description: The core of planetary nebula NGC 6302 is filled with high-excitation photoionised gas at low expansion velocities. It represents a unique astrophysical situation in which to search for hyperfine structure (HFS) in coronal emission lines from highly ionised species. HFS is otherwise blended by thermal or velocity broadening. Spectra containing [AlVI]~3.66um 3P2-3P1, obtained with Phoenix on Gemini-South at resolving powers of up to 75000, resolve the line into five hyperfine components separated by 20 to 60km/s due to the coupling of the I=5/2 nuclear spin of 27Al with the total electronic angular momentum J. 26Al has a different nuclear spin of I=5, and a different HFS, which allows us to place a 3sigma upper limit on the 26Al/27Al abundance ratio of 1/33. We measure the HFS magnetic-dipole coupling constants for [AlVI], and provide the first estimates of the electric-quadrupole HFS coupling constants obtained through astronomical observations of an atomic transition.

description: The present contribution is mainly intended to illustrate how some recent discoveries in the field of neurosciences have revolutionized our ideas about perception, action and cognition, and how these new neuro-scientific perspectives can shed light on the human relationship to art and aesthetics, in the frame of an approach known as "experimental aesthetics". Experimental aesthetics addresses the problem of artistic images by investigating the brain-body physiological correlates of the aesthetic experience and human creativity, providing a perspective that is complementary, and not in opposition, to the humanistic one on the arts and the aesthetic.

description: A novel approach to the fabrication of GaNxAs1-x quantum dots and wires via ion beam patterning is presented. Photomodulated reflectance spectra confirm that N can be released from the As sublattice of an MBE-grown GaNxAs1-x film by amorphization through ion implantation followed by regrowth upon rapid thermal annealing (RTA). Amorphization may be achieved with a focused ion beam (FIB), which is used to implant Ga ions in patterned lines such that annealing produces GaAs regions within a GaNxAs1-x film. The profiles of these amorphized lines are dependent upon the dose implanted, and the film reaches a damage threshold during RTA due to excess Ga. By altering the FIB implantation pattern, quantum dots or wires may be fabricated.

Two Forms of Gesture: Notes on Aby Warburg and Walter Benjamin

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2017

description: The paper both connects and disassociates the work of Walter Benjamin and Aby Warburg. There are two interrelated undertakings. The first involves the relationship between philosophy and art history and thus how art history figures within the philosophical. The second pertains to the status of the image. Part of the argument to be advanced is that an engagement with philosophical approach to art history yields a concern with the image in which it is the image's material presence that proves decisive. Indeed, it is by insisting on the object's materiality that it then becomes possible to locate the effective presence of the gesture as integral to the work of art. The contention is that gesture is the intersection of art's material presence and the concerns of meaning. The paper us develop via an engagement with works by Edgar Degas and Luca Signorelli.

description: In this paper we study some models where non-Abelian gauge vector fields endowed with a SU(2) group representation are the unique source of inflation and dark energy. These models were first introduced under the name of gaugeflation and gaugessence, respectively. Although several realizations of these models have been discussed, not all available parameters and initial conditions are known. In this work, we use a dynamical system approach to find the full parameter space of the massive version of each model. In particular, we found that the inclusion of the mass term increases the length of the inflationary period. Additionally, the mass term implies new behaviors for the equation of state of dark energy allowing to distinguish this from other prototypical models of accelerated expansion. We show that an axially symmetric gauge field can support an anisotropic accelerated expansion within the observational bounds.

description: We summarize and analyze the available observational data on the progenitor and the enviroment of V838 Mon. From the available photometric data for the progenitor of V838 Mon we exclude the possibility that the object before eruption was an evolved red giant star (AGB or RGB star). We find that most likely it was a main sequence or pre-main sequence star of ~ 5-10 M_sun. From the light echo structure and evolution we conclude that the reflecting dust is of interstellar nature rather than blown by V838 Mon in the past. We discuss the IRAS and CO data for interstellar medium observed near the position of V838 Mon. Several interstellar molecular regions have radial velocities similar to that of V838 Mon, so dust seen in the light echo might be related to one of them.

description: Using Australian quarterly data from the post-float period 1984:1-2003:1 and a partial system, we identify and estimate two cointegrating relations, one for the interest-rate differential and the other for the nominal exchange rate. Our estimate of the long-run elasticity of the exchange rate with respect to commodity prices is 0.939, which strongly supports the widely held view that the floating Australian dollar is a ‘commodity currency’. We also find that the PPP and UIP cannot be rejected so long as commodity prices are included in the cointegrating relations. Our model outperforms the random walk model in forecasting the exchange rate in the medium run.

Theoretical analysis that allows to calculate explicitly the steady-state dynamic properties of single molecules, such as mean velocity $V$ and dispersion $D$, is presented for N=1 and N=2 models. For the systems with $N>2$ exact analytic expressions for the large-time dynamic properties are obtained in the limit of strong coupling between the lattices that leads to dynamic equilibrium between two parallel kinetic pathways.

Production of Body Knowledge in Mimetic Processes

Year: 2017

description: To a great extent, cultural learning is mimetic learning, which is at the center of many processes of education, self-education, and human development. It is directed towards other people, social communities and cultural heritages and ensures that they are kept alive. Mimetic learning is a sensory, body-based form of learning in which images, schemas and movements needed to perform actions are learned. This embodiment is responsible for the lasting effects that play an important role in all social and cultural fields. A mimetic process creates both similarities and differences to the situations or persons to which or whom they relate. By participating in the living practices of other people, humans expand their own life-worlds and create for themselves new ways of experiencing and acting. Receptivity and activity overlap. In all areas of human existence rituals and gestures are important for the mimetic development of body knowledge. Embodied knowledge is indispensable in religion, politics, economy, science, families, and education. It helps us to deal with difference and alterity and to create a sense of community and social relationships (Wulf 2016). It also enables us to assign meaning and structure to human relations. Ritual knowledge facilitates both continuity and change, as well as experiences of transition and transcendence.

Neutrino Masses Without Seesaw Mechanism in a SUSY SU(5) Model With Additional $\bar{5}'_L+5'_L$
Creators: name: Koide, Yoshio
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: A radiatively-induced neutrino mass matrix with a simple structure is proposed on the basis of an SU(5) SUSY GUT model with R-parity violation. The model has matter fields $\bar{5}'_{L}+5'_{L}$ in addition to the ordinary matter fields $\bar{5}_{L}+10_{L}$ and Higgs fields $H_u+\bar{H}_d$. The R-parity violating terms are given by $\bar{5}_{L} \bar{5}_{L} 10_{L}$, while the Yukawa interactions are given by $\bar{H}_d \bar{5}'_{L} 10_{L}$. Since the matter fields $\bar{5}'_L$ and $\bar{5}_L$ are different from each other at the unification scale, the R-parity violation effects at a low energy scale appear only through the $\bar{5}'_L \leftrightarrow \bar{5}_{L}$ mixings. In order to make this R-parity violation effect harmless for proton decay, a discrete symmetry Z_3 and a triplet-doublet splitting mechanism analogous to the Higgs sector are assumed.

description: Detrended fluctuation analysis (DFA) and detrended moving average (DMA) are two scaling analysis methods designed to quantify correlations in noisy non-stationary signals. We systematically study the performance of different variants of the DMA method when applied to artificially generated long-range power-law correlated signals with an {\it a-priori} known scaling exponent $α_{0}$ and compare them with the DFA method. We find that the scaling results obtained from different variants of the DMA method strongly depend on the type of the moving average filter. Further, we investigate the optimal scaling regime where the DFA and DMA methods accurately quantify the scaling exponent $α_{0}$, and how this regime depends on the correlations in the signal. Finally, we develop a three-dimensional representation to determine how the stability of the scaling curves obtained from the DFA and DMA methods depends on the scale of analysis, the order of detrending, and the order of the moving average we use, as well as on the type of correlations in the signal.

The jet structure and the intrinsic luminosity function of short gamma-ray bursts
Creators: name: Tan, Wei-Wei

Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The joint observation of GW170817 and GRB 170817A indicated that short gamma-ray bursts (SGRBs) can originate from binary neutron star mergers. Moreover, some SGRBs could be detected off-axis, while the SGRB jets are highly structured. Then, by assuming an universal angular distribution of the jet emission for all SGRBs, we re-produce the flux and redshift distributions of the cosmological SGRBs detected by {\it Swift} and {\it Fermi}. For self-consistency, this angular distribution is simultaneously constrained by the luminosity and event rate of GRB 170817A. As a result, it is found that the universal jet structure of SGRBs could approximately have a two-Gaussian profile. Meanwhile, the intrinsic luminosity function (LF) of the on-axis emission of the jets can be simply described by a single power law with a low-luminosity exponential cutoff. The usually discovered broken-power-law apparent LF for relatively high luminosities can naturally result from the coupling of the intrinsic LF with the angular distribution of the jet emission, as the viewing angles to the SGRBs are arbitrarily distributed.

description: The realization of both p-type and n-type operations in a single organic field effect transistor (OFET) is critical for simplifying the design of complex organic circuits. Typically, only p-type or n-type operation is realized in an OFET, while the respective counterpart is either suppressed by charge trapping or limited by the injection barrier with the electrodes. Here we show that only the presence of a top dielectric turns an n-type polymer semiconductor (N2200, Polyera ActiveInk) into an ambipolar one, as detected from both bottom and top gated OFET operation. The effect is independent of the channel thickness and the top dielectric combinations. Variable temperature transfer characteristics show that both the electrons and holes can be equally transported through the bulk of the polymer semiconductor.

Through the Flat Canvas: The Motor Meaning of Realistic Paintings

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2016

description: It is well known that common objects in the environment can evoke possibilities of action, but what about their bi-dimensional representation? Do pictures or paintings that represent action-related objects evoke the same possibilities of actions of the objects that they represent? In contemporary cognitive science, there are two contrasting views on this issue. On the one hand, the ecological-dispositional approach to perception supports the idea that viewing depicted objects as endowed with the potential for action is nothing but an illusion. On the other hand, recent findings show that our motor system is activated by the perception of both real and depicted action-related objects, and this activation plays a functional role in planning motor acts. A broad analysis reveals that the activation of the motor system during perceptual tasks plays a crucial rule in processing the practical meaning of the concrete objects and of the abstract representations of them. This evidence has consequences to our understanding of the way we experience pictures and paintings.

description: We discuss optical associations, spectral energy distributions and photometric redshifts for SWIRE sources in the ELAIS-N1 area and the Lockman Validation Field. The band-merged IRAC (3.6, 4.5, 5.8 and 8.0 mu) and MIPS (24, 70, 160 mu) data have been associated with optical UgriZ data from the INT Wide Field Survey in ELAIS-N1, and with our own optical Ugri data in Lockman-VF. The spectral energy distributions of selected ELAIS sources in N1 detected by SWIRE, most with spectroscopic redshifts, are modelled in terms of a simple set of galaxy and quasar templates in the optical and near infrared, and with a set of dust emission templates (cirrus, M82 starburst, Arp 220 starburst, and AGN dust torus) in the mid infrared. The optical data, together with the IRAC 3.6 and 4.5 mu data, have been used to determine photometric redshifts. For galaxies with known spectroscopic redshifts there is a notable improvement in the photometric redshift when the IRAC data are used, with a reduction in the rms scatter from 10% in (1+z) to 7%. The photometric redshifts are used to derive the 3.6 and 24 mu redshift distribution and to compare this with the predictions of models. For those sources with a clear mid infrared excess, relative to the galaxy starlight model used for the optical and near infrared, the mid and far infrared data are modelled in terms of the same dust emission templates. The proportions found of each template type are: cirrus 31%, M82 29%, Arp 220 10%, AGN dust tori 29%. The distribution of the different infrared sed types in the L_{ir}/L_{opt} versus L_{ir} plane, where L_{ir} and L_{opt} are the infrared and optical bolometric luminosities, is discussed.

description: A percolation transition in the vortex state of a superconducting 2H-NbSe2 crystal is observed in the regime where vortices form a heterogeneous phase consisting of ordered and disordered domains. The transition is signaled by a sharp increase in critical current that occurs when the volume fraction of disordered domains, obtained from pulsed measurements of the current-voltage characteristics, reaches the value Pc= 0.26. Measurements on different vortex states show that while the temperature of the transition depends on history and measurement speed, the value of Pc and the critical exponent characterizing the approach to it, r =1.97 $\pm$ 0.66, are universal.

description: The recognition of human actions in video streams is a challenging task in computer vision, with cardinal applications in e.g. brain-computer interface and surveillance. Deep learning has shown remarkable results recently, but can be found hard to use in practice, as its training requires large datasets and special purpose, energy-consuming hardware. In this work, we propose a scalable photonic neuro-inspired architecture based on the reservoir computing paradigm, capable of recognising video-based human actions with state-of-the-art accuracy. Our experimental optical setup comprises off-the-shelf components, and implements a large parallel recurrent neural network that is easy to train and can be scaled up to hundreds of thousands of nodes. This work paves the way towards simply reconfigurable and energy-efficient photonic information processing systems for real-time video processing.

description: We present a tight-binding based GW approach for the calculation of quasiparticle energy levels in confined systems such as molecules. Key quantities in the GW formalism like the microscopic dielectric function or the screened Coulomb interaction are expressed in a minimal basis of spherically averaged atomic orbitals. All necessary integrals are either precalculated or approximated without resorting to empirical data. The method is validated against first principles results for benzene and anthracene, where good agreement is found for levels close to the frontier orbitals. Further, the size dependence of the quasiparticle gap is studied for conformers of the polyacenes ($C_{4n+2}H_{2n+4}$) up to n = 30.

The Quest for “Authenticity”. Three performances of a Bach’s fugue compared

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2016

description: This paper is meant as a contribution to the general issue of authenticity in musical performances, an issue often debated at a rarefied, speculative level, by introducing a comparison between three case studies consisting of the performative choices in three renown recordings of performances of Bach’s Fugue BWV 1000: two on the classical guitar (Andrés Segovia and Julian Bream) and one on the lute (Hopkinson Smith). This approach allows us to pursue in greater detail the tacit aesthetic and ontological underpinnings of such options. Finally, I use the conceptual apparatus gathered to argue that, generally 1) there are no good reasons to believe that a “historicist” approach, per se, will add aesthetic value to a performance and, in particular 2) it is perfectly adequate to use the modern classical guitar in performing Bach’s works.

description: We study the one loop effective potential for the radion superfield in the supersymmetric Randall-Sundrum scenario with detuned brane tensions. At the classical level the distance between the branes is stabilized while the VEV of the fifth component of the graviphoton is a flat direction which breaks supersymmetry. At the quantum level a potential is generated. This leads to a toy model of a supersymmetric compactification with all the moduli stabilized perturbatively.

description: Neutron diffraction and magnetic susceptibility studies show that orthorhombic single-crystals of topological semimetals ${\rm Sr(Mn_{0.9}Cu_{0.1})Sb_2}$ and ${\rm Sr(Mn_{0.9}Zn_{0.1})Sb_2}$ undergo three dimensional C-type antiferromagnetic (AFM) ordering of the Mn$^{2+}$ moments at $T_N = 200\pm10$ and $210\pm12$ K, respectively, significantly lower than that of the parent SrMnSb$_2$ with $T_N=297 \pm 3$ K. Magnetization versus applied magnetic field (perpendicular to MnSb planes) below $T_N$ exhibits slightly modified de Haas van Alphen oscillations for the Zn-doped crystal as compared to that of the parent compound. By contrast, the Cu-doped system does not show de Haas van Alphen magnetic oscillations, suggesting that either Cu substitution for Mn changes the electronic structure of the parent compound substantially, or that the Cu sites are strong scatterers of carriers that significantly shorten their mean free path thus diminishing the oscillations. Density functional theory (DFT) calculations including spin-orbit coupling predict the C-type AFM state for the parent, Cu-, and Zn-doped systems and identify the $a$-axis (i.e., perpendicular to the Mn layer) as the easy magnetization direction in the parent and 12.5% of Cu or Zn substitutions. In contrast, 25% of Cu content changes the easy magnetization to the $b$-axis (i.e., within the Mn layer). We find that the incorporation of Cu and Zn in SrMnSb$_2$ tunes electronic bands near the Fermi level resulting in different band topology and semi-metallicity. The parent and Zn-doped systems have coexistence of electron and hole pockets with opened Dirac cone around the Y-point whereas the Cu-doped system has dominant hole pockets around the Fermi level with a distorted Dirac cone. The tunable electronic structure may point out possibilities of rationalizing the experimentally observed de Haas van Alphen magnetic oscillations.

Clement Greenberg e la Halakah del Modernismo

description: The understanding of the meaning of Jewish identity in Clement Greenberg's work follows the deep relationship between the conception of Modernism and the interpretation of Franz Kafka's short story The Great Wall of China. Greenberg, whose role as one of the first american popularizers of Kafka's narratives has been relevant, ascribes to the bohemian author an halachic reasoning closely related to his jewish origins. This strictly firm and normative mindset finds resemblances in Greenberg's modernist theory and critical practice, which, according to Susan Noyes-Platt's study, could be interpreted as a derivation, in many aspects, of his Jewish origins and, particularly, as the critic's need to preserve his intellectual thinking from the nazi-fascist advance. Moreover, the article proposes to interpret Greenberg's purism as a form of messianism, that is a faith in a future, but indefinitely belated, absolute purification of the medium.

Dynamical field theory for glass-forming liquids, self-consistent resummations and time-reversal symmetry

description: We analyse the symmetries and the self-consistent perturbative approaches of dynamical field theories for glassforming liquids. In particular, we focus on the time-reversal symmetry (TRS), which is crucial to obtain fluctuation-dissipation relations (FDRs). Previous field theoretical treatment violated this symmetry, whereas others pointed out that constructing symmetry preserving perturbation theories is a crucial and open issue. In this work we solve this problem and then apply our results to the mode-coupling theory of the glass transition (MCT). We show that in the context of dynamical field theories for glass-forming liquids TRS is expressed as a nonlinear field transformation that leaves the action invariant. Because of this nonlinearity, standard perturbation theories generically do not preserve TRS and in particular FDRs. We show how one can cure this problem and set up symmetry-preserving perturbation theories by introducing some auxiliary fields. As an outcome we obtain Schwinger-Dyson dynamical equations that automatically preserve FDRs and that serve as a basis for carrying out symmetry-preserving approximations. We apply our results to MCT, revisiting previous field theory derivations of MCT equations and showing that they generically violate FDR. We obtain symmetry-preserving mode-coupling equations and discuss their advantages and drawbacks. Furthermore, we show, contrary to previous works, that the structure of the dynamic equations is such that the ideal glass transition is not cut off at any finite order of perturbation theory, even in the presence of coupling between current and density. The opposite results found in previous field theoretical works, such as the ones based on nonlinear fluctuating hydrodynamics, were only due to an incorrect treatment of TRS.

Mimicry, Ekphrasis, Construction. «Reading» in Freudian Psychoanalysis
Creators: name: Klammer, Markus
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2016

description: The essay explores the concept of interpretation in Freudian psychoanalysis as an act of reading. Freud understands the appearance of dreams and unconscious phantasies in analogy to the structure of perceptual images. On the one hand, he conceives of the patients’ verbal accounts of those images as a specific kind of ekphrasis. On the other hand, the images themselves are regarded as distorted versions of an underlying »dream text« rendering the fundamental desire that the images express and conceal at the same time. The essay shows that the complex system of translations between different layers of text and image in Freud is based on the assumption that the dream images themselves can be analyzed as texts only mimicking the »natural« appearance of perceptions. Freud’s notion of the »rebus« is central to this discussion. The final part examines Freud’s reading of Michelangelo’s Moses statue in the church San Pietro in Vincoli in Rome. It demonstrates how the Freudian method of interpretation itself reduces the sculpture to a set of signs, making it perform a mimicry of textual systems.

Disturbance Decoupling for Gradient-based Multi-Agent Learning with Quadratic Costs

description: Motivated by applications of multi-agent learning in noisy environments, this paper studies the robustness of gradient-based learning dynamics with respect to disturbances. While disturbances injected along a coordinate corresponding to any individual player's actions can always affect the overall learning dynamics, a subset of players can be disturbance decoupled---i.e., such players' actions are completely unaffected by the injected disturbance. We provide necessary and sufficient conditions to guarantee this property for games with quadratic cost functions, which encompass quadratic one-shot continuous games, finite-horizon linear quadratic (LQ) dynamic games, and bilinear games. Specifically, disturbance decoupling is characterized by both algebraic and graph-theoretic conditions on the learning dynamics, the latter is obtained by constructing a game graph based on gradients of players' costs. For LQ games, we show that disturbance decoupling imposes constraints on the controllable and unobservable subspaces of players. For two player bilinear games, we show that disturbance decoupling within a player's action coordinates imposes constraints on the payoff matrices. Illustrative numerical examples are provided.
