description: Sedimentologic, pedologic and geochemical data are integrated to interpret the Gilwood Mbr delta system in Nipisi field and its stratigraphic outcrop correlative, the Yahatinda Fm. Five papers are presented with an emphasis on the mudstones and carbonates comprising interfluve paleosols, lacustrine, shallow marine and peritidal deposits. Because paleosols are laterally extensive and mark significant time periods of subaerial exposure, they are useful for correlations, paleogeographic reconstructions and sequence stratigraphic analysis. Proving that these buried paleosols can be used for correlation purposed necessitates determining the conditions and time periods during which they formed. For the Gilwood Mbr this required using relative degradation of organic matter to determine maturity as standard geochemical methods showed paleosols as relatively homogeneous. Enigmatic dolocrete and calcrete within mudstone and sandstone host rock were interpreted as due to the interaction of pedogenic, vadose and phreatic processes. Lateral distribution of carbonates reflect paleogroundwater tables and show that groundwater flow was centripetal, into a fault controlled low within Nipisi field. The faulting associated with this low was related to resurgent tectonism of the Peace River Arch, which was a sediment source and possibly dissolution of salt in the underlying strata. This central low contained an ephemeral lake and created accommodation space for thicker sediments prior to and during Gilwood Mbr deposition. Tectonism, sediment supply and accommodation space within a transgressive systems tract are reflected by four progradational-aggradational parasequence sets overlain by a retrogradational parasequence. Each parasequence is comprised of a coarsening upward sandstone succession overlain by marine mudstones and paleosols. The delta system had a: (1) low slope delta plain, with shallow ephemeral, sandy braided channels; (2) dissipative, shoreline zone; and (3) delta front dominated by hyperpycnal flows. Correlation of paleosol chronosequences within the peritidal deposits of the Yahatinda Fm support its correlation to Gilwood Mbr deposits to the north. Deposition within a transgressive systems tract is supported by the observed sedimentology, however it is dissimilar to predicted idealized models of paleosol chronosequences.

description: We examine how to distinguish between unitary operators, when the exact form of the possible operators is not known. Instead we are supplied with "programs" in the form of unitary transforms, which can be used as references for identifying the unknown unitary transform. All unitary transforms should be used as few times as possible. This situation is analoguous to programmable state discrimination. One difference, however, is that the quantum state to which we apply the unitary transforms may be entangled, leading to a richer variety of possible strategies. By suitable selection of an input state and generalized measurement of the output state, both unambiguous and minimum-error discrimination can be achieved. Pairwise comparison of operators, comparing each transform to be identified with a program transform, is often a useful strategy. There are, however, situations in which more complicated strategies perform better. This is the case especially when the number of allowed applications of program operations is different from the number of the transforms to be identified.

description: The availability of electromagnetic pulses with controllable field waveform and extremely short duration, even below a single optical cycle, is imperative to fully harness strong-field processes and to gain insight into ultrafast light-driven mechanisms occurring in the attosecond time-domain. The recently demonstrated parametric waveform synthesis (PWS) introduces an energy-, power- and spectrum-scalable method to generate non-sinusoidal sub-cycle optical waveforms by coherently combining different phase-stable pulses attained via optical parametric amplifiers. Significant technological developments have been addressed to overcome the stability issues related to PWS and to obtain an effective and reliable waveform control system. Here we present the main ingredients enabling PWS technology. The design choices concerning the optical, mechanical and electronic setups are justified by analytical/numerical modeling and benchmarked by experimental observations. In its present incarnation, the PWS technology enables the generation of field-controllable mJ-level few-femtosecond pulses spanning the visible to infrared range.

description: We investigate the effect of a specific edge weighting scheme $\sim (k_i k_j)^β$ on distributed flow efficiency and robustness to cascading failures in scale-free networks. In particular, we analyze a simple, yet fundamental distributed flow model: current flow in random resistor networks. By the tuning of control parameter $β$ and by considering two general cases of relative node processing capabilities as well as the effect of bandwidth, we show the dependence of transport efficiency upon the correlations between the topology and weights. By studying the severity of cascades for different control parameter $β$, we find that network resilience to cascading overloads and network throughput is optimal for the same value of $β$ over the range of node capacities and available bandwidth.

description: We investigate the extent to which perturbative calculations of the electroweak phase transition are arbitrary and uncertain, owing to their gauge, renormalisation scale and scheme dependence, as well as treatments of the Goldstone catastrophe and daisy diagrams. Using the complete parameter space of the Standard Model extended by a real scalar singlet with a $\mathbb{Z}_2$ symmetry as a test, we explore the properties of the electroweak phase transition in general $R_ξ$ and covariant gauges, OS and $\overline{\text{MS}}$ renormalisation schemes, and for common treatments of the Goldstone catastrophe and daisy diagrams. Reassuringly, we find that different renormalisation schemes and different treatments of the Goldstone catastrophe and daisy diagrams typically lead to only modest changes in predictions for the critical temperature and strength of the phase transition. On the other hand, the gauge and renormalisation scale dependence may be significant, and often impact the existence of the phase transition altogether.

description: The battery passport is proposed as a method to make the use and remaining value of batteries more transparent. The future EU Battery Directive requests this passport to contain the round-trip energy efficiency and its fade. In this paper, an algorithm is presented and demonstrated that estimates the round-trip energy efficiency of a battery pack. The algorithm identifies round trips based on battery current and SoC and characterizes these round trips based on certain conditions. 2D efficiency maps are created as a function of the conditions `temperature' and `RMS C-rate'. The maps are parameterized using multiple linear regression, which allows comparison of the efficiency under the same conditions. Analyzing data from three battery-electric buses over a period of 3.5 years reveals an efficiency fade of up to 0.86 percent point.

description: SWELTO - Space WEather Laboratory in Turin Observatory is a conceptual framework where new ideas for the analysis of space-based and ground-based data are developed and tested. The input data are (but not limited to) remote sensing observations (EUV images of the solar disk, Visible Light coronagraphic images, radio dynamic spectra, etc...), in situ plasma measurements (interplanetary plasma density, velocity, magnetic field, etc...), as well as measurements acquired by local sensors and detectors (radio antenna, fluxgate magnetometer, full-sky cameras, located in OATo). The output products are automatic identification, tracking, and monitoring of solar stationary and dynamic features near the Sun (coronal holes, active regions, coronal mass ejections, etc...), and in the interplanetary medium (shocks, plasmoids, corotating interaction regions, etc...), as well as reconstructions of the interplanetary medium where solar disturbances may propagate from the Sun to the Earth and beyond. These are based both on empirical models and numerical MHD simulations. The aim of SWELTO is not only to test new data analysis methods for future application for Space Weather monitoring and prediction purposes, but also to procure, test and deploy new ground-based instrumentation to monitor the ionospheric and geomagnetic responses to solar activity. Moreover, people involved in SWELTO are active in outreach to disseminate the topics related with Space Weather to students and the general public.
Multivariate probabilistic forecasting using Bayesian model averaging and copulas

description: We propose a method for post-processing an ensemble of multivariate forecasts in order to obtain a joint predictive distribution of weather. Our method utilizes existing univariate post-processing techniques, in this case ensemble Bayesian model averaging (BMA), to obtain estimated marginal distributions. However, implementing these methods individually offers no information regarding the joint distribution. To correct this, we propose the use of a Gaussian copula, which offers a simple procedure for recovering the dependence that is lost in the estimation of the ensemble BMA marginals. Our method is applied to 48-h forecasts of a set of five weather quantities using the 8-member University of Washington mesoscale ensemble. We show that our method recovers many well-understood dependencies between weather quantities and subsequently improves calibration and sharpness over both the raw ensemble and a method which does not incorporate joint distributional information.

On the role of laminar/turbulent interface on energy transfer between scales in bypass transition

Year: 2022
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We investigate the role of laminar/turbulent interface in the interscale energy transfer in a boundary layer undergoing bypass transition, with the aid of the Karman-Howarth-Monin-Hill (KHMH) equation. A local binary indicator function is used to detect the interface and employed subsequently to define two-point intermittencies. These are used to decompose the standard-averaged interscale and interspace energy fluxes into conditionally-averaged components. We find that the inverse cascade in the streamwise direction reported in an earlier work arises due to events across the downstream or upstream interfaces (head or tail respectively) of a turbulent spot. However, the three-dimensional energy flux maps reveal significant differences between these two regions: in the downstream interface, inverse cascade is stronger and dominant over a larger range of streamwise and spanwise separations. We explain this finding by considering a propagating spot of simplified shape as it crosses a fixed streamwise location. We derive also the conditionally-averaged KHMH equation, thus generalising similar equations for single-point statistics to two-point statistics. We compare the three-dimensional maps of the conditionally-averaged production and total energy flux within turbulent spots against the maps of standard-averaged quantities within the fully turbulent region. The results indicate remarkable dynamical similarities between turbulent spots and the fully turbulent region for two-point statistics. This has been known only for single-point quantities, and we show here that the similarity extends to two-point quantities as well.

description: Ao pensar sobre a Amazônia, o que permeia o imaginário de primeiro momento é a biodiversidade que a floresta possui nos seus mais de 5.500.000 km² de extensão. Entretanto, o lugar que é rico em projetos de minério, extrativismo vegetal, pesca e outros itens valiosos para o Brasil e o Mundo, também possui uma grande parcela da população em vulnerabilidade social e padece de políticas públicas eficientes para resguardar os direitos intrínsecos à dignidade humana. Assim, a Amazônia é apenas como um retrato, onde se pode extrair preciosidades, e, por vezes, a única questão vista na esfera global são as de cunho ecológico, sobretudo, que afligem interesses econômicos. Os problemas que atingem a comunidade são negligenciados, as vidas que existem nos locais mais isolados das grandes capitais são esquecidas.

description: openCost is a project funded by the German Research Foundation and was launched by the three project partners Bielefeld University Library, University Library Regensburg and DESY Central Library in 2022.The project's main goal is to promote standardized collecting of publication cost data in order to improve the transparency of costs within institutions and also enable inter-institutional cost comparisons. This kind of data includes publication-related fees like APCs or submission fees, but also costs from transformative OA agreements or memberships. The basic idea is to integrate this kind of financial data directly into repositories on record level, making it accessible together with the existing bibliographic metadata. For this purpose, a metadata schema was developed to comprehensively store and exchange the data. In the first part of our talk we present this XML schema and show how the partner institutions utilize it to enrich their repositories with publication cost data. Via OAI-PMH these publication expenses are currently harvested directly by OpenAPC, a service located at the Bielefeld University Library, which collects and disseminates data sets on fees paid for open access publishing under an open database license. The second part of the presentation introduces this harvesting process and presents first results.

This Milestone will, accordingly, outline the key points of both of these events and direct the reader to further information on each. A final section summarises the result of these activities, and describes how they will impact the development of the CDIF guidelines.

description: Pseudo-scalar inflation coupled with U(1) gauge fields through the Chern-Simons term has been extensively studied. However, new physics arising from UV theories may still influence the pseudo-scalar field at low-energy scales, potentially impacting predictions of inflation. In the realm of effective field theory (EFT), we investigated axion inflation, where operators from heavy fields are also present, in addition to the axion and gauge fields. The integrated out fields have two significant effects: the non-linear dispersion regime and coupling heavy modes to the Chern-Simons term. The first effect changes the propagation of the curvature fluctuation, while the second one results in additional operators that contribute to curvature fluctuation via inverse decay. We derived the power spectrum and magnitude of equilateral non-Gaussianity in this low-energy EFT. We found that the second effect could become significant as the mass of heavy fields approaches Hubble scale.

Template-based sketch recognition using Hidden Markov Models
Creators: name: Flor, Roey
Publisher: name: University of British Columbia
Year: 2010

description: Sketch recognition is the process by which the objects in a hand-drawn diagram can be recognized and identified. We provide a method to recognize objects in sketches by casting the problem in terms of searching for known 2D template shapes in the sketch. The template is defined as an ordered polyline and the recognition requires searching for a similarly-shaped sequential path through the line segments that comprise the sketch. The search for the best-matching path can be modeled using a Hidden Markov Model (HMM). We use an efficient dynamic programming method to evaluate the HMM with further optimizations based on the use of hand-drawn sketches. The technique we developed can cope with several issues that are common to sketches such as small gaps and branching. We allow for objects with either open or closed boundaries by allowing backtracking over the templates. We demonstrate the algorithm for a variety of templates and scanned drawings. We show that a likelihood score produced by the results can provide a meaningful measure of similarity to a template. An example-based method is presented for setting a meaningful recognition threshold, which can allow further refinement of results when that template is used again. Limitations of the algorithm and directions for future work are discussed.

description: We discuss quantum scale invariance in (scale invariant) gauge theories with both ultraviolet (UV) and infrared (IR) divergences. Firstly, their BRST invariance is checked in two apparently unrelated approaches using a scale invariant regularisation (SIR). These approaches are then shown to be equivalent. Secondly, for the Abelian case we discuss both UV and IR quantum corrections present in such theories. We present the Feynman rules in a form suitable for offshell Green functions calculations, together with their one-loop renormalisation. This information is then used for the muon production cross section at one-loop in a quantum scale invariant theory. Such a theory contains not only new UV poles but also IR poles. While the UV poles bring new quantum corrections (in the form of counterterms), finite or divergent, that we compute, it is shown that the IR poles do not bring new physics. The IR quantum corrections, both finite and divergent, cancel out similarly to the way the IR poles themselves cancel in the traditional approach to IR divergences (in the cross section, after summing over virtual and real corrections). Hence, the evanescent interactions induced by the scale-invariant analytical continuation of the SIR scheme do not affect IR physics, as illustrated at one-loop for the muon production ($e^+ e^- \to μ^+μ^-$) cross section.

description: We use a combination of density functional theory and Monte Carlo calculations to calculate the surface magnetization in magnetoelectric $\mathrm{Cr_2O_3}$ at finite temperatures. Such antiferromagnets, lacking both inversion and time-reversal symmetries, are required by symmetry to posses an uncompensated magnetization density on particular surface terminations. Here, we first show that the uppermost layer of magnetic moments on the $(001)$ surface remain paramagnetic at the bulk Néel temperature, bringing the theoretical estimate of surface magnetization density in line with experiment. We demonstrate that the lower surface ordering temperature compared to bulk is a generic feature of surface magnetization when the termination reduces the effective Heisenberg coupling. We then propose two methods by which the surface magnetization in $\mathrm{Cr_2O_3}$ could be stabilised at higher temperatures. Specifically, we show that the effective coupling of surface magnetic ions can be drastically increased either by a different choice of surface Miller plane, or by $\mathrm{Fe}$ doping. Our findings provide an improved understanding of surface magnetization properties in AFMs.

description: High-$T_c$ cuprate superconductors are characterized by a strong momentum-dependent anisotropy between the low energy excitations along the Brillouin zone diagonal (nodal direction) and those along the Brillouin zone face (antinodal direction). Most obvious is the d-wave superconducting gap, with the largest magnitude found in the antinodal direction and no gap in the nodal direction. Additionally, while antinodal quasiparticle excitations appear only below $T_c$, superconductivity is thought to be indifferent to nodal excitations as they are regarded robust and insensitive to $T_c$. Here we reveal an unexpected tie between nodal quasiparticles and superconductivity using high resolution time- and angle-resolved photoemission on optimally doped Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$. We observe a suppression of the nodal quasiparticle spectral weight following pump laser excitation and measure its recovery dynamics. This suppression is dramatically enhanced in the superconducting state. These results reduce the nodal-antinodal dichotomy and challenge the conventional view of nodal excitation neutrality in superconductivity.

description: Inclusive semileptonic $B\to X_c \ell \barν_\ell$ decays, where $\ell = μ,e$, are by now standard candles in the determination of the CKM element $|V_{cb}|$. These determinations rely on the heavy-quark expansion and use moments of decay spectra to extract the non-perturbative parameters directly from data under the standard model assumption. At the same time, new physics could influence the moments of the inclusive decay. In this paper, we compute power-corrections and next-to-leading order corrections in the strong coupling constant using the full basis of dimension-six new physics operators for the inclusive $B \to X_c \ell \barν$ decay. We provide predictions for lepton energy, hadronic and leptonic invariant mass moments, and perform a phenomenological study to show the possible impact of new physics. Our results could be used to perform a global fit including new physics contributions.

description: The GAIA digital board developed by INAF was designed to bias up to ten stages of cryogenic low noise amplifiers (LNAs) and to deliver a maximum drain current Idmax50 mA with a drain voltage Vdmax5 V for each of them. The GAIA board monitors and controls each of the stages independently. However, such board cannot be employed to monitor and control the AETHRA WP1 75-116 GHz downconverter module as the power amplifiers of the fully-integrated MMIC developed at IAF, integrated into the downconverter module, require current values of up to 300 mA each, that is six times greater than what GAIA can deliver. Therefore, a power stage of the GAIA board has to be developed to comply with the high-current bias requirements of the AETHRA WP1 downconverter. Here, we describe the design of the power stage of the GAIA board, named PSG (Power Stage Gaia). The PSG is a four-layer digital bias board, to be connected in series with GAIA, capable of delivering up to 10 × high-current stages. One GAIA board is used to monitor and control one PSG board. The latter is an extension of GAIA and cannot be used independently of it. Therefore, one GAIA board plus one PSG board must be used in conjunction to monitor and control up to 10 high-current stages of the AETHRA WP1 downconverter. The version 1.2 of the GAIA board, developed for biasing, monitoring and controlling of the LNAs, cannot be used in conjunction with the PSG but requires a small modification to allow data interchange between the two boards. A new GAIA board, version 1.5, must be used in conjunction with the PSG.

description: The combined cycle power plants are the most recognized thermal power plants for their high efficiency, fast start-up capability, and relatively low environmental impact. Moreover, their flexible unit dispatch supports the share of renewable energy, which contributes to carbon mitigation. The operational flexibility of Integrated Solar Combined Cycle (ISCC) power plants is a crucial factor for reliable grid stability. To evaluate the limitations and capabilities of ISCC power plants and their control structures, dynamic simulation is a feasible method. In this study, a sophisticated dynamic process model of the ISCC power plant in Kuraymat, Egypt, has been developed using APROS software. The model describes the plant with a high level of detail including the solar field, the heat recovery steam generator, and the control structures. The model was implemented structurally identical to the reference plant and tuned using the operational design data. Actual measurements were used as the basis for the initialization and validation of the dynamic simulation environment. Dynamic analysis of four different days was performed, then the simulation results were presented and compared with actual measurements. The comparison showed that the course of the actual measurements could be predicted with high accuracy. The solar field influences and the system’s overall power curves are reliably simulated. Consequently, the validated model can simulate the dynamic behavior of the ISCC power plant with a high degree of accuracy, and can be considered in future planning decisions.

description: Given a weighted $\ell^2$ space with weights associated to an entire function, we consider pairs of weighted shift operators, whose commutators are diagonal operators, when considered as operators over a general Fock space. We establish a calculus for the algebra of these commutators and apply it to the general case of Gelfond-Leontiev derivatives. This general class of operators includes many known examples, like classic fractional derivatives and Dunkl operators. This allows us to establish a general framework which goes beyond the classic Weyl-Heisenberg algebra. Concrete examples for its application are provided.
Evading the sign problem in random matrix simulations

description: In this talk we show how the sign problem, occurring in dynamical simulations of random matrices at nonzero chemical potential, can be avoided by judiciously combining matrices into subsets. One can prove that these subsets have real and positive weights such that importance sampling can be used in Monte Carlo simulations. The number of matrices per subset is proportional to the matrix dimension. We measure the chiral condensate and observe that the statistical error is independent of the chemical potential and grows linearly with the matrix dimension, which contrasts strongly with its exponential growth in reweighting methods.

description: The role of experts and their competencies in contemporary society are at the core of current debates in democratising technological cultures and establishing innovative forms of responsible dialogue within society. This section offers a reworking of the materials presented during the seminar hosted by “Giannino Bassetti” Foundation in Milan on May 3, 2010. The first article is part of the keynote speech given by Wiebe Bijker, one of the founding scholars of STS in the European scene. He draws from ethnographic results of his research on the Dutch Health Council and the risk governance of nanotechnologies. Two comments follow. The first one, by Paolo Volonté, focuses on the relationship between democracy and scientific knowledge, as well as the subtle ambivalence of democratisation starting from the intrinsic undemocratic character of scientific authority. The second comment by Cristina Grasseni emphasises the implications of a committed engagement of citizens in shaping forms of responsible innovation, when taking the science governance seriously.

description: In this paper, we present recent progress in the development of hydrophobic silica aerogel as a Cherenkov radiator. In addition to the conventional method, the recently developed pin-drying method for producing high-refractive-index aerogels with high transparency was studied in detail. Optical qualities and large tile handling for crack-free aerogels were investigated. Sufficient photons were detected from high-performance aerogels in a beam test.

description: Symmetry and symmetry breaking are two pillars of modern quantum physics. Still, quantifying how much a symmetry is broken is an issue that has received little attention. In extended quantum systems, this problem is intrinsically bound to the subsystem of interest. Hence, in this work, we borrow methods from the theory of entanglement in many-body quantum systems to introduce a subsystem measure of symmetry breaking that we dub entanglement asymmetry. As a prototypical illustration, we study the entanglement asymmetry in a quantum quench of a spin chain in which an initially broken global $U(1)$ symmetry is restored dynamically. We adapt the quasiparticle picture for entanglement evolution to the analytic determination of the entanglement asymmetry. We find, expectedly, that larger is the subsystem, slower is the restoration, but also the counterintuitive result that more the symmetry is initially broken, faster it is restored, a sort of quantum Mpemba effect, a phenomenon that we show to occur in a large variety of systems.

description: The charged and neutral pion photoproduction reactions are investigated in a dynamical coupled-channels approach based on the formulation of Haberzettl, Huang, and Nakayama [Phys. Rev. C 83, 065502 (2011)]. The hadronic final-state interaction is provided by the Juelich pi-N model, which includes the channels pi-N and eta-N comprising stable hadrons as well as the effective pi-pi-N channels pi-Delta, sigma-N, and rho-N. This hadronic model has been quite successful in describing pi-N to pi-N scattering for center-of-mass energies up to 1.9 GeV. By construction, the full pion photoproduction current satisfies the generalized Ward-Takahashi identity and thus is gauge invariant as a matter of course. The calculated differential cross sections and photon spin asymmetries up to 1.65 GeV center-of-mass energy for the reactions gamma p to pi+ n, gamma p to pi0 p, gamma n to pi- p and gamma n to pi0 n are in good agreement with the experimental data.
