description: The parabolic structure of the secondary or conjugate spectra of pulsars is often the result of isolated one-dimensional (or at least highly anisotropic) lenses in the ISM. The curvature of these features contains information about the velocities of the Earth, ISM, and pulsar along the primary axis of the lens. As a result, measuring variations in the curvature over the course of a year, or the orbital period for pulsars in binaries, can constrain properties of the screen and pulsar. In particular the pulsar distance and orbital inclination for binary systems can be found for multiple screens or systems with prior information on $\sin(i)$. By mapping the conjugate spectra into a space where the main arc and inverted arclets are straight lines, we are able to make use of the full information content from the inverted arclet curvatures, amplitudes, and phases using eigenvectors to uniquely and optimally retrieve phase information. This allows for a higher precision measurement than the standard Hough transform for systems where these features are available. Our technique also directly yields the best fit 1D impulse response function for the interstellar lens given in terms of the Doppler shift, time delay, and magnification of images on the sky as seen from a single observatory. This can be extended for use in holographic imaging of the lens by combining multiple telescopes. We present examples of this new method for both simulated data and actual observations of PSR B0834+06.

description: We present a general method to efficiently design optimal control sequences for non-Markovian open quantum systems, and illustrate it by optimizing the shape of a laser pulse to prepare a quantum dot in a specific state. The optimization of control procedures for quantum systems with strong coupling to structured environments -- where time-local descriptions fail -- is a computationally challenging task. We modify the numerically exact time evolving matrix product operator (TEMPO) method, such that it allows the repeated computation of the time evolution of the reduced system density matrix for various sets of control parameters at very low computational cost. This method is potentially useful for studying numerous optimal control problems, in particular in solid state quantum devices where the coupling to vibrational modes is typically strong.

description: NGC 5548 is the best-observed reverberation-mapped active galactic nucleus with long-term, intensive monitoring. Here we report results from a new observational campaign between January and July, 2015. We measure the centroid time lag of the broad H$β$ emission line with respect to the 5100 Åcontinuum and obtain $τ_{\rm cent} = 7.20^{+1.33}_{-0.35}$ days in the rest frame. This yields a black hole mass of $M_{\bullet}=8.71^{+3.21}_{-2.61} $x$ 10^{7}M_{\odot}$ using a broad H$β$ line dispersion of $3124\pm302$ km s$^{-1}$ and a virial factor of $f_{_{\rm BLR}}=6.3\pm1.5$ for the broad-line region (BLR), consistent with the mass measurements from previous H$β$ campaigns. The high-quality data allow us to construct a velocity-binned delay map for the broad H$β$ line, which shows a symmetric response pattern around the line center, a plausible kinematic signature of virialized motion of the BLR. Combining all the available measurements of H$β$ time lags and the associated mean 5100 Å luminosities over 18 campaigns between 1989 and 2015, we find that the H$β$ BLR size varies with the mean optical luminosity, but, interestingly, with a possible delay of $2.35_{-1.25}^{+3.47}$ yrs. This delay coincides with the typical BLR dynamical timescale of NGC 5548, indicating that the BLR undergoes dynamical changes, possibly driven by radiation pressure.

Comparison of the Pulkovo Compilation of Radial Velocities with the RAVE DR1 Catalogue

description: The Data Release 1 of the Radial-Velocity Experiment (RAVE DR1, 24 748 stars) is compared with the May 15, 2006 version of the Pulkovo Compilation of Radial Velocities (PCRV, 35 495 stars). RAVE DR1 includes mostly $9^m-13^m$ stars, while the PCRV contains brighter stars. Analysis of the "RAVE minus PCRV" radial-velocity differences for 14 common stars has revealed no systematic dependences on any factors, except the effect due to the RAVE radial-velocity zero-point offset known from the RAVE observations. This effect shows up for ten of these stars observed on a single night as a sine wave with an amplitude of 1.5 km s$^{-1}$ in the dependence of the radial-velocity difference on the ordinal number of the optical fiber used and, accordingly, on the star position angle in the field of view of the RAVE instrument. The detection of this dependence confirms a high radial-velocity accuracy in both catalogs: on average, better than 1 km s$^{-1}$ for stars brighter than $10^m$ (for the RAVE, after applying a correction for the zeropoint offset). The RAVE zero-point offset can be corrected for with an accuracy better than 1 km s$^{-1}$ by observing several PCRV stars in each RAVE frame and by analyzing the "RAVE minus PCRV" radialvelocity differences.

description: We consider the canonical ensemble of $N$-vertex Erdős-Rényi (ER) random topological graphs with quenched vertex degree, and with fugacity $μ$ for each closed triple of bonds. We claim complete defragmentation of large-$N$ graphs into the collection of $[p^{-1}]$ almost full subgraphs (cliques) above critical fugacity, $μ_c$, where $p$ is the ER bond formation probability. Evolution of the spectral density, $ρ(λ)$, of the adjacency matrix with increasing $μ$ leads to the formation of two-zonal support for $μ>μ_c$. Eigenvalue tunneling from one (central) zone to the other means formation of a new clique in the defragmentation process. The adjacency matrix of the ground state of a network has the block-diagonal form where number of vertices in blocks fluctuate around the mean value $Np$. The spectral density of the whole network in this regime has triangular shape. We interpret the phenomena from the viewpoint of the conventional random matrix model and speculate about possible physical applications.

description: We apply high-energy proton ion-implantation to modify TiO2 nanotubes selectively at their tops. In the proton-implanted region we observe the creation of intrinsic co-catalytic centers for photocatalytic H2-evolution. We find proton implantation to induce specific defects and a characteristic modification of the electronic properties not only in nanotubes but also on anatase single crystal (001) surfaces. Nevertheless, for TiO2 nanotubes a strong synergetic effect between implanted region (catalyst) and implant-free tube segment (absorber) can be obtained.

description: With the chiral susceptibility criterion we obtain the phase diagram of strong-interaction matter in terms of temperature and chemical potential in the framework of Dyson-Schwinger equations (DSEs) of QCD.After calculating the pressure and some other thermodynamic properties of the matter in the DSE method, we get the phase diagram in terms of temperature and baryon number density. We also obtain the interface tension and the interface entropy density to describe the inhomogeneity of the two phases in the coexistence region of the first order phase transition. After including the interface effect, we find that the total entropy density of the system increases in both the deconfinement (dynamical chiral symmetry restoration) and the hadronization (dynamical chiral symmetry breaking) processes of the first order phase transitions and thus solve the entropy puzzle in the hadronization process.

description: Nested sampling (NS) computes parameter posterior distributions and makes Bayesian model comparison computationally feasible. Its strengths are the unsupervised navigation of complex, potentially multi-modal posteriors until a well-defined termination point. A systematic literature review of nested sampling algorithms and variants is presented. We focus on complete algorithms, including solutions to likelihood-restricted prior sampling, parallelisation, termination and diagnostics. The relation between number of live points, dimensionality and computational cost is studied for two complete algorithms. A new formulation of NS is presented, which casts the parameter space exploration as a search on a tree data structure. Previously published ways of obtaining robust error estimates and dynamic variations of the number of live points are presented as special cases of this formulation. A new online diagnostic test is presented based on previous insertion rank order work. The survey of nested sampling methods concludes with outlooks for future research.

On the role of thermal boundary conditions in dynamo scaling laws
Creators: name: Oruba, Ludivine
Publisher: name: arXiv
Year: 2016
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: In dynamo power-based scaling laws, the power $P$ injected by buoyancy forces is measured by a so-called flux-based Rayleigh number, denoted as ${\rm Ra}_Q^*$ (see Christensen and Aubert, 2006). Whereas it is widely accepted that this parameter is measured (as opposite to controlled) in dynamos driven by differential heating, the literature is much less clear concerning its nature in the case of imposed heat flux. We clarify this issue by highlighting that in that case, the ${\rm Ra}_{Q}^*$ parameter becomes controlled only in the limit of large Nusselt numbers (${\rm Nu} \gg 1$). We then address the issue of the robustness of the original relation between $P$ and ${\rm Ra}_Q^*$ with the geometry and the thermal boundary conditions. We show that in the cartesian geometry, as in the spherical geometry with a central mass distribution, this relation is purely linear, in both differential and fixed-flux heating. However, we show that in the geometry commonly studied by geophysicists (spherical with uniform mass distribution), its validity places an upper-bound on the strength of the driving which can be envisaged in a fixed Ekman number simulation. An increase of the Rayleigh number indeed yields deviations (in terms of absolute correction) from the linear relation between $P$ and ${\rm Ra}_Q^*$. We conclude that in such configurations, the parameter range for which $P$ is controlled is limited.

description: We provide two closed-form geodesic formulas for a family of metrics on Stiefel manifold, parameterized by two positive numbers, having both the embedded and canonical metrics as special cases. The closed-form formulas allow us to compute geodesics by matrix exponential in reduced dimension for low-rank manifolds. Combining with the use of Fr{é}chet derivatives to compute the gradient of the square Frobenius distance between a geodesic ending point to a given point on the manifold, we show the logarithm map and geodesic distance between two endpoints on the manifold could be computed by {\it minimizing} this square distance by a {\it trust-region} solver. This leads to a new framework to compute the geodesic distance for manifolds with known geodesic formula but no closed-form logarithm map. We show the approach works well for Stiefel as well as flag manifolds. The logarithm map could be used to compute the Riemannian center of mass for these manifolds equipped with the above metrics. We also deduce simple trigonometric formulas for the Riemannian exponential and logarithm maps on the Grassmann manifold.

description: Gaia is a space mission currently measuring the five astrometric parameters as well as spectrophotometry of at least 1 billion stars to G = 20.7 mag with unprecedented precision. The sixth parameter in phase space (radial velocity) is also measured thanks to medium-resolution spectroscopy being obtained for the 150 million brightest stars. During the commissioning phase, two fields, one around each ecliptic pole, have been repeatedly observed to assess and to improve the overall satellite performances as well as the associated reduction and analysis software. A ground-based photometric and spectroscopic survey was therefore initiated in 2007, and is still running in order to gather as much information as possible about the stars in these fields. This work is of particular interest to the validation of the Radial Velocity Spectrometer (RVS) outputs. The paper presents the radial velocity measurements performed for the Southern targets in the 12 - 17 R magnitude range on high- to mid-resolution spectra obtained with the GIRAFFE and UVES spectrographs.

“Use the Force!” Adaptation of Response Formats

description: The present paper features the adaptation of an existing Big Five questionnaire with a rating scale (RS) response format into a measure using a multidimensional forced choice (MFC) response format. Rating scale response formats have been criticized for their proneness to intentional and unintentional response distortions. Multidimensional forced choice response formats were suggested as a solution to mitigate several types of response sets and response styles by design. The Big Five Inventory of Personality in Occupational Situations (B5PS) is a situation-based questionnaire designed for personnel selection and development purposes which would benefit from fake-proof response formats. MFC response formats require special effort during test construction and calibration which will be laid out here. Changing the response format has severe consequences on item design and scoring. An inherent issue with MFC formats derives from their inability to yield interpersonal comparative results from standard (sum) scoring. This issue can be solved with item response theory (IRT)-based calibration during test construction. The Thurstonian IRT approach (TIRT) was developed by Brown and Maydeu-Olivares (2011), and aspects of MFC item design and TIRT calibrations are explored in this paper. Evidence on structural and construct validity are presented alongside recommendations on the test development processes. The results support the feasibility of the concept of MFC test construction with TIRT calibration in a contextualized and situation-based item format.

description: Changes in the technological basis of public administration have a significant impact on socio-economic processes, implemented at different levels – from regional to international. Municipal-regional interaction in the field of digital tools implementation and use for the public administration implementation is of high importance. However, this process is highly informalized, first of all, regarding the stage of these tools implementation in pilot and production operation. This factor determines the relevance of determining the most significant aspects of the process of digital tools implementation in public administration, as a necessary component of its formalization and transition to using the quantitative calculation of the effectiveness of measures for digitalization of public administration. The purpose of this study is to analyze the processes of preparation for the operation of digital tools of municipal organizations in the context of municipal-regional interaction.

description: We have performed angle-resolved photoemission spectroscopy on HfSiS, which has been predicted to be a topological line-node semimetal with square Si lattice. We found a quasi-two-dimensional Fermi surface hosting bulk nodal lines, alongside the surface states at the Brillouin-zone corner exhibiting a sizable Rashba splitting and band-mass renormalization due to many-body interactions. Most notably, we discovered an unexpected Dirac-like dispersion extending one-dimensionally in k space - the Dirac-node arc - near the bulk node at the zone diagonal. These novel Dirac states reside on the surface and could be related to hybridizations of bulk states, but currently we have no explanation for its origin. This discovery poses an intriguing challenge to the theoretical understanding of topological line-node semimetals.

description: We study ribbons of vanishing Gaussian curvature, i.e., flat ribbons, constructed along a curve in $\mathbb{R}^{3}$. In particular, we first investigate to which extent the ruled structure determines a flat ribbon: in other words, we ask whether for a given curve $γ$ and ruling angle (angle between the ruling line and the curve's tangent) there exists a well-defined flat ribbon. It turns out that the answer is positive only up to an initial condition, expressed by a choice of normal vector at a point. We then study the set of infinitely narrow flat ribbons along a fixed curve $γ$ in terms of energy. By extending a well-known formula for the bending energy of the rectifying developable, introduced in the literature by Sadowsky in 1930, we obtain an upper bound for the difference between the bending energies of two solutions of the initial value problem. We finally draw further conclusions under some additional assumptions on the ruling angle and the curve $γ$.

description: Double Field Theory (DFT) is a low-energy effective theory of a manifestly $O(D,D)$ invariant formulation of the closed string theory when toroidally compactified dimensions are present. The theory is based on a doubled spacetime structure and, in order to preserve the gauge symmetry provided by the invariance under generalized diffeomorphisms, a constraint has to be imposed on fields and gauge parameters. In this paper, we propose a DFT-inspired Supergravity by using a suitable {\em star product} that implements such constraint and the corresponding algebraic structure is explored. We get a consistent DFT in which also an orthogonality condition of momenta is necessary for having a closed gauge algebra. In constructing this theory, we start from the simplest case of doubling one spatial dimension where the action is uniquely determined, without ambiguities, by the gauge symmetry. Then, the extension to the generic $O(D, D)$ case is presented. The result is consistent with the closed string field theory.

description: The purpose of this article is the investigation of the global control properties of a coupled nonlinear dispersive system posed in the periodic domain $\mathbb{T}$, a system with the structure of a nonlinear Schrödinger equation and a nonlinear Korteweg-de Vries equation. Combining estimates derived from Bourgain spaces and using microlocal analysis we show that this system has global control properties. The main novelty of this work is twofold. One is that the global results for the nonlinear system are presented for the first time thanks to the propagation of singularities. The second one is that these propagation results are shown to a coupled dispersive system with two equations defined by differential operators with principal symbols of different orders.

description: We compute curvatures of a family of tractable metrics on Stiefel manifolds, introduced recently by H{ü}per, Markina and Silva Leite, which includes the well-known embedded and canonical metrics on Stiefel manifolds as special cases. The metrics could be identified with the Cheeger deformation metrics. We identify parameter values in the family to make a Stiefel manifold an Einstein manifold and show Stiefel manifolds always carry an Einstein metric. We analyze the sectional curvature range and identify the parameter range where the manifold has non-negative sectional curvature. We provide the exact sectional curvature range when the number of columns in a Stiefel matrix is $2$, and a conjectural range for other cases. We derive the formulas from two approaches, one from a global curvature formula derived in our recent work, another using curvature formulas for left-invariant metrics. The second approach leads to curvature formulas for Cheeger deformation metrics on normal homogeneous spaces.

description: In this manuscript we define the right fractional derivative and its corresponding right fractional integral with exponential kernel. Then, we provide the integration by parts formula and we use $Q-$operator to confirm our results. The related Euler-Lagrange equations were obtained and one example is analyzed.

description: We use high accuracy photometric data obtained with the Kepler satellite to monitor the activity modulations of the Kepler-210 planet host star over a time span of more than four years. Following the phenomenology of the star's light curve in combination with a five spot model, we identify six different so-called spot seasons. A characteristic, which is common in the majority of the seasons, is the persistent appearance of spots in a specific range of longitudes on the stellar surface. The most prominent period of the observed activity modulations is different for each season and appears to evolve following a specific pattern, resembling the changes in the sunspot periods during the solar magnetic cycle. Under the hypothesis that the star exhibits solar-like differential rotation, we suggest differential rotation values of Kepler-210 that are similar to or smaller than that of the Sun. Finally, we estimate spot life times between 60 days and 90 days, taking into consideration the evolution of the total covered stellar surface computed from our model.

description: На сегодняшний день развитие экономики страны не может осуществляться без инновационной составляющей. Вследствие этого, последнее десятилетие РФ находится в процессе активного перехода к инновационной модели экономики. Интенсивная работа в этом направлении проводится в особенности на мезоуровне, но стоит отметить существенное отставание по уровню инновационного развития одних регионов от других. Центральный федеральный округ представляет собой один из наиболее высокоэффективных регионов в рамках формирования, развития и внедрения инноваций. Следовательно, регионы, входящие в состав данного округа, имеют высокий уровень инновационной привлекательности. Одним из самых важных факторов, влияющих на формирование инновационной привлекательности региона, является развитие организационно-экономического механизма инновационной инфраструктуры.
Stability of weak disorder phase for directed polymer with applications to limit theorems

Publisher: name: arXiv

Subjects: subject: Probability (math.PR)

subject: 60K37

description: We study the directed polymer model in a bounded environment with bond disorder and show that, in the interior of the weak disorder phase, weak disorder continues to hold upon perturbation by a small bias. Using this stability result, we give a new proof for the central limit theorem (CLT) in probability for the directed polymer model in the interior of the weak disorder phase. We also show that the large deviation rate function agrees with that of the underlying random walk. For the Brownian polymer model, we improve the convergence in the CLT to almost sure convergence in the whole weak disorder phase. The main technical tools are a new moment bound from \cite{J21_1} and a quantitative comparison between the associated martingales at different inverse temperatures.

Superrigidity for dense subgroups of Lie groups and their actions on homogeneous spaces

description: An essentially free group action of $Γ$ on $(X,μ)$ is called W*-superrigid if the crossed product von Neumann algebra $L^\infty(X) \rtimes Γ$ completely remembers the group $Γ$ and its action on $(X,μ)$. We prove W*-superrigidity for a class of infinite measure preserving actions, in particular for natural dense subgroups of isometries of the hyperbolic plane. The main tool is a new cocycle superrigidity theorem for dense subgroups of Lie groups acting by translation. We also provide numerous countable type $II_1$ equivalence relations that cannot be implemented by an essentially free action of a group, both of geometric nature and through a wreath product construction.

Michelson interferometer for measuring temperature

description: We investigate that temperature can be measured by a modified Michelson interferometer, where at least one reflected mirror is replaced by a thermalized sample. Both of two mirrors replaced by the corresponding two thermalized samples can help to approximatively improve the resolution of temperature up to twice than only one mirror replaced by a thermalized sample. For further improving the precision, a nonlinear medium can be employed. The Michelson interferometer is embedded in a gas displaying Kerr nonlinearity. We obtain the analytical equations and numerically calculate the precision with parameters within the reach of current technology, proving that the precision of temperature can be greatly enhanced by using a nonlinear medium. Our results show that one can create an accurate thermometer by measuring the photons in the Michelson interferometer, with no need for directly measuring the population of thermalized sample.

Cultural and creative sector representation for better policymaking

Subjects: CCS, production networks, policy networks, cultural and creative sector, EU-level representation

description: The GPN approach challenges conventional industry-based perspectives and reveals the fluid and dynamic nature of boundaries and relationships within the cultural and creative sectors (CCS). The CICERONE methodology, which incorporates linkages, flows, and networks, provides new insights for effective policymaking by uncovering meaningful connections between industries, sites, and local impacts. This raises the question of whether these flows and relationships are reflected in the influence of CCS stakeholders on policymaking. The analysis focuses on the policy ecosystem at the EU level, examining policy networks as determinants of policy outcomes and exploring the representation of interests within these networks. It highlights the fragmented engagement with CCS and the need for a coherent policy framework to address the sector's specificities and common needs. This deliverable emphasizes the importance of CCS representation in policymaking and explores two major EU policy initiatives: the establishment of a Knowledge Innovation Community (KIC) for culture and creativity and the implementation of the Resilience and Recovery Facility (RRF) in response to the COVID-19 pandemic. The examination of partners involved in the KIC project reveals the challenge of mobilizing CCS beyond sectoral policies, with limited representation from the industrial side of the sector. Similarly, the RRF, despite being identified as a priority for CCS, missed the opportunity for cohesive action and joint influence on EU and national strategies. The section concludes by highlighting the need for a more comprehensive and cohesive approach to CCS representation in policymaking processes. Overall, the deliverable underscores the need to reconsider CCS representation and its organization to ensure a more inclusive and impactful participation in policymaking. The fragmented engagement and lack of representation hinder a holistic understanding of CCS's contribution to various policy objectives and limit the sector's ability to address policy gaps effectively. By advocating for a coherent policy framework and collaborative action, the section emphasizes the importance of empowering CCS stakeholders and creating a platform for their meaningful involvement in shaping policies at the EU and national levels.
On the semisimplicity of the category $KL_k$ for affine Lie superalgebras

description: We study the semisimplicity of the category $KL_k$ for affine Lie superalgebras and provide a super analog of certain results from arXiv:1801.09880. Let $KL_k^{fin}$ be the subcategory of $KL_k$ consisting of ordinary modules on which the Cartan subalgebra acts semisimply. We prove that $KL_k^{fin}$ is semisimple when 1) $k$ is a collapsing level, 2) $W_k(\mathfrak{g}, θ)$ is rational, 3) $W_k(\mathfrak{g}, θ)$ is semisimple in a certain category. The analysis of the semisimplicity of $KL_k$ is subtler than in the Lie algebra case, since in super case $KL_k$ can contain indecomposable modules. We are able to prove that in many cases when $KL_k^{fin}$ is semisimple we indeed have $KL_k^{fin}=KL_k$, which therefore excludes indecomposable and logarithmic modules in $KL_k$. In these cases we are able to prove that there is a conformal embedding $W \hookrightarrow V_k(\mathfrak{g})$ with $W$ semisimple (see Section 10). In particular, we prove the semisimplicity of $KL_k$ for $\mathfrak{g}=sl(2\vert 1)$ and $k = -\frac{m+1}{m+2}$, $m \in {\mathbb Z}_{\ge 0}$. For $\mathfrak{g} =sl(m \vert 1)$, we prove that $KL_k$ is semisimple for $k=-1$, but for $k=1$ we show that it is not semisimple by constructing indecomposable highest weight modules in $KL_k^{fin}$.
