High-Energy Astrophysics with Neutrino Telescopes
Creators: name: Chiarusi, T.
name: Spurio, M.
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Neutrino astrophysics offers new perspectives on the Universe investigation: high energy neutrinos, produced by the most energetic phenomena in our Galaxy and in the Universe, carry complementary (if not exclusive) information about the cosmos with respect to photons. While the small interaction cross section of neutrinos allows them to come from the core of astrophysical objects, it is also a drawback, as their detection requires a large target mass. This is why it is convenient put huge cosmic neutrino detectors in natural locations, like deep underwater or under-ice sites. In order to supply for such extremely hostile environmental conditions, new frontiers technologies are under development. The aim of this work is to review the motivations for high energy neutrino astrophysics, the present status of experimental results and the technologies used in underwater/ice Cherenkov experiments, with a special focus on the efforts for the construction of a km3 scale detector in the Mediterranean Sea.

Grazie a simulazioni numeriche relativistiche, un gruppo di scienziati ha per la prima volta dimostrato la relazione fra segnale gravitazionale emesso dalla fusione di due buchi neri di massa diversa e la forma del buco nero risultante. Il buco nero finale, simile a una castagna, produrrebbe picchi di frequenza multipli – i cosiddetti cinguettii – rilevabili se la linea di vista sul sistema è parallela al piano orbitale della fusione.

Linda Podio, ricercatrice dell'Inaf, ha guidato lo studio di un disco protoplanetario “giovane”, con un’età inferiore al milione di anni, posto quasi esattamente di taglio rispetto alla nostra linea di vista. Grazie a questa peculiare quanto fortuita configurazione, è stato possibile ottenere una sorta di tomografia della composizione chimica su tutto lo spessore del disco, evidenziando la presenza di metanolo, una delle più semplici molecole organiche complesse, i cosiddetti “mattoni” della vita, finora mai osservato in un disco così giovane

Sequence of phase transitions induced in an array of Josephson junctions by their crossover to pi-state
Creators: name: Korshunov, S. E.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: We show that the transition of Josephson junctions between the conventional and pi states caused by the decrease in temperature induces in a regular two-dimensional array of such junctions not just a single phase transition between two phases with different ordering but a sequence of two, three or four phase transitions. The corresponding phase diagrams are constructed for the cases of bipartite (square or honeycomb) and triangular lattices.

Orthomodular lattices, Foulis Semigroups and Dagger Kernel Categories
Creators: name: Jacobs, Bart
Publisher: name: arXiv

Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: This paper is a sequel to arXiv:0902.2355 and continues the study of quantum logic via dagger kernel categories. It develops the relation between these categories and both orthomodular lattices and Foulis semigroups. The relation between the latter two notions has been uncovered in the 1960s. The current categorical perspective gives a broader context and reconstructs this relationship between orthomodular lattices and Foulis semigroups as special instance.

L’analisi delle immagini dell’asteroide Bennu scattate dalla sonda spaziale Osiris-Rex della Nasa ha rivelato come questo corpo celeste presenti una superficie assai eterogenea. I ricercatori che hanno condotto le indagini, tra cui Maurizio Pajola dell’Inaf, hanno individuato una relazione complessa fra il modo in cui Bennu riflette la luce a diverse lunghezze d’onda, la morfologia della superficie e le sue alterazioni dovute al vento solare e al bombardamento da micrometeoriti
Cold Dark Matter from heavy Right-Handed neutrino mixing

Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We show that, within the see-saw mechanism, an almost decoupled RH neutrino species N_DM with mass M_DM \gtrsim 100 GeV can play the role of Dark Matter (DM). The N_DM's can be produced from non-adiabatic conversions of thermalized (source) RH neutrinos with mass M_S lower than M_DM. This is possible if a non-renormalizable operator is added to the minimal type I see-saw lagrangian. The observed DM abundance can be reproduced for M_DM δ^{1/4} \sim 10^-13 Λ_eff ξ, where Λ_eff is a very high energy new physics scale, δ\equiv (M_DM-M_S)/M_DM and ξ\lesssim 1 is a parameter determined by the RH neutrino couplings.

Rotationally invariant family of Lévy like random matrix ensembles
Creators: name: Choi, Jinmyung

Year: 2009
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We introduce a family of rotationally invariant random matrix ensembles characterized by a parameter $λ$. While $λ=1$ corresponds to well-known critical ensembles, we show that $λ\ne 1$ describes "Lévy like" ensembles, characterized by power law eigenvalue densities. For $λ> 1$ the density is bounded, as in Gaussian ensembles, but $λ<1$ describes ensembles characterized by densities with long tails. In particular, the model allows us to evaluate, in terms of a novel family of orthogonal polynomials, the eigenvalue correlations for Lévy like ensembles. These correlations differ qualitatively from those in either the Gaussian or the critical ensembles.

Venere va sulla Luna

Due astronomi dell’università di Yale hanno simulato impatti di meteoriti e comete su Venere ipotizzando che essa abbia avuto, in passato, oceani di acqua e un’atmosfera sottile come la Terra. La verifica di tale ipotesi, suffragata dallo studio della composizione chimica dell’attuale atmosfera, svelerebbe definitivamente il passato abitabile del pianeta. Secondo le simulazioni, la traiettoria di una considerevole quantità di materiale espulso in seguito agli impatti sarebbe arrivata sulla Luna, rimanendo pressoché inalterata nella composizione e sarebbe individuabile tuttora nelle rocce lunari.

title: Structural Identification and Damage Identification using Output-Only Vibration Measurements
Creators: name: Xing, Shutao
Publisher: name: Utah State University
Year: 2011

description: This dissertation studied the structural identification and damage detection of civil engineering structures. Several issues regarding structural health monitoring were addressed.
The data-driven subspace identification algorithm was investigated for modal identification of bridges using output-only data. This algorithm was tested through a numerical truss bridge with abrupt damage as well as a real concrete highway bridge with actual measurements. Stabilization diagrams were used to analyze the identified results and determine the modal characteristics. The identification results showed that this identification method is quite effective and accurate.
The influence of temperature fluctuation on the frequencies of a highway concrete bridge was investigated using ambient vibration data over a one-year period of a highway bridge under health monitoring. The data were fitted by nonlinear and linear regression models, which were then analyzed.
The substructure identification by using an adaptive Kalman filter was investigated by applying numerical studies of a shear building, a frame structure, and a truss structure. The stiffness and damping were identified successfully from limited acceleration responses, while the abrupt damages were identified as well. Wavelet analysis was also proposed for damage detection of substructures, and was shown to be able to approximately locate such damages.
Delamination detection of concrete slabs by modal identification from the output-only data was proposed and carried out through numerical studies and experimental modal testing. It was concluded that the changes in modal characteristics can indicate the presence and severity of delamination. Finite element models of concrete decks with different delamination sizes and locations were established and proven to be reasonable.
Pounding identification can provide useful early warning information regarding the potential damage of structures. This thesis proposed to use wavelet scalograms of dynamic response to identify the occurrence of pounding. Its applications in a numerical example as well as shaking table tests of a bridge showed that the scalograms can detect the occurrence of pounding very well.
These studies are very useful for vibration-based structural health monitoring.

A dielectric properties of natural and synthetic rubber-sulphur compounds
Creators: name: Codrington, Robert Smith
Publisher: name: University of British Columbia
Year: 2012

description: The dielectric properties of natural and butyl rubber-sulphur compounds have been investigated at temperatures of 20°C and 60°C and extensions of 0% and 200%, in a frequency range extending from 100 cycles to 20 megacycles. This investigation has shown that the dielectric constant of butyl rubber is less than that of natural rubber and that the dielectric constants of both types of rubber decrease with increasing temperature and increasing extension. The investigation has also shown that the dielectric behaviour of these rubbers may be explained by the Gevers' extension of the Debye dipole theory. If free sulphur is present in the rubbers, the behaviour must be explained by a combination of the dipole theory and the inhomogeneity theory. The Kirkwood-Fuoss theory for polar polymers, has been applied to natural rubber with 2% sulphur. The dipole moment per monomer unit obtained from the Kirkwood-Fuoss plot for this sample was 0.41 Debye units.

Il sublime Arrokoth

Arrokoth, noto anche come Ultima Thule – il primitivo oggetto transnettuniano che la sonda spaziale New Horizons della Nasa ha sorvolato per la prima volta il primo dell'anno del 2019 – potrebbe aver cambiato la sua forma in modo significativo nei primi 100 milioni di anni dalla sua formazione. A dirlo è uno studio condotto da un gruppo di ricercatori guidati dall'Accademia Cinese delle Scienze e dal Max Planck Institute for Solar System Research. Lo studio suggerisce inoltre che l'attuale forma di Arrokoth, simile a quella di un pupazzo di neve appiattito, potrebbe essere dovuta a un degassamento di composti volatili indotto dalla sublimazione.

description: In the pseudogap state of the high-Tc copper-oxide (cuprate) superconductors, angle-resolved photoemission (ARPES) measurements have seen an Fermi arc, i.e., an open-ended gapless section in the large Fermi surface, rather than a closed loop expected of an ordinary metal. This is all the more puzzling because Fermi pockets (small closed Fermi surface features) have been suggested from recent quantum oscillation measurements. The Fermi arcs have worried the high-Tc community for many years because they cannot be understood in terms of existing theories. Theorists came up with a way out in the form of conventional Fermi surface pockets associated with competing order, with a back side that is for detailed reasons invisible by photoemission. Here we report ARPES measurements of La-Bi2201 that give direct evidence of the Fermi pocket. The charge carriers in the pocket are holes and the pockets show an unusual dependence upon doping, namely, they exist in underdoped but not overdoped samples. A big surprise is that these Fermi pockets appear to coexist with the Fermi arcs. This coexistence has not been expected theoretically and the understanding of the mysterious pseudogap state in the high-Tc cuprate superconductors will rely critically on understanding such a new finding.

description: We explore the phase diagram and the critical behavior of QCD thermodynamic quantities in the context of the so-called Polyakov--Nambu--Jona-Lasinio model. We show that this improved field theoretical model is a successful candidate for studying the equation of state and the critical behavior around the critical end point. We argue that a convenient choice of the model parameters is crucial to get the correct description of isentropic trajectories. The effects of the regularization procedure in several thermodynamic quantities is also analyzed. The results are compared with simple thermodynamic expectations and lattice data.

Alcuni astronomi della University of Western Australia e dell’Icrar hanno sviluppato un nuovo modo di studiare la formazione stellare nelle galassie, dall'alba dei tempi a oggi. In particolare, hanno considerato la variazione nel tempo del contenuto di elementi chimici pesanti – i metalli – prodotti durante l’evoluzione stellare. La nuova tecnica, applicata a circa 7000 galassie vicine, ha consentito di ricostruire la storia di formazione stellare delle galassie e del cosmo, rivelando che l’universo ha formato la maggior parte delle stelle nei primi 4 miliardi di anni dopo il Big Bang.

Existence and stability of multisite breathers in honeycomb and hexagonal lattices

description: We study the existence and stability of multisite discrete breathers in two prototypical non-square Klein-Gordon lattices, namely a honeycomb and a hexagonal one. In the honeycomb case we consider six-site configurations and find that for soft potential and positive coupling the out-of-phase breather configuration and the charge-two vortex breather are linearly stable, while the in-phase and charge-one vortex states are unstable. In the hexagonal lattice, we first consider three-site configurations. In the case of soft potential and positive coupling, the in-phase configuration is unstable and the charge-one vortex is linearly stable. The out-of-phase configuration here is found to always be linearly unstable. We then turn to six-site configurations in the hexagonal lattice. The stability results in this case are the same as in the six-site configurations in the honeycomb lattice. For all configurations in both lattices, the stability results are reversed in the setting of either hard potential or negative coupling. The study is complemented by numerical simulations which are in very good agreement with the theoretical predictions. Since neither the form of the on-site potential nor the sign of the coupling parameter involved have been prescribed, this description can accommodate inverse-dispersive systems (e.g., supporting backward waves) such as transverse dust-lattice oscillations in dusty plasma (Debye) crystals or analogous modes in molecular chains.

Reaction of Accretion Disks to Abrupt Mass Loss During Binary Black Hole Merger

description: The association of an electromagnetic signal with the merger of a pair of supermassive black holes would have many important implications. For example, it would provide new information about gas and magnetic field interactions in dynamical spacetimes as well as a combination of redshift and luminosity distance that would enable precise cosmological tests. A proposal first made by Bode & Phinney (2007) is that because radiation of gravitational waves during the final inspiral and merger of the holes is abrupt and decreases the mass of the central object by a few percent, there will be waves in the disk that can steepen into shocks and thus increase the disk luminosity in a characteristic way. We evaluate this process analytically and numerically. We find that shocks only occur when the fractional mass loss exceeds the half-thickness (h/r) of the disk, hence significant energy release only occurs for geometrically thin disks which are thus at low Eddington ratios. This strongly limits the effective energy release, and in fact our simulations show that the natural variations in disk luminosity are likely to obscure this effect entirely. However, we demonstrate that the reduction of luminosity caused by the retreat of the inner edge of the disk following mass loss is potentially detectable. This decrease occurs even if the disk is geometrically thick, and lasts for a duration on the order of the viscous time of the modified disk. Observationally, the best prospect for detection would be a sensitive future X-ray instrument with a field of view of on the order of a square degree, or possibly a wide-field radio array such as the Square Kilometer Array, if the disk changes produce or interrupt radio emission from a jet.

title: Asymptotic Multiphysics Modeling of Composite Beams
Creators: name: Wang, Qi

description: A series of composite beam models are constructed for efficient high-fidelity beam analysis based on the variational-asymptotic method (VAM). Without invoking any a priori kinematic assumptions, the original three-dimensional, geometrically nonlinear beam problem is rigorously split into a two-dimensional cross-sectional analysis and a one-dimensional global beam analysis, taking advantage of the geometric small parameter that is an inherent property of the structure.
The thermal problem of composite beams is studied first. According to the quasisteady theory of thermoelasticity, two beam models are proposed: one for heat conduction analysis and the other for thermoelastic analysis. For heat conduction analysis, two different types of thermal loads are modeled: with and without prescribed temperatures over the crosssections. Then a thermoelastic beam model is constructed under the previously solved thermal field. This model is also extended for composite materials, which removed the restriction on temperature variations and added the dependence of material properties with respect to temperature based on Kovalenoko’s small-strain thermoelasticity theory.
Next the VAM is applied to model the multiphysics behavior of beam structure. A multiphysics beam model is proposed to capture the piezoelectric, piezomagnetic, pyroelectric, pyromagnetic, and hygrothermal effects. For the zeroth-order approximation, the classical models are in the form of Euler-Bernoulli beam theory. In the refined theory, generalized Timoshenko models have been developed, including two transverse shear strain measures. In order to avoid ill-conditioned matrices, a scaling method for multiphysics modeling is also presented. Three-dimensional field quantities are recovered from the one-dimensional variables obtained from the global beam analysis.
A number of numerical examples of different beams are given to demonstrate the application and accuracy of the present theory. Excellent agreements between the results obtained by the current models and those obtained by three-dimensional finite element analysis, analytical solutions, and those available in the literature can be observed for all the cross-sectional variables. The present beam theory has been implemented into the computer program VABS (Variational Asymptotic Beam Sectional Analysis).

description: The Small Ball Inequality is a conjectural lower bound on sums the L-infinity norm of sums of Haar functions supported on dyadic rectangles of a fixed volume in the unit cube. The conjecture is fundamental to questions in discrepancy theory, approximation theory and probability theory. In this article, we concentrate on a special case of the conjecture, and give the best known lower bound in dimension 3, using a conditional expectation argument.
