description: Nel saggio si propone, a partire dai più conosciuti riferimenti novellistici già ampiamente indagali, un’ulteriore analisi del rapporto esistente tra i Sei personaggi in cerca d'autore e le Novelle per un anno, in particolare, l'analisi si concentra su Scialle nero, primo volume del corpus novellistico, pubblicato nel 1922, solo un anno dopo la prima rappresentazione dei Sei personaggi. Con rilievi tratti dal sistema variantistico alla base della raccolta vengono rintracciati qui alcuni snodi tematico-formali comuni, presenti in particolare nelle novelle Scialle nero e II Pipistrello. Ciò conferma le Novelle per un anno quale corpus incompiuto ma fortemente voluto e coeso, in stretto rapporto con il resto della prefazione pirandelliana.
description: This essay aims to provide the relationship between Sei personaggi in cerca d’autore and Novelle per un anno, with a focus on Scialle nero, first volume of the novelistic corpus, published in 1922, only one year after the first representation of Sei personaggi. Here is a thematic analysis of Scialle nero (especially Scialle nero and Il Pipistrello) through charaeters, places, structure and the different drafts of each text of the collection. The study on the different editions has brought out important issues, which confirm the Novelle per un anno as an unfinished work but strongly wanted and cohesive, in close rclationship with other Pirandellian works.

description: This paper presents real-time guidance strategies for unmanned aerial vehicles (UAVs) that can be used to enhance their flight endurance by utilizing {\sl insitu} measurements of wind speeds and wind gradients. In these strategies, periodic adjustments would be made in the airspeed and/or heading angle command for the UAV to minimize a projected power requirement at some future time. In this paper, UAV flights are described by a three-dimensional dynamic point-mass. Onboard closed-loop trajectory tracking logics that follow airspeed vector commands are modeled using the method of feedback linearization. A generic wind field model is assumed that consists of a constant term plus terms that vary sinusoidally with respect to the location. To evaluate the benefits of these strategies in enhancing UAV flight endurance, a reference strategy is introduced in which the UAV would seek to follow the desired airspeed in a steady level flight under zero wind. A performance measure is defined as the average power consumption both over a specified time interval and over different initial heading angles of the UAV. A relative benefit criterion is then defined as the percentage improvement of the performance measure of a proposed strategy over that of the reference strategy. Extensive numerical simulations are conducted. Results demonstrate the benefits and trends of power savings of the proposed real-time guidance strategies.

Classical dynamical localization

Subjects: subject: Quantum Physics (quant-ph)

description: We consider classical models of the kicked rotor type, with piecewise linear kicking potentials designed so that momentum changes only by multiples of a given constant. Their dynamics display quasi-localization of momentum, or quadratic growth of energy, depending on the arithmetic nature of the constant. Such purely classical features mimic paradigmatic features of the {\it quantum} kicked rotor, notably dynamical localization in momentum, or quantum resonances. We present a heuristic explanation, based on a classical phase space generalization of a well known argument, that maps the quantum kicked rotor on a tight-binding model with disorder. Such results suggest reconsideration of generally accepted views, that dynamical localization and quantum resonances are a pure result of quantum coherence.

We studied movement and abundance of barbel, Barbus barbus, over three years (October 1995 to September 1998) in two stretches (Woolmer's Park, Holwell Bridge) of a section of the River Lee (Hertfordshire, England) delimitated by water retention structures. Of 349 tagged individuals (168 at Woolmer's Park: 181 at Holwell Bridge), 51.8 % and 13.3 % respectively were recaptured at least once, with a much higher rate of multiple recaptures at Woolmer's Park, where monitoring of movements was over a longer period, than at Holwell Bridge, where too few recaptures were made for further movement analysis. At Woolmer's Park, 77.1 % of the barbel showed limited (i.e. resident component) and the rest greater betweencapture movements (i.e. mobile component). There was no preferential directional movement across size classes. Based on the available recapture data, population size (estimated through a Bayesian method) first increased moderately (1995-96) and then sharply (1996-97) at Woolmer's Park, and even further later at Holwell Bridge (1998-99). This may reflect a recovery phase in the local population, or possibly a rising part of a cyclic recruitment pattern, such as reported for barbel elsewhere and for other cyprinids in the UK. Habitat enhancement is recommended over stocking, given the adequate abundance of barbel in areas with suitable habitat. However, it remains unclear whether fencing-off of the banks from livestock will enhance 0+ barbel numbers, which appear to be low relative to some European rivers of similar width and depth.

We show that our definition provides a compact automaton, much smaller than the one obtained by applying the Aho-Corasick construction. We study properties of this automaton and present an efficient implementation of the automaton construction. We also present some experimental results and show that this automaton can be successfully applied to more general situations.

description: In this paper, we address the problem of enumerating all induced subtrees in an input k-degenerate graph, where an induced subtree is an acyclic and connected induced subgraph. A graph G = (V, E) is a k-degenerate graph if for any its induced subgraph has a vertex whose degree is less than or equal to k, and many real-world graphs have small degeneracies, or very close to small degeneracies. Although, the studies are on subgraphs enumeration, such as trees, paths, and matchings, but the problem addresses the subgraph enumeration, such as enumeration of subgraphs that are trees. Their induced subgraph versions have not been studied well. One of few example is for chordless paths and cycles. Our motivation is to reduce the time complexity close to O(1) for each solution. This type of optimal algorithms are proposed many subgraph classes such as trees, and spanning trees. Induced subtrees are fundamental object thus it should be studied deeply and there possibly exist some efficient algorithms. Our algorithm utilizes nice properties of k-degeneracy to state an effective amortized analysis. As a result, the time complexity is reduced to O(k) time per induced subtree. The problem is solved in constant time for each in planar graphs, as a corollary.

description: The main aim of this paper is to introduce the most important observables that help us to investigate stellar dynamos and compare those to the modeling results. We give an overview of the available observational methods and data processing techniques that are suitable for such purposes, with touching upon examples of inadequate interpretations as well. Stellar observations are compared to the solar data in such a way, which ensures that the measurements are comparable in dimension, wavelength, and timescale. A brief outlook is given to the future plans and possibilities. A thorough review of this topic was published nearly a decade ago (Berdyugina 2005), now we focus on the experience that have been gathered since that time.

description: La Trobe University Faculty of Science, Technology and Engineering Murray Darling Freshwater Research Centre

MDFRC item.

To determine if the Murray cod Maccullochella peehi peehi is an apex predator in the lowland rivers of the Murray-Darling Basin, its feeding ecology was compared with that of the sympatric top predator, golden perch Macquaria ambigua ambigua based on samples supplied by recreational anglers. Diet and prey size were reconstructed from alimentary tract contents of Murray cod (N = 39) and golden perch (N = 52), and their feeding morphology was assessed and included calculation of lengthgape relationships and relative gut index. Both species fed principally on fish and decapods although Murray cod was the more piscivorous (frequency of occurrence 44% versus 6%, total number 50% versus 2%, total weight 90.4% versus 16.0%). Based on reconstructions of prey sizes, fishes up to 1 kg in weight were preyed on by Murray cod, distinguishing it from other top predatory fishes in the Murray-Darling Basin and supporting its classification as an apex predator.
Linear magnetoelectricity at room temperature in perovskite superlattices by design

description: Discovering materials that display a linear magnetoelectric effect at room temperature is challenge. Such materials could facilitate novel devices based on the electric-field control of magnetism. Here we present simple, chemically intuitive design rules to identify a new class of bulk magnetoelectric materials based on the 'bicolor' layering of $Pnma$ ferrite perovskites, e.g., LaFeO$_3$/ LnFeO$_3$ superlattices for which Ln = lanthanide cation. We use first-principles density-functional theory calculations to confirm these ideas. Additionally, we elucidate the origin of this effect and show it is a general consequence of the layering of any bicolor, $Pnma$ perovskite superlattice in which the number of constituent layers are odd (leading to a form of hybrid improper ferroelectricity) and Goodenough- Kanamori rules. Here, the polar distortions induce both weak ferromagnetism and a linear magnetoelectric effect. Our calculations suggest that the effect is 2-3 times greater in magnitude than that observed for the prototypical magnetoelectric material, Cr$_2$O$_3$. We use a simple mean field model to show that the considered materials order magnetically above room temperature.

description: A current promising field of research, laser-driven ion acceleration has the potential to reduce the size, cost, and energy consumption of particle accelerators by orders of magnitude. To better refine the instrumentation, we have developed a virtual diagnostic to measure electromagnetic radiation such as radiation produced from scattered and transmitted laser beams which has been implemented into WarpX, an advanced Particle-in-Cell code that simulates laser-driven particle acceleration. This “FieldProbe” diagnostic provides field measurements and is parallelized using the Message Passing Interface (MPI) and can thus run on High Performance Computing systems such as the NERSC Cori cluster.

description: This work aims at the definition, application and validation of a simplified performance-based method for the evaluation of seismic performances of steel buildings. Reference is made to steel Moment Resisting Frames (MRFs) and “X” shaped Concentrically Braced Frames (CBFs) structural types. The simplified method allows to define the capacity curve of a structure by using the elastic and rigid plastic analyses extended to second order effects and has been calibrated through a wide regression analysis on 420 structures designed for each structural type. As a result, a trilinear simplified capacity curve has been defined. To check the accuracy of the method, compared with other tools given by codes, in addition to pushover analysis, incremental dynamic analyses (IDA) have been carried out. These analyses have been developed on real structures and simulated designs in accordance with recent and old codes, to analyze different design philosophies. The final section summarizes the comparison in terms of capacity between the proposed simplified methodology and the IDA, according to the limit states provided by the current codes.

description: Questo lavoro mira alla definizione, applicazione e validazione di un metodo semplificato basato sui livelli prestazionali per la valutazione delle performance sismiche degli edifici in acciaio. Si fa riferimento ai Moment Resisting Frames (MRF) in acciaio ai Concentrically Braced Frames (CBF) con controventi a "X". Il metodo semplificato permette di definire la curva di capacità di una struttura utilizzando l’analisi elastica e l’analisi rigido plastica estesa agli effetti del secondo ordine. Inoltre, è stato calibrato attraverso un'ampia analisi di regressione su 420 strutture progettate per ogni tipologia strutturale. Su tali basi, è stata definita una curva di capacità semplificata trilineare. Per verificare l'accuratezza del metodo, rispetto ad altri strumenti forniti dai codici, oltre all'analisi pushover, sono state effettuate analisi dinamiche incrementali (IDA). Queste analisi sono state sviluppate su strutture reali e progetti simulati in conformità con codici recenti e obsoleti, per analizzare diverse filosofie di progettazione. La sezione finale riassume il confronto in termini di capacità tra la metodologia semplificata proposta e le analisi dinamiche incrementali (IDA), secondo gli stati limite previsti dagli attuali codici.

A six-part collisional model of the main asteroid belt

description: In this work, we construct a new model for the collisional evolution of the main asteroid belt. Our goals are to test the scaling law of Benz and Asphaug (1999) and ascertain if it can be used for the whole belt. We want to find initial size-frequency distributions (SFDs) for the considered six parts of the belt (inner, middle, 'pristine', outer, Cybele zone, high-inclination region) and to verify if the number of synthetic asteroid families created during the simulation matches the number of observed families as well. We used new observational data from the WISE satellite (Masiero et al., 2011) to construct the observed SFDs. We simulate mutual collisions of asteroids with a modified version of the Boulder code (Morbidelli et al., 2009), where the results of hydrodynamic (SPH) simulations of Durda et al. (2007) and Benavidez et al. (2012) are included. Because material characteristics can significantly affect breakups, we created two models - for monolithic asteroids and for rubble-piles. To explain the observed SFDs in the size range D = 1 to 10 km we have to also account for dynamical depletion due to the Yarkovsky effect. The assumption of (purely) rubble-pile asteroids leads to a significantly worse fit to the observed data, so that we can conclude that majority of main-belt asteroids are rather monolithic. Our work may also serve as a motivation for further SPH simulations of disruptions of smaller targets (with a parent body size of the order of 1 km).

description: We mapped 3 mm continuum and line emission from the starburst galaxy M82 using the Combined Array for Research in Millimeter-wave Astronomy. We targeted the HCN, HCO$^{+}$, HNC, CS and HC$_{3}$N lines, but here we focus on the HCN and HCO$^{+}$ emission. The map covers a field of 1.2' with a ~5" resolution. The HCN and HCO$^{+}$ observations are combined with single dish images. The molecular gas in M82 had been previously found to be distributed in a molecular disk, coincident with the central starburst, and a galactic scale outflow which originates in the central starburst. With the new short spacings-corrected maps we derive some of the properties of the dense molecular gas in the base of the outflow. From the HCN and HCO$^{+}$ J=(1-0) line emission, and under the assumptions of the gas being optically thin and in local thermodynamic equilibrium, we place lower limits to the amount of dense molecular gas in the base of the outflow. The lower limits are $7\times10^{6}$ $M_{\odot}$ and $21\times10^{6}$ $M_{\odot}$, or $\gtrsim2\%$ of the total molecular mass in the outflow. The kinematics and spatial distribution of the dense gas outside the central starburst suggests that it is being expelled through chimneys. Assuming a constant outflow velocity, the derived outflow rate of dense molecular gas is $\geq0.3$ $M_{\odot}$ yr$^{-1}$, which would lower the starburst lifetime by $\geq5\%$. The energy required to expel this mass of dense gas is $(1-10)\times10^{52}$ erg.

description: We consider collective oscillations of neutrinos, which are emergent nonlinear flavor evolution phenomena instigated by neutrino-neutrino interactions in astrophysical environments with sufficiently high neutrino densities. We investigate the symmetries of the problem in the full three flavor mixing scheme and in the exact many-body formulation by including the effects of CP violation and neutrino magnetic moment. We show that, similar to the two flavor scheme, several dynamical symmetries exist for three flavors in the single-angle approximation if the net electron background in the environment and the effects of the neutrino magnetic moment are negligible. Moreover, we show that these dynamical symmetries are present even when the CP symmetry is violated in neutrino oscillations. We explicitly write down the constants of motion through which these dynamical symmetries manifest themselves in terms of the generators of the SU(3) flavor transformations. We also show that the effects due to the CP-violating Dirac phase factor out of the many-body evolution operator and evolve independently of nonlinear flavor transformations if neutrino electromagnetic interactions are ignored. In the presence of a strong magnetic field, CP-violating effects can still be considered independently provided that an effective definition for neutrino magnetic moment is used.

description: We study the energy dependent photon variability from a thermal Comptonizing plasma that is oscillating at kHz frequencies. In particular, we solve the linearised time dependent Kompaneets equation and consider the oscillatory perturbation to be either in the soft photon source or in the heating rate of the plasma. For each case, we self consistently consider the energy balance of the plasma and the soft photon source. The model incorporates the possibility of a fraction of the Comptonized photons impinging back into the soft photon source. We find that when the oscillation is due to the soft photon source, the variation of the fractional root mean sqaure (r.m.s) is nearly constant with energy and the time-lags are hard. However, for the case when the oscillation is due to variation in the heating rate of the corona, and when a significant fraction of the photons impinge back into the soft photon source, the r.m.s increases with energy and the time lags are soft. As an example, we compare the results with the $\sim 850$ Hz oscillation observed on March 3, 1996 for 4U 1608-52 and show that both the observed soft time-lags as well as the r.m.s versus energy can be well described by such a model where the size of the Comptonizing plasma is $\sim 1$ km. Thus, modelling of the time lags as due to Comptonization delays, can provide tight constraints on the size and geometry of the system. Detailed analysis would require well constrained spectral parameters.

description: In this paper we study the optical properties of $U(1)$ spin liquids with large spinon Fermi surfaces based on a simple formula for the bulk optical conductivity obtained through the Ioffe-Larkin composition rule. We show that the optical conductivity of $U(1)$ spin liquids at energies above the charge gap has a unique feature that distinguishes them from ordinary insulators. In particular we show the existence of a long-life surface plasmon mode propagating along the interface between a linear medium and the spin liquid at frequencies above the charge gap, which can be detected by the widely used Kretschmann-Raether three-layer configuration.

Roche tomography of cataclysmic variables - VI. Differential rotation of AE Aqr - Not tidally locked!

description: We present Roche tomograms of the K4V secondary star in the cataclysmic variable AE Aqr, reconstructed from two datasets taken 9 days apart, and measure the differential rotation of the stellar surface. The tomograms show many large, cool starspots, including a large high-latitude spot and a prominent appendage down the trailing hemisphere. We find two distinct bands of spots around 22$^{\circ}$ and 43$^{\circ}$ latitude, and estimate a spot coverage of 15.4-17% on the northern hemisphere. Assuming a solar-like differential rotation law, the differential rotation of AE Aqr was measured using two different techniques. The first method yields an equator-pole lap time of 269 d and the second yields a lap time of 262 d. This shows the star is not fully tidally locked, as was previously assumed for CVs, but has a co-rotation latitude of $\sim 40^{\circ}$. We discuss the implications that these observations have on stellar dynamo theory, as well as the impact that spot traversal across the first Lagrangian point may have on accretion rates in CVs as well as some of their other observed properties. The entropy landscape technique was applied to determine the system parameters of AE Aqr. For the two independent datasets we find M$_1$ = 1.20 and 1.17 M$_{\odot}$, M$_2$ = 0.81 and 0.78 M$_{\odot}$, and orbital inclinations of $50^{\circ}$ to $51^{\circ}$ at optimal systemic velocities of γ = -64.7 and -62.9 kms$^{-1}$.

description: We present a self-consistent model for the study of the structure of a neutron star in strong magnetic fields. Starting from a microscopic Lagrangian, this model includes the effect of the magnetic field on the equation of state, the interaction of the electromagnetic field with matter (magnetisation), and anisotropies in the energy-momentum tensor, as well as general relativistic aspects. We build numerical axisymmetric stationary models and show the applicability of the approach with one example quark matter equation of state (EoS) often employed in the recent literature for studies of strongly magnetised neutron stars. For this EoS, the effect of inclusion of magnetic field dependence or the magnetisation do not increase the maximum mass significantly in contrast to what has been claimed by previous studies.

CCI
digitisation

description: Previous studies show that micro and small enterprises in creative and cultural industries (CCIs) tend to be influenced by physical co-location – the agglomeration. A high level of agglomeration is, however, in many senses the opposite to digitalisation: there is a contrast between operating an enterprise based on face-to-face contacts and physical attendance and operating one based on digital contacts and a digitally managed value chain. Existing studies indicate two gaps in the research of the digitisation of CCI experiencing crucial changes in digitisation and especially during the ongoing COVID-19 pandemic2 . First, there is a lack of knowledge regarding how the two macro-trends of agglomeration and digitalisation in CCIs are related to each other, for example leaving it open whether agglomeration offers support in digitalising enterprises. Second, there is a lack of knowledge regarding how digitalisation and especially digitalisation in the context of the recent COVID-19 pandemic affects the strongly agglomerating CC enterprises. For example, it is unclear whether it initiates a structural change within strongly agglomerated CC enterprises. This interim report offers an account of the changing entrepreneurship patterns of agglomerated CC enterprises located in gentrifying urban neighbourhoods. This interim report serves as an input to the next report D4.5 which pays particular attention to the new emerging business models and their intellectual property (IP) issues. It also provides the scoping input for WP4, considering that one of the goals of the reCreating Europe consortium is to understand what constitutes a proper balance between copyright protection and limitations if the purpose is stimulating creativity and diffusion.

description: There are two disjointed problems in cosmology within General Relativity (GR), which can be addressed simultaneously by studying the nature of geodesics around $t\rightarrow 0$, where $t$ is the physical time. One is related to the past geodesic completeness of the inflationary trajectory due to the presence of a cosmological singularity, and the other one is related to the homogeneity condition required to inflate a local space-time patch of the universe. We will show that both the problems have a common origin, arising from how the causal structure of null and timelike geodesics are structured within GR. In particular, we will show how a non-local extension of GR can address both problems, while satisfying the null energy condition for the matter sources.
