description: In this paper, we develop a theory about the relationship between invariant and equivariant maps with regard to a group $G$. We then leverage this theory in the context of deep neural networks with group symmetries in order to obtain novel insight into their mechanisms. More precisely, we establish a one-to-one relationship between equivariant maps and certain invariant maps. This allows us to reduce arguments for equivariant maps to those for invariant maps and vice versa. As an application, we propose a construction of universal equivariant architectures built from universal invariant networks. We, in turn, explain how the universal architectures arising from our construction differ from standard equivariant architectures known to be universal. Furthermore, we explore the complexity, in terms of the number of free parameters, of our models, and discuss the relation between invariant and equivariant networks' complexity. Finally, we also give an approximation rate for G-equivariant deep neural networks with ReLU activation functions for finite group G.

description: Within the framework of the nonrelativistic QCD (NRQCD) factorization approach, we compute the polarization of prompt J/psi produced at the Brookhaven's Relativistic Heavy-Ion Collider from proton-proton collisions at the center-of-momentum energy sqrt{s}=200 GeV. The perturbative contributions are computed at leading order in the strong coupling constant. The prediction reveals that the color-singlet contribution severely underestimates the PHENIX preliminary data for the differential cross section integrated over the rapidity range |y|<0.35 and its contribution is strongly transversely polarized, which disagrees with the PHENIX preliminary data. After including the color-octet contributions, we find that the NRQCD predictions for both the cross section and polarization over the transverse-momentum range 1.5 GeV < p_T < 5 GeV (1.5 GeV < p_T < 2 GeV) integrated over the rapidity range |y|<0.35 (1.2 < |y| < 2.2) agree with the data within errors.

description: The population of Hungary, similar to the European countries, shows an ageing tendency. The life expectancy at birth and after 65 is growing, as a consequence of which the increased years of life can become meaty besides adequate life quality. An important related area is activity and sports. Accordingly, it can become a priority task to involve the older generations into sport consumption and sport tourism. In their study the authors examine the connections between the attitudes toward sports and sport tourism among the Hungarian population with particular regard to the 50-70 years old people. Based on the results of the survey, carried out within the framework of the project EFOP-3.6.2-16-2017-003: “Cooperative Research Network in Economy of Sport, Recreation and Health”, focusing on the sport consumption habits of the Hungarian population the sport-attitudes and travels by reason of sport of the elderly cohorts are demonstrated. On this basis proposals, sports and public health programmes and sports tourism projects can be drafted, which could level up the consumption and activities of the elderly to a higher level.
Motion Control of a Semi-mobile Haptic Interface for Extended Range Telepresence
Creators: name: Pérez Arias, Antonia

Publisher: name: Karlsruhe
Year: 2011

description: This paper presents the control concept of a semimobile haptic interface for extended range telepresence that enables the user to explore spatially unrestricted target environments even from a small user environment. The semi-mobile haptic interface consists of a haptic manipulator mounted on a large grounded Cartesian robot, the prepositioning unit. The prepositioning unit is controlled in such a way that the haptic manipulator is kept off its workspace limits. At the same time, the control algorithm allows the optimal utilization of the available space in the user environment and guarantees the safety of the user. The proposed control method is based on the position and velocity of the end-effector and also takes the position of the user into account. Moreover, it is robust against noisy measurements of the user position or outliers due, for example, to occlusions in the tracking system. Experimental results show the suitability of the proposed control to provide haptic interaction in extended range telepresence.

description: Calculating a Monte Carlo standard error (MCSE) is an important step in the statistical analysis of the simulation output obtained from a Markov chain Monte Carlo experiment. An MCSE is usually based on an estimate of the variance of the asymptotic normal distribution. We consider spectral and batch means methods for estimating this variance. In particular, we establish conditions which guarantee that these estimators are strongly consistent as the simulation effort increases. In addition, for the batch means and overlapping batch means methods we establish conditions ensuring consistency in the mean-square sense which in turn allows us to calculate the optimal batch size up to a constant of proportionality. Finally, we examine the empirical finite-sample properties of spectral variance and batch means estimators and provide recommendations for practitioners.

The Madrid Protocol and beyond: Strategies for marine conservation in the high seas and Southern Ocean
Creators: name: Harris, JW
Publisher: name: University Of Tasmania
Year: 2023

description: The establishment of Marine Protected Areas (MPAs) on the high seas has recently emerged on the international agenda as a critical issue requiring the integration of novel approaches, international cooperation and political will. Since the high seas are subject to open access, the rights and obligations of States on the high seas can be ambiguous and confusing. There is a need to clarify how high seas marine conservation can be implemented under international law and in the Antarctic, both within and beyond the instruments of the Antarctic Treaty System (ATS). In recent years, Antarctic Treaty Consultative Parties have pondered the application of alternative international approaches and instruments in the region. This study seeks to contribute to this debate, assessing the ATS and key international instruments and approaches regarding their applicability to the high seas, comprehensiveness (assessed by species, in-situ or ex-situ conservation measures), progressiveness (application of the ecosystem or precautionary approach) and their legal status (soft or hard law, entry into force, Contracting Parties). Site selection for Southern Ocean MPAs is hindered by a lack of data on marine biodiversity. This study uses seabirds as surrogates for marine biodiversity. Drawing on a 20-year database comprising over 140,000 'at sea' seabird sightings, this study assesses the potential use of seabirds as surrogates for marine biodiversity in the Indian sector of the Southern Ocean. Surrogate indices used were species density, richness, IUCN status and Shannon-Weaver diversity. The seabird observations were aggregated into 1¬¨‚àû (n = 1952), 2¬¨‚àû (n = 704) and 5¬¨‚àû bins (ri = 177). Surrogates were classified as high, medium or low, with 'high' areas of greatest conservation value. The study identified 22 urgent priority areas where conservation action appears justified, with clusters near Heard and McDonald Islands, and Isles Crozet. Integrating policy with science and considering area selection techniques provides an objective contribution to Antarctic conservation planning. Antarctic marine conservation is best managed within the ATS, with strong involvement from the Commission for the Conservation of Antarctic Marine Living Resources. The ATS could, however be strengthened by applying the principles and approaches used by key international instruments, particularly the Convention on Biological Diversity and the United Nations Convention on the Law of the Sea. The use of seabirds as surrogates has value in Antarctic conservation planning, but additional species or environmental data would improve the process.

description: A combination of a telepresence system and a microscopic traffic simulator is introduced. It is evaluated using a hotel evacuation scenario. Four different kinds of supporting information are compared, standard exit signs, floor plans with indicated exit routes, guiding lines on the floor and simulated agents leading the way. The results indicate that guiding lines are the most efficient way to support an evacuation but the natural behavior of following others comes very close. On another level the results are consistent with previously performed real and virtual experiments and validate the use of a telepresence system in evacuation studies. It is shown that using a microscopic traffic simulator extends the possibilities for evaluation, e.g. by adding simulated humans to the environment.
(Semi-)Analytic Gaussian Mixture Filter

Publisher: name: Karlsruhe
Year: 2011

description: In nonlinear filtering, special types of Gaussian mixture filters are a straightforward extension of Gaussian filters, where linearizing the system model is performed individually for each Gaussian component. In this paper, two novel types of linearization are combined with Gaussian mixture filters. The first linearization is called analytic stochastic linearization, where the linearization is performed analytically and exactly, i.e., without Taylor-series expansion or approximate sample-based density representation. In cases where a full analytical linearization is not possible, the second approach decomposes the nonlinear system into a set of nonlinear subsystems that are conditionally integrable in closed form. These approaches are more accurate than fully applying classical linearization.

description: A pulsed N.M.R. spectrometer capable of operating over the frequency range 40 Mhz. to 100 Mhz. has been constructed. It was used to observe the nuclear resonance of Fe⁵⁷ in unenriched iron powder at 4.2°K. and 77°K.. Some preliminary experiments were performed and the results of these experiments are in good agreement with other reported results. This indicates that the spectrometer is suitable for use in future experiments.

description: Instruments play an essential role in creating research data. Given the importance of instruments and associated metadata to the assessment of data quality and data reuse, globally unique, persistent and resolvable identification of instruments is crucial. The Research Data Alliance Working Group Persistent Identification of Instruments (PIDINST) developed a community-driven solution for persistent identification of instruments which we present and discuss in this paper. Based on an analysis of 10 use cases, PIDINST developed a metadata schema and prototyped schema implementation with DataCite and ePIC as representative persistent identifier infrastructures and with HZB (Helmholtz-Zentrum Berlin für Materialien und Energie) and BODC (British Oceanographic Data Centre) as representative institutional instrument providers. These implementations demonstrate the viability of the proposed solution in practice. Moving forward, PIDINST will further catalyse adoption and consolidate the schema by addressing new stakeholder requirements.
The axis of evil - a polarization perspective

description: We search for an unusual alignment of the preferred axes of the quadrupole and octopole, the so-called axis of evil, in the CMB temperature and polarization data from WMAP. We use the part of the polarization map which is uncorrelated with the temperature map as a statistically independent probe of the axis of evil, which helps to assess whether the latter has a cosmological origin or if is a mere chance fluctuation in the temperature. Note, though, that for certain models creating a preferred axis in the temperature map, we would not expect to see the axis in the uncorrelated polarization map. We find that the axis of the quadrupole of the uncorrelated polarization map roughly aligns with the axis of evil within our measurement precision, whereas the axis of the octopole does not. However, with our measurement uncertainty, the probability of such a scenario to happen by chance in an isotropic universe is of the order of 50 per cent. We also find that the so-called cold spot present in the CMB temperature map is even colder in the part of the temperature map which is uncorrelated with the polarization, although there is still a large uncertainty in the latter. Therefore, our analysis of the axis of evil and a future analysis of the cold spot in the uncorrelated temperature data will strongly benefit from the polarization data expected from the Planck satellite.

Automatic Exploitation of Independencies for Covariance Bounding in Fully Decentralized Estimation
Creators: name: Noack, Benjamin
name: Baum, Marcus

Publisher: name: Karlsruhe
Year: 2011

description: Especially in the field of sensor networks and multi-robot systems, fully decentralized estimation techniques are of particular interest. As the required elimination of the complex dependencies between estimates generally yields inconsistent results, several approaches, e.g., covariance intersection, maintain consistency by providing conservative estimates. Unfortunately, these estimates are often too conservative and therefore, much less informative than a corresponding centralized approach. In this paper, we provide a concept that conservatively decorrelates the estimates while bounding the unknown correlations as closely as possible. For this purpose, known independent quantities, such as measurement noise, are explicitly identified and exploited. Based on tight covariance bounds, the new approach allows for an intuitive and systematic derivation of appropriate tailor-made filter equations and does not require heuristics. Its performance is demonstrated in a comparative study within a typical SLAM scenario.
Shape Tracking of Extended Objects and Group Targets with Star-Convex RHMs
Creators: name: Baum, Marcus
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2011

description: This paper is about tracking an extended object or a group target, which gives rise to a varying number of measurements from different measurement sources. For this purpose, the shape of the target is tracked in addition to its kinematics. The target extent is modeled with a new approach called Random Hypersurface Model (RHM) that assumes varying measurement sources to lie on scaled versions of the shape boundaries. In this paper, a star-convex RHM is introduced for tracking star-convex shape approximations of targets. Bayesian inference for star-convex RHM is performed by means of a Gaussian-assumed state estimator allowing for an efficient recursive closed-form measurement update. Simulations demonstrate the performance of this approach for typical extended object and group tracking scenarios.

A kapott eredmények azt igazolják, hogy a fitneszszolgáltatók az alap és kiegészítő szolgáltatásaikban törekednek az extenzív és intenzív fejlesztésre egyaránt, ami azt eredményezi, hogy a kínálatukban elég szép számban szerepeltetnek kondicionálótermi gépeket, többféle csoportos óra megtartására alkalmas légkondicionált termeket, parkolókat, wellness-szolgáltatásokat is kínálnak, melyek a fogyasztói fitnesztrendekhez igazodnak. ----------- With healthy lifestyle getting more widespread, demand for sports services is growing among health-conscious consumers as well. The present study was conducted among fitness service providers (n = 11) in Debrecen. During our research we sought to find out how these service providers develop their supply elements and are these elements in line with the demand trends? Semi-structured interviews were analyzed by content analysis, which were partially processed using Excel software. Mean and standard deviation were calculated when evaluating the results. The results show that the fitness service providers strive for both extensive and intensive development in their basic and ancillary services, which results in a fairly large number of fitness equipment, air-conditioned rooms suitable for group trainings, parking lots and wellness services that are tailored to consumer fitness trends.

description:
 Crisper protein structures are short palindromic replications of regular clusters, and their associated proteins (CRISPR / Cas) were first identified in E. coli in 1987, which identified prokaryotic cells against any invasive, harmful pathogens and plasmids were protected. Several genome editing approaches have been used based on these mechanisms. The most recent of these is known as CRISPR / Cas, which has attracted much attention in the scientific community, especially for the diagnosis and treatment of disease, because it is faster, cheaper, and more accurate than other genome editing methods. The unprecedented expansion of COVID-19 around the world has created new challenges. Evidence of gene mutations in specific patients and the use of CRISPR / Cas can help to predict the optimal treatment plan for patients. In addition, CRISPR / Cas provides a tool for manipulating non-coding regions, thus accelerating the study of these poorly characterized genome regions and playing a vital role in the development of entire genome libraries.
 Objective: To study the mechanisms of CRISPR techniques as a tool for studying natural mutations and genomic manipulations, and to evaluate how CRISPR / Cas works in the treatment of COVID-19

description: We develop a symplectic method of quantization of lightcone QCD. We find that boundary gauge fields are crucial for a consistent and complete quantization. By applying the symplectic Faddeev-Jackiw method, we very carefully remove unphysical degrees of freedom and obtain the true phase space and the complete Hamiltonian. The result is important for the high energy QCD evolution and for a further extension of the JIMWLK equation, for which we find the second-order correction. Finally, we make an important note about a peculiarity of four space-time dimensions. In additional, our method sheds new light on the lightcone quantization of a scalar field.

description: We report the pressure and temperature dependence of the phonon density-of-states in superconducting Ca0.6Na0.4Fe2As2 (Tc=21 K) and the parent compound CaFe2As2, using inelastic neutron scattering. We observe no significant change in the phonon spectrum for Ca0.6Na0.4Fe2As2 at 295 K up to pressures of 5 kbar. The phonon spectrum for CaFe2As2 shows softening of the low-energy modes by about 1 meV when decreasing the temperature from 300 K to 180 K. There is no appreciable change in the phonon density of states across the structural and anti-ferromagnetic phase transition at 172 K. These results, combined with our earlier temperature dependent phonon density of states measurements for Ca0.6Na0.4Fe2As2, indicate that the softening of low-energy phonon modes in these compounds may be due to the interaction of phonons with electron or short-range spin fluctuations in the normal state of the superconducting compound as well as in the parent compound. The phonon spectra are analyzed with ab-initio and empirical model calculations giving partial densities of states and dispersion relations.

description: We show that quintessence, when it is described by a tachyonic field, can amplify a tiny primordial gradient generating a preferred direction in the sky. In its simplest realization, this mechanism only affects the Cosmic Microwave Background fluctuations at the quadrupole level. We briefly discuss how higher multipoles can also be affected, once the full structure of the quintessence potential is taken into account.

description: Materials with topological electronic states have emerged as one of the most exciting discoveries of condensed quantum matter, hosting quasiparticles with extremely low effective mass and high mobility. Weyl materials contain such topological states in the bulk and additionally have a non-trivial chiral charge. However, despite known quantum effects caused by these chiral states, the interplay between chiral states, and a charge density wave phase, an ordering of the electrons to a correlated phase is not experimentally explored. Indications for the formation of a charge density wave phase in the Weyl material cobalt monosilicide CoSi are observed. Furthermore, the typical signatures of the charge density wave phase together with typical signatures of Weyl fermions in magnetic field dependent electrical transport characterization are investigated. The charge density wave and the chiral contribution to the electrical magneto-transport are separated as well as a suppression of the charge density wave phase is observed in magnetic fields. © 2019 The Authors.

Two-Loop Spectroscopy of Short ABJM Operators

Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study the spectrum of anomalous dimensions of short operators in planar ABJM theory at two loops. Specifically we develop a method for solving the OSp(6|4) Bethe ansatz equations for a certain class of unpaired length-4 states with arbitrarily high number of excitations, and apply it to identify three new sequences of rational eigenvalues. Results for low-lying paired states in the OSp(4|2) sector are obtained by direct diagonalization of the spin chain Hamiltonian. We also study the SL(2|1) sector and identify the set of states that corresponds to the SL(2)-like Bethe ansatz of Gromov and Vieira. Finally we extend part of our analysis to length-6 operators.

Waves and Solitons in the Calogero Model - Revisited

description: The Calogero model bears, in the continuum limit, collective excitations in the form of density waves and solitary modulations of the density of particles. This sector of the spectrum of the model was investigated, mostly within the framework of collective field theory, by several authors, over the past fifteen years or so. In this work we shall concentrate on periodic solutions of the collective BPS-equation (also known as "finite amplitude density waves"), as well as on periodic solutions of the full static variational equations which vanish periodically (also known as "large amplitude density waves"). While these solutions are not new, we feel that our analysis and presentation add to the existing literature, as we explain in the text. In addition, we show that these solutions also occur in a certain two-family generalization of the Calogero model, at special points in parameter space. A compendium of useful identities associated with Hilbert transforms, including our own proofs of these identities, appears in Appendix A. In Appendix B we also elucidate in the present paper some fine points having to do with manipulating Hilbert transforms, which appear ubiquitously in the collective field formalism. Finally, in order to make this paper self-contained, we briefly summarize in Appendix C basic facts about the collective field formulation of the Calogero model.

Using Symmetric State Transformations for Multi-Target Tracking
Creators: name: Baum, Marcus
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2011

description: This paper is about the use of symmetric state transformations for multi-target tracking. First, a novel method for obtaining point estimates for multi-target states is proposed. The basic idea is to apply a symmetric state transformation to the original state in order to compute a minimum mean-square-error (MMSE) estimate in a transformed state. By this means, the known shortcomings of MMSE estimates for multi-target states can be avoided. Second, a new multi-target tracking method based on state transformations is suggested, which entirely performs the time and measurement update in a transformed space and thus, avoids the explicit calculation of data association hypotheses and removes the target identity from the estimation problem. The performance of the new approach is evaluated by means of tracking two crossing targets.

description: Konferenz- und Tagungsberichte sind eine wichtige Informationsquelle, die den aktuellen Stand der Forschung dokumentieren. Zusätzlich zu gedruckten (oder elektronischen) Konferenzbänden werden mittlerweile auch immer häufiger Konferenzvorträge aufgezeichnet und diese Videos im Anschluss veröffentlicht. In den meisten Fällen werden diese Videos entweder auf kommerziellen Plattformen wie YouTube oder Vimeo, auf der Konferenz-Webseite oder gar nicht veröffentlicht.Während Bibliotheken über etablierte Verfahren zur Sammlung von Konferenzberichten im Rahmen der Erwerbung grauer Literatur verfügen, sind vergleichbare Verfahren für audiovisuelle Konferenzaufnahmen noch nicht etabliert. Demgegenüber ist laut Meeting und EventBarometer 2016 mehr als die Hälfte der Veranstalter und Organisatoren der Meinung, dass es Handlungsbedarf beim Aufbau virtueller Plattformen gibt, die das reale Geschehen ergänzen.Vor diesem Hintergrund hat die TIB eine Analyse der Bedürfnisse und Anforderungen von Konferenzorganisatoren und -veranstaltern sowie Dienstleistern im Bereich der audiovisuellen Aufzeichnung durchgeführt. Unter 30 Befragten wurden qualitative Interviews geführt, um herauszufinden, wie weit verbreitet Konferenzaufzeichnungen in den Ingenieur- und Naturwissenschaften sind.In diesem Beitrag präsentieren wir die Ergebnisse dieser Interview S. Fast die Hälfte (47%) der Befragten gab an, dass sie bereits Konferenzaufzeichnungen produziert haben (40 %) oder dies in Zukunft (7 %) planen. Die am häufigsten verwendeten Publikationsplattformen sind die eigene Konferenz-Website (92%) und YouTube (46%). Die Ergebnisse zeigen, dass ein großer Bedarf an nachhaltigen Publikationsplattformen, die den dauerhaften Zugang zu Konferenzaufzeichnungen gewährleisten, besteht. Die Studie wird ferner zur Verbesserung der Arbeitsabläufe und Dienstleistungen des TIB AV-Portals (https://av.tib.eu/) genutzt.
Bound state of 4$f$-excitation and magnetic resonance in unconventional superconductors

description: We analyze the influence of unconventional superconductivity on crystalline electric field (CEF) excitations of rare earth ions in novel superconductors. We show that resonant magnetic excitations of the conduction electrons that have been observed in these systems below T$_c$ may result in the formation of the bound state in the 4$f$-electron susceptibility. This occurs at energies well below the CEF excitation energy. The effect is discussed as a function of temperature and the strength of the coupling between the 4$f$ and $d$-electrons. We argue that these effects may be present in the layered cuprates and ferropnictides which contain rare-earth ions.

description: Expression patterns of CiWRKYs under ABA treatment. Samples were collected from the shoots of one-month-old C. intermedia seedlings at 0.5, 1, 3, 6, 12, 24 or 48 h following ABA treatment, and untreated plants were employed as the control. The expression levels of 28 CiWRKYs with full-length sequences were examined via qRT-PCR. Expression values were estimated using the 2-ΔΔCT method, and CiEF1α was used as reference gene. The error bars represent the means of three technical replicates ± SD. (PDF 254 kb)
Inelastic neutron scattering to isomeric levels
Creators: name: Truant, Paul Thomas
Publisher: name: University of British Columbia
Year: 2011

description: In order to use inelastic neutron scattering to isomeric levels as a tool in evaluating nuclear strength functions, we derive the appropriate evaporation formulae; both with and without corrections for the statistical fluctuations of the compound nucleus reduced partial widths. The isomeric activity induced by inelastic neutron scattering is calculated for: In¹¹⁵, Rh¹º³, Y⁸⁹ and Nb⁹³; and is used to illustrate the effect of the fluctuation corrections and the level spin and parity assignments, on the calculated cross sections. Comparison with experimental data is used to infer probable assignments of level spins and parities for In¹¹⁵ and Rh¹º³. We also show that for any nucleus lying near an even or odd partial wave strength function resonance, the inelastic neutron scattering cross section to isomeric levels will be directly proportional to l ≥ 2 strength functions. In the examples cited above, it is the d-wave strength function; and the isomeric cross section shows the corresponding dependence on the optical model potential, being directly proportional to the strength of the imaginary part and insensitive to the real part of the potential.

On epsilon_K beyond lowest order in the Operator Product Expansion

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We analyse the structure of long distance (LD) contributions to the CP-violating parameter epsilon_K, that generally affect both the absorptive (Gamma_12) and the dispersive (M_12) parts of the K0 -- K0bar mixing amplitude. We point out that, in a consistent framework, in addition to LD contributions to Im(Gamma_12), estimated recently by two of us, also LD contributions to Im(M_12) have to be taken into account. Estimating the latter contributions the impact of LD effects on epsilon_K is significantly reduced (from -6.0 % to -3.6 %). The overall effect of LD corrections and of the superweak phase being different from 45 degrees is summarised by the multiplicative factor kappa_epsilon = 0.94 +/- 0.02.

Optimal Gaussian Filtering for Polynomial Systems Applied to Association-free Multi-Target Tracking

name: Itte, Dominik

Publisher: name: Karlsruhe

description: This paper is about tracking multiple targets with the so-called Symmetric Measurement Equation (SME) filter. The SME filter uses symmetric functions, e.g., symmetric polynomials, in order to remove the data association uncertainty from the measurement equation. By this means, the data association problem is converted to a nonlinear state estimation problem. In this work, an efficient optimal Gaussian filter based on analytic moment calculation for discrete-time multi-dimensional polynomial systems corrupted with Gaussian noise is derived, and then applied to the polynomial system resulting from the SME filter. The performance of the new method is compared to an UKF implementation by means of typical multiple target tracking scenarios.
