description: We analyse two issues that arise in the context of (matrix) string theories in plane wave backgrounds, namely (1) the use of Brinkmann- versus Rosen-variables in the quantum theory for general plane waves (which we settle conclusively in favour of Brinkmann variables), and (2) the regularisation of the quantum dynamics for a certain class of singular plane waves (discussing the benefits and limitations of regularisations of the plane-wave metric itself).

description: We study the dynamics of the spin and cavity field of the Tavis-Cummings model using quasi-probability distribution functions and second order coherence function, respectively. The effects of (non)-Markovian noise are considered. The relationship between the evolution of the cavity photon number, spin excitation, and atomic inversion under different quantum channels is observed. The equal-time second-order coherence function is used to study the sub-Poissonian behavior of light, and is compared with the two-time second-order coherence function in order to highlight the (anti)-bunching properties of the cavity radiation.

Pantheismus

Publisher: name: Online Encyclopedia Philosophy of Nature

description: Unter Pantheismus, von griechisch πα̃ν (pan), „alles“, und ϑεός (theos), „Gott“, versteht man eine religionsphilosophische Lehre, in der Gott und Welt, Gott und Natur gleichgesetzt werden. Hervorgegangen ist der Pantheismus-Begriff aus den religionsphilosophischen Kontroversen des frühen 18. Jahrhunderts und erscheint zuerst bei dem rationalistischen Philosophen John Toland. Als All-Einheitslehre behauptet der Pantheismus gegenüber den dualistischen Denkweisen und insbesondere der jüdisch-christlichen Schöpfungstheologie die Immanenz Gottes und die Ununterscheidbarkeit von göttlichem und naturgesetzlichem Wirken. Als Sammelname für eine Vielzahl von Erscheinungsformen ist er in historischer wie systematischer Hinsicht unscharf, und je nach Ausprägung berührt er sich mit dem Atheismus und Materialismus (Vorrang des Weltlichen), dem Akosmismus (Lehre von Gott als einziger Wirklichkeit) und der Mystik (spirituelle Vereinigung mit Gott), dem Panentheismus (All-in-Gott-Lehre), dem Panpsychismus (Allbeseeltheitslehre) oder dem Monismus (Einheitslehre). Verweist der Pantheismus entstehungsgeschichtlich auf die neuzeitliche Schnittstelle von Philosophie, Theologie und Naturwissenschaft, so lassen sich pantheistische Vorstellungen doch auch in der Geschichte des europäischen und außereuropäischen Denkens finden. Im Zusammenhang mit der Spinoza-Renaissance erlebt der Pantheismus vor allem im Deutschland des 18. und 19. Jahrhunderts eine beispiellose Aufwertung, die ihm weit über seinen okkasionellen Ursprung hinaus kulturhistorisches Gewicht verleiht.

A phase-field approximation of the Willmore flow with volume and area constraints

Year: 2012
Subjects: subject: Analysis of PDEs (math.AP)

description: The well-posedness of a phase-field approximation to the Willmore flow with area and volume constraints is established when the functional approximating the area has no critical point satisfying the two constraints. The existence proof relies on the underlying gradient flow structure of the problem: the time discrete approximation is solved by a variational minimization principle. The main difficulty stems from the nonlinearity of the area constraint.

description: We study the problem of graph structure identification, i.e., of recovering the graph of dependencies among time series. We model these time series data as components of the state of linear stochastic networked dynamical systems. We assume partial observability, where the state evolution of only a subset of nodes comprising the network is observed. We devise a new feature vector computed from the observed time series and prove that these features are linearly separable, i.e., there exists a hyperplane that separates the cluster of features associated with connected pairs of nodes from those associated with disconnected pairs. This renders the features amenable to train a variety of classifiers to perform causal inference. In particular, we use these features to train Convolutional Neural Networks (CNNs). The resulting causal inference mechanism outperforms state-of-the-art counterparts w.r.t. sample-complexity. The trained CNNs generalize well over structurally distinct networks (dense or sparse) and noise-level profiles. Remarkably, they also generalize well to real-world networks while trained over a synthetic network (realization of a random graph). Finally, the proposed method consistently reconstructs the graph in a pairwise manner, that is, by deciding if an edge or arrow is present or absent in each pair of nodes, from the corresponding time series of each pair. This fits the framework of large-scale systems, where observation or processing of all nodes in the network is prohibitive.

description: Lo scambio di studenti con la Cina nell’istruzione terziaria è oggi al centro di considerazioni sempre più attente e prudenti da parte dei paesi partner. I driver per la promozione degli scambi accademici sono infatti profondamente mutati nell’ultimo decennio. Le tensioni tra Pechino e i paesi dell’alleanza atlantica, che trovano un riflesso nella rinnovata attenzione dell’Unione Europea ai rischi dell’interdipendenza in campo scientifico, toccano istituzioni universitarie e centri di ricerca, influenzandone la struttura degli incentivi. A ciò si è aggiunta l’emergenza pandemica che ha virtualizzato i programmi di mobilità riducendo drasticamente il flusso di studenti da e verso la Cina. Osservando le diverse posizioni e interessi in gioco, gli autori esaminano quali sono i fattori di disaccoppiamento tra Cina e Occidente nell’istruzione terziaria e quali le spinte a mantenere un certo grado di interazione e interdipendenza. L’articolo analizza inoltre il caso studio dei programmi di mobilità dell’Università di Torino, per verificare come il mutato scenario globale si proietti su uno dei contesti di punta nello scambio accademico sino-italiano.

A critical Schrödinger cat qubit

description: Encoding quantum information onto bosonic systems is a promising route to quantum error correction. In a cat code, this encoding relies on the confinement of the system's dynamics onto the two-dimensional manifold spanned by Schrödinger cats of opposite parity. In dissipative cat qubits, an engineered dissipation scheme combining two-photon drive and loss has been used to autonomously stabilize this manifold, ensuring passive protection against bit-flip errors, regardless of their origin. In Kerr cat qubits, where highly-performing gates can be engineered, two-photon drive and Kerr nonlinearity cooperate to confine the system to a two-fold degenerate ground state manifold spanned by cats of opposite parity. Dissipative, Hamiltonian, and hybrid confinements have been investigated at resonance. Here, we propose a critical cat code, where both two-photon loss and Kerr nonlinearity are present, and the two-photon drive is allowed to be out of resonance. The performance of this code is assessed via the spectral theory of Liouvillians in all configurations, from the purely dissipative to the Kerr limit. We show that large detunings and small, but non-negligible, two-photon loss rates are fundamental to achieve optimal performance. We demonstrate that the competition between nonlinearity and detuning results in a first-order dissipative phase transition, leading to a squeezed vacuum steady state. To achieve the maximal suppression of the logical bit-flip rate requires initializing the system in the metastable state emerging from the first-order transition, and we detail a protocol to do so. Efficiently operating over a broad range of detuning values, the critical cat code is particularly resistant to random frequency shifts characterizing multiple-qubit operations, opening venues for the realization of reliable protocols for scalable and concatenated bosonic qubit architectures.

description: The color spectrum has been used as a paradigm to exemplify two basic theoretical approaches (the universalist and the relativist) to the relationship between language and cognition and language and culture. Although both theoretical approaches appeared at first blush to be validated by the use of the color spectrum as a supportive example, upon more detailed examination, neither theoretical disposition is well supported, partly because color is so poorly understood as a natural phenomenon. This thesis works from both theoretical positions in an attempt to understand the symbolic uses of color in both language and culture in terms of the apprehension of color itself. Thus, this thesis is an attempt to understand the human uses of the polychromatic sensitivity of that organism and is not meant to use that sensitivity as exemplar of any particular theoretical predisposition . The conclusions regarding the evolution of color vision are speculative and properly so in what is necessarily a seminal work. The final conclusions regarding the universalist/ relativist debate are based on a rather massive body of data correlating cultural symbols with linguistic symbols for colors, and are of a common sense variety which occupies the middle ground between the extremes of the other two positions, both of which are partly right and, in the final analysis, uncontradictory.

description: Adolf Karol Sandoz był jednym z dziewiętnastowiecznych artystów polskiego pochodzenia, który swoje życie i karierę artystyczną związał z Francją. W Paryżu studiował malarstwo i architekturę, a następnie pracował jako ilustrator. Możemy umieścić go także w kręgu artystów-podróżników, którzy poszukiwali nowych źródeł inspiracji w krajach Orientu. W latach 1879 i 1881 Sandoz podróżował po Algierii. Swoje wrażenia z pierwszej wyprawy barwnie opisał we wspomnieniach opublikowanych na łamach krakowskiego dziennika Czas. Plonem artystycznym wypraw były obrazy o tematyce rodzajowej miedzy innymi: Wnętrze mieszkania w Biskrze, Tancerka z plemiona Uled Nail, Arabka przy kolebce, Poranek w pustyni saharyjskiej, Wieczór w pustyni saharyjskiej, Oaza, Nad brzegiem Ued w oazie El-Kantary, Szejkowa El-Kantary. Obecnie prace te pojawiają się na aukcjach antykwarycznych, są znane z reprodukcji lub jedynie z opisów. Sandoz wystawiał je w Paryżu, Warszawie, Krakowie i Lwowie, gdzie spotkały się z zainteresowaniem krytyki artystycznej. Celem tekstu jest przybliżenie podróży Sandoza do Algierii, analiza jego obrazów o tematyce egzotycznej i umieszczenie ich w szerszym kontekście malarstwa orientalistycznego. Nakreślona zostanie również historia podróży artystycznych malarzy dziewiętnastowiecznych, w tym polskich, do Algierii.

Year: 2017

description: Adolf Karol Sandoz was a 19th-century Polish artist who spent his life and developed his artistic career in France. In Paris, he studied painting and architecture, and worked as a professional illustrator. He can also be linked with a circle of artist-travellers, who searched for new sources of inspiration in the Orient. In 1879 and 1881, Sandoz travelled in Algeria. He described his impressions from the first journey in vividly written memoires published by the Krakow journal Czas. His travels inspired several genre paintings, including: Interior of a House in Biskra, Dancer from the Uled Nail Tribe, Arab Woman by a Cradle, Morning in the Sahara, Evening in the Sahara, Oasis, On the Oued Riverbank at El Kantara Oasis, and Sheik Mistress of El Kantara. At present, his works emerge at art auctions, are known from reproductions, or only from descriptions. Sandoz exhibited in Paris, Warsaw, Krakow, and Lviv, where he was appreciated by art critics. The aim of this article is to introduce Sandoz’s journey to Algeria, analyse his paintings with exotic subject matter, and locate them within a wider context of orientalist painting. It will also present the history of artistic travel to Algeria undertaken by 19th-century painters, including those from Poland.

description: We discover a "no semistability at infinity" phenomenon for complete Calabi-Yau metrics asymptotic to cones, by eliminating the possible appearance of an intermediate K-semistable cone in the 2-step degeneration theory developed by Donaldson and the first author. It is in sharp contrast to the setting of local singularities of Kähler-Einstein metrics. A byproduct of the proof is a polynomial convergence rate to the asymptotic cone for such manifolds, which bridges the gap between the general theory of Colding-Minicozzi and the classification results of Conlon-Hein.

description: The most significant Danish warrior burial is arguably the Memorial Grove in Ryvangen for members of the Danish resistance movement during World War II. This article places the memorial within Danish history and the reception of WWII and argues for its particular qualities as a modernist re-working of a discredited monumental tradition with a particular focus on plain materials and a low architectural scale. The memorial affords a heightened sense of materiality and nature as a practical example of a philosophy of presence. The park-like memorial can also be seen as a performative ground for instilling aspects of identity and collective memory for both individuals and Danish society. Future uses of the site can either go in the direction of recreation or toward immersive education.

description: Intense few-to-sub-femtosecond soft x-ray pulses can produce neutral, two-site excited double-core-hole states by promoting two core electrons to the same unoccupied molecular orbital. We theoretically investigate double nitrogen K-edge excitations of nitrous oxide (N2O) with multiconfigurational electronic structure calculations. We show that the second core-excitation energy is reduced with respect to its ground state value. A site-selective double core-excitation mechanism using intense few-femtosecond x-rays is investigated using time-dependent Schrodinger equation (TDSE) simulations. The subsequent two-step Auger-Meitner and two-electrons-one-electron decay spectra of the double core-excited states are analyzed using a Mulliken population analysis of the multiconfirational wavefunctions. The change in the electron emission lineshape between the absorption of 1 or 2 photons in the resonant core-excitation is predicted by combining this approach with the TDSE simulations. We examine the possibility of resolving the double core-excited states with x-ray pump-probe techniques by calculating the chemical shifts of the core-electron binding energy of the core-excited states and decay products.

description: We present 16 GHz (1.9 cm) deep radio continuum observations made with the Arcminute Microkelvin Imager (AMI) of a sample of low-mass young stars driving jets. We combine these new data with archival information from an extensive literature search to examine spectral energy distributions (SEDs) for each source and calculate both the radio and sub-mm spectral indices in two different scenarios: (1) fixing the dust temperature (Td) according to evolutionary class; (2) allowing Td to vary. We use the results of this analysis to place constraints on the physical mechanisms responsible for the radio emission. From AMI data alone, as well as from model fitting to the full SED in both scenarios, we find that 80 per cent of the objects in this sample have spectral indices consistent with free-free emission. We find an average spectral index in both Td scenarios consistent with free-free emission. We examine correlations of the radio luminosity with bolometric luminosity, envelope mass, and outflow force and find that these data are consistent with the strong correlation with envelope mass seen in lower luminosity samples. We examine the errors associated with determining the radio luminosity and find that the dominant source of error is the uncertainty on the opacity index, beta. We examine the SEDs for variability in these young objects, and find evidence for possible radio flare events in the histories of L1551 IRS 5 and Serpens SMM 1.

description: In extreme scattering events, the brightness of a compact radio source drops significantly, as light is refracted out of the line of sight by foreground plasma lenses. Despite recent efforts, the nature of these lenses has remained a puzzle, because any roughly round lens would be so highly overpressurized relative to the interstellar medium that it could only exist for about a year. This, combined with a lack of constraints on distances and velocities, has led to a plethora of theoretical models. We present observations of a dramatic double-lensing event in pulsar PSR~B0834+06 and use a novel phase-retrieval technique to show that the data can be reproduced remarkably well with a two-screen model: one screen with many small lenses and another with a single, strong one. We further show that the latter lens is so strong that it would inevitably cause extreme scattering events. Our observations show that the lens moves slowly and is highly elongated on the sky. If similarly elongated along the line of sight, as would arise naturally from a sheet of plasma viewed nearly edge-on, no large over-pressure is required and hence the lens could be long-lived. Our new technique opens up the possibility of probing interstellar plasma structures in detail, leading to understanding crucial for high-precision pulsar timing and the subsequent detection of gravitational waves.

description: By applying the methods of categorisation, comparison and analysis of written sources, this article aims to reveal how Surrealist artistic ideas may have influenced – through the intermediary of the Postmodern movement – architectural trends up to the present time. The paper is organized into three parts, each dedicated to one of the most important Surrealist architectural concepts: the synthesis of the arts, fluidity, and formalistic superficiality and spontaneity. Each section describes how these ideas were underlined in Surrealist art and theoretical texts, compares them to some examples of Postmodern and contemporary architecture, and explains how these ideas were nurtured from the time they emerged until the time they materialized in architectural design.

Questo specifico centro è inoltre affiliato alla rete di centri servizi per cinesi residenti all’estero organizzato dalla Municipalità di Wenzhou, qualificandosi come un Wenzhou Overseas Chinese Center. Vi si offrono servizi come la prenotazione del rinnovo del passaporto, la delega per la richiesta del visto (per chi è di origine cinese, ma cittadino italiano), l’assicurazione per gli studenti cinesi all’estero, assistenza legale, ecc. Questi centri, per erogare tali servizi, non solo devono poter contare su raccordi organizzativi con il Consolato cinese di Milano, ma anche su canali di comunicazione diretti con le autorità delle proprie zone di origine in Cina. In nessun caso si tratta di attività di carattere clandestino o “segreto”.

description: In the context of the upgrade of the Large Hadron Collider at CERN for high-luminosity operation, the particle detectors have to cope with much higher data rates and therefore need to upgrade their data acquisition systems. This upgrade is taken as an opportunity to exchange the currently used highly customized hardware by commercial solutions. Nevertheless, some part of the data processing still needs to be done within Field Programmable Gate Arrays (FPGA), requiring the transfer of data between the FPGAs and the commercial servers. This paper reports on a study of direct data transmission from FPGAs to servers via a commercial network. Large data buffers as required for reliable data-transmission protocols are avoided by using an emerging technique named eXpress Data Path (XDP). Based on XDP, the transmission of 5.2 PB (i.e. 2.92 * 10^{12} packets) was achieved within 168 h without a single missing packet.

description: Digital radio detection of cosmic-ray air showers has emerged as an alternative technique in high-energy astroparticle physics. Estimation of the detection efficiency of cosmic-ray radio arrays is one of the few remaining challenges regarding this technique. To address this problem, we developed a model based on the explicit probabilistic treatment of key elements of the radio technique for air showers: the footprint of the radio signal on ground, the detection of the signal in an individual antenna, and the detection criterion on the level of the entire array. The model allows for estimation of sky regions of full efficiency and can be used to compute the aperture of the array, which is essential to measure the absolute flux of cosmic rays. We also present a semi-analytical method that we apply to the generic model, to calculate the efficiency and aperture with high accuracy and reasonable calculation time. The model in this paper is applied to the Tunka-Rex array as example instrument and validated against Monte Carlo simulations. The validation shows that the model performs well, in particular, in the prediction of regions with full efficiency. It can thus be applied to other antenna arrays to facilitate the measurement of absolute cosmic-ray fluxes and to minimize a selection bias in cosmic-ray studies.

description: When Hans Scharoun, Walter Gropius, and Ludwig Mies van der Rohe presented their emblematic works of architecture at major programmatic exhibitions in Breslau (1929), Paris (1930) and Berlin (1931), they chose single-person homes and apartments to represent them. This type of structure was conceived specifically to accommodate the lifestyle of a modern nomad, unattached to one single location, material possessions, familial or national bonds, a person attuned to his time. As will be highlighted in this article, this new type of architecture and design reflected a number of contemporary social theoretical positions on the human condition in the twentieth century.

description: Time-reflection is a uniform inversion of the temporal evolution of a signal, which arises when an abrupt change in the properties of the host material occurs uniformly in space. At such a time-interface, a portion of the input signal is time-reversed, and its frequency spectrum is homogeneously translated while its momentum is conserved, forming the temporal counterpart of a spatial interface. Combinations of time-interfaces, forming time-metamaterials and Floquet matter, exploit the interference of multiple time-reflections for extreme wave manipulation, leveraging time as a new degree of freedom. Here, we report the observation of photonic time-reflection and associated broadband frequency translation in a switched transmission-line metamaterial whose effective capacitance is homogeneously and abruptly changed via a synchronized array of switches. A pair of temporal interfaces are combined to demonstrate time-reflection-induced wave interference, realizing the temporal counterpart of a Fabry-Perot cavity. Our results establish the foundational building blocks to realize time-metamaterials and Floquet photonic crystals, with opportunities for extreme photon manipulation in space and time.

description: Observations with Subaru telescope have detected surprisingly strong Lyman continuum (LyC; $\sim900$ Å in the rest-frame) from some Lyman $α$ emitters (LAEs) at $z=3.1$. We have examined the stellar population which simultaneously accounts for the strength of the LyC and the spectral slope of non-ionizing ultraviolet of the LAEs. As a result, we have found that stellar populations with metallicity $Z\geq1/50 Z_\odot$ can explain the observed LyC strength only with a very top-heavy initial mass function (IMF; $< m > \sim 50 M_\odot$). However, the critical metallicity for such an IMF is expected to be much lower. A very young ($\sim1$ Myr) and massive ($\sim100$ $M_\odot$) extremely metal-poor ($Z\leq5\times10^{-4}Z_\odot$) or metal-free (so-called Population III) stellar population can also reproduce the observed LyC strength if the mass fraction of such 'primordial' stellar population is $\sim1$% in total stellar mass of the LAEs.

A Finite Element Configuration Interaction Method for Wigner Localization

description: The Wigner localization is an electron phase at low densities when the electrons are sharply localized around equilibrium positions. The simulation of the Wigner localization phenomenon requires careful treatment of the many-body correlations, as the electron-electron interaction dominates the system. This work proposes a numerical algorithm to study the electron ground states of the Wigner molecules. The main features of our algorithm are three-fold: (i) a finite element discretization of the one-body space such that the sharp localization can be captured; (ii) a good initial state obtained by exploiting the strongly correlated limit; and (iii) a selected configuration interaction method by choosing the Slater determinants from (stochastic) gradients. Numerical experiments for some typical one-dimensional quantum wires and two-dimensional circular quantum dots are provided to show the efficiency of our algorithm.

description: The cooling of neutron stars (hereafter NS) has the potential to reveal important features of superdense matter. Their surface temperatures are known for a fair sample of NS with ages $\leq 10^{6} \, {\it{yr}}$, and with a few exceptions, can be accommodated by standard cooling mechanisms (neutrino+photon emission without internal heating). However, for the older objects it is necessary to consider some internal heating to explain surface temperatures higher than expected. We revisit in this paper the kinetic heating by fermionic dark matter, rotochemical heating and magnetic field decay. We found that NS slightly older than $\sim 10^{6} \, {\it{yr}}$ can be explained by them, but the older ``black widow'' systems are much hotter than the values predicted by these three mechanisms, pointing towards a yet unknown heating factor for old NS.

 Known to Barneby (1991) only from the type locality in the Chaco of west-central Paraguay. A single collection (J. Pensiero & G. Marino 4379, NY) from Chuquisaca determined by Barneby in 1994, is apparently the first record for Bolivia. Four additional collections (J.R.I. Wood & D. Villarroel 25467, J.R.I. Wood & Pozo 25985, J.R.I. Wood et al. 26573, J.R.I. Wood et al. 26582, LPB, K) from near Rincón del Tigre as well as collections from near Roboré (J.R.I. Wood & M. Mendoza 27317, LPB, K) and from Cordillera Province (Fuentes 3384, USZ) confirm that this species is widespread and locally abundant on sandy soils in open ruderal habitats around the fringes of the Chaco, and is thus well named.

description: We derive exact equations that determine the spectra of undirected and directed sparsely connected regular graphs containing loops of arbitrary length. The implications of our results to the structural and dynamical properties of networks are discussed by showing how loops influence the size of the spectral gap and the propensity for synchronization. Analytical formulas for the spectrum are obtained for specific length of the loops.

Two distinct halo populations in the solar neighborhood. III. Evidence from stellar ages and orbital parameters

description: In Papers I and II of this series, the existence of two distinct halo populations of stars have been found in the solar neighborhood. Precise relative ages and orbital parameters are determined for 67 halo and 16 thick-disk stars having metallicities in the range -1.4 < [Fe/H] < -0.4 to better understand the context of the two halo populations in the formation and evolution of the Galaxy. Ages are derived by comparing the positions of stars in the logT_{eff}-log(g) diagram with isochrones from the Y^2 models interpolated to the exact [Fe/H] and [alpha/Fe] values of each star. Possible systematic errors in T_{eff} and log(g) are considered and corrected. With space velocities from Paper I as initial conditions, orbital integrations have been carried out using a detailed, observationally constrained Milky Way model including a bar and spiral arms. The `high-alpha' halo stars have ages 2-3 Gyr larger than the `low-alpha' ones. The orbital parameters show very distinct differences between the `high-alpha' and `low-alpha' halo stars. The `low-alpha' ones have r_{max}'s to 30-40 kpc, z_{max}'s to approx. 18 kpc, and e_{max}'s clumped at values greater than 0.85, while the `high-alpha' ones, r_{max}'s to about 16 kpc, z_{max}'s to 6-8 kpc, and e_{max} more or less uniformly distributed over 0.4-1.0. A dual in situ-plus-accretion formation scenario best explains the existence and characteristics of these two halo populations, but one remaining defect is that this model is not consistent regarding the r_{max}'s obtained for the in situ `high-alpha' component; the predicted values are too small. It appears that omega Cen may have contributed in a significant way to the existence of the `low-alpha' component; recent models, including dynamical friction and tidal stripping, have produced orbital parameters as great as those of the `low-alpha' component.

A new version of an old modal incompleteness theorem

description: Thomason \cite{Thomason74} showed that a certain modal logic $\mathbf{L}\subset \mathbf{S4}$ is incomplete with respect to Kripke semantics. Later Gerson \cite{Gerson75} showed that $\mathbf{L}$ is also incomplete with respect to neighborhood semantics. In this paper we show that $\mathbf{L}$ is in fact incomplete with respect to any class of complete Boolean algebras with operators, i.e. that it is completely incomplete.
