on test datasets obtained without involving the DNNs under test, and online testing where DNNs are embedded into a specific application environment and tested in a closed-loop mode in interaction with the application environment. Typically, DNNs are subjected to both types of testing during their development life cycle where offline testing is applied immediately after DNN training and online testing follows after offline testing and once a DNN is deployed within a specific application environment. In this paper, we study the relationship between offline and online testing. Our goal is to determine how offline testing and online testing differ or complement one another and if offline testing results can be used to help reduce the cost of online testing? Though these questions are generally relevant to all autonomous systems, we study them in the context of automated driving systems where, as study subjects, we use DNNs automating end-to-end controls of steering functions of self-driving vehicles. Our results show that offline testing is less effective than online testing as many safety violations identified by online testing could not be identified by offline testing, while large prediction errors generated by offline testing always led to severe safety violations detectable by online testing. Further, we cannot exploit offline testing results to reduce the cost of online testing in practice since we are not able to identify specific situations where offline testing could be as accurate as online testing in identifying safety requirement violations.

description: Results from helically symmetric scalar field models and first results from a convergent helically symmetric binary neutron star code are reported here; these are models stationary in the rotating frame of a source with constant angular velocity omega. In the scalar field models and the neutron star code, helical symmetry leads to a system of mixed elliptic-hyperbolic character. The scalar field models involve nonlinear terms that mimic nonlinear terms of the Einstein equation. Convergence is strikingly different for different signs of each nonlinear term; it is typically insensitive to the iterative method used; and it improves with an outer boundary in the near zone. In the neutron star code, one has no control on the sign of the source, and convergence has been achieved only for an outer boundary less than approximately 1 wavelength from the source or for a code that imposes helical symmetry only inside a near zone of that size. The inaccuracy of helically symmetric solutions with appropriate boundary conditions should be comparable to the inaccuracy of a waveless formalism that neglects gravitational waves; and the (near zone) solutions we obtain for waveless and helically symmetric BNS codes with the same boundary conditions nearly coincide.

The bases for this algebra are indexed by set partitions. We show that there exist a natural inclusion of the Hopf algebra of noncommutative symmetric functions indexed by compositions in this larger space. We also consider this algebra as a subspace of noncommutative polynomials and use it to understand the structure of the spaces of harmonics and coinvariants with respect to this collection of noncommutative polynomials.

description: An increased knowledge of innovation depends on high-quality research. However, what aspects of innovation impact positive outcomes for different actors? New insights call for the development of research methodology to be used to explore and investigate the phenomenon of innovation, i.e., processes and outcomes. In this paper, our aims are to a) describe the development of a conceptual model of social innovation at the micro level and b) describe the development of a quantitative methodology named the Social Innovation Measurement Model Questionnaire (SIMM-Q). We will also discuss some principal issues linked to research on social innovation and its relevance for co-creation.

description: Co-creation of public services calls for new leadership actions putting a strong demand on leaders in traditional bureaucratic organizations. This study explores critical leadership actions enabling co-creation in cross-institutional partnerships. The study is based on data from a co-creation project in a cross-institutional university-school partnership. The project leader and the innovation leader have key roles in the partnership’s infrastructure. Using complexity leadership theory as a theoretical lens, the paper examines how the leaders developed an inter-institutional network enabling 14 collaborative R&D projects between researchers and teachers. The study suggests that formal and informal leadership actions aimed at creating cross-institutional managerial commitment, supporting emerging semi-structured planning, developing a broad targeted information strategy, and connecting people across institutions are vital for enabling co-creation in cross-institutional partnerships.

However, in museum literature, collaborative projects have often been evaluated in terms of their overall perspectives and outcomes, rather than discussing how the collaborative and co-creative efforts are shaped and feed into the designs. Therefore, this paper suggests an initial framework for understanding and discussing collaborative constellations and co-creative processes in museum experience design, by presenting a Venn diagram. This builds on a case study of three recent collaborative constellations between designers, museum professionals and museum visitors.

description: We establish the theoretical feasibility of direct analog simulation of the compact U(1) lattice gauge theories in optical lattices with dipolar bosons. We discuss the realizability of the topological Coulomb phase in extended Bose-Hubbard models in several optical lattice geometries. We predict the testable signatures of this emergent phase in noise correlation measurements, thus suggesting the possible emergence of artificial light in optical lattices.

Social research at a time of fast feedback and rapid change

description: This contribution offers a reflection on the shift in social science towards participative enquiry and collaborative research practices. In doing so, the paper challenges the common conception that the methodological indeterminacy that participatory research may occasion undermines its scientific credentials by rendering its processes and outcomes vulnerable to idiosyncratic events, subjective interpretations, local variability and chancy outcomes. The focus of the article is not just that participatory processes require research flexibility to enhance the pragmatic outcomes of research, but that the researcher’s theory and methodology may need to be recalibrated from discipline-controlled givens to publicly-negotiable points of departure. This latter point expands the paper’s argument to advocate for research that has “the power to be affected” (Hardt 2007, x) by the views, feelings and experiences of those it targets, and of those affected by its processes and conclusions. Using video-reflexive ethnography to illustrate this point, the article exemplifies what it means for the researcher(s) to be affected by the constraints inherent in their own research approach and disciplinary priorities (Iedema 2021).

description: Aim: This study aimed to evaluate the anti-anxiety activity of the Methanolic extract, and chloroform extract of Lannea coromandelica leaves in mice using an animal model. Methods: Psychopharmacological studies present antioxidants as a potential new strategy for the treatment of anxiety. The present paper deals with a preliminary phytochemical evaluation of the leaf Lannea coromandelica to establish anti-anxiety activity. Result: The study includes the preparation of different extracts and their phytochemical analysis and biological activity. Phytochemical studies revealed the presence of saponins, tannins, phenolics, terpenoids, and steroids. In the present investigation, Methanolic extract at 500 (µg/ml) showed 44.11% Scavenging effect & Chloroform extract at 500 (µg/ml) showed 51.47 %. These extracts showed moderate radical scavenging activity in the DPPH assay. This may be attributable to the high total phenolic and total flavonoid contents of the extracts. Elevated plus maze test was used to assess the psychomotor performance and emotional aspects of mice, treatment with Methanolic extract, and chloroform extract revealed anxiolytic activity, since the number of open arm entries and time spent in open arm parameters are the most delegated guide for anxiolytic activity Discussion: In our study, we demonstrated significant anti-anxiety activity with 500mg of both extracts compared to control group but has less activity when compared to that of diazepam but both were statistically significant. The average of basal activity scores in the control group after 30 and 60 minutes of administration of Methanolic, chloroform extracts of Lannea coromandelica leaves 500 mg/kg p.o. significantly reduced locomotor activity. Conclusion: It may be due to the CNS depressant property of the drug. The time spent by the animal in the central platform seems to be related to decision-making or risk assessment and the total arm entries is a measure reflecting changes in anxiety.

The Economics of Variable Renewables and Electricity Storage

description: The transformation of the electricity sector is a main element of the transition to a decarbonized economy. Conventional generators powered by fossil fuels have to be replaced by variable renewable energy (VRE) sources in combination with electricity storage and other options for providing temporal flexibility. We discuss the market dynamics of increasing VRE penetration and their integration in the electricity system. We describe the merit-order effect (decline of wholesale electricity prices as VRE penetration increases) and the cannibalization effect (decline of VRE value as their penetration increases). We further review the role of electricity storage and other flexibility options for integrating variable renewables, and how storage can contribute to mitigating the two mentioned effects. We also use a stylized open-source model to provide some graphical intuition on this. While relatively high shares of VRE are achievable with moderate amounts of electricity storage, the role of long-term storage increases as the VRE share approaches 100%.
Directional Statistics for WIMP direct detection II: 2-d read-out

description: The direction dependence of the WIMP direct detection rate provides a powerful tool for distinguishing a WIMP signal from possible backgrounds. We study the the number of events required to discriminate a WIMP signal from an isotropic background for a detector with 2-d read-out using non-parametric circular statistics. We also examine the number of events needed to i) detect a deviation from rotational symmetry, due to flattening of the Milky Way halo and ii) detect a deviation in the mean direction due to a tidal stream. If the senses of the recoils are measured then of order 20-70 events (depending on the plane of the 2-d read out) will be sufficient to reject isotropy of the raw recoil angles at 90% confidence. If the senses can not be measured these number increase by roughly two orders of magnitude (compared with an increase of one order of magnitude for the case of full 3-d read-out). The distributions of the reduced angles, with the (time dependent) direction of solar motion subtracted, are far more anisotropic, however, and if the isotropy tests are applied to these angles then the numbers of events required are similar to the case of 3-d read-out. A deviation from rotational symmetry will only be detectable if the Milky Way halo is significantly flattened. The deviation in the mean direction due to a tidal stream is potentially detectable, however, depending on the density and direction of the stream.

description: The article is based on two PhD studies in which marginalized co-researchers who depend on the aid apparatus contribute to co-creation of research. The first study includes parents whose children are placed in public care; the other study includes homeless people. In the article, we want to explore the co-creation process between researchers and co-researchers in research where the co-researchers have a background from marginalized groups that depend on the aid apparatus. Findings from our studies indicate that such a dependency can act as a barrier to critical research or critical actions in two ways: 1) It is difficult to be critical of one’s own position, and 2) It is difficult to be critical to the aid apparatus. The article concludes that the two positions are different but that they serve the same purpose: it is strategic to position oneself in certain ways when a lot is at stake.

Samskaping som revitalisering av samfunnsarbeid i sosialt arbeid – mulighet eller blindspor?

description: From being an important approach in the 1970s community work today has a weakened position in social work. Individual oriented positions dominate. The development could be seen as paradoxical since the term co-creation simultaneously has obtained a prominent position in welfare policy. However, even if both concepts share the prefix “co”, the terms have very different backgrounds. Community work has its roots in a bottom-up perspective and a left-wing ideology. The co-creation approach has its background in innovation literature where it has moved from the private to the public sector and is mainly introduced by the state authorities. Besides expressing democratic intentions co-creation is also associated with the goals of efficiency and increased sustainability in the welfare area. The article will discuss whether the co-creatin concept might contribute to a revitalisation of community work or if such a strategy would imply a dead end if the original intentions of community work should be sustained.

description: Successive magnetic-field-induced charge-density-wave transitions in the molecular conductor $α$-(BEDT-TTF)$_2$KHg(SCN)$_4$ are studied in the hydrostatic pressure regime, in which the zero field charge-density wave (CDW)state is completely suppressed. The orbital effect of the magnetic field is demonstrated to restore the density wave, while the orbital quantization induces different CDW states in different field intervals. In particular, we have found that at certain field orientations the hysteretic first order transitions between field-induced CDW subphases become visible at much higher temperatures. This observation is very well in line with the existing theories of field-induced CDW transitions.

description: Inspections were conducted on bridge modular expansion joints and deck drains to assess their performance. Forty-four modular expansion joints were inspected including 38 Wabo-Maurer and 16 Acme joints. Twenty-three elastomeric dams were also inspected for comparative purposes including 21 Transflex dams and 2 Fei-Span units. The joints were rated using a quantitative subjective rating system developed by Penn DOT.  Both the modular expansion joints and the newer expansion dams were performing satisfactorily. Both types of joints leaked and experienced a number of minor hardware problems. some of the joints may warrant repairs to restore their complete function.  Deck drains and drain outlet piping systems were inspected. The deck drains inspected included those having square and rectangular inlets, pipe drains, and scuppers (edge drains).  All types of deck drains appear susceptible to clogging. Large scuppers performed well. Also, simple straight drop pipes were less clog prone than complex piping systems. Recommendations are provided to minimize clogging problems.
