description: Light shining through wall experiments (in the optical as well as in the microwave regime) are a powerful tool to search for light particles coupled very weakly to photons such as axions or extra hidden sector photons. Resonant regeneration, where a resonant cavity is employed to enhance the regeneration rate of photons, is one of the most promising techniques to improve the sensitivity of the next generation of experiments. However, doubts have been voiced if such methods work at very low regeneration rates where on average the cavity contains less than one photon. In this note we report on a demonstration experiment using a microwave cavity driven with extremely low power, to show that resonant amplification works also in this regime. In accordance with standard quantum mechanics this is a demonstration that interference also works at the level of less than one quantum. As an additional benefit this experiment shows that thermal photons inside the cavity cause no adverse effects.

Two-neutron overlap functions for 6He from a microscopic structure model

description: A fully antisymmetrized microscopic model is developed for light two-neutron halo nuclei using a hyper-spherical basis to describe halo regions. The many-body wavefunction is optimized variationally. The model is applied to 6He bound by semi realistic Minnesota nucleon-nucleon forces. The two-neutron separation energy and the radius of the halo are reproduced in agreement with experiment. Antisymmetrization effects between 4He and halo neutrons are found to be crucial for binding of 6He. We also properly extract two-neutron overlap functions and find that there is a significant increase of 30%-70% in their normalization due to microscopic effects as compared to the results of three-body models.

description: We propose a counting dimension for subsets of Z and prove that, under certain conditions on two such subsets E and F, for Lebesgue almost every real λ the counting dimension of E+[λF] is at least the minimum between 1 and the sum of the counting dimensions of E and F. Furthermore, if the sum of the counting dimensions of E and F is larger than 1, then E+[λF] has positive upper Banach density for Lebesgue almost every λ. The result has direct consequences when E,F are arithmetic sets, e.g. the integer values of a polynomial with integer coefficients.

description: We extend the Atiyah, Patodi, and Singer index theorem for first order differential operators from the context of manifolds with cylindrical ends to manifolds with periodic ends. This theorem provides a natural complement to Taubes' Fredholm theory for general end-periodic operators. Our index theorem is expressed in terms of a new periodic eta-invariant that equals the Atiyah-Patodi-Singer eta-invariant in the cylindrical setting. We apply this periodic eta-invariant to the study of moduli spaces of Riemannian metrics of positive scalar curvature.

Coded caching : convex optimization and graph theoretical perspectives
Creators: name: Saberali, Seyed Ali
Publisher: name: University of British Columbia
Year: 2020

description: Data communications is an essential building block of everyday life. A fundamental challenge in communications networks has always been the limited capacity of the links that transfer data from sources to destinations. A core technique to alleviate the load on the network links is to cache popular content in intermediate nodes between the sources and destinations to avoid redundant transmission of the same data. Although the concept of caching has been well studied in the context of computer networks, new settings are emerging in communication networks for which the conventional caching techniques are significantly inefficient and deliver far less than the full benefits that caching can provide. One such setting is that of networks in which caches are connected to the backbone communications system through broadcast links. In the recent years, substantial amount of work has been devoted to characterizing the fundamental limits of the gain of caching in such networks, and coming up with techniques to achieve those limits. At the center of these attempts has been the introduction of coded caching, a technique rooted in information theory that takes advantage of network coding to minimize the amount of information that needs to be communicated in the network. This thesis is devoted to the development of coded caching techniques for three specific settings that are of significant practical interest. In particular, it adapts a convex optimization perspective to address the problem of caching in the presence of duplicate demands, and the problem of designing the optimal way to place the content in caches when different files are non-uniformly popular. The latter is a core problem in the caching literature, for which we derive the optimal placement scheme for certain settings of the problem. We further look into the problem of placement of files in caches without splitting them into sub-packets. We establish a graph theoretical model to study this problem and explore the efficiency of coded caching under this constraint. We believe that this thesis provides fundamental insights into these problems and solutions for them.
Gravitational lensing of the cosmic microwave background by nonlinear structures

description: Weak gravitational lensing changes the angular power spectra of the cosmic microwave background (CMB) temperature and polarization in a characteristic way containing valuable information for cosmological parameter estimation and weak lensing reconstructions. So far, analytical expressions for the lensed CMB power spectra assume the probability density function (PDF) of the lensing excursion angle to be Gaussian. However, coherent light deflection by nonlinear structures at low redshifts causes deviations from a pure Gaussian PDF. Working in the flat-sky limit we develop a method for computing the lensed CMB power spectra which takes these non-Gaussian features into account. Our method does not assume any specific PDF but uses instead an expansion of the characteristic function of the lensing excursion angle into its moments. Measuring these in the CMB lensing deflection field obtained from the Millennium Simulation we show that the change in the lensed power spectra is only at the 0.1% - 0.4% level on very small scales (below 4 arcmin) and demonstrate that the assumption of a Gaussian lensing excursion angle PDF is well applicable.

description: Acoustic waves and pulses propagating from the solar photosphere upwards may quickly develop into shocks due to the rapid decrease of atmospheric density. However, if they propagate along a magnetic flux tube, then the nonlinear steepening may be balanced by tube dispersion effects. This may result in the formation of sausage soliton. The aim of this letter is to report an observational evidence of sausage soliton in the solar chromosphere. Time series of Ca II H line obtained at the solar limb with the Solar Optical Telescope (SOT) on the board of Hinode is analysed. Observations show an intensity blob, which propagates from 500 km to 1700 km above the solar surface with the mean apparent speed of 35 km s$^{-1}$. The speed is much higher than expected local sound speed, therefore the blob can not be a simple pressure pulse. The blob speed, length to width ratio and relative intensity correspond to slow sausage soliton propagating along a magnetic tube. The blob width is increased with height corresponding to the magnetic tube expansion in the stratified atmosphere. Propagation of the intensity blob can be the first observational evidence of slow sausage soliton in the solar atmosphere.

Rigorous coherent-structure theory for falling liquid films: Viscous dispersion effects on bound-state formation and self-organization

description: We examine the interaction of two-dimensional solitary pulses on falling liquid films. We make use of the second-order model derived by Ruyer-Quil and Manneville [Eur. Phys. J. B 6, 277 (1998); Eur. Phys. J. B 15, 357 (2000); Phys. Fluids 14, 170 (2002)] by combining the long-wave approximation with a weighted residuals technique. The model includes (second-order) viscous dispersion effects which originate from the streamwise momentum equation and tangential stress balance. These effects play a dispersive role that primarily influences the shape of the capillary ripples in front of the solitary pulses. We show that different physical parameters, such as surface tension and viscosity, play a crucial role in the interaction between solitary pulses giving rise eventually to the formation of bound states consisting of two or more pulses separated by well-defined distances and travelling at the same velocity. By developing a rigorous coherent-structure theory, we are able to theoretically predict the pulse-separation distances for which bound states are formed. Viscous dispersion affects the distances at which bound states are observed. We show that the theory is in very good agreement with computations of the second-order model. We also demonstrate that the presence of bound states allows the film free surface to reach a self-organized state that can be statistically described in terms of a gas of solitary waves separated by a typical mean distance and characterized by a typical density.

An analytical comparison of foxes within European and Japanese beast tales
Creators: name: Boss, Aaron
Publisher: name: University of British Columbia
Year: 2020

description: The use of foxes as a trickster figure is a common motif in cultures around the world, with two prominent manifestations being Reynard the Fox – the villainous protagonist of the Reynard Cycle from medieval and Early Modern Europe, and the kitsune – multiple-tailed supernatural foxes from Japanese folklore, literature, and mythology. 19th and early-to-mid 20th century scholarship utilized dated methodologies of formalism and structuralism, leading to comparisons of superficial similarities and speculations of a common origin. This thesis offers an analysis of both the Reynard Cycle and Japanese kitsune narratives utilizing methodologies drawn from both anthrozoology and cultural-historical analysis. I argue that the character of Reynard did not so much shape medieval European attitudes on foxes as he was shaped by pre-existing prejudices refracted through contemporary political concerns. In contrast, the kitsune of Japan encompass both secular and spiritual narratives, with their roles ranging from serving as moralistic – if sexist – warnings about women who did not conform to their social norms, to servants of Inari – the deity of commerce and agriculture, to the stars of tragic romances and vengeful plots to sow destruction and chaos. The thesis concludes by evaluating the two methodologies in relation to the two corpora.
Mixed motivic sheaves (and weights for them) exist if 'ordinary' mixed motives do

description: The goal of this paper is to prove: if certain 'standard' conjectures on motives over algebraically closed fields hold, then over any 'reasonable' $S$ there exists a motivic $t$-structure for the category of Voevodsky's $S$-motives (as constructed by Cisinski and Deglise). If $S$ is 'very reasonable' (for example, of finite type over a field) then the heart of this $t$-structure (the category of mixed motivic sheaves over $S$) is endowed with a weight filtration with semi-simple factors. We also prove a certain 'motivic decomposition theorem' (assuming the conjectures mentioned) and characterize semi-simple motivic sheaves over $S$ in terms of those over its residue fields. Our main tool is the theory of weight structures. We actually prove somewhat more than the existence of a weight filtration for mixed motivic sheaves: we prove that the motivic $t$-structure is transversal to the Chow weight structure for $S$-motives (that was introduced previously and independently by D. Hebert and the author; weight structures and their transversality with t-structures were also defined by the author in recent papers). We also deduce several properties of mixed motivic sheaves from this fact. Our reasoning relies on the degeneration of Chow-weight spectral sequences for 'perverse 'etale homology' (that we prove unconditionally); this statement also yields the existence of the Chow-weight filtration for such (co)homology that is strictly restricted by ('motivic') morphisms.

description: The measurement of the identified charged hadron p_t spectra using the ITS energy loss signal in the p-p data at sqrt{s}=900 GeV collected by the ALICE experiment at LHC will be discussed. It is performed using the Inner Tracking System (ITS) in stand-alone mode, both for track reconstruction and particle identification, allowing one to detect low momentum particles with p_t below 200 MeV/c. A second method using the tracks reconstructed by both the ITS and the Time Projection Chamber (TPC) has also been developed. The obtained results will be compared with the ones obtained from the TPC and from the Time Of Flight detector and used to extract the mean p_t value.

description: In this paper we argue that the set of wireless, mobile devices (e.g., portable telephones, tablet PCs, GPS navigators, media players) commonly used by human users enables the construction of what we term a digital ecosystem, i.e., an ecosystem constructed out of so-called digital organisms (see below), that can foster the development of novel distributed services. In this context, a human user equipped with his/her own mobile devices, can be though of as a digital organism (DO), a subsystem characterized by a set of peculiar features and resources it can offer to the rest of the ecosystem for use from its peer DOs. The internal organization of the DO must address issues of management of its own resources, including power consumption. Inside the DO and among DOs, peer-to-peer interaction mechanisms can be conveniently deployed to favor resource sharing and data dissemination. Throughout this paper, we show that most of the solutions and technologies needed to construct a digital ecosystem are already available. What is still missing is a framework (i.e., mechanisms, protocols, services) that can support effectively the integration and cooperation of these technologies. In addition, in the following we show that that framework can be implemented as a middleware subsystem that enables novel and ubiquitous forms of computation and communication. Finally, in order to illustrate the effectiveness of our approach, we introduce some experimental results we have obtained from preliminary implementations of (parts of) that subsystem.

description: Gli Archivi sono una parte fondamentale della cultura, hanno il compito di operare ai fini di una costruzione identitaria attraverso la testimonianza dei valori del passato i quali devono essere trasmessi correttamente alla società odierna. Il panorama archivistico è ricco di contenuti che meritano di essere valorizzati portandoli agli occhi del pubblico, in maniera tale che esso non ne percepisca solo l’aspetto visivo, ma anche il valore storico e importanza nella conservazione della memoria. Gli archivi non devono essere dunque considerati come luoghi statici e privi di identità nè tantomeno devono correre il rischio di essere dimenticati. La fotografia è uno strumento fondamentale per la conservazione della memoria. Le immagini possono essere la prova tangibile dell’evoluzione di una società e di un luogo, mostrano i cambiamenti storico-politici e le peculiarità del tempo in cui sono state scattate. Attraverso il confronto con l’attualità possono far scaturire ragionamenti e analisi di vario genere. Nel settore culturale innovazione e tecnologia sono sempre più necessarie ai fini di una mediazione al passo coi tempi. Le nuove tecnologie hanno rivoluzionato i sistemi tradizionali di gestione, valorizzazione, diffusione e fruizione dei beni culturali. Archivivi, come dice il nome, vuole rappresentare l’incontro tra il mondo degli archivi fotografici e l’innovazione. Poichè si propone una modalità di far ‘vivere’ gli archivi e il loro contenuto attraverso le potenzialità dello smartphone, sfruttando la fruizione dinamica e attiva che esso consente. Il progetto non punta unicamente alla creazione di un mezzo di mediazione, ma si pone l’obiettivo di trasporre l’ideale della valorizzazione e della tutela di questi luoghi e del loro contenuto. Il mondo degli archivi è dunque nelle mani di tutti, sia fisicamente (attraverso il proprio smartphone con l’app Archivivi) sia metaforicamente, perchè il futuro di queste istuzioni culturali di estrema importanza dipende dalla partecipazione del pubblico. Il nome del progetto quindi è l’unione delle parole ‘Archivi’ e ‘vivi’, l’utente vive l’esperienza partecipativa e attiva nei confronti degli archivi e anch’essi vivono e si innovano trasponendo il loro contenuto all’interno di uno strumento moderno e creato appositamente per la loro valorizzazione. Archivivi ha anche l’obiettivo di favorire gli l’archivi nel processo di divulgazione e mediazione, consentendo alle varie istituzioni, indipendentemente dalla loro dimensione o possibilità, di poter valorizzare il proprio contenuto e attività in modo personalizzato, attraverso un’apposito strumento che risponde alle loro esigenze. Non da ultimo il progetto ha anche lo scopo di incentivare il processo di digitalizzazione del patrimonio culturale visivo degli archivi. Il progetto è composto dal prototipo dell’applicazione Archivivi, e da vari supporti comunicativi sia cartacei che digitali, che hanno lo scopo di illustrare il funzionamento e le potenzialità dell’applicazione.

description: Aims: We present an automatised fitting procedure for the IR range of AGB star spectra. Furthermore we explore the possibilities and boundaries of this method. Methods: We combine the radiative transfer code DUSTY with the genetic algorithm PIKAIA in order to improve an existing spectral fit significantly. Results: In order to test the routine we carried out a performance test by feeding an artificially generated input spectrum into the program. Indeed the routine performed as expected, so, as a more realistic test set-up, we tried to create model fits for ISO spectra of selected AGB stars. Here we were not only able to improve existing fits, but also to show that a slightly altered dust composition may give a better fit for some objects. Conclusion: The use of a genetic algorithm in order to automatise the process of fitting stellar spectra seems to be very promising. We were able to improve existing fits and further offer a quantitative method to compare different models with each other. Nevertheless this method still needs to be studied and tested in more detail.

An efficient method for the incompressible Navier-Stokes equations on irregular domains with no-slip boundary conditions, high order up to the boundary

description: Common efficient schemes for the incompressible Navier-Stokes equations, such as projection or fractional step methods, have limited temporal accuracy as a result of matrix splitting errors, or introduce errors near the domain boundaries (which destroy uniform convergence to the solution). In this paper we recast the incompressible (constant density) Navier-Stokes equations (with the velocity prescribed at the boundary) as an equivalent system, for the primary variables velocity and pressure. We do this in the usual way away from the boundaries, by replacing the incompressibility condition on the velocity by a Poisson equation for the pressure. The key difference from the usual approaches occurs at the boundaries, where we use boundary conditions that unequivocally allow the pressure to be recovered from knowledge of the velocity at any fixed time. This avoids the common difficulty of an, apparently, over-determined Poisson problem. Since in this alternative formulation the pressure can be accurately and efficiently recovered from the velocity, the recast equations are ideal for numerical marching methods. The new system can be discretized using a variety of methods, in principle to any desired order of accuracy. In this work we illustrate the approach with a 2-D second order finite difference scheme on a Cartesian grid, and devise an algorithm to solve the equations on domains with curved (non-conforming) boundaries, including a case with a non-trivial topology (a circular obstruction inside the domain). This algorithm achieves second order accuracy (in L-infinity), for both the velocity and the pressure. The scheme has a natural extension to 3-D.

LUNES: Agent-based Simulation of P2P Systems (Extended Version)

description: We present LUNES, an agent-based Large Unstructured NEtwork Simulator, which allows to simulate complex networks composed of a high number of nodes. LUNES is modular, since it splits the three phases of network topology creation, protocol simulation and performance evaluation. This permits to easily integrate external software tools into the main software architecture. The simulation of the interaction protocols among network nodes is performed via a simulation middleware that supports both the sequential and the parallel/distributed simulation approaches. In the latter case, a specific mechanism for the communication overhead-reduction is used; this guarantees high levels of performance and scalability. To demonstrate the efficiency of LUNES, we test the simulator with gossip protocols executed on top of networks (representing peer-to-peer overlays), generated with different topologies. Results demonstrate the effectiveness of the proposed approach.

Low-Reynolds number swimming in gels

description: Many microorganisms swim through gels, materials with nonzero zero-frequency elastic shear modulus, such as mucus. Biological gels are typically heterogeneous, containing both a structural scaffold (network) and a fluid solvent. We analyze the swimming of an infinite sheet undergoing transverse traveling wave deformations in the "two-fluid" model of a gel, which treats the network and solvent as two coupled elastic and viscous continuum phases. We show that geometric nonlinearities must be incorporated to obtain physically meaningful results. We identify a transition between regimes where the network deforms to follow solvent flows and where the network is stationary. Swimming speeds can be enhanced relative to Newtonian fluids when the network is stationary. Compressibility effects can also enhance swimming velocities. Finally, microscopic details of sheet-network interactions influence the boundary conditions between the sheet and network. The nature of these boundary conditions significantly impacts swimming speeds.

Educazione musicale e lessico emotivo

description: In passato come oggi, la musica era concepita come un linguaggio al di là della parola, capace quindi di esprimere ciò che il verbale faticava a raccontare: i compositori mettevano emozioni, generate da situazioni immaginate o realmente vissute, nella loro musica, anche se attraverso modi e sensibilità differenti a seconda dell’estetica caratterizzante i diversi periodi storici, e coloro che ascoltavano ricercavano questo messaggio emotivo. Spesso le parole di cui disponiamo sono insufficienti a significare ogni sottile variazione emotiva (Goleman, 2018), in particolare i pre-adolescenti incontrano generalmente difficoltà nel nominare le loro emozioni poiché nuove e complesse. Questa ricerca ha lo scopo di osservare se attraverso un itinerario di Educazione musicale, incentrato sull’ascolto di musica strumentale, in cui gli allievi da fruitori diventano compositori, è possibile portare i ragazzi ad arricchire il loro lessico emotivo. I dati raccolti prima, durante e dopo l’intervento restituiscono una conferma delle ipotesi di partenza, anche se i risultati non sono generalizzabili poiché validi, secondo il principio della ricerca-azione, solo per la comunità educativa coinvolta. Un dato significativo concerne l’importanza della condivisione dopo un ascolto musicale: dopo esserci calati in un’altra esperienza, emotiva in questo caso, non torniamo infatti mai uguali a noi stessi; a volte ci sentiamo ispirati, altre volte rattristati, ma in ogni caso più ricchi (Wolf, 2012).

description: Quantum computers are susceptible to noises from the outside world. We investigate the effect of perturbation on the hitting time of a quantum walk and the stationary distribution prepared by a quantum walk based algorithm. The perturbation comes from quantizing a transition matrix Q with perturbation E (errors). We bound the perturbed quantum walk hitting time from above by applying Szegedy's work and the perturbation bounds with Weyl's perturbation theorem on classical matrix. Based on an efficient quantum sample preparation approach invented in {\em speed-up via quantum sampling} and the perturbation bounds for stationary distribution for classical matrix, we find an upper bound for the total variation distance between the prepared quantum sample and the true quantum sample.
