description: This contribution is an analysis on the consequences of the coronavirus spread in the Italian prison system, highlighting concerns and potential prospects of improvements. Like other extremely vulnerable contexts, prisons are affected by the spread of Covid-19, resulting however weaker in providing effective strategies to ensure prevention, health and safety. Due to structural flaws, unhealthy conditions and endemic shortfalls, penitentiaries see a high risk of an outbreak of the illness. The prison crumbling and chronic overcrowded state make social distancing impossible. In addition to this, the coronavirus impact exacerbates pre-existing difficulties of the prison system. In such a dramatic scenario, and in spite of the inadequate government response in providing efficient resources against the virus diffusion, some detention facilities seem to be resilient in fighting back the epidemic, adopting strategies and solutions which could be considered a valuable starting point towards a better way of conceiving punishment. Il carcere italiano di fronte al coronavirus: tra criticità e resilienza. Il contributo presenta un’analisi circa le ripercussioni della diffusione del coronavirus nel sistema penitenziario, mettendo in luce le criticità e le potenziali prospettive di miglioramento. Il carcere, come tutti gli altri contesti contraddistinti da un elevato grado di vulnerabilità, non è immune rispetto alla diffusione del Covid-19, ma si dimostra debole nel garantire efficaci strategie di prevenzione e sicurezza sanitaria. A causa delle carenze strutturali, dell’insalubrità e dei deficit endemici degli istituti di pena, appare concreto il rischio che i luoghi di detenzione si trasformino in vivi focolai di malattia. Le fatiscenti condizioni dei penitenziari e la cronica condizione di sovraffollamento rendono impraticabile il distanziamento sociale e, al tempo stesso, l’impatto del coronavirus esaspera i nodi critici preesistenti all’interno dei circuiti penitenziari. In questo drammatico scenario, per quanto i provvedimenti adottati dal governo risultino insufficienti nel fornire gli strumenti adeguati al contrasto della diffusione del virus, alcune strutture si mostrano resilienti nel fronteggiare l’epidemia, mettendo in pratica una serie di strategie e soluzioni che possono costituire un valido punto di partenza verso un modo migliore di intendere la pena.

Stability of blow-up profile and lower bounds for blow-up rate for the critical generalized KdV equation

description: The generalized Korteweg-de Vries equations are a class of Hamiltonian systems in infinite dimension derived from the KdV equation where the quadratic term is replaced by a higher order power term. These equations have two conservation laws in the energy space H^1(L^2 norm and energy). We consider in this paper the {\it critical} generalized KdV equation, which corresponds to the smallest power of the nonlinearity such that the two conservation laws do not imply a bound in H^1 uniform in time for all H^1 solutions (and thus global existence). From [15], there do exist for this equation solutions u(t) such that |u(t)|_{H^1} \to +\infty as T\uparrow T, where T\le +\infty (we call them blow-up solutions). The question is to describe, in a qualitative way, how blow up occurs. For solutions with L^2 mass close to the minimal mass allowing blow up and with decay in L^2 at the right, we prove after rescaling and translation which leave invariant the L^2 norm that the solution converges to a {\it universal} profile locally in space at the blow-up time T. From the nature of this profile, we improve the standard lower bound on the blow-up rate for finite time blow-up solutions.

description: Recent stacked ALMA observations have revealed that normal, star-forming galaxies at $z\approx 6$ are surrounded by extended ($\approx 10\,\mathrm{kpc}$) [CII] emitting halos which are not predicted by the most advanced, zoom-in simulations. We present a model in which these halos are the result of supernova-driven cooling outflows. Our model contains two free parameters, the outflow mass loading factor, $η$, and the parent galaxy dark matter halo circular velocity, $v_c$. The outflow model successfully matches the observed [CII] surface brightness profile if $η= 3.20 \pm 0.10$ and $v_c = 170 \pm 10{\,\rm km\,s^{-1}}$, corresponding to a dynamical mass of $\approx 10^{11}\, \mathrm{M}_\odot$. The predicted outflow rate and velocity range are $128 \pm 5 \,\mathrm{M}_\odot {\rm yr}^{-1}$ and $300-500 {\,\rm km\,s^{-1}}$, respectively. We conclude that: (a) extended halos can be produced by cooling outflows; (b) the large $η$ value is marginally consistent with starburst-driven outflows, but it might indicate additional energy input from AGN; (c) the presence of [CII] halos requires an ionizing photon escape fraction from galaxies $f_{\rm esc} \ll 1$. The model can be readily applied also to individual high-$z$ galaxies, as those observed, e.g., by the ALMA ALPINE survey now becoming available.

description: In the wake of a severe economic crisis in the 1980s Costa Rica abandoned an import substitution model of development adopted in the 1960s and implemented policies supporting foreign investment and the diversification of its exports. This study presents an application of the model proposed by Herzer and Nowak-Lehnmann to test the hypothesis that export diversification has contributed to economic growth in Costa Rica via externalities of learningby- doing and learning-by-exporting over the period of 1965–2006. After using the autoregressive distributed lags and dynamic ordinary least squares models no long-run relationship was found between export diversification and growth.

description: I performed photometric observations of the poorly studied cataclysmic variable IPHAS J013031.89+622132.3 and discovered very deep eclipses. I obtained observations over 14 nights for a total time of 50 hours during a time span of 6 months. Thanks to the long observation interval, I determined the orbital period with high precision, Porb=0.14935014+/-0.00000020 d. I derived the eclipse ephemeris, which, thanks to the precision of the orbital period, has a formal validity of 300 years. The average eclipse depth was 1.88+/-0.07 mag. The prominent parts of the eclipses were smooth and symmetrical. The average eclipse width, including extended asymmetric eclipse wings, was 0.18+/-0.01 phases or 40+/-2 min. The average orbital light curve did not show a prominent orbital hump. Because no dwarf nova outburst occurred during the 6 months of monitoring, this cataclysmic variable is likely to be a nova-like variable.

description: A latent segmentation modeling is used in this study to identify the heterogeneity of willingness-to-pay estimates for quality attributes and country-of-origin in the Korean beef market. Three distinctive groups of grocery shoppers are identified based on their level of concern (very, moderately, and not too concerned) about the use of antibiotics and genetically modified organism feed ingredients in beef production. Results indicate that the very concerned group values such attributes as antibiotics-free, genetically modified organism-free, and domestic production the most among the three groups. Results also suggest that the most important factor in determining grocery shoppers’ willingness-to-pay is country-of-origin for all three groups.

description: NRAO Very Long Baseline Array (VLBA) observations of NGC 4278, NGC 4374 (M84), NGC 6166, and M87 (NGC 4486) have been made at 43 GHz in an effort to image the jet collimation region. This is the first attempt to image the first three sources at 43 GHz using Very Long Baseline Interferometry (VLBI) techniques. These three sources were chosen because their estimated black hole mass and distance implied a Schwarzschild radius with large angular size, giving hope that the jet collimation regions could be studied. Phase referencing was utilize for the three sources because of their expected low flux densities. M87 was chosen as the calibrator for NGC 4374 because it satisfied the phase referencing requirements: nearby to the source and sufficiently strong. Having observed M87 for a long integration time, we have detected its sub-parsec jet, allowing us to confirm previous high resolution observations made by Junor, Biretta & Livio, who have indicated that a wide opening angle was seen near the base of the jet. Phase referencing successfully improved our image sensitivity, yielding detections and providing accurate positions for NGC 4278, NGC 4374 and NGC 6166. These sources are point dominated, but show suggestions of extended structure in the direction of the large-scale jets. However, higher sensitivity will be required to study their sub-parsec jet structure.

The quadratic is rejected in favor of one of the other functional forms in all cases. The FDB p values differed slightly from the single bootstrap p values. Buffalograss was slightly more profitable than bermudagrass and has the ability to use almost as much nitrogen as bermudagrass.

description: Elevated prices for major U.S. commodities have renewed interest in the price sensitivity of foreign demand facing the United States. Although the elasticity of foreign demand plays an important role in discussions of U.S. farm policy, it is also a parameter that is much debated with the majority of studies in this area published over 20 years ago. We provide new estimates of the elasticity of export demand for U.S. corn, soybeans, and wheat using updated data and empirical techniques. Our estimates are useful for practical policy analysis as well as for researchers seeking to parameterize large-scale simulation models.

description: We propose a new method for segmentation-free joint estimation of orthogonal planes, their intersection lines, relationship graph and corners lying at the intersection of three orthogonal planes. Such unified scene exploration under orthogonality allows for multitudes of applications such as semantic plane detection or local and global scan alignment, which in turn can aid robot localization or grasping tasks. Our two-stage pipeline involves a rough yet joint estimation of orthogonal planes followed by a subsequent joint refinement of plane parameters respecting their orthogonality relations. We form a graph of these primitives, paving the way to the extraction of further reliable features: lines and corners. Our experiments demonstrate the validity of our approach in numerous scenarios from wall detection to 6D tracking, both on synthetic and real data.

description: We revisit Carlip's approach to entropy counting. This analysis reemerged in a recently obtained Schwarzschild/CFT-correspondence as Sugawara-construction of a 2D stress-tensor. Here, for the example of a Schwarzschild black hole, we show how to single out diffeomorphisms forming in contrast to Carlip's analysis the full 2D local conformal algebra. We provide arguments, why their Hamiltonian generators are expected to be the symmetry generators of a possible conformal field theory describing the part of phase space responsible for black hole microstates. Then, we can infer central charges and temperatures of this CFT by inspecting the algebra of these Hamiltonian generators. Using this data in the Cardy-formula, precise agreement with the Bekenstein-Hawking entropy is found. Alternatively, we obtain the same CFT temperatures by thermodynamic considerations. Altogether, this suggests that the Hamiltonian generators need no corrections through possible non-canonical counterterms. We comment on the related recent work by Haco, Hawking, Perry, Strominger.

Pseudoinvariance and the extra degree of freedom in f(T) gravity

description: Nonlinear generalizations of teleparallel gravity entail the modification of a Lagrangian that is pseudoinvariant under local Lorentz transformations of the tetrad field. This procedure consequently leads to the loss of the local pseudoinvariance and the appearance of additional degrees of freedom (d.o.f.). The constraint structure of f(T) gravity suggests the existence of one extra d.o.f. when compared with GR, which should describe some aspect of the orientation of the tetrad. The purpose of this article is to better understand the nature of this extra d.o.f. by means of a toy model that mimics essential features of f(T) gravity. We find that the nonlinear modification of a Lagrangian L possessing a local rotational pseudoinvariance produces two types of solutions. In one case the original gauge-invariant variables -- the analogue of the metric in teleparallelism -- evolve like when governed by the (nondeformed) Lagrangian L; these solutions are characterized by a (selectable) constant value of its Lagrangian, which is the manifestation of the extra d.o.f. In the other case, the solutions do contain new dynamics for the original gauge-invariant variables, but the extra d.o.f. does not materialize because the Lagrangian remains invariant on-shell. Coming back to f(T) gravity, the first case includes solutions where the torsion scalar T is a constant, to be chosen at the initial conditions (extra d.o.f.), and no new dynamics for the metric is expected. The latter case covers those solutions displaying a genuine modified gravity; T is not a constant, but it is (on-shell) invariant under Lorentz transformations depending only on time. Both kinds of f(T) solutions are exemplified in a flat FLRW universe. Finally, we present a toy model for a higher-order Lagrangian with rotational invariance [analogous to f(R) gravity] and derive its constraint structure and number of d.o.f.

description: We present an implementation in conformal field theory (CFT) of local finite conformal transformations fixing a point. We give explicit constructions when the fixed point is either the origin or the point at infinity. Both cases involve the exponentiation of a Borel subalgebra of the Virasoro algebra. We use this to build coherent state representations and to derive a close analog of Wick's theorem for the Virasoro algebra. This allows to compute the conformal partition function in non trivial geometries obtained by removal of hulls from the upper half plane. This is then applied to stochastic Loewner evolutions (SLE). We give a rigorous derivation of the equations, obtained previously by the authors, that connect the stochastic Loewner equation to the representation theory of the Virasoro algebra. We give a new proof that this construction enumerates all polynomial SLE martingales. When one of the hulls removed from the upper half plane is the SLE hull, we show that the partition function is a famous local martingale known to probabilists, thereby unravelling its CFT origin.

description: Deploying deep models on embedded devices has been a challenging problem since the great success of deep learning based networks. Fixed-point networks, which represent their data with low bits fixed-point and thus give remarkable savings on memory usage, are generally preferred. Even though current fixed-point networks employ relative low bits (e.g. 8-bits), the memory saving is far from enough for the embedded devices. On the other hand, quantization deep networks, for example XNOR-Net and HWGQNet, quantize the data into 1 or 2 bits resulting in more significant memory savings but still contain lots of floatingpoint data. In this paper, we propose a fixed-point network for embedded vision tasks through converting the floatingpoint data in a quantization network into fixed-point. Furthermore, to overcome the data loss caused by the conversion, we propose to compose floating-point data operations across multiple layers (e.g. convolution, batch normalization and quantization layers) and convert them into fixedpoint. We name the fixed-point network obtained through such integrated conversion as Integrated Fixed-point Quantization Networks (IFQ-Net). We demonstrate that our IFQNet gives 2.16x and 18x more savings on model size and runtime feature map memory respectively with similar accuracy on ImageNet. Furthermore, based on YOLOv2, we design IFQ-Tinier-YOLO face detector which is a fixed-point network with 256x reduction in model size (246k Bytes) than Tiny-YOLO. We illustrate the promising performance of our face detector in terms of detection rate on Face Detection Data Set and Bencmark (FDDB) and qualitative results of detecting small faces of Wider Face dataset.

Specifically, we present the results of an ad hoc questionnaire administered to the students with disabilities and Specific Learning Disability (SLD) enrolled at the University of Calabria. Through this, we aimed to provide important insights, to be taken into account in the future, especially in view of the re-arrangement of the University’s teaching activities. Furthermore, we intended to highlight how universal design in the educational field should constitute a widespread and systematic working method for the creation of truly inclusive learning and relationship environments, also at a distance. Come immaginare una didattica universitaria post-Covid inclusiva. Il presente contributo si pone l’obiettivo di analizzare le criticità e i punti di forza della didattica a distanza (DaD) erogata durante questo periodo di emergenza sanitaria, analizzando le opinioni degli studenti e delle studentesse con disabilità e Disturbi Specifici dell’Apprendimento (DSA). In particolare, si presentano i risultati ottenuti tramite la somministrazione di un questionario ad hoc agli studenti e alle studentesse con disabilità e DSA iscritti presso l’Università della Calabria. In tal modo si auspica di fornire utili spunti di riflessione, dei quali tener conto in futuro, soprattutto in vista di una riorganizzazione delle attività didattiche dell’Ateneo. Si tenterà, inoltre, di mettere in luce come la progettazione universale in campo educativo debba costituire una modalità di lavoro diffusa e sistematica per la creazione di ambienti di apprendimento e relazione davvero inclusivi, anche a distanza.

description: We consider an intrinsic entropy associated with a local conformal net A by the coefficients in the expansion of the logarithm of the trace of the ``heat kernel'' semigroup. In analogy with Weyl theorem on the asymptotic density distribution of the Laplacian eigenvalues, passing to a quantum system with infinitely many degrees of freedom, we regard these coefficients as noncommutative geometric invariants. Under a natural modularity assumption, the leading term of the entropy (noncommutative area) is proportional to the central charge c, the first order correction (noncommutative Euler characteristic) is proportional to logμ_A, where μ_A is the global index of A, and the second spectral invariant is again proportional to c. We give a further general method to define a mean entropy by considering conformal symmetries that preserve a discretization of S^1 and we get the same value proportional to c. We then make the corresponding analysis with the proper Hamiltonian associated to an interval. We find here, in complete generality, a proper mean entropy proportional to logμ_A with a first order correction defined by means of the relative entropy associated with canonical states. By considering a class of black holes with an associated conformal quantum field theory on the horizon, and relying on arguments in the literature, we indicate a possible way to link the noncommutative area with the Bekenstein-Hawking classical area description of entropy.

description: The relatively large-amplitude decaying regime of transverse oscillations of coronal loops has been known for two decades and interpreted in terms of MHD kink modes of cylindrical plasma waveguides. Recent observational analysis has revealed the so-called decay-less small-amplitude oscillations, with a multi-harmonic structure being detected. Several models have been proposed to explain them. In particular, decay-less oscillations have been described in terms of standing kink waves driven with continuous monoperiodic motions of loop footpoints, in terms of a simple oscillator model of forced oscillations due to harmonic external force, and as a self-oscillatory process due to the interaction of a loop with quasi-steady flows. However, an alternative mechanism is needed to explain the simultaneous excitation of several longitudinal harmonics of the oscillation. We study the mechanism of random excitation of decay-less transverse oscillations of coronal loops. With a spatially one-dimensional and time-dependent analytical model taking into account effects of the wave damping and kink speed variation along the loop, we consider transverse loop oscillations driven by random motions of footpoints. The footpoint motions are modelled by broad-band coloured noise. We have found the excitation of loop eigenmodes and analysed their frequency ratios as well as the spatial structure of the oscillations along the loop. The obtained results successfully reproduce the observed properties of decay-less oscillations. In particular, excitation of eigenmodes of a loop as a resonator can explain the observed quasi-monochromatic nature of decay-less oscillations and generation of multiple harmonics detected recently. We propose the mechanism that can interpret decay-less transverse oscillations of coronal loops in terms of kink waves randomly driven at the loop footpoints.

description: The Covid-19 pandemic has brought to light many problematic knots within the Italian welfare state. The scientific literature produced in recent months has focused heavily on the impact that the pandemic has had in various sectors, neglecting over the data on social-educational services. The present study questions the role that the figure of the educator has had in the pandemic period and the possible effects that his or her involvement has produced both within the services in which he or she works and at the level of professional identity. The study presented here therefore offers a glimpse of the impact of Covid-19 on social-educational services, focusing on the function of technology in the remodeling of services provided and on the role of the educator. The research highlights how, despite the challenges and the initial disorientation, technologies can be, even in the social-educational and care contexts, an important instrument of integration for the continuity of the educational relationship. Il lavoro dell’educatore al tempo del Covid-19. Uno studio sull’impatto dell’emergenza sanitaria e sul ruolo delle tecnologie. La pandemia da Covid-19 ha fatto emergere molti nodi problematici all’interno del welfare state italiano. La letteratura scientifica prodotta negli ultimi mesi si è molto concentrata sull’impatto che la pandemia ha avuto in vari settori, glissando i dati relativi ai servizi socio-educativi. Il presente studio si interroga sul ruolo che la figura dell’educatore ha avuto nel periodo pandemico e sugli eventuali effetti che il suo coinvolgimento ha prodotto sia all’interno dei servizi in cui opera che a livello di identità professionale. Lo studio qui presentato offre dunque uno spaccato sull’impatto del Covid-19 sui servizi socio-educativi, focalizzandosi sulla funzione delle tecnologie nella rimodulazione dei servizi erogati e sul ruolo dell’educatore. La ricerca mette in luce come nonostante le sfide e l’iniziale disorientamento le tecnologie possano costituire, anche nei contesti socio-educativi ed assistenziali, un importante strumento di integrazione per la continuità della relazione educativa.

description: We investigate thinness of hog and pork markets in terms of quantity and representativeness of negotiated transactions. Transactional volume imparts marginally greater confidence in pricing precision for Iowa-Southern Minnesota negotiated hogs than for the national carcass cut-out, suggesting that contracts tying prices to the former rather than the latter may be more representative of industry conditions. Extending mandatory price reporting to pork may remedy this discrepancy. Despite declining volume, terminal hog markets may price accurately off of Iowa-Southern Minnesota prices. Hog quality differentials across procurement methods are documented, and quality of negotiated hogs is shown to decline with declining volume.

description: Fruit and vegetable consumption is associated with improved health outcomes, yet there is limited understanding of the impact of cost and accessibility on fruit and vegetable intake in rural settings. This study examines the relationship between the consumption of fruits and vegetables and their cost and accessibility among blacks and non-Hispanic whites in a rural area. Individual characteristics from a 2006 mail survey (n 5 1,510) were combined with store locations and price information from a 2006 ground-truthed census of retail outlets. The mail survey covered seven counties in central Texas with 38 supermarkets/grocery stores. Blacks tended to live closer to a supermarket or grocery store, but they were only slightly more likely than whites to consume two or more servings of fruit daily and much less likely to consume three or more servings of vegetables. Multivariate probit regression analysis revealed that neither access nor cost was related to fruit or vegetable consumption among white respondents. Among blacks, cost was also not associated with consumption. In contrast to whites, however, each additional mile was associated with a three percentage point decline in the probability of consuming two or more servings of fruit daily and a 1.8 percentage point decline in the probability of consuming three or more vegetable servings.
Challenges and Opportunities Raised by Covid-19 for the Judicial Systems in Europe

description: This contribution examines and analyses the challenges and opportunities created by the spread of Covid-19 for the European justice systems, putting them in relation with educational needs that are arising. The Covid-19 crisis has acted as a stress test, as unexpected as it is energic, for the resilience of national systems and has shed light on the lack or delay in the digitalisation of justice systems, whereas throughout Europe, due to the limited availability of the national systems, recourse to alternative dispute resolution mechanisms has increased. The adjustments that have been made necessary to deal with the period of Covid-19 could radically and permanently change the way justice will be rendered in the post-pandemic world, also creating an opportunity for evolution and modernisation. The need to draw on shared best practices for the development of new protocols to ensure an effective functioning of the justice system must be balanced with the respect of fundamental rights such as access to justice and right to a fair trial. To this end, all stakeholders in the judiciary face a steep learning curve for developing new skills necessary to actively and consciously take part in the paradigm shift that justice is encountering. Sfide e opportunità create dal Covid-19 per i sistemi giudiziari in Europa. Questo contributo prende in esame e analizza le sfide e le opportunità create dalla diffusione del Covid-19 per i sistemi giudiziari europei, mettendole in relazione con i bisogni formativi che stanno emergendo. La crisi legata al Covid-19 ha costituito uno stress test, inatteso quanto energico, per la resilienza dei sistemi nazionali e ha messo in evidenza la mancanza o il ritardo della digitalizzazione dei sistemi di giustizia, mentre in tutta Europa, a causa della disponibilità limitata dei sistemi nazionali, si è assistito ad un aumentato ricorso a modi alternativi di risoluzione delle controversie. Gli adeguamenti che si sono resi necessari durante il periodo del Covid-19 potrebbero modificare radicalmente e permanentemente il modo in cui la giustizia sarà resa nel mondo post-pandemico, creando anche opportunità di evoluzione e modernizzazione. La necessità di attingere a best practices condivise per lo sviluppo di nuovi protocolli e procedure atti a garantire un funzionamento efficace deve essere contemperata con il rispetto dei diritti fondamentali, quali l’accesso alla giustizia e il diritto ad un giusto processo. A tale scopo, tutte le parti interessate nel settore giudiziario si trovano ad affrontare una curva di apprendimento ripida per lo sviluppo delle nuove competenze necessarie ad una partecipazione attiva e consapevole al cambiamento di paradigma che la giustizia sta affrontando.

description: The artificial stacking of atomically thin crystals suffers from intrinsic limitations in terms of control and reproducibility of the relative orientation of exfoliated flakes. This drawback is particularly severe when the properties of the system critically depend on the twist angle, as in the case of the dodecagonal quasicrystal formed by two graphene layers rotated by 30$^\circ$. Here we show that large-area 30$^\circ$-rotated bilayer graphene can be grown deterministically by chemical vapor deposition on Cu, eliminating the need of artificial assembly. The quasicrystals are easily transferred to arbitrary substrates and integrated in high-quality hBN-encapsulated heterostructures, which we process into dual-gated devices exhibiting carrier mobility up to $10^5$ cm$^2$/Vs. From low-temperature magnetotransport, we find that the graphene quasicrystals effectively behave as uncoupled graphene layers, showing 8-fold degenerate quantum Hall states: this result indicates that the Dirac cones replica detected by previous photo-emission experiments do not contribute to the electrical transport.
