description: The compositional model is often used to describe multicomponent multiphase porous media flows in the petroleum industry. The fully implicit method with strong stability and weak constraints on time-step sizes is commonly used in the mainstream commercial reservoir simulators. In this paper, we develop an efficient multi-stage preconditioner for the fully implicit compositional flow simulation. The method employs an adaptive setup phase to improve the parallel efficiency on GPUs. Furthermore, a multi-color Gauss-Seidel algorithm based on the adjacency matrix is applied in the algebraic multigrid methods for the pressure part. Numerical results demonstrate that the proposed algorithm achieves good parallel speedup while yields the same convergence behavior as the corresponding sequential version.

description: We perform an extensive analysis of neutrino diffusion in quark matter within the MIT bag model at arbitrary temperature and degeneracy. We examine in detail the contribution of each of the relevant weak interaction processes to the total neutrino opacity and evaluate the effect of the strange quark mass, the bag constant, and the QCD perturbative corrections to the MIT bag model. We also investigate the anisotropic contribution to the neutrino distribution function in scatterings, the mean energy transfer and the mean scattering angle. The density and temperature dependence of the diffusion coefficients $D_n$ that govern the cooling and deleptonization of a compact star is shown in detail. Finally, our numerical results for the neutrino mean free paths are compared against known analytic approximations. We conclude that neutrino scattering constitutes a significant portion of the total neutrino opacity in leptonized quark matter and neutrino-quark scattering is, in general, very similar to neutrino-electron scattering with respect to both mean energy transfer per scattering and mean scattering angle.

description: Planning quality assurance (QA) activities in a systematic way and controlling their execution are challenging tasks for companies that develop software or software-intensive systems. Both require estimation capabilities regarding the effectiveness of the applied QA techniques and the defect content of the checked artifacts. Existing approaches for these purposes need extensive measurement data from historical projects. Due to the fact that many companies do not collect enough data for applying these approaches (especially for the early project lifecycle), they typically base their QA planning and controlling solely on expert opinion. This article presents a hybrid method that combines commonly available measurement data and context-specific expert knowledge. To evaluate the method's applicability and usefulness, we conducted a case study in the context of independent verification and validation activities for critical software in the space domain. A hybrid defect content and effectiveness model was developed for the software requirements analysis phase and evaluated with available legacy data. One major result is that the hybrid model provides improved estimation accuracy when compared to applicable models based solely on data. The mean magnitude of relative error (MMRE) determined by cross-validation is 29.6% compared to 76.5% obtained by the most accurate data-based model.

description: È il sottotitolo del recente volume di Alessandro Carrera a precisare l’oggetto sul quale la sua Filosofia del minimalismo intende focalizzarsi: “La musica e il piacere della ripetizione”. Non un trattato sul minimalismo, né un saggio di filosofia o di estetica della musica, ma una riflessione articolata a partire da un tema, quello della ripetizione, certo intrecciato al minimalismo, ma illustrato in maniera originale dai frequenti riferimenti di carattere letterario, sociologico, antropologico e, naturalmente, filosofico.

description: This paper presents PREVENT, an approach for predicting and localizing failures in distributed enterprise applications by combining unsupervised techniques. Software failures can have dramatic consequences in production, and thus predicting and localizing failures is the essential step to activate healing measures that limit the disruptive consequences of failures. At the state of the art, many failures can be predicted from anomalous combinations of system metrics with respect to either rules provided from domain experts or supervised learning models. However, both these approaches limit the effectiveness of current techniques to well understood types of failures that can be either captured with predefined rules or observed while trining supervised models. PREVENT integrates the core ingredients of unsupervised approaches into a novel approach to predict failures and localize failing resources, without either requiring predefined rules or training with observed failures. The results of experimenting with PREVENT on a commercially-compliant distributed cloud system indicate that PREVENT provides more stable and reliable predictions, earlier than or comparably to supervised learning approaches, without requiring long and often impractical training with failures.

description: Preludi ad una metafisica della musica contemporanea, scritto dal compositore David Fontanesi e da poco pubblicato dalla Zecchini, è un breve ma assai intenso testo destinato a far discutere per la radicalità delle posizioni che l’Autore strenuamente difende. Il libro è infatti un vero e proprio atto d’accusa verso una disumanizzazione della musica del Ventesimo secolo, accusa che non di rado prende la forma dell’invettiva, ora veemente ora sarcastica, senza tuttavia che ciò sminuisca l’apparato critico e teoretico. L’Autore supporta i suoi sferzanti giudizi estetici con puntuali analisi delle partiture, che fanno eco a un’indagine di ordine metafisico, volta cioè a enucleare i presupposti concettuali delle teorie compositive che hanno segnato una svolta nella prassi tanto produttiva quanto ricettiva della musica moderna-contemporanea.

A new concordance homomorphism, which is independent of the Rasmussen invariant, plays a central role in these formulae. We also explore whether similar formulae hold for the Ozsváth-Szabó invariant $τ$.

Full-shape BOSS constraints on dark matter interacting with dark radiation and lifting the $S_8$ tension

description: In this work we derive constraints on interacting dark matter-dark radiation models from a full-shape analysis of BOSS-DR12 galaxy clustering data, combined with Planck legacy cosmic microwave background (CMB) and baryon acoustic oscillation (BAO) measurements. We consider a set of models parameterized within the effective theory of structure formation (ETHOS), quantifying the lifting of the $S_8$ tension in view of KiDS weak-lensing results. The most favorable scenarios point to a fraction $f\sim 10-100\%$ of interacting dark matter as well as a dark radiation temperature that is smaller by a factor $ξ\sim 0.1-0.15$ compared to the CMB, leading to a reduction of the tension to the $\sim 1σ$ level. The temperature dependence of the interaction rate favored by relaxing the $S_8$ tension is realized for a weakly coupled unbroken non-Abelian $SU(N)$ gauge interaction in the dark sector. To map our results onto this $SU(N)$ model, we compute higher-order corrections due to Debye screening. We find a lower bound $α_d\equiv g_d^2/(4π)\gtrsim 10^{-8} (10^{-9})$ for dark matter mass $1000 (1)$ GeV for relaxing the $S_8$ tension, consistent with upper bounds from galaxy ellipticities and compatible with self-interactions relevant for small-scale structure formation.

Secular Damping of Stellar Bars in Spinning Dark Matter Halos

description: We demonstrate that growth of stellar bars in spinning dark matter halos is heavily suppressed in the secular phase of evolution, using numerical simulations of isolated galaxies. In a representative set of models, we show that for values of the cosmological spin parameter lambda > 0.03, bar growth (in strength and size) becomes increasingly quenched. Furthermore, slowdown of bar pattern speed weakens substantially with increasing `lambda,' until it ceases completely. The terminal structure of bars is affected as well, including extent and shape of their boxy/peanut bulges. The essence of this effect lies in the modified angular momentum exchange between the disk and the halo facilitated by the bar. For the first time we have demonstrated that a dark matter halo can emit and not purely absorb angular momentum. Although the halo as a whole is not found to emit, the net transfer of angular momentum from the disk to the halo is significantly reduced or completely eliminated. The paradigm shift implies that the accepted view that disks serve as sources of angular momentum and halos serve as sinks, must be revised. Halos with lambda > 0.03 are expected to form a substantial fraction, based on lognormal distribution of lambda. Dependence of secular bar evolution on halo spin, therefore, implies profound corollaries for the cosmological evolution of galactic disks.

L’apostolo della musica. Ritratto di Nadia Boulanger
Creators: name: Menichelli, Caterina
Publisher: name: De Musica

description: Abstract

Nadia Boulanger (1887-1979) fu la musicista e didatta francese che scoprì e formò alcuni fra gli artisti che contribuirono a scrivere la storia della musica del ‘900, da Aaron Copland, Philip Glass, Quincy Jones e Astor Piazzolla, a Elliot Carter, Roy Harris, Virgil Thomson, Jean Francaix e Dinu Lipatti. Cresciuta a Parigi tra laBelle Époque e i ruggenti Anni 20, e dotata di un talento forgiato da anni di studi intensi, osò sfidare, con scelte coraggiose, i più basilari codici di comportamento del suo tempo: visse del proprio lavoro, partecipò a concorsi musicali di solito riservati agli uomini e diresse, prima donna in assoluto, orchestre prestigiose. Rinunciò alla composizione solo alla morte prematura dell’adorata sorella Lili, dedicandosi esclusivamente alla direzione d’orchestra e all’insegnamento. Le celeberrime Wednesday Lessonsche teneva nel suo appartamento di rue Ballu a Parigi, o quelle del Conservatorio Franco-Americano di Fontainebleau, formarono negli anni schiere di musicisti, molti dei quali contribuirono allo sviluppo della tradizione classica nella musica americana. La sezione biografica del presente contributo è seguita da un approfondimento in cui si tracciano le linee guida del metodo educativo e didattico di Nadia Boulanger, ancora oggi fonte di ispirazione.

description: Oysters play a pivotal role in the bay living ecosystem and are considered the living filters for the ocean. In recent years, oyster reefs have undergone major devastation caused by commercial over-harvesting, requiring preservation to maintain ecological balance. The foundation of this preservation is to estimate the oyster density which requires accurate oyster detection. However, systems for accurate oyster detection require large datasets obtaining which is an expensive and labor-intensive task in underwater environments. To this end, we present a novel method to mathematically model oysters and render images of oysters in simulation to boost the detection performance with minimal real data. Utilizing our synthetic data along with real data for oyster detection, we obtain up to 35.1% boost in performance as compared to using only real data with our OysterNet network. We also improve the state-of-the-art by 12.7%. This shows that using underlying geometrical properties of objects can help to enhance recognition task accuracy on limited datasets successfully and we hope more researchers adopt such a strategy for hard-to-obtain datasets.

description: Abstract [ma anche: tastar de corde]

Quasi un secolo fa un uomo piccolo – con gli occhi grandi e straniti – chiede rifugio a una casa con tante stanze.

Assieme a un altro uomo – capace di ascoltare e vedere – iniziano allora un dialogo fatto di visioni e ospitalità. Era il franare del tempo. L’incrinarsi delle immagini. Quelle dentro e quelle fuori. Il non saper più dove mettere le cose. Che nel mondo a volte fa freddo. Quando tutto deve stare per forza come in bilico su una linea ben tirata. Allora si precipita. Giù. O là. Non so bene dove. So che fa paura. E freddo. L’equilibrismo.

Dare un luogo al sub-limo del tempo. A ciò che vi affiora. E tendere corde – anche – da finestra a finestra. E ghirlande da campanile a campanile. E catene – d’oro – da stella a stella. Danzando.

Questo – in fin dei conti – hanno fatto i due uomi. Tutto il tempo.

Questo parlottio ha poi generato Mnemosyne. E un prezioso libro sul pensiero che fugge.

Non ne parlerò di questo, ma tutto – in queste pagine – ne è debitore[1].

Keywords: tempo, policronie, mappe, György Kurtág, Samuel Beckett.

[1] I due uomini sono Aby Warburg e Ludwig Binswanger che nella clinica svizzera di Bellevue hanno provato a ripensare il tempo. E a danzare. Con Rimbaud.

description: Photonic methods of radio-frequency waveform generation and processing provide performance and flexibility over electronic methods due to the ultrawide bandwidth offered by the optical carriers. However, they suffer from lack of integration and slow reconfiguration speed. Here we propose an architecture of integrated photonic RF waveform generation and processing, and implement it on a silicon chip fabricated in a semiconductor manufacturing foundry. Our device can generate programmable RF bursts or continuous waveforms with only the light source, electrical drives/controls and detectors being off chip. It turns on and off an individual pulse in the RF burst within 4 nanoseconds, achieving a reconfiguration speed three orders of magnitude faster than thermal tuning. The on-chip optical delay elements offers an integrated approach to accurately manipulate individual RF waveform features without constrains set by the speed and timing jitter of electronics, and should find broad applications ranging from high-speed wireless to defense electronics.

description: Supersymmetric black holes in AdS spacetime are inherently interesting for the AdS/CFT correspondence. Within a four dimensional gauged supergravity theory coupled to vector multiplets, the only analytic solutions for regular, supersymmetric, static black holes in AdS4 are those in the STU-model due to Cacciatori and Klemm. We study a class of U(1)-gauged supergravity theories coupled to vector multiplets which have a cubic prepotential, the scalar manifold is then a very special Kahler manifold. When the resulting very special Kahler manifold is a homogeneous space, we find analytic solutions for static, supersymmetric AdS4 black holes with vanishing axions. The horizon geometries of our solutions are constant curvature Riemann surfaces of arbitrary genus.

Leggere i poeti. Note in margine a Giovanni Pascoli
Creators: name: Piana, Giovanni
Publisher: name: De Musica
Year: 2018

description: Questo saggio si propone fondamentalmente due compiti: in primo luogo intende mostrare un’inclinazione di lettura della poesia di Giovanni Pascoli che metta in evidenza la necessità di conferire autonomia ad aspetti che, pur essendo stati ormai ampiamente analizzati dalla critica letteraria, spesso si presentano ancora malamente commisti con elementi che rimandano a presupposti di origine strutturalistica e storicistica. Secondo l’inclinazione qui proposta viene soprattutto esaltata la componente immaginativa, stando alle linee tracciate nella poetica del Fanciullino in rapporto alla quale l’autore ritiene di poter cogliere concetti riferibili ad una filosofia dell'immaginazione di impianto fenomenologico. Intraprendendo questa via si fa sempre più avanti un compito ed uno scopo più ampio, che diventa anzi prioritario. Si impongono infatti la domande: quale atteggiamento si deve assumere quando ci si accinge a leggere i poeti? In che modo si può far tesoro della critica letteraria - che offre ausili indispensabili per questa lettura - senza rischiare di compromettere la sostanza immaginativa dell’opera? L’autore tenta di mostrare che, a partire da Pascoli, si possano trarre suggerimenti per una risposta a domande così impegnative.

Il missile e la corda: modelli 'ingenui' nell'acustica degli antichi
Creators: name: Raffa, Massimo
Publisher: name: De Musica

description: L’interesse per i fenomeni sonori, musicali e non, porta il pensiero greco, fin dalle sue fasi più antiche, a costruire modelli che spieghino l’origine del suono, il suo propagarsi e le sue qualità. Tali modelli, dapprima impliciti nel sistema metaforico della lingua greca, poi espliciti nelle diverse elaborazioni teoriche dei pensatori e dei teorici musicali, rivelano più di un tratto di ‘ingenuità’ (nel senso della bozziana ‘fisica ingenua’) e sono sostanzialmente riconducibili ai due archetipi del missile (il suono come oggetto ‘lanciato’ verso un bersaglio a seguito di un impatto tra due corpi) e della corda (il suono come risultato di un movimento periodico che genera una successione di impatti). I due modelli coesistono lungo tutto lo sviluppo del pensiero greco, interagendo con le dottrine delle diverse scuole filosofiche.

Since the earliest stages of their civilisation, the Greeks show a keen interest in sound, both musical and non-musical. They tend to build mental models in order to explain where sound comes from, how it propagates and what gives it its qualities. Such models are at first implied in the metaphors of the Greek language, then are made explicit in the reflections carried out by scientist and music theorists. On the whole, they reveal some streaks of naïveté (in the sense of Paolo Bozzi’s ‘naïve physics’) and can be reduced to two different archetypes: the missile (whereby sound is an object targeted at a specific aim as a result of two bodies colliding with each other) and the string (whereby sound comes as a result of a series of a succession of impacts generated by a periodic movement). These two models coexist throughout the development of Greek thought and interact with the doctrines of the different philosophical schools.

This estimate is analogous to an estimate that Linnik established in his attempt to prove his celebrated theorem concerning the size of the smallest prime number of an arithmetic progression. Our work builds on ideas coming from the pretentious large sieve of Granville, Harper and Soundararajan and it also borrows insights from the treatment of Koukoulopoulos on multiplicative functions with small averages.

description: Recent developments in the engineering of metamaterials have brought forth a myriad of mesmerizing mechanical properties that do not exist in ordinary solids. Among these, twisting metamaterials, acoustical chirality, or Willis coupling are sample-size dependent. The purpose of this work is, first, to examine the mechanical performance of a new twisting cubic metamaterial. Then, we perform a comparative investigation of its twisting behavior using the finite element method on microstructure elements computation, an analytical model, and we compare them to Eringen micropolar continuum. Notably, the results of the three models are in good qualitative and quantitative agreements. Finally, a systematic comparison of dispersion relations was made for the continuum and for the microstructures with different sizes in unit cells as final proof of perfect mapping.

description: In this paper, we study the Hamiltonian systems $ H\left( {y,x,ξ,\varepsilon } \right) = \left\langle {ω\left( ξ\right),y} \right\rangle + \varepsilon P\left( {y,x,ξ,\varepsilon } \right) $, where $ ω$ and $ P $ are continuous about $ ξ$. We prove that persistent invariant tori possess the same frequency as the unperturbed tori, under certain transversality condition and weak convexity condition for the frequency mapping $ ω$. As a direct application, we prove a KAM theorem when the perturbation $P$ holds arbitrary Hölder continuity with respect to parameter $ ξ$. The infinite dimensional case is also considered. To our knowledge, this is the first approach to the systems with the only continuity in parameter beyond Hölder's type.

description: Unlike for bipartite states consisting of distinguishable particles, in the case of identical parties the notion of entanglement is still under debate. In the following, we review two different approaches to the entanglement of systems consisting of two Bosons or Fermions; the first approach is based on the particle aspect typical of first quantization and identifies separable pure states as those that allow to assign two orthogonal single particle vector states to both parties. The second approach makes full use of the mode aspect of second quantization whereby separability can be formulated as absence of non-local correlation among two different sets of modes. While the first approach applies to pure states only, the second one is more general and characterizes generic entangled states. In the following, we shall show that the mode-based approach indeed contains the particle-based one.

description: Clever sampling methods can be used to improve the handling of big data and increase its usefulness. The subject of this study is remote sensing, specifically airborne laser scanning point clouds representing different classes of ground cover. The aim is to derive a supervised learning model for the classification using CARTs. In order to measure the effect of different sampling methods on the classification accuracy, various experiments with varying types of sampling methods, sample sizes, and accuracy metrics have been designed. Numerical results for a subset of a large surveying project covering the lower Rhine area in Germany are shown. General conclusions regarding sampling design are drawn and presented.

description: Gate-set tomography (GST) characterizes the process matrix of quantum logic gates, along with measurement and state preparation errors in quantum processors. GST typically requires extensive data collection and significant computational resources for model estimation. We propose a more efficient GST approach for qudits, utilizing the qudit Hadamard and virtual Z gates to construct fiducials while assuming virtual Z gates are error-free. Our method reduces the computational costs of estimating characterization results, making GST more practical at scale. We experimentally demonstrate the applicability of this approach on a superconducting transmon qutrit.

description: The local character of self-gravity along with the number of spatial dimensions are critical issues when computing the potential and forces inside massive systems like stars and disks. This appears from the discretisation scale where each cell of the numerical grid is a self-interacting body in itself. There is apparently no closed-form expression yet giving the potential of a three-dimensional homogeneous cylindrical or spherical cell, in contrast with the Cartesian case. By using Green's theorem, we show that the potential integral for such polar-type 3D sectors -- initially, a volume integral with singular kernel -- can be converted into a regular line-integral running over the lateral contour, thereby generalising a formula already known under axial symmetry. It therefore is a step towards the obtention of another potential/density pair. The new kernel is a finite function of the cell's shape (with the simplest form in cylindrical geometry), and mixes incomplete elliptic integrals, inverse trigonometric and hyperbolic functions. The contour integral is easy to compute; it is valid in the whole physical space, exterior and interior to the sector itself and works in fact for a wide variety of shapes of astrophysical interest (e.g. sectors of tori or flared discs). This result is suited to easily providing reference solutions, and to reconstructing potential and forces in inhomogeneous systems by superposition. The contour integrals for the 3 components of the acceleration vector are explicitely given.

description: Unmanned Aerial Vehicles (UAVs) are known for their fast and versatile applicability. With UAVs' growth in availability and applications, they are now of vital importance in serving as technological support in search-and-rescue(SAR) operations in marine environments. High-resolution cameras and GPUs can be equipped on the UAVs to provide effective and efficient aid to emergency rescue operations. With modern computer vision algorithms, we can detect objects for aiming such rescue missions. However, these modern computer vision algorithms are dependent on numerous amounts of training data from UAVs, which is time-consuming and labor-intensive for maritime environments. To this end, we present a new benchmark suite, SeaDroneSim, that can be used to create photo-realistic aerial image datasets with the ground truth for segmentation masks of any given object. Utilizing only the synthetic data generated from SeaDroneSim, we obtain 71 mAP on real aerial images for detecting BlueROV as a feasibility study. This result from the new simulation suit also serves as a baseline for the detection of BlueROV.

Simultaneous suppression of time and energy uncertainties in a single-photon frequency comb state

description: A single photon prepared in a time-energy state described by a frequency comb combines the extreme precision of energy defined by a single tooth of the comb with a high sensitivity to small shifts in time defined by the narrowness of a single pulse in the long sequence of pulses that describe the frequency comb state in the time domain. We show how this simultaneous suppression of time and energy uncertainties can be described by a separation of scales and compare this with the suppression of uncertainties in the two particle correlations of an entangled state. To illustrate the sensitivity of the frequency comb states to small shifts in time and frequency, we consider the Hong-Ou-Mandel dips observed in two-photon interference when both time- and frequency shifts between the input photons are varied. It is shown that the interference of two photons in equivalent frequency comb states results in a two dimensional Hong-Ou-Mandel dip that is narrow in both time and frequency, while the corresponding entangled photon pairs are only sensitive to temporal shifts. Frequency comb states thus represent a unique and different approach towards quantum operations beyond the uncertainty limit.

description: Advances in material architectures have enabled endowing materials with exotic attributes not commonly available in the conventional realm of mechanical engineering. Twisting, a mechanism whereby metamaterials are used to transform static axial load into twist motion, is of particular interest to this study. Herein, computations based on the finite element method, corroborated by an analytical approach derived from applying Lagrange's equations to a monoatomic spring-mass system, are employed to explore the longitudinal-twist (L-T) conversion exhibited by a chiral tetragonal-beam metamaterial. Firstly, we perform an eigenvalue analysis taking into account the polarization states to highlight the potential contribution of the longitudinal mode in the L-T conversion. We contrast the twisting behavior of the chiral cell with that of other homogeneous medium, octagonal-tube, and non-chiral cells. Moreover, we demonstrate the influence of the cell's chirality on the L-T conversion using both time-domain and frequency-domain studies. The findings indicate that at least a portion of the longitudinally propagating wave is transformed into twist throughout a broad frequency range and even quasi-totally converted at distinct frequencies.

description: In this work, we report our results on the geometric and electronic properties of hybrid graphite-like structure made up of silicene and boron nitride (BN) layers. We predict from our calculations that this hybrid bulk system, with alternate layers of honeycomb silicene and BN, possesses physical properties similar to those of bulk graphite. We observe that there exists a weak van der Waals interaction between the layers of this hybrid system in contrast to the strong inter-layer covalent bonds present in multi-layers of silicene. Furthermore, our results for the electronic band structure and the density of states show that it is a semi-metal and the dispersion around the Fermi level (E_F) is parabolic in nature and thus the charge carriers in this system behave as \textit{Nearly-Free Particle-Like}. These results indicate that the electronic properties of the hybrid bulk system resemble closely those of bulk graphite. Around E_F the electronic band structures have contributions only from silicene layers and the BN layer act only as a buffer layer in this hybrid system since it does not contribute to the electronic properties near E_F. In case of bi-layers of silicene with a single BN layer kept in between, we observe a linear dispersion around E_F similar to that of graphene. However, the characteristic linear dispersion become parabola-like when the system is subjected to a compression along the transverse direction. Our present calculations show that the hybrid system based on silicon and BN can be a possible candidate for two dimensional layered system akin to graphite and multi-layers of graphene.

description: We show that the recently discovered Mathieu moonshine plays a role for certain four dimensional theories with $\mathcal{N}=1$ supersymmetry. These theories are obtained from the $E_8 \times E_8$ heterotic string theory by compactifying on toroidal orbifolds. We find that a universal contribution to the holomorphic gauge kinetic function can be expanded in such a way that the expansion coefficients are the dimensions of representations of the Mathieu group M$_{24}$.
