description: Encoding classical data into quantum states is considered a quantum feature map to map classical data into a quantum Hilbert space. This feature map provides opportunities to incorporate quantum advantages into machine learning algorithms to be performed on near-term intermediate-scale quantum computers. The crucial idea is using the quantum Hilbert space as a quantum-enhanced feature space in machine learning models. While the quantum feature map has demonstrated its capability when combined with linear classification models in some specific applications, its expressive power from the theoretical perspective remains unknown. We prove that the machine learning models induced from the quantum-enhanced feature space are universal approximators of continuous functions under typical quantum feature maps. We also study the capability of quantum feature maps in the classification of disjoint regions. Our work enables an important theoretical analysis to ensure that machine learning algorithms based on quantum feature maps can handle a broad class of machine learning tasks. In light of this, one can design a quantum machine learning model with more powerful expressivity.

description: In this article, we prove that the measures $\mathbb{Q}_T$ associated to the one-dimensional Edwards' model on the interval $[0,T]$ converge to a limit measure $\mathbb{Q}$ when $T$ goes to infinity, in the following sense: for all $s\geq0$ and for all events $Λ_s$ depending on the canonical process only up to time $s$, $\mathbb{Q}_T(Λ_s)\rightarrow\mathbb{Q}(Λ_s)$. Moreover, we prove that, if $\mathbb{P}$ is Wiener measure, there exists a martingale $(D_s)_{s\in\mathbb{R}_+}$ such that $\mathbb{Q}(Λ_s) =\mathbb{E}_{\mathbb{P}}(\mathbh{1}_{Λ_s}D_s)$, and we give an explicit expression for this martingale.

description: Die ökologische Krise beschreibt die Umweltverschmutzung, die durch den Menschen verursacht wird. Der Klimawandel und der saure Regen stellen dabei lediglich zwei Folgen dieser Krise dar. Durch die Einbringung von Schadstoffen in die Umwelt wird das menschliche und tierische Leben gefährdet, lebende Ressourcen geschädigt und ökologische Schäden ausgelöst. Da der Mensch Verursacher der Umweltverschmutzung ist, kann diese nur durch einen Bewusstseinswandel verhindert werden. Direkte Begegnungen mit der Natur in der Kindheit können einen positiven Einfluss auf das Umwelthandeln von Erwachsenen haben und zu einem verantwortungsvollen Umgang mit der Umwelt anregen. Daher können Naturerfahrungen in der Schule einen wesentlichen Beitrag zur Entstehung umweltbewusster Einstellungen leisten und zu einer wirksamen Umweltbildung beitragen. Durch die Umweltbildung werden Einsichten in die komplexen Zusammenhänge des Umweltgefüges vermittelt, wodurch diese zur Ausbildung eines Umweltbewusstseins beiträgt. Für die Vermittlung umweltbewusster Einstellungen eignet sich die Flussperlmuschel (Margaritifera margaritifera) als Unterrichtsgegenstand, welche bereits als ausgestorben oder verschollen gilt. Der Grund ihres Gefährdungsstatus ist die ökologische Krise. Der im Zuge der Umweltverschmutzung entstehende saure Regen, verändert den Lebensraum der empfindlichen Flussperlmuschel und macht ihr Überleben unmöglich.

description: Recent theoretical analysis of spatially-nonuniform modes of the thermomagnetic instability in superconductors [Phys. Rev. B 70, 224502 (2004)] is generalized to the case of a thin film in a perpendicular applied field. We solve the thermal diffusion and Maxwell equations taking into account nonlocal electrodynamics in the film and its thermal coupling to the substrate. The instability is found to develop in a nonuniform, fingering pattern if the background electric field, E, is high and the heat transfer coefficient to the substrate, h0, is small. Otherwise, the instability develops in a uniform manner. We find the threshold magnetic field, H_fing(E,h0), the characteristic finger width, and the instability build-up time. Thin films are found to be much more unstable than bulk superconductors, and have a stronger tendency for formation of dendritic pattern.

description: We present the results of a monitoring campaign of the double quasar SBS1520+530 at Maidanak observatory from April 2003 to August 2004. We obtained light curves in V and R filters that show small-amplitude Δm~0.1 mag intrinsic variations of the quasar on time scales of about 100 days. The data set is consistent with the previously determined time delay of Δt=(130+-3) days by Burud et al. (2002). We find that the time delay corrected magnitude difference between the quasar images is now larger by (0.14+-0.03) mag than during the observations by Burud et al. (2002). This confirms the presence of gravitational microlensing variations in this system.

description: Recent works on medieval manuscripts often combine historic research on textual content and illuminated decoration with material studies, such as pigment characterization, but less frequently with the material structure of codices or their bookbinding features. Despite some scholars having addressed this subject, bookbinding studies continue to lag behind other book-related fields; thus comparisons between different works, to arrive at broader understandings, become a rather difficult task. In this article, a new digital tool to record and compare bookbinding features and materials within the medieval collection of codices produced in the Monastery of Alcobaça is presented. Our methodology is explained, from the compilation of a multilanguage glossary to the design of a digital table-based method for bookbinding descriptions, based on up-to-date international projects and bibliography. This tool addresses the main parts of the book structure (bookblock, sewing and endbands, supports, boards, covering, fastening, and furnishing elements), along with their material analysis. As a starting point, three selected codices serve to establish the criteria and to check the efficiency of the data recording process. Results from these case studies allow a preliminary evaluation of the advantages of the proposed innovative tool for medieval bookbinding studies.
Testing and evaluation of modifying reagents in potash flotation
Creators: name: Perucca, Carlos Francisco
Publisher: name: University of British Columbia
Year: 2009

description: Potash is the main source of Potassium which is one of the three basic plant nutrients along with nitrogen and phosphorus. Between 60 to 80% of the potash ore is processed by flotation, the other two important unit operations are hot or cold crystallization and electrostatic separation. Almost all the published literature on potash flotation refers to the insoluble minerals as "collector robbers" and increased collector usage is mentioned as the consequence of the presence of slimes in potash flotation circuits. The real effect of the presence of slimes in potash flotation is far more complex. The test program developed in the following chapters aimed to determine the most suitable modifying reagent(s) and the optimum dosage to optimize grade and recovery of KCI, and to evaluate various flocculants used in flotation desliming in order to determine the factors that affect flotation desliming efficiency. Based on the results, it can be stated that guar gum is probably the most effective insoluble slimes depressant for the ores under the conditions tested. The depressing action of the guar gum is strong even at low dosages (50 g/t). Carboxymethyl cellulose shows poor depressing ability at low dosages, with increasing depression performance at high dosages (200 g/t). Synthetic polyacrylamides can hardly be considered insoluble slimes "depressants" as a considerable amount of the insoluble slimes present in the feed report to the concentrate. Anionic flocculants increase insoluble slimes recovery when used instead of non-ionic flocculant at the same dosage. The recovery of KCI to the insolubles concentrate increases with the use of anionic flocculants as well but in a much smaller proportion. The flocculation-flotation of insoluble minerals is a flocculant dependent process, and the addition of a "insolubles collector" or a frother, or nothing at all merely affects the kinetics of the process.
Antiferromagnetism and hot spots in CeIn$_3$

description: Enormous mass enhancement at ''hot spots'' on the Fermi surface (FS) of CeIn$_3$ has been reported at strong magnetic field near its antiferromagnetic (AFM) quantum critical point [T. Ebihara et al., Phys. Rev. Lett. 93, 246401 (2004)] and ascribed to anomalous spin fluctuations at these spots. The ''hot spots'' lie at the positions on FS where in non-magnetic LaIn$_3$ the narrow necks are protruded. In paramagnetic phase CeIn$_3$ has similar spectrum. We show that in the presence of AFM ordering its FS undergoes a topological change at the onset of AFM order that truncates the necks at the ''hot spots'' for one of the branches. Applied field leads to the logarithmic divergence of the dHvA effective mass when the electron trajectory passes near or through the neck positions. This effect explains the observed dHvA mass enhancement at the ''hot spots'' and leads to interesting predictions concerning the spin-dependence of the effective electron mass. The (T,B)-phase diagram of CeIn$_3$, constructed in terms of the Landau functional, is in agreement with experiment.

description: Spin-weighted spheroidal harmonics are useful in a variety of physical situations, including light scattering, nuclear modeling, signal processing, electromagnetic wave propagation, black hole perturbation theory in four and higher dimensions, quantum field theory in curved space-time and studies of D-branes. We first review analytic and numerical calculations of their eigenvalues and eigenfunctions in four dimensions, filling gaps in the existing literature when necessary. Then we compute the angular dependence of the spin-weighted spheroidal harmonics corresponding to slowly-damped quasinormal mode frequencies of the Kerr black hole, providing numerical tables and approximate formulas for their scalar products. Finally we present an exhaustive analytic and numerical study of scalar spheroidal harmonics in (n+4) dimensions.

description: Given a smooth compact Riemannian manifold $M$ and a Hamiltonian $H$ on the cotangent space $T^*M$, strictly convex and superlinear in the momentum variables, we prove uniqueness of certain ergodic invariant Lagrangian graphs within a given homology or cohomology class. In particular, in the context of quasi-integrable Hamiltonian systems, our result implies global uniqueness of Lagrangian KAM tori with rotation vector $ρ$. This result extends generically to the $C^0$-closure of KAM tori.

Multiple sources or late injection of short-lived r-nuclides in the early solar system?
Creators: name: Dauphas, Nicolas
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: Comparisons between the predicted abundances of short-lived r-nuclides (107Pd, 129I, 182Hf, and 244Pu) in the interstellar medium (ISM) and the observed abundances in the early solar system (ESS) conclusively showed that these nuclides cannot simply be derived from galactic chemical evolution (GCE) if synthesized in a unique stellar environment. It was thus suggested that two di erent types of stars were responsible for the production of light and heavy r-nuclides. Here, new constraints on the 244Pu=238U production ratio are used in an open nonlinear GCE model. It is shown that the two r-process scenario cannot explain the low abundance of 244Pu in the ESS and that this requires either than actinides be produced at an additional site (A-events) or more likely, that 129I and 244Pu be inherited from GCE and 107Pd and 182Hf be injected in the ESS by the explosion of a nearby supernova.

description: This article introduces the “Catalogue of Living Saints,” a wiki catalogue that provides knowledge about the lives of Castilian charismatic women, prior to Teresa of Ávila (d. 1582), who acquired reputations for holiness in their own times. The lives of these “holy” women show great contact between court and convent, and they contribute to better understanding the history of women and their subsequent impact on society. The collected lives appeared in a diversity of sources: manuscripts of the fifteenth through seventeenth centuries, including conventual books and compendia containing lives of saints, handwritten and printed chronicles of religious orders in sixteenth- and seventeenth-century Castile, and other works. Thus, the Catalogue recovers several texts that have never been printed before and that in most cases were never edited independently. Furthermore, it integrates the development of a database in order to understand the different proposed hagiographical models and their performative shape and spatial distribution of power. Additionally, this article discusses how gathering, editing, and reading the lives of these women via an open-access virtual tool creates a new hermeneutical framework regarding the materiality of the original codices and printed volumes. Finally, it proposes mitigation measures in the near future to bring contemporary reading practices (and interpretation) closer to historical ones.

description: The electric and the magnetic part of the Weyl tensor, as well as the invariants obtained from them, are calculated for the Bondi vacuum metric. One of the invariants vanishes identically and the other only exhibits contributions from terms of the Weyl tensor containing the static part of the field. It is shown that the necessary and sufficient condition for the spacetime to be purely electric is that such spacetime be static. It is also shown that the vanishing of the electric part implies Minkowski spacetime. Unlike the electric part, the magnetic part does not contain contributions from the static field. Finally a speculation about the link between the vorticity of world lines of observers at rest in a Bondi frame, and gravitational radiation, is presented.

description: A classical question for a Toeplitz matrix with given symbol is to compute asymptotics for the determinants of its reductions to finite rank. One can also consider how those asymptotics are affected when shifting an initial set of rows and columns (or, equivalently, asymptotics of their minors). Bump and Diaconis (Toeplitz minors, J. Combin. Theory Ser. A, 97 (2002), pp. 252--271) obtained a formula for such shifts involving Laguerre polynomials and sums over symmetric groups. They also showed how the Heine identity extends for such minors, which makes this question relevant to Random Matrix Theory. Independently, Tracy and Widom (On the limit of some Toeplitz-like determinants, SIAM J. Matrix Anal. Appl., 23 (2002), pp. 1194--1196) used the Wiener-Hopf factorization to express those shifts in terms of products of infinite matrices. We show directly why those two expressions are equal and uncover some structure in both formulas that was unknown to their authors. We introduce a mysterious differential operator on symmetric functions that is very similar to vertex operators. We show that the Bump-Diaconis-Tracy- Widom identity is a differentiated version of the classical Jacobi-Trudi identity.

description: Tuning one's shower in some hotels may turn into a challenging coordination game with imperfect information. The temperature sensitivity increases with the number of agents, making the problem possibly unlearnable. Because there is in practice a finite number of possible tap positions, identical agents are unlikely to reach even approximately their favorite water temperature. We show that a population of agents with homogeneous strategies is evolutionary unstable, which gives insights into the emergence of heterogeneity, the latter being tempting but risky.

description: On microscopic and mesoscopic scales, plastic flow of crystals is characterized by large intrinsic fluctuations. Deformation by crystallographic slip occurs in a sequence of intermittent bursts ('slip avalanches') with power-law size distribution. In the spatial domain, these avalanches produce characteristic deformation patterns in the form of slip lines and slip bands which exhibit long-range spatial correlations. We propose a generic continuum model which accounts for randomness in the local stress-strain relationships as well as for long-range internal stresses that arise from the ensuing plastic strain heterogeneities. The model parameters are related to the local dynamics and interactions of lattice dislocations. The model explains experimental observations on slip avalanches as well as the associated slip and surface pattern morphologies.
Search for long-lived particles using displaced jets in proton-proton collisions at $\sqrt{s} = $ 13 TeV

Year: 2020
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: An inclusive search is presented for long-lived particles using displaced jets. The search uses a data sample collected with the CMS detector at the CERN LHC in 2017 and 2018, from proton-proton collisions at a center-of-mass energy of 13 TeV. The results of this search are combined with those of a previous search using a data sample collected with the CMS detector in 2016, yielding a total integrated luminosity of 132 fb$^{-1}$. The analysis searches for the distinctive topology of displaced tracks and displaced vertices associated with a dijet system. For a simplified model, where pair-produced long-lived neutral particles decay into quark-antiquark pairs, pair production cross sections larger than 0.07 fb are excluded at 95% confidence level (CL) for long-lived particle masses larger than 500 GeV and mean proper decay lengths between 2 and 250 mm. For a model where the standard model-like Higgs boson decays to two long-lived scalar particles that each decays to a quark-antiquark pair, branching fractions larger than 1% are excluded at 95% CL for mean proper decay lengths between 1 mm and 340 mm. A group of supersymmetric models with pair-produced long-lived gluinos or top squarks decaying into various final-state topologies containing displaced jets is also tested. Gluino masses up to 2500 GeV and top squark masses up to 1600 GeV are excluded at 95% CL for mean proper decay lengths between 3 and 300 mm. The highest lower bounds on mass reach 2600 GeV for long-lived gluinos and 1800 GeV for long-lived top squarks. These are the most stringent limits to date on these models.

These patterns allow us to demonstrate how key principles governing crystallization have to be adapted in order to accomplish solidification in restricted geometries. He, Ar, and the spherical close packed phases of CO and N2 adjust to the pore geometry by introducing a sizeable amount of stacking faults. For the pore solidified, medium-length chain-like n-C19H40 we observe a close packed structure without lamellar ordering, whereas for the short-chain C9H20 the layering principle survives, albeit in a modified fashion compared to the bulk phase.

description: This article provides the first in-depth study of historic content and materials used in the production of a liturgical codex from the collection of manuscripts of the Monastery of Alcobaça: the Psalter-hymnal (Lisbon, National Library, Alc. 11). To answer provenance questions and trace the manuscript’s history, a multidisciplinary team studied the entire procedure of making the codex, which went from in-depth textual, liturgical, and codicological analyses, to examining material composition and bookbinding methods with complementary analytical techniques. The team was able to track the manuscript’s historical trajectory through successive additions and interventions/alterations. Interpretation of the historic information and the resulting technical data confirmed the belief that this is a twelfth-century manuscript produced in the scriptorium of Alcobaça and underlined the role that the manuscript played in this Cistercian monastery during the Middle Ages, and possibly throughout the following centuries. This led the team to approach the codex’s “cultural significance” and perceive later alterations and interventions as evidence of the monks’ intensive use of this manuscript and the great care they took to preserve their monastic library. The new data and knowledge acquired about this precious codex proved to be fundamental for future digital access policy definition and the conservation making decision.

description: It is shown that the theory of real symmetric second-order elliptic operators in divergence form on $\Ri^d$ can be formulated in terms of a regular strongly local Dirichlet form irregardless of the order of degeneracy. The behaviour of the corresponding evolution semigroup $S_t$ can be described in terms of a function $(A,B) \mapsto d(A ;B)\in[0,\infty]$ over pairs of measurable subsets of $\Ri^d$. Then \[ |(ϕ_A,S_tϕ_B)|\leq e^{-d(A;B)^2(4t)^{-1}}\|ϕ_A\|_2\|ϕ_B\|_2 \] for all $t>0$ and all $ϕ_A\in L_2(A)$, $ϕ_B\in L_2(B)$. Moreover $S_tL_2(A)\subseteq L_2(A)$ for all $t>0$ if and only if $d(A ;A^c)=\infty$ where $A^c$ denotes the complement of $A$.

description: In this paper the impact of public policies such as subsidies and taxation on invasive species management is explored in a Markov chain framework. Private agents react to public incentives based upon their long term expected profits and have the option of taking measures such as abatement, monitoring and reporting. Conditions for perverse incentives are derived. The impact of sequencing of taxation and subsides on spread of risks if explored. One key finding of this paper is that excessive regulation may exacerbate the invasive species problem.

description: Honig ist ein lebensmittelrechtlich stark reglementiertes Nahrungsmittel. Da das im Honig enthaltene Enzym Saccharase sehr temperaturempfindlich ist, kann seine Aktivität als Parameter zur Beurteilung seiner Frische und einer sachgemäßen Wärmebehandlung beim Abfüllen herangezogen werden. Je höher die Saccharaseaktivität eines Honigs ist, desto höher ist seine Qualität. Sie ist ein wichtiges Kriterium dafür, ob ein Honig die Bezeichnung „Auslese“ oder „Premium“ erhalten darf. In diesem Beitrag wird die quantitative Bestimmung der Saccharaseaktivität als Schulexperiment vorgestellt. Schwerpunkt des Unterrichtsmodells ist die Erarbeitung der Methodik, um diese je nach Auswahl der zu testenden Honige zur Klärung unterschiedlicher Fragestellungen nutzen zu können. Das Material eignet sich auch für asynchrones Arbeiten, z.B. im Distanzunterricht und bei Verzicht auf die praktische Durchführung der Untersuchung.

description: We present a innovative relationship between ground states of the Ising model and dimer coverings which sheds new light on the Ising Models with highly degenerated ground states and enables one to construct such models. Thanks to this relationship we also find the generating function for dimers as the appropriate limit of the free energy per spin for the Ising model.
Planning low-carbon distributed power systems: Evaluating the role of energy storage

description: This paper introduces a mathematical formulation of energy storage systems into a generation capacity expansion framework to evaluate the role of energy storage in the decarbonization of distributed power systems. The modeling framework accounts for dynamic charging/discharging efficiencies and maximum cycling powers as well as cycle and calendar degradation of a Li-ion battery system. Results from a small-scale distributed power system indicate that incorporating the dynamic efficiencies and cycling powers of batteries in the generation planning problem does not significantly change the optimal generation portfolio, while adding substantial computational burden. In contrast, accounting for battery degradation leads to substantially different generation expansion outcomes, especially in deep decarbonization scenarios with larger energy storage capacities. Under the assumptions used in this study, it is found that battery energy storage is economically viable for 2020 only under strict carbon emission constraints. In contrast, given the projected technology advances and corresponding cost reductions, battery energy storage exhibits an attractive option to enable deep decarbonization in 2050.

description: The ornamental commodity in Puerto Rico is valued for its economic contribution in the agricultural sector, its contribution to the esthetics of natural scenarios that impact the tourism sector, and for its environmental role. In the fiscal year 2001, ornamentals generated 4.8% of the total Agricultural Gross Product. In that year the production value at farm level was $34.1 million, the export value $0.5 million, and the import value $11.5 millions. Of the local production value, 1.5% was exported and 34.3% of the ornamental local market value was imported. The active trade traffic in Puerto Rico is a factor that increases the risk of the introduction of invasive species that affect the agricultural sector. It is necessary to estimate the economic impact of the established invasive species and those with high potential for introduction. The economic analysis must consider the impact on production, on market, and on the environment. The direct and indirect impact on market and non-market areas has to be estimated. The study presented in this paper pretends to gather economic data on the ornamental commodity and biological data on invasive pests and diseases to initiate the development of a comprehensive species risk management framework that incorporates the economic impact of invasive species.

subject: FOS: Computer and information sciences

description: Background and Objective: Deep learning enables tremendous progress in medical image analysis. One driving force of this progress are open-source frameworks like TensorFlow and PyTorch. However, these frameworks rarely address issues specific to the domain of medical image analysis, such as 3-D data handling and distance metrics for evaluation. pymia, an open-source Python package, tries to address these issues by providing flexible data handling and evaluation independent of the deep learning framework. Methods: The pymia package provides data handling and evaluation functionalities. The data handling allows flexible medical image handling in every commonly used format (e.g., 2-D, 2.5-D, and 3-D; full- or patch-wise). Even data beyond images like demographics or clinical reports can easily be integrated into deep learning pipelines. The evaluation allows stand-alone result calculation and reporting, as well as performance monitoring during training using a vast amount of domain-specific metrics for segmentation, reconstruction, and regression. Results: The pymia package is highly flexible, allows for fast prototyping, and reduces the burden of implementing data handling routines and evaluation methods. While data handling and evaluation are independent of the deep learning framework used, they can easily be integrated into TensorFlow and PyTorch pipelines. The developed package was successfully used in a variety of research projects for segmentation, reconstruction, and regression. Conclusions: The pymia package fills the gap of current deep learning frameworks regarding data handling and evaluation in medical image analysis. It is available at https://github.com/rundherum/pymia and can directly be installed from the Python Package Index using pip install pymia.

description: Since the WTO's inception in 1995, the number of cases it has dealt with has exceeded the number of disputes under the GATT. This suggests that Members have found the WTO dispute settlement system a useful means to pursue their interests. In this paper, we analyze an ongoing WTO dispute to illustrate the economic and political costs and benefits that accrue to parties when they engage themselves into the formal dispute process. We draw on the Philippine-Australian case, which challenges the latter's quarantine policy on fresh fruit and vegetables, to understand further how the WTO dispute settlement system affects state behavior and litigation patterns. This particular case is also of keen interest to a number of countries, including the EC, US, Canada, Ecuador, Thailand, China, India and Chile.
Sufficient Conditions for Fast Switching Synchronization in Time Varying Network Topologies

description: In previous work, empirical evidence indicated that a time-varying network could propagate sufficient information to allow synchronization of the sometimes coupled oscillators, despite an instantaneously disconnected topology. We prove here that if the network of oscillators synchronizes for the static time-average of the topology, then the network will synchronize with the time-varying topology if the time-average is achieved sufficiently fast. Fast switching, fast on the time-scale of the coupled oscillators, overcomes the descychnronizing decoherence suggested by disconnected instantaneous networks. This result agrees in spirit with that of where empirical evidence suggested that a moving averaged graph Laplacian could be used in the master-stability function analysis. A new fast switching stability criterion here-in gives sufficiency of a fast-switching network leading to synchronization. Although this sufficient condition appears to be very conservative, it provides new insights about the requirements for synchronization when the network topology is time-varying. In particular, it can be shown that networks of oscillators can synchronize even if at every point in time the frozen-time network topology is insufficiently connected to achieve synchronization.

description: The Morishima elasticity of substitution (MES) is estimated to address factor substitutability in Florida agriculture during 1960-1999. By adopting a profit maximization model of induced innovation theory, the MES's between hired and self-employed labor and the MES's between labor and capital provide implications for future immigration policies.
