description: The phase diagram of the massive chiral Gross-Neveu model (the massive Nambu-Jona-Lasinio model in 1+1 dimensions) is constructed. In the large N limit, the Hartree-Fock approach can be used. We find numerically a chiral crystal phase separated from a massive Fermi gas phase by a 1st order transition. Using perturbation theory, we also construct the critical sheet where the homogeneous phase becomes unstable in a 2nd order transition. A tricritical curve is located. The phase diagram is mapped out as a function of fermion mass, chemical potential and temperature and compared with the one of the discrete chiral Gross-Neveu model. As a by-product, we illustrate the crystal structure of matter at zero temperature for various densities and fermion masses.

description: A fine structure related to the kinematic peculiarities of three components of the Scorpius-Centaurus association (LCC, UCL, and US) has been revealed in the UV-velocity distribution of Gould Belt stars. We have been able to identify the most likely members of these groups by applying the method of analyzing the two-dimensional probability density function of stellar UV velocities that we developed. A kinematic analysis of the identified structural components has shown that, in general, the center--of--mass motion of the LCC, UCL, and US groups follows the motion characteristic of the Gould Belt, notably its expansion. The entire Scorpius-Centaurus complex is shown to possess a proper expansion with an angular velocity parameter of 46+-8 km/s/kpc for the kinematic center with lo=-40 degrees and Ro=110 pc found. Based on this velocity, we have estimated the characteristic expansion time of the complex to be 21+-4 Myr. The proper rotation velocity of the Scorpius-Centaurus complex is lower in magnitude, is determined less reliably, and depends markedly on the data quality.

description: The $PeV$ cosmogenic neutrino is still interesting argument. Since cosmogenic neutrinos interact weakly with matter, the detection of their direction will precisely point out the source in the space. In this paper, we show the results of the simulation of tau lepton air showers induced by high energy neutrinos detected by an array of stations designed to use the Earth Skimming method improved by the "mountain chain screen" strategy. Both track time stamp and position information of the stations on the array are used to reconstruct the shower to estimate the direction and the number of events. The array studied consists of 640 stations ($40 \times 16$) spread over an area of $0.6\,km^2$ starting from $1500\,m$ above the sea level (a.s.l.) on $30^{o}$ inclined plane of the mountain. When we extrapolate to 3 years and 10 $km^2$ we estimate 13 tau lepton events in energy interval of 10 PeV to 1000 PeV detected using the present upper limits of tau neutrino flux.

Predictors of school psychologists' use of exposure interventions
Creators: name: Weiss, Sheva
Publisher: name: No Publisher Supplied
Year: 2021

description: Objective: Anxiety disorders are the most prevalent mental health conditions among school-aged children (Merikangas et al., 2010) and have negative consequences for youth in schools (Ingul et al., 2019; Langley et al., 2004). The school setting is an ideal venue for the provision of mental health services and presents opportunities for free and equitable access to services (Merikangas et al., 2011). Given that school psychologists are well-positioned to address mental health needs of youth (Kazak et al., 2010; Shernoff et al., 2017; Simon et al., 2015), this study examined school psychologists’ use of exposure, a highly effective but underutilized intervention for anxiety (Deacon, Farrell, et al., 2013; Freiheit et al., 2004; Kaczkurkin & Foa, 2015; van Minnen et al., 2010). The study assessed school psychologists’ patterns of knowledge, attitudes, comfort/self-efficacy, and training pertaining to exposure and investigated whether these variables influence their delivery of exposure. Method: School psychologists in the United States were anonymously surveyed online about their experience with exposure interventions. Participants were recruited through their graduate training program directors, school psychology state associations, and social media platforms. Data from 318 school psychologists were analyzed using descriptive statistics, correlational analyses, and multiple regression. Post hoc analyses explored potential mediators of use. Results: Over 50% of school psychologists did not use exposure interventions and their related knowledge, comfort/self-efficacy, and training significantly predicted their use of exposure. Attitudes were not found to uniquely predict use of exposure. Conclusion: Efforts to improve school psychologists’ knowledge, training, and comfort/self-efficacy through graduate training will likely result in improved delivery of exposure interventions for anxious youth in schools. Implications for future training of school psychologists are discussed.
Kinetic-growth self-avoiding walks on small-world networks

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)
subject: FOS: Physical sciences

description: Kinetically-grown self-avoiding walks have been studied on Watts-Strogatz small-world networks, rewired from a two-dimensional square lattice. The maximum length L of this kind of walks is limited in regular lattices by an attrition effect, which gives finite values for its mean value < L >. For random networks, this mean attrition length < L > scales as a power of the network size, and diverges in the thermodynamic limit (large system size N). For small-world networks, we find a behavior that interpolates between those corresponding to regular lattices and randon networks, for rewiring probability p ranging from 0 to 1. For p < 1, the mean self-intersection and attrition length of kinetically-grown walks are finite. For p = 1, < L > grows with system size as N^{1/2}, diverging in the thermodynamic limit. In this limit and close to p = 1, the mean attrition length diverges as (1-p)^{-4}. Results of approximate probabilistic calculations agree well with those derived from numerical simulations.

We prove some general topological properties of such manifolds, namely, vanishing of the Euler characteristic and real Pontryagin classes, and infiniteness of the fundamental group. We also show that, in the Lorentzian case, each of them is at least 5-dimensional and admits a two-fold cover which is a bundle over the circle.

Un’applicazione delle reti bayesiane nell’individuazione delle cause di incidente
Creators: name: Sparavigna, Lucia
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2005

description: La tesi di dottorato, Un’applicazione delle Reti Bayesiane nell’individuazione delle cause di incidente, propone una metodologia per valutare le condizioni che compromettono la sicurezza nella circolazione stradale (aumento della probabilità del verificarsi di un incidente) e che quindi sia di supporto per la scelta degli interventi da realizzare per mettere in sicurezza una strada.
L’analisi vera e propria inizia con un’attività di analisi preliminari delle variabili che descrivono il fenomeno. Si tratta dell’insieme delle caratteristiche strutturali e funzionali della strada, delle condizioni di traffico e di ambiente in corrispondenza delle quali si verifica un dato evento incidente. I parametri scelti per la caratterizzazione degli incidenti sono: localizzazione incidente, denominazione strada, tronco di strada, tipo di strada, intersezione, pavimentazione, segnaletica, fondo stradale, condizioni metereologiche, mese, ora.
Appare chiaro che, a causa del fatto che i parametri possono assumere più valori, il numero delle possibili combinazioni è tale da rendere la loro gestione manuale impraticabile.
A tal fine si è realizzato un sistema la cui modalità di funzionamento è contraddistinta in due fasi: apprendimento e classificazione.
La prima fase consiste nell’addestramento della rete bayesiana, ossia ad essa vanno mostrati gli esempi con l’indicazione della classe di appartenenza, in modo che la rete sia in grado di acquisire la conoscenza necessaria per distinguere campioni appartenenti a classi distinte. Tale fase è distinta nella vera e propria fase di training e in una successiva fase di test, necessaria per stabilire se il classificatore ha appreso in maniera corretta. Terminato l’addestramento, la rete viene utilizzata come classificatore: vengono ad essa sottoposti campioni non mostrati in precedenza di cui non è nota la classe di appartenenza.
Il sistema realizzato permette, quindi, di individuare le situazioni a più alto rischio di incidente e quindi di gestire concretamente la sicurezza stradale in una qualunque rete. Ciò permetterà di individuare a priori, note le caratteristiche ambientali e geometriche il livello di pericolosità di una strada.

description: The magnetic structure and the multiferroic relaxation dynamics of NaFeGe$_2$O$_6$ were studied by neutron scattering on single crystals partially utilizing polarization analysis. In addition to the previously reported transitions, the incommensurate spiral ordering of Fe$^{3+}$ moments in the $ac$ plane develops an additional component along the crystallographic $b$ direction below $T\approx 5\text{ K}$, which coincides with a lock-in of the incommensurate modulation. The quasistatic control of the spin-spiral handedness, respectively of the vector chirality, by external electric fields proves the invertibility of multiferroic domains down to the lowest temperature. Time-resolved measurements of the multiferroic domain inversion in NaFeGe$_2$O$_6$ reveal a simple temperature and electric-field dependence of the multiferroic relaxation that is well described by a combined Arrhenius-Merz relation, as it has been observed for TbMnO$_3$. The maximum speed of domain wall motion is comparable to the spin wave velocity.

description: We report highly efficient single photon generation from InGaAs self-assembled quantum dots emitting within a two-dimensional photonic bandgap. A strongly suppressed multiphoton probability is obtained for single quantum dots in bulk GaAs and those emitting into the photonic bandgap. In the latter case, photoluminescence saturation spectroscopy is employed to measure a ~17 times enhancement of the average photon extraction efficiency, when compared to quantum dots in bulk GaAs. For quantum dots in the photonic crystal we measure directly an external quantum efficiency up to 26%, much higher than for quantum dots on the same sample without a tailored photonic environment. The results show that highly efficient quantum dot single photon sources can be realized, without the need for complex nanopositioning techniques.

Year: 2006

description: Il sistema bancario italiano è stato investito da un profondo processo di consolidamento e ristrutturazione a partire dagli inizi degli anni novanta. Tale processo ha inciso profondamente sugli assetti organizzativi e sui modelli di comportamento degli intermediari, ha plasmato le relazioni banca-cliente, ha inciso sensibilmente sulla rilevanza della contiguità territoriale e dell’intangibilità delle informazioni. Questo lavoro si propone di indagare, avvalendosi di metodi econometrici di derivazione di frontiere stocastiche, quali siano stati gli esiti in termini di efficienza di questa profonda trasformazione della struttura del mercato del credito in Italia.  I risultati sollevano alcune perplessità sulla coerenza interna del nuovo disegno strutturale che sembra emergere dall’ondata di fusioni e acquisizioni che hanno preso il via con la recente fase di liberalizzazione del mercato.

description: Submillimeter interferometry has the potential to image supermassive black holes on event horizon scales, providing tests of the theory of general relativity and increasing our understanding of black hole accretion processes. The Event Horizon Telescope (EHT) performs these observations from the ground, and its main imaging targets are Sagittarius A* in the Galactic Center and the black hole at the center of the M87 galaxy. However, the EHT is fundamentally limited in its performance by atmospheric effects and sparse terrestrial $(u,v)$-coverage (Fourier sampling of the image). The scientific interest in quantitative studies of the horizon size and shape of these black holes has motivated studies into using space interferometry which is free of these limitations. Angular resolution considerations and interstellar scattering effects push the desired observing frequency to bands above 500 GHz. This paper presents the requirements for meeting these science goals, describes the concept of interferometry from Polar or Equatorial Medium Earth Orbits (PECMEO) which we dub the Event Horizon Imager (EHI), and utilizes suitable space technology heritage. In this concept, two or three satellites orbit at slightly different orbital radii, resulting in a dense and uniform spiral-shaped $(u,v)$-coverage over time. The local oscillator signals are shared via an inter-satellite link, and the data streams are correlated on-board before final processing on the ground. Inter-satellite metrology and satellite positioning are extensively employed to facilitate the knowledge of the instrument position vector, and its time derivative. The European space heritage usable for both the front ends and the antenna technology of such an instrument is investigated. Current and future sensors for the required inter-satellite metrology are listed. Intended performance estimates and simulation results are given.

description: Excitonic transitions offer a possible route to ultrafast optical spin manipulation in coupled nanostructures. We perform here a detailed study of the three principal exciton-mediated decoherence channels for optically-controlled electron spin qubits in coupled quantum dots: radiative decay of the excitonic state, exciton-phonon interactions, and Landau-Zener transitions between laser-dressed states. We consider a scheme to produce an entangling controlled-phase gate on a pair of coupled spins which, in its simplest dynamic form, renders the system subject to fast decoherence rates associated with exciton creation during the gating operation. In contrast, we show that an adiabatic approach employing off-resonant laser excitation allows us to suppress all sources of decoherence simultaneously, significantly increasing the fidelity of operations at only a relatively small gating time cost. We find that controlled-phase gates accurate to one part in 10^2 can realistically be achieved with the adiabatic approach, whereas the conventional dynamic approach does not appear to support a fidelity suitable for scalable quantum computation. Our predictions could be demonstrated experimentally in the near future.

description: Nell’ultimo quarto del Settecento, vedutisti di diverse nazionalità viaggiano attraverso l’Italia, in particolare da Roma si spingono sempre più a Meridione, raggiungendo la Sicilia e in alcuni casi anche il vicino Oriente, alla ricerca di testimonianze dell’antico e dei fenomeni naturali accompagnando i nobili stranieri che cercavano nella produzione di questi pittori la documentazione del loro viaggio. Attraverso l’analisi dell’attività di artisti come Giovan Battista Lusieri, Thomas Jones, John Robert Cozens, William Pars, Francis Towne, Abraham Louis Rodolph Ducros, Louis Jean Desprez, Jacob Philipp Hackert sono stati messi in evidenza rapporti e contatti e gli elementi in comune della loro produzione che vanno dalle escursioni pittoriche per realizzare disegni from nature, alle tecniche, ai soggetti dei dipinti, ai committenti che acquistano le loro vedute. Il catalogo di Lusieri è stato ampliato con l’acquisizione di nuovi dipinti e l’analisi di disegni inediti che aiutano a definire maggiormente la sua attività e i nuovi caratteri del vedutismo di fine secolo.

description: The simplest one-dimensional model for the studying of non-trivial geometrical effects is a ring shaped device which is formed by joining two arms. We explore the possibility to model such a system as a two level system (TLS). Of particular interest is the analysis of quantum stirring, where it is not evident that the topology is properly reflected within the framework of the TLS modeling. On the technical side we provide a practical "neighboring level" approximation for the analysis of such quantum devices, which remains valid even if the TLS modeling does not apply.

description: The ability to detect Out-of-Domain (OOD) inputs has been a critical requirement in many real-world NLP applications. For example, intent classification in dialogue systems. The reason is that the inclusion of unsupported OOD inputs may lead to catastrophic failure of systems. However, it remains an empirical question whether current methods can tackle such problems reliably in a realistic scenario where zero OOD training data is available. In this study, we propose ProtoInfoMax, a new architecture that extends Prototypical Networks to simultaneously process in-domain and OOD sentences via Mutual Information Maximization (InfoMax) objective. Experimental results show that our proposed method can substantially improve performance up to 20% for OOD detection in low resource settings of text classification. We also show that ProtoInfoMax is less prone to typical overconfidence errors of Neural Networks, leading to more reliable prediction results.

description: Starting from the full many body Hamiltonian we derive the leading order energy and density asymptotics for the ground state of a dilute, rotating Bose gas in an anharmonic trap in the ` Thomas Fermi' (TF) limit when the Gross-Pitaevskii coupling parameter and/or the rotation velocity tend to infinity. Although the many-body wave function is expected to have a complicated phase, the leading order contribution to the energy can be computed by minimizing a simple functional of the density alone.

description: This paper introduces an iterative tomogravity algorithm for the estimation of a network traffic matrix based on one snapshot observation of the link loads in the network. The proposed method does not require complete observation of the total load on individual edge links or proper tuning of a penalty parameter as existing methods do. Numerical results are presented to demonstrate that the iterative tomogravity method controls the estimation error well when the link data is fully observed and produces robust results with moderate amount of missing link data.

description: We found an unusual complex of narrow blue filaments, bright blue knots, and H-alpha emitting filaments and clouds, which morphologically resembled a complex of ``fireballs,'' extending up to 80 kpc south from an E+A galaxy RB199 in the Coma cluster. The galaxy has a highly disturbed morphology indicative of a galaxy--galaxy merger remnant. The narrow blue filaments extend in straight shapes toward the south from the galaxy, and several bright blue knots are located at the southern ends of the filaments. The Rc band absolute magnitudes, half light radii and estimated masses of the bright knots are -12 - -13 mag, 200 - 300 pc and 10^6-7 Msolar, respectively. Long, narrow H-alpha emitting filaments are connected at the south edge of the knots. The average color of the fireballs is B - Rc = 0.5, which is bluer than RB199 (B - R = 0.99), suggesting that most of the stars in the fireballs were formed within several times 10^8 yr. The narrow blue filaments exhibit almost no H-alpha emission. Strong H-alpha and UV emission appear in the bright knots. These characteristics indicate that star formation recently ceased in the blue filaments and now continues in the bright knots. The gas stripped by some mechanism from the disk of RB199 may be traveling in the intergalactic space, forming stars left along its trajectory. The most plausible fireball formation mechanism is ram pressure stripping by high-speed collision between the galaxy and the hot intra-cluster medium. The fireballs may be a snapshot of diffuse intra-cluster population formation, or halo star population formation in a cluster galaxy.

description: In the absence of an initial seed, the Biermann battery term of a non-ideal induction equation acts as a source that generates weak magnetic fields. These fields are then amplified via a dynamo mechanism. The Kelvin-Helmholtz instability is a fluid phenomenon that takes place in many astrophysical scenarios and can trigger the action of the Biermann battery and dynamo processes. We aim to investigate the effect that the ionisation degree of the plasma and the interaction between the charged and neutral species have on the generation and amplification of magnetic fields during the different stages of the instability. We use the two-fluid model implemented in the numerical code Mancha-2F. We perform 2D simulations starting from a configuration with no initial magnetic field and which is unstable due to a velocity shear. We vary the ionisation degree of the plasma and we analyse the role that the different collisional terms included in the equations of the model play on the evolution of the instability and the generation of magnetic field. We find that when no collisional coupling is considered between the two fluids, the effect of the Biermann battery mechanism does not depend on the ionisation degree. However, when elastic collisions are taken into account, the generation of magnetic field is increased as the ionisation degree is reduced. This behaviour is slightly enhanced if the process of charge-exchange is also considered. We also find a dependence on the total density of the plasma related to the dependence on the coupling degree between the two fluids. As the total density is increased, the results from the two-fluid model converge to the predictions of single-fluid models.

description: Electron-positron pair creation in supercritical electric fields limits the net charge of any static, spherical object, such as superheavy nuclei, strangelets, and Q-balls, or compact stars like neutron stars, quark stars, and black holes. For radii between $4\times10^2$ fm and $10^4$ fm the upper bound on the net charge is given by the universal relation $Z=0.71R_{fm}$, and for larger radii (measured in fm or km) $Z = 7 \times 10^{-5} R_{fm}^2 = 7 \times 10^{31} R_{km}^2$. For objects with nuclear density the relation corresponds to $Z \approx 0.7 A^{1/3}$ ($10^{8} < A < 10^{12}$) and $Z \approx 7\times10^{-5} A^{2/3}$ ($A > 10^{12}$), where $A$ is the baryon number. For some systems this universal upper bound improves existing charge limits in the literature.

description: This informative article delves into the multifaceted functions of sphincters in the human body. Acting as dynamic gatekeepers, sphincters are circular muscles strategically placed in various organs and systems to regulate the controlled flow of substances. The article explores the anatomy and different types of sphincters, ranging from muscular and smooth muscle sphincters to striated muscle sphincters, each serving unique roles. It delves into specific sphincters within the gastrointestinal, urinary, reproductive, cardiovascular, and respiratory systems, elucidating their roles in maintaining homeostasis. The article also addresses the crucial role of sphincters in preventing disorders and dysfunctions, emphasizing their significance in clinical interventions. By providing a comprehensive overview, this article serves as a valuable resource for understanding the intricate functions of sphincters in the human body.

description: The postburst object of a GRB is likely to be a highly magnetized, rapidly rotating compact object (e.g., a millisecond magnetar), which could produce an ultrarelativistic electron-positron-pair wind. The interaction of such a wind with an outwardly expanding fireball ejected during the burst leads to a relativistic wind bubble (RWB). We numerically calculate the dynamics and radiative properties of RWBs and use this model to explain the shallow decay phase of the early X-ray afterglows observed by Swift. We find that RWBs can fall into two types: forward-shock-dominated and reverse-shock-dominated bubbles. Their radiation during a period of $\sim 10^{2}-10^{5}$ seconds is dominated by the shocked medium and the shocked wind, respectively, based on different magnetic energy fractions of the shocked materials. For both types, the resulting light curves always have a shallow decay phase. In addition, we provide an example fit to the X-ray afterglows of GRB 060813 and GRB 060814 and show that they could be produced by forward-shock-dominated and reverse-shock-dominated bubbles, respectively. This implies that, for some early afterglows (e.g., GRB 060814), the long-lasting reverse shock emission is strong enough to explain their shallow decay phase.

description: Wireless indoor coverage and data capacity are important aspects of cellular networks. With the ever-increasing data traffic, demand for more data capacity indoors is also growing. The lower frequencies of the legacy frequency bands of macro outdoor cells manage to provide coverage inside buildings, however, new frequencies foreseen for the 5th generation (5G) of mobile communications in the millimeter wave (mmWave) spectrum penetrate very poorly into buildings. Therefore, a massive densification of the network would require to deploy a large number of indoor small cells, which would lead to high deployment costs to install the necessary wired/optical backhaul. Hence, other methods are needed that allow an increase of the data capacity indoors, bearing a lower cost than a fiber deployment. We propose a cost-efficient out-of-band repeater architecture that provides more data capacity indoors than an outdoor macro/micro network can provide to indoor, without adversely affecting a legacy network, and which readily works with the established cellular infrastructure as well as standard handsets/smartphones. This proposal is compared to conventional in- and out-of-band repeaters and relay nodes in order to highlight the advantages of our solution. While the data capacity for a single link is similar to that of repeaters and relays, a macro cell can be effectively offloaded. Cell capacities corresponding to at least 3--4 times that of a repeater or relay solution can be provided, depending on the number of parallel installed links and the bandwidth in the mmWave spectrum.

description: This paper provides details of the massless three-loop three-point integrals calculation at the symmetric point. Our work aimed to extend known two-loop results for such integrals to the three-loop level. Obtained results can find their application in regularization-invariant symmetric point momentum-subtraction (RI/SMOM) scheme QCD calculations of renormalization group functions and various composite operator matrix elements. To calculate integrals, we solve differential equations for auxiliary integrals by transforming the system to the $\varepsilon$-form. Calculated integrals are expressed through the basis of functions with uniform transcendental weight. We provide expansion up to the transcendental weight six for the basis functions in terms of harmonic polylogarithms with six-root of unity argument.

description: We investigate the asymptotic behavior for type II Hermite-Pade approximation to two functions, where each function has two branch points and the pairs of branch points are separated. We give a classification of the cases such that the limiting counting measures for the poles of the Hermite-Pade approximants are described by an algebraic function of order 3 and genus 0. This situation gives rise to a vector-potential equilibrium problem for three measures and the poles of the common denominator are asymptotically distributed like one of these measures. We also work out the strong asymptotics for the corresponding Hermite-Pade approximants by using a 3x3 Riemann-Hilbert problem that characterizes this Hermite-Pade approximation problem.
