description: New types of relationships between Feynman integrals are presented. It is shown that Feynman integrals satisfy functional equations connecting integrals with different values of scalar invariants and masses. A method is proposed for obtaining such relations. The derivation of functional equations for one-loop propagator- and vertex - type integrals is given. It is shown that a propagator - type integral can be written as a sum of two integrals with modified scalar invariants and one propagator massless. The vertex - type integral can be written as a sum over vertex integrals with all but one propagator massless and one external momenta squared equal to zero. It is demonstrated that the functional equations can be used for the analytic continuation of Feynman integrals to different kinematic domains.

description: We propose and demonstrate a novel method to generate a large-amplitude coherent-state superposition (CSS) via ancilla-assisted photon-subtraction. The ancillary mode induces quantum interference of indistinguishable processes, widening the controllability of quantum superposition at the conditional output. We demonstrate the concept in the time domain, by a simple time-separated two-photon subtraction from cw squeezed light. We observe the largest CSS ever reported without any corrections, which will enable various quantum information applications with CSS states.

description: Image captioning models have lately shown impressive results when applied to standard datasets. Switching to real-life scenarios, however, constitutes a challenge due to the larger variety of visual concepts which are not covered in existing training sets. For this reason, novel object captioning (NOC) has recently emerged as a paradigm to test captioning models on objects which are unseen during the training phase. In this paper, we present a novel approach for NOC that learns to select the most relevant objects of an image, regardless of their adherence to the training set, and to constrain the generative process of a language model accordingly. Our architecture is fully-attentive and end-to-end trainable, also when incorporating constraints. We perform experiments on the held-out COCO dataset, where we demonstrate improvements over the state of the art, both in terms of adaptability to novel objects and caption quality.

description: In this paper we present a method for the estimation of leaks in non-invasive ventilation. Accurate estimation of leaks is a key component of a ventilator, since it determines the ventilator performance in terms of patient-ventilator synchrony and air volume delivery. In particular, in non-invasive ventilation, the patient flow is significantly different from the flow measured at the ventilator outlet. This is mostly due to the vent orifice along the tube that is used for exhalation, but also to the non-intentional leaks that occur elsewhere in the circuit (e.g., at the mask). Such leaks are traditionally quantified via a model with two parameters, but only one of them is continually updated - the other is fixed. The new algorithm allows for breath-by-breath update of both parameters. This was made possible by leveraging a model describing the patient respiratory mechanics.

title: International Exhibitions in Venice
Creators: name: Lamberti, Maria Mimita
Publisher: name: OBOE JOURNAL
Year: 2020

description: "International Exhibitions in Venice" was written by Maria Mimita Lamberti in 1982 as part of a larger text "1870-1915: i mutamenti del mercato e le ricerche degli artisti" printed in Einaudi’s encyclopedic publication Storia dell'arte italiana. The text focuses its attention on the changes that occurred both in the art market system and in artistic expression between 1870 and 1915. Inserted in a companion volume on Italian twentieth-century art, it was intended to provide an understanding of the growing apparatus of exhibitions. The text’s precise use of archival documents combined with its original methodology has ensured that this excerpt continues to be used as a reference for those who study the Venice Biennale. Moreover, Lamberti approaches the Venice Biennale from multiple perspectives, highlighting the important fact that the Biennale is the result of many intercepting actors and forces in its history.

A session of transcutaneous electrical nerve stimulation changes the input-output function of motoneurons and alters the sense of force

description: Transcutaneous electrical nerve stimulation (TENS) is commonly used in research and clinical settings for pain management and augmenting somatosensory inputs for motor recovery. Besides its functional effect, TENS acutely alters kinesthesia and force steadiness. However, the short-term impact following a session of TENS on proprioception and motor unit behavior is unknown. We evaluated the effect of a session of TENS on the senses of force, joint position, touch, and discharge activity of motor units. Fifteen healthy participants underwent two experiments, each with two visits randomly administering TENS or sham-TENS. The sense of force (Exp. 1) and position (Exp. 2) were evaluated through matching trials by pinching a dial and rotating their wrist (ulnar deviation). Isometric pinch contractions were performed before and after the session of TENS or sham-TENS, in which electromyographic signals were recorded from the first dorsal interosseus (FDI) and abductor pollicis brevis (APB). Results showed that TENS acutely altered the senses of force, position, and touch, but only the sense of force remained altered following TENS. Motor unit discharge rates increased in both FDI and APB muscles for the same force output following TENS. A positive correlation was also observed between motor unit discharge rates and errors in force perception. These findings suggest that a session of TENS may have short-term effects on the input/output function of motoneurons (5 - 10 min in this study), which in turn may alter the sense of force. However, the precise timeline for these short-term aftereffects is unknown.

title: The Magazine "la biennale": Articulating a Model for the Periodical Publication of a Recurring Exhibition
Creators: name: Salvaneschi, Camilla
Publisher: name: OBOE JOURNAL
Year: 2020

description: The first biennial that published a magazine was the Venice Biennale. The magazine la biennale di Venezia was published from 1950 to 1971. It was conceived as an institutional instrument, to keep the audience of the show informed about the activities of the Biennial during the year. The magazine had the mission to engage in the activities organized by the institution, and discuss and examine all the disciplines at the core of the Biennials program, which meant not only art, but also cinema, fashion, music and theatre. The magazine la biennale pursued the same international intents as the exhibition, becoming a site of network and exchange between different nations, as well as a medium to foster local and international critical dialogue. During the almost twenty years of its existence the publication evolved from informative instrument, which included lists of artworks sold during the editions of the biennial, alongside lists of new acquisitions of the biennial’s archive, into a container for critical thought and theory.

description: Let $\mathcal{A}=(A_{1},...,A_{n},...)$ be a finite or infinite sequence of $2\times2$ matrices with entries in an integral domain. We show that, except for a very special case, $\mathcal{A}$ is (simultaneously) triangularizable if and only if all pairs $(A_{j},A_{k})$ are triangularizable, for $1\leq j,k\leq\infty$. We also provide a simple numerical criterion for triangularization. Using constructive methods in invariant theory, we define a map (with the minimal number of invariants) that distinguishes simultaneous similarity classes for non-commutative sequences over a field of characteristic $\neq2$. We also describe canonical forms for sequences of $2\times2$ matrices over algebraically closed fields, and give a method for finding sequences with a given set of invariants.

description: We study the dynamical status of the poor, low X-ray luminous galaxy clusters Abell 610, Abell 725, and Abell 796 (at z=0.1, 0.09, and 0.16, respectively), containing diffuse radio sources (relic, relic, and possible halo, respectively). Our analysis is based on new spectroscopic data obtained at the William Herschel Telescope for 158 galaxies, new photometry obtained at the Isaac Newton Telescope with the addition of data recovered from the Data Release 5 of the Sloan Digital Sky Survey. We use statistical tools to select 57, 36, and 26 cluster members and to analyze the kinematics of cluster galaxies, as well as to study the 2D cluster structure. The low values we compute for the global line-of-sight velocity dispersion of galaxies (420-700 km/s) confirm that these clusters are low-mass clusters. Abell 610 shows a lot of evidence of substructure. It seems to be formed by two structures separated by about 700 km/s in the cluster rest-frame, having comparable velocity dispersion (about 200 km/s) and likely causing a velocity gradient. The analysis of the 2D galaxy distribution shows a bimodal distribution in the core elongated in the SE-NW direction. Abell 725 and Abell 796, which are less sampled, show marginal evidence of substructure in the velocity space. They are elongated in the 2D galaxy distribution. For both Abell 610 and Abell 725 we shortly discuss the possible connection with the hosted diffuse radio relic. Our results show that relic radio sources are likely connected with merger events,but are not limited to massive clusters. About the possible halo source in Abell 796, there is some evidence of a merger event in this non-massive cluster, but a pointed radio observation is necessary to confirm this halo.

description: The issue of how superconductivity originate in the $CuO_2$ planes believed to be crucial to understanding the high $T_c$ superconducting cuprates is still an going debate. In the wake of recent experimental observations of the the Zhang-Rice singlet (ZRS), its formation and propagation need to be revisited especially by using a simple approach almost at a phenomenological level. Within a highly simplified correlated variational approach (HSCVA) in this paper, a new formation of the ZRS as constituting the ground state of a single-band t-J model of the $CuO_2$ planes is developed. This formation is then used to demonstrate how the ZRS can be propagated as a probable Cooper channel in the $CuO_2$ planes.

title: How La Biennale as a Brand was Born. Venice as the Archetype of a Biennial City
Creators: name: Martini, Vittoria
Publisher: name: OBOE JOURNAL
Year: 2020

description: “When discussing the Biennale, it is impossible to ignore the particular importance of Venice as its host city”. The history of the bond between Venice and the Venice Biennale has become an archetype for all those cities that, from the end of the 1980s, took part in the so-called ‘biennialization,’ namely the explosion of the phenomenon of biennials all over the world. Historically, the image of a decadent Venice was used as a means of regenerating the city and bringing it into the modern world. Its poetic qualities contained a universalism which opened the city up for international consumption. This appealed to universal myth and its appropriation for commercial purposes underlay the development of the early Biennale. The history, beauty and architectural singularity of Venice – which were born out of political and economic necessity – became the distinguishing attributes of the “Patrimony of Venice.” Despite the Venice Biennale has never changed its structure, mirroring a lost modern world with its national pavilions, it survived until the post-globalized world remaining at the centre of the art world, the place where the national/local identities still have a voice. The “Patrimony of Venice” is at the core of its success and Venice and its Biennale could be seen today as the archetype of a “brand” thanks to the specificity it preserved. In this text I will analyse the history of the bond between the city of Venice and the Venice Biennale to outline the reasons of a successful “brand”.

Multivariate spacings based on data depth: I. Construction of nonparametric multivariate tolerance regions

description: This paper introduces and studies multivariate spacings. The spacings are developed using the order statistics derived from data depth. Specifically, the spacing between two consecutive order statistics is the region which bridges the two order statistics, in the sense that the region contains all the points whose depth values fall between the depth values of the two consecutive order statistics. These multivariate spacings can be viewed as a data-driven realization of the so-called ``statistically equivalent blocks.'' These spacings assume a form of center-outward layers of ``shells'' (``rings'' in the two-dimensional case), where the shapes of the shells follow closely the underlying probabilistic geometry. The properties and applications of these spacings are studied. In particular, the spacings are used to construct tolerance regions. The construction of tolerance regions is nonparametric and completely data driven, and the resulting tolerance region reflects the true geometry of the underlying distribution. This is different from most existing approaches which require that the shape of the tolerance region be specified in advance. The proposed tolerance regions are shown to meet the prescribed specifications, in terms of $β$-content and $β$-expectation. They are also asymptotically minimal under elliptical distributions. Finally, a simulation and comparison study on the proposed tolerance regions is presented.

Nonclassicality of states and measurements by breaking classical bounds on statistics

Year: 2008
Subjects: subject: Quantum Physics (quant-ph)

description: We derive exceedingly simple practical procedures revealing the quantum nature of states and measurements by the violation of classical upper bounds on the statistics of arbitrary measurements. Data analysis is minimum and definite conclusions are obtained without evaluation of moments, or any other more sophisticated procedures. These nonclassical tests are independent of other typical quantum signatures such as sub-Poissonian statistics, quadrature squeezing, or oscillatory statistics. This approach can be equally well applied to very diverse situations such as single- and two-mode fields, observables with continuous and discrete spectra, finite- and infinite-dimensional systems, and ideal and noisy measurements.

Oblique swimming in characoid fishes with special reference to the genus Nannostomus Gunther 1872
Creators: name: Chondoma, Emmanuel C.
Publisher: name: University of British Columbia
Year: 2010

description: The hydrodynamics and mechanics of obliquely swimming characoid species Chilodus punetatus, Nannostomus eques, Nannostomus unifasciatus, Thayeria. boehlkei and Thayeria obliqua are investigated. In Chilodus punctatug, Nannostomus eques and Nannostomus unifasciatus the position of the centre of mass relative to the centre of buoyancy is the reverse of what would be expected from their pitch. The centre of mass is in front of the centre of buoyancy in the two Nannostomus species which swim with a positive pitch and vice versa in Chilodus punctatus which swims with negative pitch. The relative positions of these two centres are in such a way that they help to bring the fish horizontal during fast swimming. Pitch in these species is maintained by the action of the pectoral and caudal fins. In the two Thayeria species the centre of mass is behind the centre of buoyancy and their separation is responsible for the positive pitch. The fins are used to correct for this pitch to the desirable level. The enlarged lower lobe of the caudal fin in Nannostomus species has an epibatic effect and does not contribute to the forces responsible for the pitch in hovering as previously proposed. Relative vertebrae size in Nannostomus eques and Nannostomus unifasciatus when compared to Nannostomus becfordi and Nannostomus trifasciatus which swim horizontally show adaptations towards a strategy of rapid start from rest.

In the first layer, we find a domain-wall phase and a (7/16) registered structure between the commensurate (1/3) and the incommensurate solid phases. For the second layer, we find only superfluid and incommensurate solid phases. The commensurate phase found in previous simulation work is only observed if first layer particles are kept fixed; it disappears upon explicitly including their zero-point fluctuations. No evidence of any "supersolid" phase is found.

Year: 2019

Webinar Slides - November 18, 2019, Dr. Santiago Segarra
This webinar will address the problem of identifying the structure of an undirected graph from the observation of signals defined on its nodes. Fundamentally, the unknown graph encodes direct relationships between signal elements, which we aim to recover from observable indirect relationships generated by a diffusion process on the graph. Our approach leverages concepts from convex optimization and stationarity of graph signals, in order to identify the graph shift operator (a matrix representation of the graph) given only its eigenvectors. These spectral templates can be obtained, e.g., from the sample covariance of independent graph signals diffused on the sought network. The novel idea is to find a graph shift that, while being consistent with the provided spectral information, endows the network with certain desired properties such as sparsity. To that end, we develop efficient inference algorithms stemming from provably tight convex relaxations of natural non-convex criteria.

The effect of late giant collisions on the atmospheres of protoplanets and the formation of cold sub-Saturns

description: We investigate the origins of cold sub-Saturns (CSS), an exoplanetary population inferred from microlensing surveys. If confirmed, these planets would rebut a theorised gap in planets' mass distribution between those of Neptune and Jupiter caused by the rapid runaway accretion of super-critical cores. In an attempt to resolve this theoretical-observational disparity, we examine the outcomes of giant collisions between sub-critical protoplanets. Due to the secular interaction among protoplanets, these events may occur in rapidly depleting discs. We show that impactors ~ 5% the mass of near-runaway envelopes around massive cores can efficiently remove these envelopes entirely via a thermally-driven super-Eddington wind emanating from the core itself, in contrast with the stellar Parker winds usually considered. After a brief cooling phase, the merged cores resume accretion. But, the evolution timescale of transitional discs is too brief for the cores to acquire sufficiently massive envelopes to undergo runaway accretion despite their large combined masses. Consequently, these events lead to the emergence of CSS without their transformation into gas giants. We show that these results are robust for a wide range of disc densities, grain opacities and silicate abundance in the envelope. Our fiducial case reproduces CSS with heavy (>= 30 M_Earth) cores and less massive (a few M_Earth) sub-critical envelopes. We also investigate the other limiting cases, where continuous mergers of comparable-mass cores yield CSS with wider ranges of core-to-envelope mass ratios and envelope opacities. Our results indicate that it is possible for CSS and Uranus and Neptune to emerge within the framework of well studied processes and they may be more common than previously postulated.

description: We study photon diffusion in a two-dimensional random packing of monodisperse disks as a simple model of granular media and wet foams. We assume that the intensity reflectance of disks is a constant. We present an analytic expression for the transport-mean-free path in terms of the velocity of light in the disks and host medium, radius and packing fraction of the disks, and the intensity reflectance. For the glass beads immersed in the air or water, we estimate transport-mean-free paths about half the experimental ones. For the air bubbles immersed in the water, transport-mean-free paths is an inverse function of liquid volume fraction of the model wet foam. This throws new light on the empirical law of Vera et. al, and promotes more realistic models.

title: Flipping the Exhibition Inside Out: Enrico Crispolti’s Show Ambiente come Sociale at the 1976 Venice Biennale
Creators: name: Tanga, Martina
Publisher: name: OBOE JOURNAL
Year: 2020

description: In 1976, art historian and curator Enrico Crispolti—charged with organizing the show, Ambiente come Sociale, for the Italian Pavilion at the Venice Biennale—radically rethought the exhibition form. In an unconventional move, he strategically chose not to house any artworks within the confines of the gallery space. Instead, he sprawled documentary photographs, videos, texts, pamphlets, and audio recordings on tables like the products of field research. The artworks themselves were site-specific and located elsewhere in various towns and cities across the country. Adhering to the Biennale’s overarching theme of environment and decentralization, Crispolti championed artists working in Arte Ambientale (environmental art), who were making art located in the urban context and social reality. Yet, Crispolti turned the institution’s theme inside out: while visitors came to its center to see the art, they were thrust outwards towards the peripheries, and outside the city, where the actual artworks were sited. The ingenuity of this action, and the re-conception of what could constitute installation art, is evident when Crispolti’s exhibition is compared to Germano Celant’s 1976 Biennale show Ambiente / Arte, a diachronic art historical study of this new art medium. While Celant presented self-referential examples based on formal qualities, Crispolti exponentially broadened the boundaries of installation art to include the environment, urban context, social questions, and political contingency. This paper examines Crispolti’s curatorial strategy as it aligned, but also critiqued, the Biennale as a cultural institution. Furthermore, it frames the exhibition as a medium for artistic innovation, particularly in the definition of environment and installation art.

The rate of secular evolution in elliptical galaxies with central masses

description: We study a series of $N-$body simulations representing elliptical galaxies with central masses. Starting from two different systems with smooth centres, which have initially a triaxial configuration and are in equilibrium, we insert to them central masses of various values. Immediately after such an insertion a system presents a high fraction of particles moving in chaotic orbits, a fact causing a secular evolution towards a new equilibrium state. The chaotic orbits responsible for the secular evolution are identified. Their typical Lypaunov exponents are found to scale with the central mass as a power law $L\propto m^s$ with $s$ close to 1/2. The requirements for an effective secular evolution within a Hubble time are examined. These requirements are quantified by introducing a quantity called \emph{effective chaotic momentum} $\mathscr{L}$. This quantity is found to correlate well with the rate of the systems' secular evolution. In particular, we find that when $\mathscr{L}$ falls below a threshold value (0.004 in our $N-$body units) a system does no longer exhibit significant secular evolution.

description: Soybean is the most globalized, traded and processed crop commodity. USA, Argentina and Brazil continue to be the top three producers and exporters of soybean and soymeal. Indian soyindustry has also made a mark in the national and global arena. While soymeal, soyoil, lecithin and other soy-derivatives stand to be driven up by commerce, the soyfoods for human health and nutrition need to be further promoted. The changing habitat of commerce in soyderivatives necessitates a shift in strategy, technological tools and policy environment to make Indian soybean industry continue to thrive in the new industrial era. Terms of trade for soyfarming and soy-industry could be further improved. Present trends, volatilities, slowdowns, challenges faced and associated desiderata are accordingly spelt out in the present article.

description: While Cadmium Telluride (CdTe) excels in terms of photon radiation absorption properties and outperforms silicon (Si) in this respect, the crystal growth, characterization and processing into a radiation detector is much more complicated. Additionally, large concentrations of extended crystallographic defects, such as grain boundaries, twins, and tellurium (Te) inclusions, vary from crystal to crystal and can reduce the spectroscopic performance of the processed detector. A quality assessment of the material prior to the complex fabrication process is therefore crucial. To locate the Te-defects, we scan the crystals with infrared microscopy (IRM) in different layers, obtaining a 3D view of the defect distribution. This provides us with important information on the defect density and locations of Te inclusions, and thus a handle to assess the quality of the material. For the classification of defects in the large amount of IRM image data, a convolutional neural network is employed. From the post-processed and analysed IRM data, 3D defect maps of the CdTe crystals are created, which make different patterns of defect agglomerations inside the crystals visible. In total, more than 100 crystals were scanned with the current IRM setup. In this paper, we compare two crystal batches, each consisting of 12 samples. We find significant differences in the defect distributions of the crystals.

Volumen 15: Numero 4: Controladores de Microrredes: El Corazon y el Alma de la Automatizacion de Microrredes
Nuestra edición de controladores de microrredes analiza varias aplicaciones de estas tecnologías avanzadas de última generación. Los controladores deben prestar servicio de manera flexible a las cargas críticas en una amplia variedad de condiciones operativas, incluida la transferencia de potencia desde y hacia el servicio público interconectado y el funcionamiento autosuficiente en modo aislado. Los sistemas de detección y aislamiento de fallas deben poseer la habilidad de funcionar bajo una amplia gama de la disponibilidad ante cortocircuitos y condiciones de flujo de potencia. El estado de la microrred puede ser altamente variable debido a los cambios en la configuración de condiciones forzadas y de cortes del mantenimiento, diferentes niveles y tasas de cambio de la demanda, y muchos estados de producción de abastecimiento de recursos que normalmente incluyen a la energía fotovoltaica. El funcionamiento físico de la microrred debe respetar también su modelo de negocio mediante la  reducción del costo de operación.

Slides for -Enabling Identity-Based Integrity Auditing and Data Sharing With Sensitive Information Hiding for Secure Cloud Storage

With cloud storage services, users can remotely store their data to the cloud and realize the data sharing with others. Remote data integrity auditing is proposed to guarantee the integrity of the data stored in the cloud. In some common cloud storage systems, such as the electronic health records system, the cloud file might contain some sensitive information that should not be exposed to others when the cloud file is shared. Encrypting the whole shared file can realize the sensitive information hiding, but will make this shared file unusable by others. How to realize data sharing with sensitive information hiding in remote data integrity auditing still had not been explored, that is, up to now.

This webinar, which is based on our original article, addresses this problem and proposes a remote data integrity auditing scheme that realizes data sharing with sensitive information hiding. In our scheme, a sanitizer is used on the data blocks corresponding to the sensitive information of the file and transforms these data blocks? signatures into valid ones for the sanitized file. These signatures are used to verify the integrity of the sanitized file in the integrity auditing phase. As a result, our scheme enables the file stored in the cloud to be shared and used by others on the condition that the sensitive information is hidden, while the remote data integrity auditing is still able to be efficiently executed.

The proposed scheme is based on identity-based cryptography, which simplifies the complicated certificate management. Security analysis and performance evaluation has shown that the proposed scheme is secure and efficient.
