description: The Cadmium Zinc Telluride (CZT) Imager on board AstroSat is a hard X-ray imaging spectrometer operating in the energy range of 20 $-$ 100 keV. It also acts as an open hard X-ray monitor above 100 keV capable of detecting transient events like the Gamma-ray Bursts (GRBs). Additionally, the instrument has the sensitivity to measure hard X-ray polarization in the energy range of 100 $-$ 400 keV for bright on-axis sources like Crab and Cygnus X-1 and bright GRBs. As hard X-ray instruments like CZTI are sensitive to cosmic rays in addition to X-rays, it is required to identify and remove particle induced or other noise events and select events for scientific analysis of the data. The present CZTI data analysis pipeline includes algorithms for such event selection, but they have certain limitations. They were primarily designed for the analysis of data from persistent X-ray sources where the source flux is much less than the background and thus are not best suited for sources like GRBs. Here, we re-examine the characteristics of noise events in CZTI and present a generalized event selection method that caters to the analysis of data for all types of sources. The efficacy of the new method is reviewed by examining the Poissonian behavior of the selected events and the signal to noise ratio for GRBs.

description: We have observed the quadruply lensed quasar 1RXS J1131-1231 with the integral field spectrograph mode of the Kyoto Tridimensional Spectrograph II mounted on the Subaru telescope. Its field of view has covered simultaneously the three brighter lensed images A, B, and C, which are known to exhibit anomalous flux ratios in their continuum emission. We have found that the [OIII] line flux ratios among these lensed images are consistent with those predicted by smooth-lens models. The absence of both microlensing and millilensing effects on this [OIII] narrow line region sets important limits on the mass of any substructures along the line of sight, which is expressed as M_E < 10^5 M_solar for the mass inside an Einstein radius. In contrast, the H_beta line emission, which originates from the broad line region, shows an anomaly in the flux ratio between images B and C, i.e., a factor two smaller C/B ratio than predicted by smooth-lens models. The ratio of A/B in the H_beta line is well reproduced. We show that the anomalous C/B ratio for the H_beta line is caused most likely by micro/milli-lensing of image C. This is because other effects, such as the differential dust extinction and/or arrival time difference between images B and C, or the simultaneous lensing of another pair of images A and B, are all unlikely. In addition, we have found that the broad H_beta line of image A shows a slight asymmetry in its profile compared with those in the other images, which suggests the presence of a small microlensing effect on this line emitting region of image A.

Τα αποτελέσματα της έρευνας έδειξαν ότι η συντριπτική πλειονότητα των εργαζομένων συμπεριφέρεται κατά τον πρώτο τύπο «μωρουδίστικο- γονεϊκό», ενώ ελάχιστα ήταν τα άτομα τα οποία αλληλεπιδρούν κατά τον δεύτερο «καθοδηγητικό» ή κατά τον τρίτο τύπο «συνεργατικό- παιδαγωγικό». Σημαντική διάσταση στον τρόπο με τον οποίο αλληλεπιδρούν οι εργαζόμενοι με τα άτομα με νοητική ανεπάρκεια αναδείχθηκε η κοινωνική κατασκευή της αναπηρίας καθώς και η έννοια του δρώντος υποκειμένου σύμφωνα με τη θεωρία της συμβολικής αλληλεπίδρασης.
description: This present study focuses on how special education staff interact with people with intellectual disability. The research intended to explore the ways of interaction through decoding the behavior of staff during the observation of their attitude towards people with intellectual disability. The attitude of special education staff can be classified in three interactional styles which have been described by Mark Rapley. The three interactional styles according to Mark Rapley (2004) are the following: “babying-parenting”, “instruction giving”, “collaboration-pedagogy”. The results of the survey showed that the overwhelming majority of staff acts according to the first interactional style, that is “babying- parenting”, while those who act according to the second “instruction giving” or to the third “collaboration- pedagogy” style are much fewer. Moreover, the social construction of disability as well as the concept of acting-subject according to the theory of symbolic interactionism have proven to be important parameters in the way staff interacts with people with intellectual disability.

description: Cadmium Zinc Telluride Imager (CZTI) onboard AstroSat has been a prolific Gamma-Ray Burst (GRB) monitor. While the 2-pixel Compton scattered events (100 - 300 keV) are used to extract sensitive spectroscopic information, the inclusion of the low-gain pixels (around 20% of the detector plane) after careful calibration extends the energy range of Compton energy spectra to 600 keV. The new feature also allows single-pixel spectroscopy of the GRBs to the sub-MeV range which is otherwise limited to 150 keV. We also introduced a new noise rejection algorithm in the analysis ('Compton noise'). These new additions not only enhances the spectroscopic sensitivity of CZTI, but the sub-MeV spectroscopy will also allow proper characterization of the GRBs not detected by Fermi. This article describes the methodology of single, Compton event and veto spectroscopy in 100 - 600 keV for the GRBs detected in the first year of operation. CZTI in last five years has detected around 20 bright GRBs. The new methodologies, when applied on the spectral analysis for this large sample of GRBs, has the potential to improve the results significantly and help in better understanding the prompt emission mechanism.

description: This paper derives the optimal Bayesian processing of an out-of-sequence (OOS) set of measurements in continuous-time for multiple target tracking. We consider a multi-target system modelled in continuous time that is discretised at the time steps when we receive the measurements, which are distributed according to the standard point target model. All information about this system at the sampled time steps is provided by the posterior density on the set of all trajectories. This density can be computed via the continuous-discrete trajectory Poisson multi-Bernoulli mixture (TPMBM) filter. When we receive an OOS measurement, the optimal Bayesian processing performs a retrodiction step that adds trajectory information at the OOS measurement time stamp followed by an update step. After the OOS measurement update, the posterior remains in TPMBM form. We also provide a computationally lighter alternative based on a trajectory Poisson multi-Bernoulli filter. The effectiveness of the two approaches to handle OOS measurements is evaluated via simulations.

Collaborative filtering
Stock price prediction
mean field variational inference

description: This thesis deals with dynamic statistical models applied to time-evolving dyadic processes, such as movie rating and stock price prediction. Specifically, a collaborative Kalman filter (CKF) is applied in order to model user-item interactions as latent locations that shift spatially with respect to a multidimensional Brownian motion. For this purpose, a time evolving drift parameter is learnt, which successfully captures stock price volatility over time. Variational approximation is applied to overcome intractability problems in posterior inference. For movie rating prediction, experiments have been conducted on data from Netflix prize competition. For stock price prediction AMEX, NYSE, and NASDAQ historical data from 1962 to 2017 have been used. Experimental results show that the resulting model outperforms several state-of-the-art methods in movie rating prediction. In this task, a root mean squared error of 0.7212 is achieved. In stock market, the learned Brownian motion drift parameter tracks closely stock price dynamic volatility. This fact leads to accurate stock price behavior estimation. The average root mean squared error in stock price range of 11.840-155.750, is 5.500.
description: Η παρούσα διπλωματική εργασία ασχολείται με δυναμικά στατιστικά μοντέλα που εφαρμόζονται σε χρονικά εξελισσόμενες διεργασίες, όπως η βαθμολογία ταινιών και η πρόβλεψη των τιμών των μετοχών. Συγκεκριμένα, ένα συνεργατικό φίλτρο Kalman (CKF) εφαρμόζεται για να μοντελοποιήσει τις αλληλεπιδράσεις χρηστών-αντικειμένων ως λανθάνουσες θέσεις που μετατοπίζονται χωρικά σε σχέση με μια πολυδιάστατη κίνηση Brown. Για το σκοπό αυτό, μαθαίνεται μια χρονοεξελισσόμενη παράμετρος ολίσθησης, η οποία συλλαμβάνει επιτυχώς την διακύμανση των τιμών των μετοχών στο χρόνο. Για την προσέγγιση των εκ των υστέρων κατανομών μέσω διαχειρίσιμων υπολογισμών , εφαρμόζεται μέθοδος μεταβολών μέσου πεδίου (mean-field variational method). Για την πρόβλεψη της βαθμολογίας των ταινιών, πραγματοποιήθηκαν πειράματα με δεδομένα από τον διαγωνισμό του Netflix. Για την πρόβλεψη των τιμών των μετοχών, χρησιμοποιήθηκαν τα ιστορικά δεδομένα που συμπεριλαμβάνονται στους χρηματιστηριακούς δείκτες AMEX, NYSE και NASDAQ από το 1962 έως το 2017. Τα πειραματικά αποτελέσματα δείχνουν ότι το προκύπτον μοντέλο υπερέχει των καθιερωμένων μεθόδων στην πρόβλεψη βαθμολόγησης ταινιών. Στην πρόβλεψη της βαθμολογίας ταινιών, η ρίζα μέσου τετραγωνικού σφάλματος (RMSE) είναι 0,7212. Στην πρόβλεψη τιμών μετοχών, η παράμετρος ολίσθησης Brown ακολουθεί στενά τη δυναμική μεταβλητότητα της τιμής των μετοχών. Το γεγονός αυτό οδηγεί σε ακριβή εκτίμηση της συμπεριφοράς των τιμών των μετοχών. Το μέσο ριζικό τετραγωνικό σφάλμα στην τιμή τιμών των μετοχών 11.840-155.750, είναι 5.500.

description: We aim at identifying very low-mass isolated planetary-mass member candidates in the nearest OB association to the Sun, Upper Scorpius (145 pc; 5-10 Myr), to constrain the form and shape of the luminosity function and mass spectrum in this regime. We conducted a deep multi-band ($Y$=21.2, $J$=20.5, $Z$=22.0 mag) photometric survey of six square degrees in the central region of Upper Scorpius. We extend the current sequence of astrometric and spectroscopic members by about two magnitudes in $Y$ and one magnitude in $J$, reaching potentially T-type free-floating members in the association with predicted masses below 5 Jupiter masses, well into the planetary-mass regime. We extracted a sample of 57 candidates in this area and present infrared spectroscopy confirming two of them as young L-type members with characteristic spectral features of 10 Myr-old brown dwarfs. Among the 57 candidates, we highlight 10 new candidates fainter than the coolest members previously confirmed spectroscopically. We do not see any obvious sign of decrease in the mass spectrum of the association, suggesting that star processes can form substellar objects with masses down to 4-5 Jupiter masses.

description: First, we construct the Taub-NUT/bolt solutions of $(2k+2)$-dimensinal Einstein-Maxwell gravity, when all the factor spaces of $2k$-dimensional base space $\mathcal{B}$ have positive curvature. These solutions depend on two extra parameters, other than the mass and the NUT charge. These are electric charge $q$ and electric potential at infinity $V$. We investigate the existence of Taub-NUT solutions and find that in addition to the two conditions of uncharged NUT solutions, there exist two extra conditions. These two extra conditions come from the regularity of vector potential at $r=N$ and the fact that the horizon at $r=N$ should be the outer horizon of the NUT charged black hole. We find that the NUT solutions in $2k+2$ dimensions have no curvature singularity at $r=N$, when the $2k$-dimensional base space is chosen to be $\mathbb{CP}^{2k}$. For bolt solutions, there exists an upper limit for the NUT parameter which decreases as the potential parameter increases. Second, we study the thermodynamics of these spacetimes. We compute temperature, entropy, charge, electric potential, action and mass of the black hole solutions, and find that these quantities satisfy the first law of thermodynamics. We perform a stability analysis by computing the heat capacity, and show that the NUT solutions are not thermally stable for even $k$'s, while there exists a stable phase for odd $k$'s, which becomes increasingly narrow with increasing dimensionality and wide with increasing $V$. We also study the phase behavior of the 4 and 6 dimensional bolt solutions in canonical ensemble and find that these solutions have a stable phase, which becomes smaller as $V$ increases.

description: Practical quantum networking architectures are crucial for scaling the connection of quantum resources. Yet quantum network testbeds have thus far underutilized the full capabilities of modern lightwave communications, such as flexible-grid bandwidth allocation. In this work, we implement flex-grid entanglement distribution in a deployed network for the first time, connecting nodes in three distinct campus buildings time-synchronized via the Global Positioning System (GPS). We quantify the quality of the distributed polarization entanglement via log-negativity, which offers a generic metric of link performance in entangled bits per second. After demonstrating successful entanglement distribution for two allocations of our eight dynamically reconfigurable channels, we demonstrate remote state preparation -- the first realization on deployed fiber -- showcasing one possible quantum protocol enabled by the distributed entanglement network. Our results realize an advanced paradigm for managing entanglement resources in quantum networks of ever-increasing complexity and service demands.

Gaussian effective potential for the standard model SU(2)xU(1) electroweak theory

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

description: The Gaussian Effective Potential (GEP) is derived for the non-Abelian SU(2)xU(1) gauge theory of electroweak interactions. First the problem of gauge invariance is addressed in the Abelian U(1) theory, where an optimized GEP is shown to be gauge invariant. The method is then extended to the full non-Abelian gauge theory where, at variance with naive derivations, the GEP is proven to be a genuine variational tool in any gauge. The role of ghosts is discussed and the unitarity gauge is shown to be the only choice which allows calculability without insertion of further approximations. The GEP for the standard model is derived and its predictions are compared to the known phenomenology, thus showing that the GEP provides an alternative non-perturbative description of the known experimental data. By a consistent renormalization of masses the full non-Abelian calculation confirms the existence of a light Higgs boson in the non-perturbative strong coupling regime of the Higgs sector.

description: Using Doppler velocity data from the SOI/MDI instrument onboard the SoHO spacecraft, we do time-distance helioseismic inversions for sound-speed perturbations beneath 16 sunspots observed in high-resolution mode. We clearly detect ring-like regions of enhanced sound speed beneath most sunspot penumbrae, extending from near the surface to depths of about 3.5 Mm. Due to their location and dependence on frequency bands of p-modes used, we believe these rings to be artifacts produced by a surface signal probably associated with the sunspot magnetic field.

Massive Scalar Perturbation of Extremal Rotating Braneworld Black hole: Superradiant Stability Analysis

Year: 2021
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We analyse the superradiant stability of braneworld extremal Kerr and Kerr-Newman black holes under massive scalar perturbation. These black hole solutions differ from their four dimensional counterpart by the presence of a tidal charge, which unlike electric charge, can take both positive and negative values and carries the signature of extra dimensions. We consider the perturbation of the brane geometry by a massive scalar field. From the radial equation of motion of the scalar field, we have found the effective potential felt by the field. For superradiant stability, there should not be any trapping well of the effective potential outside of the horizon. Using this condition we have specified the parameter space of superradiant stability which depends on parameters of both black hole and perturbation. In the case of Kerr-like extremal braneworld black holes, we have obtained a bound on tidal charge for superradiant stability under a massive scalar perturbation. Similarly, for slowly rotating Kerr-Newman like extremal braneworld black holes, we have obtained a lower bound of the product of mass to charge ratio of the black hole and scalar field, for which the system is superradiantly stable.

Analytic conformal bootstrap and Virasoro primary fields in the Ashkin-Teller model

description: We revisit the critical two-dimensional Ashkin-Teller model, i.e. the $\mathbb{Z}_2$ orbifold of the compactified free boson CFT at $c=1$. We solve the model on the plane by computing its three-point structure constants and proving crossing symmetry of four-point correlation functions. We do this not only for affine primary fields, but also for Virasoro primary fields, i.e. higher twist fields and degenerate fields. This leads us to clarify the analytic properties of Virasoro conformal blocks and fusion kernels at $c=1$. We show that blocks with a degenerate channel field should be computed by taking limits in the central charge, rather than in the conformal dimension. In particular, Al. Zamolodchikov's simple explicit expression for the blocks that appear in four-twist correlation functions is only valid in the non-degenerate case: degenerate blocks, starting with the identity block, are more complicated generalized theta functions.

description: The quantum phase transition between paramagnetic and antiferromagnetic phases of the Kondo lattice model with Ising anisotropy in the intersite exchange is studied within the framework of extended dynamical mean-field theory. Nonperturbative numerical solutions at zero temperature point to a continuous transition for both two- and three-dimensional magnetism. In the former case, the transition is associated with critical local physics, characterized by a vanishing Kondo scale and by an anomalous exponent in the dynamics close in value to that measured in heavy-fermion CeCu_{5.9}Au_{0.1}.

description: We study the effects of fluid-particle and particle-particle interactions in a three-dimensional monodispersed reactor with unstable fluidization. Simulations were conducted using the Immersed Boundary Method (IBM) for particle Reynolds numbers of 20-70 with an Archimedes number of 23600. Two different flow regimes were identified as a function of the particle Reynolds number. For low particle Reynolds numbers ($20 < Re_p < 40$), the porosity is relatively low and the particle dynamics are dominated by interparticle collisions that produce anisotropic particle velocity fluctuations. The relative importance of hydrodynamic effects increases with increasing particle Reynolds number, leading to a minimized anisotropy in the particle velocity fluctuations at an intermediate particle Reynolds number. For high particle Reynolds numbers ($Re_p > 40$), the particle dynamics are dominated by hydrodynamic effects, leading to decreasing and more anisotropic particle velocity fluctuations. A sharp increase in the anisotropy occurs when the particle Reynolds number increases from 40 to 50, corresponding to a transition from a regime in which collision and hydrodynamic effects are equally important (Regime 1) to a hydrodynamic-dominated regime (Regime 2). The results imply an optimum particle Reynolds number of roughly 40 for the investigated Archimedes number of 23600 at which mixing in the reactor is expected to peak, which is consistent with reactor studies showing peak performance at a similar particle Reynolds number and with a similar Archimedes number. Results also show that maximum effective collisions are attained at intermediate particle Reynolds number. Future work is required to relate optimum particle Reynolds number to Archimedes number.

description: Scalar-Tensor theories of gravity can be formulated in different frames, most notably, the Einstein and the Jordan one. While some debate still persists in the literature on the physical status of the different frames, a frame transformation in Scalar-Tensor theories amounts to a local redefinition of the metric, and then should not affect physical results. We analyze the issue in a cosmological context. In particular, we define all the relevant observables (redshift, distances, cross-sections, ...) in terms of frame-independent quantities. Then, we give a frame-independent formulation of the Boltzmann equation, and outline its use in relevant examples such as particle freeze-out and the evolution of the CMB photon distribution function. Finally, we derive the gravitational equations for the frame-independent quantities at first order in perturbation theory. From a practical point of view, the present approach allows the simultaneous implementation of the good aspects of the two frames in a clear and straightforward way.

When Outliers Are Different

description: When does the presence of an outlier in some measured property indicate that the outlying object differs qualitatively, rather than quantitatively, from other members of its apparent class? Historical examples include the many types of supernovæ and short {\it vs.\/} long Gamma Ray Bursts. There may be only one parameter and one outlier, so that principal component analyses are inapplicable. A qualitative difference implies that some parameter has a characteristic scale, and hence its distribution cannot be a power law (that can have no such scale). If the distribution is a power law the objects differ only quantitatively. The applicability of a power law to an empirical distribution may be tested by comparing the most extreme member to its next-most extreme. The probability distribution of their ratio is calculated, and compared to data for stars, radio and X-ray sources, and the fluxes, fluences and rotation measures of Fast Radio Bursts. It is found with high statistical significance that the giant outburst of soft gamma repeater SGR 1806-20 differed qualitatively from its lesser outbursts and FRB 200428 differed qualitatively from other FRB (by location in the Galaxy), but that in some supernova remnant models of rotation measure FRB 121102 is not, statistically significantly, an outlier.

description: This paper provides a county-level investigation of the root causes of gun violence in the U.S. To guide our empirical analysis, we develop a simple theoretical model which suggests that firearm-related offenses in a given county increase with the number of illegal guns and decrease with social capital and police intensity. Using detailed panel data from the Federal Bureau of Investigation for the period 1986-2014, we find empirical evidence for the causal effects of illegal guns, social capital, and police intensity consistent with our theoretical predictions. Based on our analysis, we derive a range of policy recommendations.
Policy Framing Report

description: The Policy Framing Report is the first public deliverable of the CASPER project (D3.1), which has the goal of studying the feasibility of a European certification system on gender equality targeting Universities and research organizations. The main objective of this report is to provide an overview of the current European policy frameworks regarding quality and excellence in Research and Higher Education and if/how they embed gender equality considerations. This overview is oriented towards the identification of the main windows of opportunities for the creation of a European level certification on gender equality in Higher Education and Research. The report mostly focuses on the main policy frameworks of the European Higher Education Area and the European Research Area; it also provides an overview of the role which gender equality has had in the Horizon 2020 programme, and of the role which it will probably take in the Horizon Europe programme. Some insights on the role of research and innovation in the new European gender equality strategy will also inform the overview.
 The second objective of this report is to provide a preliminary mapping of the most representative certification and award systems which relate to gender equality and diversity, which will also inform the identification of best practices for the potential European level certification.

Rational development of the solvent loaded, inductively coupled argon plasma
Creators: name: Weir, Douglas Glenn John
Publisher: name: University of British Columbia
Year: 2009

description: In routine trace metal analysis, the inductively coupled argon plasma (ICAP) converts analyte into atoms and atomic ions, then excites them to emit intense, characteristic line spectra. But none of the spectrochemical techniques based on the ICAP are free from interference effects. This dissertation focuses on only one source of interference effects: the solvent plasma load associated with injecting sample solution into the discharge as an aerosol mist. This dissertation reveals several physical phenomena that are responsible for both the spectral and nonspectral interference effects associated with solvent plasma loading, physical phenomena that are spatially, temporally and parametrically complex. In order to address that complexity, a strategy was proposed for characterizing and developing electrical gas discharges for spectrochemical analysis. The strategy consisted of three steps which are not strictly sequential. Step one: systematically survey the parametric, spatial and temporal complexity of analyte and background emission (Chapters 3-6); Step two: drawing guidelines from step one, characterize the physical properties of the discharge (Chapters 7-9); Step three: Improve the design and methodology of the spectrochemical method based on the insight gained in the first two steps. The first two steps proved to be very effective, but the third step remains untested.

description: Η παρούσα μελέτη στοχεύει στην παρουσίαση των αποτελεσμάτων μιας ανάλυσης λαθών παραγωγής γραπτού και προφορικού λόγου σε σχέση με τη χρήση της ρηματικής όψης στην ελληνική ως δεύτερη/ξένη γλώσσα. Τα δεδομένα της έρευνας προέρχονται από ιταλόφωνους μαθητές της ελληνικής ως δεύτερης/ξένης γλώσσας επιπέδου Α2 και Β2, ενώ η χρήση της ρηματικής όψης εξετάζεται σε περιβάλλοντα χρονικής αναφοράς στο παρελθόν και να- συμπληρωματικών προτάσεων. Όσον αφορά στην πειραματική διαδικασία, για την εκμαίευση προφορικού λόγου αξιοποιήθηκε η δοκιμασία της προφορικής ανάκλησης προτάσεων, ενώ η εκμαίευση γραπτού λόγου στηρίχθηκε στην τεχνική της γλωσσικής διδασκαλίας του δικτόγλωσσου. Τα αποτελέσματα της έρευνας μας δείχνουν πως το φαινόμενο της ρηματικής όψης δεν έχει κατακτηθεί, καθώς παρουσιάζονται δυσκολίες κατά τη χρήση του από τους μαθητές και των δύο επιπέδων. Και οι δυο ομάδες υπεργενικεύουν τη χρήση του συνοπτικού τύπου της ρηματικής όψης σε μη συνοπτικά περιβάλλοντα τόσο στην παραγωγή γραπτού όσο και στην παραγωγή προφορικού λόγου, ενώ οι επιδόσεις τους μοιάζουν καλύτερες στα περιβάλλοντα χρονικής αναφοράς στο παρελθόν παρά στα περιβάλλοντα να- συμπληρωματικών προτάσεων. Τα αποτελέσματα επιβεβαιώνουν πως η ρηματική όψη αποτελεί μια προβληματική κατηγορία για το σπουδαστή της ελληνικής ως δεύτερης/ξένης γλώσσας, ακόμη και σε σπουδαστές του Β2 επιπέδου, ενώ επισημαίνεται παράλληλα η εστίαση στη μελέτη της κωδικοποίησης της ρηματικής όψης στο σύστημα της μητρικής γλώσσας των μη φυσικών ομιλητών της ελληνικής.
description: This study explores the oral and written production of verbal aspect in L2 Greek. The survey data come from Italian-speaking students of Greek as a second/foreign language, who are at levels A2 and B2. The use of the verbal aspect consists of forms referring to the past and na-complement clauses. With regard to the experimental procedure, a sentence repetition task has been employed to elicit oral data, while the elicitation of written verb forms was based on the language teaching technique “dictogloss”. The results of the research show that the verbal aspect has not been fully mastered, as there are difficulties in written and oral production. Both L2 groups overgeneralized the perfective aspect in imperfective obligatory contexts, while the overgeneralization errors were more frequent in past verb forms, compared to na-complement clauses. The results confirm that the verbal aspect is a difficult phenomenon for the learners of Greek as a second/foreign language, even at B2 level. The data are discussed in the light of the way aspect is encoded in the learners’ L1, Italian.

description: The half quantum vortex(HQV) in condensate has been studied, since it was predicted by Salomaa and Volovik in superfluid $^3$He-A phase. However, an experimental evidence for its existence has not been reported so far. Motivated by a recent experimental report by Yamashita et al\cite{yamashita}, we study the HQVs in superfluid $^3$He confined between two parallel plates with a gap D $\sim$ 10 $μ$m in the presence of a magnetic field H $\sim$ 26 mT perpendicular to the parallel plates. We find that the bound HQVs are more stable than the singular vortices and free pairs of HQVs, when the rotation perpendicular to the parallel plates is below the critical speed, $Ω_c \sim$ 2 rad/s. The bound pair of HQVs accompanies the tilting of ${\hat d}$-vector out of the plane, which leads to an additional absorption in NMR spectra. Our study appears to describe the temperature and rotation dependence of the observed satellite NMR signal, which supports the existence of the HQVs in $^3$He.

description: We present an energy scaling function to predict, in a specific range, the energy of bosonic trimers with large scattering lengths and finite range interactions, which is validated by quantum Monte Carlo calculations using microscopic Hamiltonians with two- and three-body potentials. The proposed scaling function depends on the scattering length, effective range, and a reference energy, which we chose as the trimer energy at unitarity. We obtained the scaling function as a limit cycle from the solution of the renormalized zero-range model with effective range corrections. We proposed a simple parametrization of the energy scaling function. Besides the intrinsic interest in theoretical and experimental investigations, this scaling function allows one to probe Efimov physics with only the trimer ground states, which may open opportunities to identify Efimov trimers whenever access to excited states is limited.
