description: Monitoring the optical phase change in a fiber enables a wide range of applications where fast phase variations are induced by acoustic signals or vibrations in general. However, the quality of the estimated fiber response strongly depends on the method used to modulate the light sent to the fiber and capture the variations of the optical field. In this paper, we show that distributed optical fiber sensing systems can advantageously exploit techniques from the telecommunication domain, as those used in coherent optical transmission, to enhance their performance in detecting mechanical events, while jointly offering a simpler setup than widespread pulse-cloning or spectral-sweep based schemes with acousto-optic modulators. We periodically capture an overall fiber Jones matrix estimate thanks to a novel probing technique using two mutually orthogonal complementary (Golay) pairs of binary sequences applied simultaneously in phase and quadrature on two orthogonal polarization states. A perfect channel response estimation of the sensor array is achieved, subject to conditions detailed in the paper, thus enhancing the sensitivity and bandwidth of coherent phase-OTDR systems. High sensitivity, linear response, and bandwidth coverage up to 18 kHz are demonstrated with a sensor array composed of 10 fiber Bragg gratings (FBGs).

description: Topological wave structures -- phase vortices, skyrmions, merons, etc. -- are attracting enormous attention in a variety of quantum and classical wave fields. Surprisingly, these structures have never been properly explored in the most obvious example of classical waves: water-surface (gravity-capillary) waves. Here we fill this gap and describe: (i) water-wave vortices of different orders carrying quantized angular momentum with orbital and spin contributions, (ii) skyrmion lattices formed by the instantaneous displacements of the water-surface particles in wave interference, (iii) meron (half-skyrmion) lattices formed by the spin density vectors, as well as (iv) spatiotemporal water-wave vortices and skyrmions. We show that all these topological entities can be readily generated in linear water-wave interference experiments. Our findings can find applications in microfluidics and show that water waves can be employed as an attainable playground for emulating universal topological wave phenomena.

description: Multipartite entanglement enables secure and anonymous key exchange between multiple parties in a network. In particular Greenberger-Horne-Zeilinger (GHZ) states have been introduced as resource states for anonymous key exchange protocols, in which an anonymous subset of parties within a larger network establishes a secret key. However, the use of other types of multipartite entanglement for such protocols remains relatively unexplored. Here we demonstrate that linear cluster states can serve as a versatile and potentially scalable resource in such applications. We implemented an anonymous key exchange protocol with four photons in a linear cluster state and established a shared key between three parties in our network. We show how to optimize the protocol parameters to account for noise and to maximize the finite key rate under realistic conditions. As cluster states have been established as a flexible resource in quantum computation, we expect that our demonstration provides a first step towards their hybrid use for networked computing and communication.

description: The prevalence of online media has attracted researchers from various domains to explore human behavior and make interesting predictions. In this research, we leverage heterogeneous social media data collected from various online platforms to predict Taiwan's 2016 presidential election. In contrast to most existing research, we take a "signal" view of heterogeneous information and adopt the Kalman filter to fuse multiple signals into daily vote predictions for the candidates. We also consider events that influenced the election in a quantitative manner based on the so-called event study model that originated in the field of financial research. We obtained the following interesting findings. First, public opinions in online media dominate traditional polls in Taiwan election prediction in terms of both predictive power and timeliness. But offline polls can still function on alleviating the sample bias of online opinions. Second, although online signals converge as election day approaches, the simple Facebook "Like" is consistently the strongest indicator of the election result. Third, most influential events have a strong connection to cross-strait relations, and the Chou Tzu-yu flag incident followed by the apology video one day before the election increased the vote share of Tsai Ing-Wen by 3.66%. This research justifies the predictive power of online media in politics and the advantages of information fusion. The combined use of the Kalman filter and the event study method contributes to the data-driven political analytics paradigm for both prediction and attribution purposes.

description: Whereas the acuity of the position sense at the ankle can be disturbed by muscle fatigue, it recently also has been shown to be improved, under normal ankle neuromuscular state, through the use of an artificial tongue-placed tactile biofeedback. The underlying principle of this biofeedback consisted of supplying individuals with supplementary information about the position of their matching ankle position relative to their reference ankle position through electrotactile stimulation of the tongue. Within this context, the purpose of the present experiment was to investigate whether this biofeedback could mitigate the deleterious effect of muscle fatigue on joint position sense at the ankle. To address this objective, sixteen young healthy university students were asked to perform an active ankle-matching task in two conditions of No-fatigue and Fatigue of the ankle muscles and two conditions of No-biofeedback and Biofeedback. Measures of the overall accuracy and the variability of the positioning were determined using the absolute error and the variable error, respectively. Results showed that the availability of the biofeedback allowed the subjects to suppress the deleterious effects of muscle fatigue on joint position sense at the ankle. In the context of sensory re-weighting process, these findings suggested that the central nervous system was able to integrate and increase the relative contribution of the artificial tongue-placed tactile biofeedback to compensate for a proprioceptive degradation at the ankle.

description: In 1987, Liechtenstein et al. came up with the idea to formulate the problem of interatomic exchange interactions, which would describe the energy change caused by the infinitesimal rotations of spins, in terms of the magnetic susceptibility. The formulation appears to be very generic and, for isotropic systems, expresses the energy change in the form of the Heisenberg model, irrespectively on which microscopic mechanism stands behind the interaction parameters. Moreover, this approach establishes the relationship between the exchange interactions and the electronic structure obtained, for instance, in the first-principles calculations based on the density functional theory. The purpose of this review is to elaborate basic ideas of the linear response theories for the exchange interactions as well as more recent developments. The special attention is paid to the approximations underlying the original method of Liechtenstein et al. in comparison with its more recent and more rigorous extensions, the roles of the on-site Coulomb interactions and the ligand states, and calculations of antisymmetric Dzyaloshinskii-Moriya interactions, which can be performed alongside with the isotropic exchange, within one computational scheme. The abilities of the linear response theories as well as many theoretical nuances, which may arise in the analysis of interatomic exchange interactions, are illustrated on magnetic van der Walls materials Cr$X_3$ ($X$$=$ Cl, I), half-metallic ferromagnet CrO$_2$, ferromagnetic Weyl semimetal Co$_3$Sn$_2$S$_2$, and orthorhombic manganites $A$MnO$_3$ ($A$$=$ La, Ho), known for the peculiar interplay of the lattice distortion, spin, and orbital ordering.

description: Packing spheres efficiently in large dimension $d$ is a particularly difficult optimization problem. In this paper we add an isotropic interaction potential to the pure hard-core repulsion, and show that one can tune it in order to maximize a lower bound on packing density. Our results suggest that exponentially many (in the number of particles) distinct disordered sphere packings can be effectively constructed by this method, up to a packing fraction close to $7\, d\, 2^{-d}$. The latter is determined by solving the inverse problem of maximizing the dynamical glass transition over the space of the interaction potentials. Our method crucially exploits a recent exact formulation of the thermodynamics and the dynamics of simple liquids in infinite dimension.

description: In this work, we present a thermodynamical study of a Rindler modified Schwarzschild black hole under the consideration of small thermal fluctuations. In particular, we compute various stable macroscopic thermodynamic variables such as Hawking temperature, entropy, Helmholtz free energy, internal energy, enthalpy, and Gibbs free energy. To explore the effects of small statistical thermal fluctuations on stable thermodynamical parameters, we estimated the corrections to the various thermodynamical potentials of Rindler modified Schwarzschild black hole up to the first (leading) order and do a comparative study for the different values of correction parameter and Rindler acceleration parameter for fixed values of a cosmological constant. In this study, we examine the stability of black holes in the presence of thermal fluctuations. We find that when the correction parameter is positive, small-sized black holes remain stable, while large-sized ones become unstable. Conversely, when the correction parameter is negative, both small and large black holes exhibit instability. Additionally, we demonstrate that the first law of thermodynamics remains valid even in the presence of thermal fluctuations.

description: Tracking fish movements and sizes of fish is crucial to understanding their ecology and behaviour. Knowing where fish migrate, how they interact with their environment, and how their size affects their behaviour can help ecologists develop more effective conservation and management strategies to protect fish populations and their habitats. Deep learning is a promising tool to analyze fish ecology from underwater videos. However, training deep neural networks (DNNs) for fish tracking and segmentation requires high-quality labels, which are expensive to obtain. We propose an alternative unsupervised approach that relies on spatial and temporal variations in video data to generate noisy pseudo-ground-truth labels. We train a multitask DNN using these pseudo-labels. Our framework consists of three stages: (1) an optical flow model generates the pseudo labels using spatial and temporal consistency between frames, (2) a self-supervised model refines the pseudo-labels incrementally, and (3) a segmentation network uses the refined labels for training. Consequently, we perform extensive experiments to validate our method on three public underwater video datasets and demonstrate its effectiveness for video annotation and segmentation. We also evaluate its robustness to different imaging conditions and discuss its limitations.

description: Whether in the thermodynamic limit of lattice length infinite, hole concentration tending to zero, nonzero temperature, and U/t > 0 the charge stiffness of the 1D Hubbard model with first neighbor transfer integral t and on-site repulsion U is finite or vanishes and thus whether there is or there is no ballistic charge transport, respectively, remains an unsolved and controversial issue, as different approaches yield contradictory results. In this paper we provide an upper bound on the charge stiffness and show that (similarly as at zero temperature), for T >0 and U/t>0 it vanishes in the limit of zero hole concentration within the canonical ensemble in the thermodynamic limit. Moreover, we show that at high temperature the charge stiffness vanishes as well within the grand-canonical ensemble in the infinite lattice length limit and chemical potential approaching half the Mott-Hubbard gap. The lack of charge ballistic transport indicates that charge transport at finite temperatures is dominated by a diffusive contribution. Our scheme uses a suitable exact representation of the electrons in terms of rotated electrons for which the numbers of singly occupied and doubly occupied lattice sites are good quantum numbers for U/t>0. In contrast to often less controllable numerical studies, the use of such a representation reveals the carriers that couple to the charge probes and provides useful physical information on the microscopic processes behind the exotic charge transport properties of the 1D electronic correlated system under study.

description: A detailed study of the intermediate symmetry breaking scale, via the renormalization group equations, for a three generation heterotic string model arising from the N=2 superconformal construction is reported. The numerical study shows that the model admits a very large intermediate breaking scale $\op{>}{\sim}1.0\times10^{16}$ GeV. The role of the gauge singlets in this model is studied, and it is found that these fields play a crucial role in determining the directions and the scale of the intermediate symmetry breaking. The importance of the mixing in generation space is also studied. The generation mixing terms are found to have special effects in the intermediate symmetry breaking. Remarkably these terms can produce some {\it new} Yukawa couplings (not present at the Planck scale) through loops. These couplings are in general very small compared to the ones with non-vanishing tree level values and thus offer a {\it new} mechanism to solve the lepton/quark mass hierarchy problem.

Subjects: Glottodidattica; Corpus; Forestierismi; Corpus Linguistics

description: This paper aims at examining the principal benefits to Glottodidactics provided by the co-operation with Corpus Linguistics and by the analysis of loanwords. The first part of the present paper is a survey dealing with the involvement and cooperation between Glottodidactics and Corpus Linguistics, conveyed through the analysis of actual benefits and current developments: a rethinking in methods and characteristics of language acquisition process; the individualization of the role of the student as a researcher; the absence of anxiogenic factors; the presence of strong motivational elements. The second part is inspired by a shrewd guess that was made supposing that the use, or better, the recognition of particular lexical elements, such as loanwords, would be useful in a language acquisition process and, even more, in planning a language teaching “pathway”. A loanword, in its pure (or non-integrated) form, has a great potential in a glottodidactic perspective due to the stability of its aspect. On the other hand integrated loanwords have the special power to strengthen, to reinforce the mnemonic trace when added with a specific consideration about their aspect, their role, their meaning.

description: Employing a recently developed approach to dynamically emergent quantum thermodynamics, we revisit the thermodynamic behavior of the quantum Otto cycle with a focus on memory effects and strong system-bath couplings. Our investigation is based on an exact treatment of non-Markovianity by means of an exact quantum master equation, modelling the dynamics through the Fano-Anderson model featuring a peaked environmental spectral density. By comparing the results to the standard Markovian case, we find that non-Markovian baths can induce work transfer to the system, and identify specific parameter regions which lead to enhanced work output and efficiency of the cycle. In particular, we demonstrate that these improvements arise when the cycle operates in a frequency interval which contains the peak of the spectral density. This can be understood from an analysis of the renormalized frequencies emerging through the system-baths couplings.

description: We generalize the concept of Borel resummability and renormalons to a quantum field theory with an arbitrary number of fields and couplings, starting from the known notion based on the running coupling constants. An approach to identify the renormalons is provided by exploiting an analytic solution of the generic one-loop renormalization group equations in multi-field theories. Methods to evaluate the regions in coupling space where the theory is resummable are described. The generalization is then illustrated in a toy model with two coupled scalar fields, representing the simplest extension of the one-field analysis presented in the seminal works of the subject. Furthermore, possible links to realistic theories are briefly discussed.

description: Questo articolo si propone di mettere in luce alcune problematiche attuali che riguardano la lingua serbo-croata (o sarebbe più opportuno dire le lingue serba, croata, bosniaca e montenegrina). L’analisi parte dalla riforma di Vuk Stefanović Karadžić e dalla creazione delle basi della lingua serbo-croata, per arrivare ai giorni nostri. La lingua serbo-croata ufficialmente non esiste più nei paesi balcanici, sebbene sia stata in passato la lingua ufficiale di questa regione. Oggi ogni Stato ha una propria lingua, ciascuna con una propria denominazione, ovvero: croato, serbo, montenegrino e bosniaco. Sulla base dei lavori di Snježana Kordić, si cercherà da una parte di analizzare il concetto dell’unicità della lingua serbo-croata e la convinzione che tutte le altre rappresentino, in realtà, solo varianti policentriche di una lingua standard. Dall’altra, si prenderà in analisi la concezione opposta, secondo la quale le lingue bosniaca, croata, montenegrina e serba sono in realtà quattro lingue diverse fondate sul dialetto štokavo. La questione è complessa perché coinvolge ovviamente non solo problematiche linguistiche, ma anche questioni di natura ideologica e politica.

description: Effects on C$_{60}$ by thermal fluctuations of phonons, misalignment of C$_{60}$ molecules in a crystal, and other intercalated impurities (remaining C$_{70}$, oxygens, and so on) are simulated by disorder potentials. The Su-Schrieffer-Heeger--type electron-phonon model for doped C$_{60}$ is solved with gaussian bond disorders and also with site disorders. Sample average is performed over sufficient number of disorder configurations. The distributions of bond lengths and electron densities are shown as functions of the disorder strength and the additional electron number. Stability of polaron excitations as well as dimerization patterns is studied. Polarons and dimerizations in lightly doped cases (C$_{60}^{-1,-2}$) are relatively stable against disorders, indicated by peak structures in distribution functions. In more heavily doped cases, the several peaks merge into a single peak, showing the breakdown of polaron structures as well as the decrease of the dimerization strength. Possibility of the observation of polaronic lattice distortions and electron structures in doped C$_{60}$ is discussed.

description: Un segno non ha un significato, bensì è un significato. O meglio, un segno è molteplici, infiniti, indeterminati significati. Nella prassi linguistica quotidiana, dichiara radicalmente Wittgenstein, noi parliamo e ci comprendiamo, senza richiedere costantemente una spiegazione dei segni. Ricorriamo alla spiegazione del segno, ossia a una definizione di esso, quando vi è l’esigenza di un chiarimento circa la sua grammatica, vale a dire quando il segno è in qualche modo forestiero. Quando parliamo già sempre ci pre-comprendiamo per via dell’accordo nei segni, suoniamo infatti una tastiera comune. Solo quando non ci sentiamo a casa nostra nella lingua che parliamo, la comprensione si interrompe e ricorriamo perciò alla spiegazione. Solo in questi casi, solo nei casi in cui il non comprendere o il fraintendere interrompono il comprendere, allora siamo chiamati a interpretare la lingua, a tradurre cioè i segni momentaneamente fraintesi. Comprendere e interpretare, quindi, non coincidono. Per Wittgenstein, comprendere è parlare e interpretare è tradurre. Nella quotidianità comprendere è parlare nella misura in cui, sulla base di un sapere comune circa l’uso dei segni, parliamo e ci comprendiamo senza fermarci a interpretare i segni distinguendo da essi i significati. Noi interpretiamo i segni quando non li comprendiamo immediatamente e lo facciamo rinviando a segni altri. In tali casi quindi ricorriamo, per esempio, alle definizioni ostensive o verbali, le quali traducono i segni distinguendo da essi i significati.

description: We study traveling wave solutions for a nonlinear Schrödinger system with quadratic interaction. For the non mass resonance case, the system has no Galilean symmetry, which is of particular interest in this paper. We construct traveling wave solutions by variational methods and see that for the non mass resonance case there exist specific traveling wave solutions which correspond to the solutions for ``zero mass" case in nonlinear elliptic equations. We also establish the new global existence result for oscillating data as an application. Both of our results essentially come from the lack of Galilean invariance in the system.

Revelation and Equivalence: A Methodology for the Translation of Sacred-Texts; as applied to the Tiqqunim of the Zohar.
Creators: name: DAVID CHARLES SOLOMON

description: The thesis brings together two vibrant twenty-first-century academic disciplines, Translation Studies and the scholarship of Jewish mystical literature, towards a greater understanding of the inter-lingual translation of sacred texts. Proposing a methodology for an English translation of the medieval Aramaic writings known as the Tiqqunim of the Zohar, the thesis presents an original translation of three tiqqunic excerpts. The methodology utilises an approach to equivalent translation that recognises the unique revelatory and experiential nature of the Zohar, strives to reflect the ‘poetics of rupture’ of the source text, and seeks to satisfy the faithful expectations of communities of traditional readers.

description: Exotic compact objects refer to a wide class of black hole alternatives or effective models to describe phenomenologically quantum gravitational effects on the horizon scale. In this work we show how the knowledge of the quasi-normal mode spectrum of non-rotating wormhole models can be used to reconstruct the effective potential that appears in the perturbation equations. From this it is further possible to obtain the parameters that characterize the specific wormhole model, which in this paper was chosen to be the one by Damour and Solodukhin. We also address the question whether one can distinguish such type of wormholes from ultra compact stars, if only the quasi-normal mode spectrum is known. We have proven that this is not possible by using the trapped modes only, but requires additional information. The here presented inverse method is an extension of work that has previously been developed and applied to the oscillation spectra of ultra compact stars and gravastars. However, it is not limited to the study of exotic compact objects, but applicable to symmetric double barrier potentials that appear in one-dimensional wave equations. Therefore we think it can be of interest for other fields too.

Investigations on Improving Broadband Boundary Conditions in Gyrotron Interaction Modelling
Creators: name: Wu, Chuanren
Publisher: name: Karlsruhe
Year: 2014

description: Gyrotrons are microwave tubes capable of providing mega-watt power at millimetric wavelengths. The microwave power is produced by the conversion of the kinetic energy of an electron beam to electromagnetic wave energy. Simulations of the beam-wave interaction in the gyrotron cavity are essential for gyrotron design, as well as theoretical and experimental studies. In the usual gyrotron operation the spectrum of the generated radiation is concentrated around the nominal frequency. For this reason, the usual simulations consider only a narrow-band output spectrum (e.g. several GHz bandwidth comparing with the working frequency in the range of 100-200 GHz). As a result, the typical existing codes use a single-frequency radiation boundary condition for the generated electromagnetic field in the cavity. This condition is matched only at one frequency. However, there are two important aspects, which motivate an advanced formulation and implementation of the cavity boundary condition. Firstly, the occurrence of broadband effects (which may be several tens of GHz) in some cases, like dynamic after-cavity-interaction or modulation side-bands, requires a broadband boundary condition. Secondly, there are reflections from inside and outside of the gyrotron, which can only be considered in the simulation through a boundary condition with user-defined, frequency-dependent reflections. This master thesis proposes an improved formulation of the broadband boundary condition in the self-consistent, beam-wave interaction code Euridice. In this new formulation, two physical variables — the wave impedance and the axial wavenumber are expanded in polynomial series in the frequency domain. Because the beam-wave interaction process is simulated transiently in the time domain, the boundary condition should be also expressed in the time domain. This involves a non-trivial inverse Fourier transform, for which two solutions are proposed, tested and validated. It has been shown that, through the newly developed formulation, the existing matched boundary condition (that should yield zero-reflection in ideal case) can be improved by 15 dB even with a first-order polynomial series. Moreover, a user-defined, frequency-dependent complex reflection coefficient can be introduced. This was not possible with the previously existing boundary condition in Euridice.
IL LESSICO MENTALE BILINGUE E GLI SPAZI SEMANTICI DISTRIBUZIONALI: LE SIMILARITA’ TRA VERBI IN L1, IN L2 E NEI CORPORA
Creators: name: BOLOGNESI, MARIANNA

description: Gli spazi semantici distribuzionali sono modelli computazionali di lessico basati su corpora, in grado di reperire informazioni semantiche dai contesti di occorrenza delle parole e offrire mappe lessicali dove gli elementi sono tanto più vicini quanto più sono simili. L’analisi parte dall’osservazione delle occorrenze delle parole, contestualizzate nei testi che compongono i corpora, e genera similarità tra gli elementi sul piano paradigmatico. Pur senza inferire in maniera diretta e forzata un parallelo tra i meccanismi che soggiacciono a tali modelli e i meccanismi cognitivi che ci permettono di memorizzare le parole nel lessico mentale, questi strumenti offrono un potenziale applicativo molto alto, in quanto consentono di investigare in maniera estensiva le strutture e le dinamiche proprie della lingua viva. Nello studio proposto si confrontano le similarità semantiche tra verbi estratte attraverso l’implementazione di modelli dstribuzionali, con le similarità percepite da parlanti madrelingua e apprendenti stranieri.

Heavy Meson Masses in Chiral Perturbation Theory with Heavy Quark Symmetry

description: The $SU(3)$ and hyperfine mass splittings of mesons containing a single heavy quark are computed to one-loop order in chiral perturbation theory with heavy quark spin symmetry. Electromagnetic contributions of order $α_em$ are included. The observed values of the mass splittings are consistent with the one-loop chiral perturbation theory calculation. The $d-u$ hyperfine splitting $(D^{* +} - D^+) - (D^{*0} - D^0)$ is equal to $(m_d - m_u)/ m_s$ times the $s-d$ hyperfine splitting $(D_s^{* +} - D_s^+) - (D^{*+} - D^+)$ upto electromagnetic contributions. The small observed value of the $s-d$ hyperfine splitting implies that the $d-u$ hyperfine splitting is completely dominated by electromagnetic mass contributions.

description: Inspired by work of Szymik and Wahl on the homology of Higman-Thompson groups, we establish a general connection between ample groupoids, topological full groups, algebraic K-theory spectra and infinite loop spaces, based on the construction of small permutative categories of compact open bisections. This allows us to analyse homological invariants of topological full groups in terms of homology for ample groupoids.
 Applications include complete rational computations, general vanishing and acyclicity results for group homology of topological full groups as well as a proof of Matui's AH-conjecture for all minimal, ample groupoids with comparison.

description: Multi-storey Cross-Laminated Timber (CLT) buildings are gaining popularity throughout the world due to their many constructive and environmental advantages. Several researchers have proposed the use of post-tensioned rocking connections to improve the seismic performance of timber walled buildings. Although experimental results show that this system has a ductile behaviour and good energy dissipation characteristics, previous research also suggests that high inter-storey drifts and floor accelerations can develop in medium and high-rise timber buildings during earthquakes causing excessive non-structural and content damage. This paper studies the possibility of incorporating inerter-based dampers to reduce these demands and improve the overall seismic performance of Rocking CLT Walled buildings. Firstly, the seismic performance of a series of benchmark buildings designed using Direct Displacement Based Design (DDBD) procedures is assessed. Multiple Stripe Analyses (MSA) are performed to study the response of the buildings for a wide range of seismic intensity levels. The structural performance is examined in terms of peak inter-storey drifts and floor acceleration demands. Secondly, a Tuned InertoViscous Damper (TIVD) system is designed to obtain an effective mass ratio for the first mode of μr=0.1. A numerical model for the TIVD is defined and incorporated into the structural models previously analysed. Response history analyses are then performed on complete numerical models and the corresponding performance parameters compared in order to assess the effectiveness of the protective measure.
