description: One of the primary means of sea exploration is autonomous underwater vehicles (AUVs). To perform these tasks, AUVs must navigate the rough challenging sea environment. AUVs usually employ an inertial navigation system (INS), aided by a Doppler velocity log (DVL), to provide the required navigation accuracy. The DVL transmits four acoustic beams to the seafloor, and by measuring changes in the frequency of the returning beams, the DVL can estimate the AUV velocity vector. However, in practical scenarios, not all the beams are successfully reflected. When only three beams are available, the accuracy of the velocity vector is degraded. When fewer than three beams are reflected, the DVL cannot estimate the AUV velocity vector. This paper presents a data-driven approach, MissBeamNet, to regress the missing beams in partial DVL beam measurement cases. To that end, a deep neural network (DNN) model is designed to process the available beams along with past DVL measurements to regress the missing beams. The AUV velocity vector is estimated using the available measured and regressed beams. To validate the proposed approach, sea experiments were made with the "Snapir" AUV, resulting in an 11 hours dataset of DVL measurements. Our results show that the proposed system can accurately estimate velocity vectors in situations of missing beam measurements. Our dataset and codebase implementing the described framework is available at our GitHub repository https://github.com/ansfl/MissBeamNet .

Dynamical effects of self-generated magnetic fields in cosmic ray modified shocks

description: Recent observations of greatly amplified magnetic fields ($δB/B\sim 100$) around supernova shocks are consistent with the predictions of the non-linear theory of particle acceleration (NLT), if the field is generated upstream of the shock by cosmic ray induced streaming instability. The high acceleration efficiencies and large shock modifications predicted by NLT need however to be mitigated to confront observations, and this is usually assumed to be accomplished by some form of turbulent heating. We show here that magnetic fields with the strength inferred from observations have an important dynamical role on the shock, and imply a shock modification substantially reduced with respect to the naive unmagnetized case. The effect appears as soon as the pressure in the turbulent magnetic field becomes comparable with the pressure of the thermal gas. The relative importance of this unavoidable effect and of the poorly known turbulent heating is assessed. More specifically we conclude that even in the cases in which turbulent heating may be of some importance, the dynamical reaction of the field cannot be neglected, as instead is usually done in most current calculations.

description: The intrinsic alignments of galaxies, i.e., the correlation between galaxy shapes and their environment, are a major source of contamination for weak gravitational lensing surveys. Most studies of intrinsic alignments have so far focused on measuring and modelling the correlations of luminous red galaxies with galaxy positions or the filaments of the cosmic web. In this work, we investigate alignments around cosmic voids. We measure the intrinsic alignments of luminous red galaxies detected by the Sloan Digital Sky Survey around a sample of voids constructed from those same tracers and with radii in the ranges: $[20-30; 30-40; 40-50]$ $h^{-1}$ Mpc and in the redshift range $z=0.4-0.8$. We present fits to the measurements based on a linear model at large scales, and on a new model based on the void density profile inside the void and in its neighbourhood. We constrain the free scaling amplitude of our model at small scales, finding no significant alignment at $1σ$ for either sample. We observe a deviation from the null hypothesis, at large scales, of 2$σ$ for voids with radii between 20 and 30 $h^{-1}$ Mpc, and 1.5 $σ$ for voids with radii between 30 and 40 $h^{-1}$ Mpc and constrain the amplitude of the model on these scales. We find no significant deviation at 1$σ$ for larger voids. Our work is a first attempt at detecting intrinsic alignments of galaxy shapes around voids and provides a useful framework for their mitigation in future void lensing studies.

description: The modeling and identification of time series data with a long memory are important in various fields. The streamflow discharge is one such example that can be reasonably described as an aggregated stochastic process of randomized affine processes where the probability measure, we call it reversion measure, for the randomization is not directly observable. Accurate identification of the reversion measure is critical because of its omnipresence in the aggregated stochastic process. However, the modeling accuracy is commonly limited by the available real-world data. One approach to this issue is to evaluate the upper and lower bounds of a statistic of interest subject to ambiguity of the reversion measure. Here, we use the Tsallis Value-at-Risk (TsVaR) as a convex risk measure to generalize the widely used entropic Value-at-Risk (EVaR) as a sharp statistical indicator. We demonstrate that the EVaR cannot be used for evaluating key statistics, such as mean and variance, of the streamflow discharge due to the blowup of some exponential integrand. In contrast, the TsVaR avoids this issue because it requires only the existence of some polynomial, not exponential moment. As a demonstration, we apply the semi-implicit gradient descent method to calculate the TsVaR and corresponding Radon-Nikodym derivative for time series data of actual streamflow discharges in mountainous river environments.

description: We study the polarization dynamics of ultrafast solitons in mode-locked fiber lasers. We find that when a stable soliton is generated, it's state-of-polarization shifts toward a stable state and when the soliton is generated with excess power levels it experiences relaxation oscillations in its intensity and timing. On the other hand, when a soliton is generated in an unstable state-of-polarization, it either decays in intensity until it disappears, or its temporal width decreases until it explodes into several solitons and then it disappears. We also found that when two solitons are simultaneously generated close to each other, they attract each other until they collide and merge into a single soliton. Although, these two solitons are generated with different states-of-polarization, they shift their state-of-polarization closer to each other until the polarization coincides when they collide. We support our findings by numerical calculations of a non-Lagrangian approach by simulating the Ginzburg-Landau equation governing the dynamics of solitons in a laser cavity. Our model also predicts the relaxation oscillations of stable solitons and the two types of unstable solitons observed in the experimental measurements.

description: Closed shell molecular structures are under normal conditions time-reversal invariant. Experimental evidences point, however, towards that this invariance may be locally violated when the structure is in contact with a particle reservoir. The mechanisms behind such local symmetry breaking are not clear by any means. By considering a minimal model for a closed shell structure, here we propose that the symmetry breaking may result from a combination of internal and/or external interactions. It is shown that a magnetic moment of a localized electron level can be generated and maintained under the influence of such combination. The theoretical results should cast new light on the mechanisms that may form magnetic properties in molecular compounds.

description: We propose a new approach, based on the Hanbury Brown and Twiss intensity interferometry, to transform a Cherenkov telescope to its equivalent optical telescope. We show that, based on the use of photonics components borrowed from quantum-optical applications, we can recover spatial details of the observed source down to the diffraction limit of the Cherenkov telescope, set by its diameter at the mean wavelength of observation. For this, we propose to apply aperture synthesis techniques from pairwise and triple correlation of sub-pupil intensities, in order to reconstruct the image of a celestial source from its Fourier moduli and phase information, despite atmospheric turbulence. We examine the sensitivity of the method, i.e. limiting magnitude, and its implementation on existing or future high energy arrays of Cherenkov telescopes. We show that despite its poor optical quality compared to extremely large optical telescopes under construction, a Cherenkov telescope can provide diffraction limited imaging of celestial sources, in particular at the visible, down to violet wavelengths.

description: Foreign immigration in Perugia. Outline concerning quantitative and distributional data, and some critical aspects
Foreign immigration in Umbria is a structural growing phenomenon. The region
is the second one in Italy in percentage terms of foreigners on the total population.
This paper looks over in particular the question of foreign immigration in
Perugia, in the light of recent data processed with a method providing a sufficiently clear picture of the distribution of immigrants in the historic center and suburbs. The attention is also drawn to the critical aspects of integration (related to the employment status, housing and education) and to the projects implemented by local institutions and associations aimed to promote the integration of immigrants into the social context of Umbria and Perugia.

Immigration étrangère à Pérouse. Analyse du phénomène du point de vue de la dimension numérique et de la distribution sur le territoire.
Un bref aperçu de quelques difficultés qui en dérivent On peut considérer désormais l’immigration étrangère en Ombrie comme un phénomène structural qui va augmenter chaque année. Cette région se situe en effet au second rang en Italie si l’on considère l’incidence du nombre des étrangers sur le total de la population. L’auteur fixe son attention en particulier sur la population immigrée vivant à Pérouse. Il s’appuie sur un travail paru récemment fournissant une image assez nette de la situation actuelle par rapport à la distribution des immigrés dans le centre historique et dans la banlieu de la commune. On envisage même les aspects critiques liés à l’intégration (par rapport,
en particulier, au travail, au logement et à l’instruction) et on relate
quelques projets des organismes locaux et des associations. Ils travaillent ensemble en effet dans le but d’encourager l’intégration des immigrés dans le tissu social de l’Ombrie et de Pérouse.

description: We present a vacuum of heterotic M-theory whose observable sector has the MSSM spectrum with the addition of one extra pair of Higgs-Higgs conjugate superfields. The quarks/leptons have a realistic mass hierarchy with a naturally light first family. The double elliptic structure of the Calabi-Yau compactification threefold leads to two ``stringy'' selection rules. These classically disallow Yukawa couplings to the second Higgs pair and, hence, Higgs mediated flavor-changing neutral currents. Such currents are induced in higher-dimensional interactions, but are naturally suppressed. We show that our results fit comfortably below the observed upper bounds on neutral flavor-changing processes.

description: In the dense-neutrino region above the neutrino sphere of a supernova (r > 400 km), neutrino-neutrino refraction causes collective flavor transformations. They can lead to "spectral splits" where an energy E_split splits the transformed spectrum sharply into parts of almost pure but different flavors. Unless there is an ordinary MSW resonance in the dense-neutrino region, E_split is determined by flavor-lepton number conservation alone. Spectral splits are created by an adiabatic transition between regions of large and small neutrino density. We solve the equations of motion in the adiabatic limit explicitly and provide analytic expressions for a generic example.

description: Interference tests are used in shale reservoirs to evaluate the strength of connectivity between wells. The results inform engineering decisions about well spacing. In this paper, we propose a new procedure for interpreting interference tests. We fit the initial interference response with the solution to the 1D diffusivity equation at an offset observation point. It is advantageous to use the initial interference response, rather than the subsequent trend, because it is less affected by nonlinearities, time-varying boundary conditions, and uncertainties about flow geometry and regime. From the curve fit, we estimate the hydraulic diffusivity and conductivity of the fractures connecting the wells. For engineering purposes, it would be useful to quantify the impact of interference on well production. Thus, we seek a relationship between the degree of production interference (DPI) and an appropriate dimensionless quantity that can be derived from the estimate of fracture conductivity. Using simulations run under a wide range of conditions, we find that the classical definition for dimensionless fracture conductivity does not achieve a consistent prediction of DPI. This occurs because the dimensionless fracture conductivity is derived assuming radial flow geometry, but the dominant flow geometry during shale production is linear. We also find that the CPG (Chow Pressure Group) metric does not yield consistently accurate predictions of DPI. As an alternative, we derive a dimensionless quantity similar to the classical dimensionless fracture conductivity, but derived for linear, flow geometry. Using this approach, we calculate a dimensionless interference length that collapses all cases onto a single curve that predicts DPI as a function of fracture conductivity, well spacing, and formation properties. We conclude by applying the new method to field cases from the Anadarko and Delaware Basins.
Uniform observability of hidden Markov models and filter stability for unstable signals

description: A hidden Markov model is called observable if distinct initial laws give rise to distinct laws of the observation process. Observability implies stability of the nonlinear filter when the signal process is tight, but this need not be the case when the signal process is unstable. This paper introduces a stronger notion of uniform observability which guarantees stability of the nonlinear filter in the absence of stability assumptions on the signal. By developing certain uniform approximation properties of convolution operators, we subsequently demonstrate that the uniform observability condition is satisfied for various classes of filtering models with white-noise type observations. This includes the case of observable linear Gaussian filtering models, so that standard results on stability of the Kalman--Bucy filter are obtained as a special case.

description: A journey, a long journey migrants have to travel - without end; it winds in many directions, inward and outward, material and spiritual, by sea and in their souls. A soul divided between the urge to undertake the journey and the need to find rest at home. Must they accept their destiny or look for a new one? Migrants feel the need to maintain connections with their home country, at the same time, they want to build a home in their new land.
What is the role of Public Television in this context, with an audience
composed of migrants of second, third or even fourth generation?
Without doubt, it is a very complex role that, through articulated programming based on information, culture, and entertainment, guides
them through that long and difficult journey. This must be built upon a positive relationship and constant attention to every feedback, expressed or not expressed, that requires expert professional care and - in steady connection with the life of our migrants - the ability to look beyond the border.

C’est un voyage. Un long voyage – un voyage sans fin - celui que les
émigrants sont appelés à faire.
Il se déroule sur une double voie, une voie interne et une autre externe.
Une voie matérielle et une autre spirituelle, maritime et mentale. L’émigrant vit en perpétuelle dichotomie, pris entre le besoin de partir et
celui de s’enraciner, d’accepter son propre destin ou de s’en chercher un
autre, entre le besoin de maintenir des liens avec son pays d’origine et la
nécessité de se construire une nouvelle territorialité dans le pays d’accueil. Dans ce cadre de référence, pour nos compatriotes émigrés de la première, deuxième, troisième et quatrième génération qui vivent à  ’étranger, quelle est la mission de la télévision publique, de Rai International? Une mission d’accompagnement dans leur double voyage intérieur et matériel assurément complexe réalisée grâce à une programmation variée faite d’informations, d’approfondissements et d’entretiens.

description: As the superior improvement on wireless network coverage, spectrum efficiency and energy efficiency, Intelligent reflecting surface (IRS) has received more and more attention. In this work, we consider a large-scale IRS-assisted heterogeneous cellular network (HCN) consisting of $K$ ($K \geq 2$) tiers of base stations (BSs) and one tier of passive IRSs. With tools from stochastic geometry, we analyze the coverage probability and network spatial throughput of the downlink IRS-assisted $K$-tier HCN. Compared with the conventional HCN, we observe the significant gain achieved by IRSs in coverage probability and network spatial throughput. The proposed analytical framework can be used to understand the limit of gain achieved by IRSs in HCN.

description: We develop a hydrodynamic theory for an electron system exhibiting the anomalous Hall effect, and show that an additional anomalous Hall effect is induced by a vorticity generated near boundaries. We calculate the momentum flux and force proportional to the electric field using linear response theory. The hydrodynamic equation is obtained by replacing the local electric field with the electric current, focusing on a scale that is sufficiently larger than the mean free path. It is demonstrated that there is a coupling between a vorticity of an electric current and a magnetization which generates a pressure from non-uniform vorticity. Taking into account Hall viscosity and relaxation forces, a non-uniform flow near a boundary and an additional Hall force are calculated. The additional anomalous Hall force is opposite to conventional anomalous Hall force, resulting in a sign reversal in thin systems.

Movements, chamber orchestra Three movements for wind ensemble
Creators: name: Trew, Michael Russell
Publisher: name: University of British Columbia
Year: 2010

description: Three Movements for Wind Ensemble, a 13-minute work for a wind ensemble consisting of twenty-five instruments, was composed in Vancouver between 1984-86. The first and third movements of this work are reminiscent stylistically of the Neo-classical tradition, while the second is a passacaglia involving a tonal ostinato juxtaposed with atonal ideas. Ideas, both thematic and structural, while entirely original, except for a 6-bar sequence in measures 59-64 of movement 1, were influenced by specific works of several composers. Stylistically, the composition is tonal, and reflects my background in jazz composition as well as my classical training. Chords are frequently characterized by the use of major second configurations, and melodies are derived from numerous sources. The music of Bach, Stravinsky, and Ives exert strong influences on the work. The work is difficult to categorize structurally, because the first and third movements are not traditional forms. I feel that the piece might appeal to both gifted and average listeners. The individual parts are not complex or difficult to perform, but the resulting ensemble yields an overall complexity.

description: Extensions of the gravitational framework of Brans-Dicke (BD) are studied by considering two different scenarios: i) `BD-$Λ$CDM', in which a rigid cosmological constant, $Λ$, is included, thus constituting a BD version of the vanilla concordance $Λ$CDM model (the current standard model of cosmology with flat three-dimensional geometry), and ii) `BD-RVM', a generalization of i) in which the vacuum energy density (VED), $ρ_{\textrm{vac}}$, is a running quantity evolving with the square of the Hubble rate: $δρ_{\textrm{vac}}(H)\propto ν\, m^2_{\textrm{Pl}} (H^2-H_0^2)$ (with $|ν|\ll 1$). This dynamical scenario is motivated by recent studies of quantum field theory (QFT) in curved spacetime, which lead to the running vacuum model (RVM). We solve the background as well as the perturbation equations for each cosmological model and test their performance against the modern wealth of cosmological data, namely a compilation of the latest SNIa+$H(z)$+BAO+LSS+CMB observations. We utilize the AIC and DIC statistical information criteria in order to determine if they can fit better the observations than the concordance model. The two BD extensions are tested by considering three different datasets. According to the AIC and DIC criteria, both BD extensions i) and ii) are competitive, but the second one (the BD-RVM scenario) is particularly favored when it is compared with the vanilla model. This fact may indicate that the current observations favor a mild dynamical evolution of the Newtonian coupling $G_N$ as well as of the VED. This is in agreement with recent studies suggesting that the combination of these two features can be favorable for a possible resolution of the $σ_8$ and $H_0$ tensions. In this work, we show that the Brans-Dicke theory with running vacuum has the potential to alleviate the two tensions at the same time.

description: We define and sketch the generalized ergosphere of the Majumdar-Papapetrou (MP) spacetime. In particular, we demonstrate the existence of closed orbits of negative energy that live outside the event horizon of such a spacetime. Relying on the Penrose process mechanism, we use these orbits to illustrate the possibility of energy extraction from a MP binary black hole by particle scattering. We also analyze the efficiency of the process, and construct explicit examples that optimize the extraction of energy. Lastly, we show how such concepts can be extended to a pair of non-coalescing Kerr black holes described by the Cabrera-Munguia, Manko and Ruiz (CMMR) metric.

description: We present a method for the direct and continuous separation of red and white blood cells from plasma at the microscale. The method is implemented in a microfluidic system with magnetic functionality. The fluidic structure within the microsystem consists of an inlet and a single microfluidic channel with multiple outlets. The magnetic functionality is provided by an array of integrated soft-magnetic elements that are embedded transverse and adjacent to the microchannel. The elements are magnetized using an external field, and once magnetized they produce a magnetic force on blood cells as they flow through the microchannel. In whole blood, white blood cells (WBCs) behave as diamagnetic microparticles, while red blood cells (RBCs) exhibit diamagnetic or paramagnetic behavior depending on the oxygenation of their hemoglobin. We study the motion of blood cells through the microchannel using a mathematical model that takes into account the magnetic, fluidic and gravitational forces on the cells. We use the model to study blood cell separation, and our analysis indicates that the microsystem is capable of separating WBC-rich plasma, deoxygenated RBC-rich plasma and cell-depleted plasma into respective outlets.

description: We represent a class of new Gravastar solutions as obtained by Mazur and Mottola in a gravitational Bose-Einstein condensate (GBEC) in a cylindrical symmetric space-time. A stable gravastar with three distinct regions namely, (i) Interior de-Sitter space, (ii) Intermediate thin shell with a slice of finite length and (iii) exterior vacuum region. The interior region is characterised by positive energy density and negative pressure $(p=-ρ)$, which exerts a repulsive outward force at all points on the thin shell. The thin shell separating the interior and exterior is supposed to be consisting of ultra-relativistic stiff fluid having equation of state $p=ρ$, which satisfies the Zel'dovich's criteria. This thin shell, which is considered as the critical surface for the quantum phase transition, replaces both the classical de-Sitter and Schwarzschild event horizons. The new solution is free from any singularities as well as any information paradox. The energy density, total energy, proper length, mass and entropy of the shell region are explored in this model and the gravastar model is stable and physically viable.

description: Pollenza, l’antica Montemilone, pregevole centro storico sulla media
valle del Chienti, in provincia di Macerata, ha ospitato, dall’11 al 13 luglio
2008, il “IV Convegno Internazionale sui Beni Culturali Territoriali”,
organizzato dal Prof. Peris Persi e dall’Istituto di Geografia dell’Università
degli Studi di Urbino.
Rispetto ai precedenti incontri – dedicati nell’ordine a Siti, ville e sedi
rurali di residenza, culto e lavoro (Urbino 2001); Ville e grandi residenze
gentilizie di campagna tra sviluppo regionale e identità locale (Treia
2003); Paesaggio e altri beni territoriali. Segni, sogni e bisogni delle popolazioni locali tra ricerca e governance (Urbino 2006) – il quarto appuntamento è stato incentrato sull’analisi delle problematiche territoriali
legate ai “beni” della cultura, dei luoghi e delle identità locali. Per portare
ai migliori risultati un progetto tanto impegnativo si è ritenuta fondamentale la collaborazione di territorialisti e amministratori, impegnati assieme ai geografi, a confrontarsi sullo sviluppo sociale ed economico,
filtrato e guidato proprio dai valori intangibili del paesaggio.

Improved dispersion relations for γγ\to π^0π^0

description: We perform a dispersive theoretical study of the reaction γγ\to pi^0π^0 emphasizing the low energy region. The large source of theoretical uncertainty to calculate the γγ\toπ^0π^0 total cross section for \sqrt{s}\gtrsim 0.5 GeV within the dispersive approach is removed. This is accomplished by taking one more subtraction in the dispersion relations, where the extra subtraction constant is fixed by considering new low energy constraints, one of them further refined by taking into consideration the f_0(980) region. This allows us to make sharper predictions for the cross section for \sqrt{s}\lesssim 0.8 GeV, below the onset of D-wave contributions. In this way, were new more precise data on γγ\toπ^0π^0 available one might then distinguish between different parameterizations of the ππisoscalar S-wave. We also elaborate on the width of the σresonance to γγand provide new values.

description: Si è svolto a Roma, nell’Aula “Giuseppe Dalla Vedova” di Palazzetto
Mattei in Villa Celimontana presso la Società Geografica Italiana, il 30
giugno 2008, un dibattito sul tema “Valutazione delle ricadute territoriali
dei progetti turistici”, in occasione della presentazione del volume curato
da G. Faggiani, G. Imbesi, G. Morabito e G. Vaccaro, dal titolo “Trasformazioni territoriali e progettualità turistica” edito da Gangemi.
Alla presenza di un pubblico di esperti del settore, il Presidente Prof. F.
Salvatori ha ringraziato le autorità presenti e ha introdotto la discussione
evidenziando l’importanza che il turismo riveste in Italia, quale fenomeno
economicamente molto importante e in grande espansione.
Secondo le statistiche si tratta di uno dei primi settori di attività a livello
mondiale, che sostiene l’8% dell’export complessivo, che ha un grande
peso nella formazione del PIL di molti Paesi e che ne coinvolge un numero
crescente, sia dal lato dell’offerta che della domanda; dunque un
comparto di grande importanza e di significativo impatto, se non adeguatamente pianificato, sul territorio.

description: This work studies the estimation of many statistical quantiles under differential privacy. More precisely, given a distribution and access to i.i.d. samples from it, we study the estimation of the inverse of its cumulative distribution function (the quantile function) at specific points. For instance, this task is of key importance in private data generation. We present two different approaches. The first one consists in privately estimating the empirical quantiles of the samples and using this result as an estimator of the quantiles of the distribution. In particular, we study the statistical properties of the recently published algorithm introduced by Kaplan et al. 2022 that privately estimates the quantiles recursively. The second approach is to use techniques of density estimation in order to uniformly estimate the quantile function on an interval. In particular, we show that there is a tradeoff between the two methods. When we want to estimate many quantiles, it is better to estimate the density rather than estimating the quantile function at specific points.
