description: We investigate the relationship between 8.44\,GHz brightness temperatures and 1.4 to 8.44\,GHz radio spectral indices with 6.2\,$μ$m polycyclic aromatic hydrocarbon (PAH) emission and 9.7\,$μ$m silicate absorption features for a sample of 36 local luminous and ultra-luminous infrared galaxies. We find that galaxies having small 6.2\,$μ$m PAH equivalent widths (EQWs), which signal the presence of weak PAH emission and/or an excess of very hot dust, also have flat spectral indices. The three active galactic nuclei (AGN) identified through their excessively large 8.44\,GHz brightness temperatures are also identified as AGN via their small 6.2\,$μ$m PAH EQWs. We also find that the flattening of the radio spectrum increases with increasing silicate optical depth, 8.44\,GHz brightness temperature, and decreasing size of the radio source even after removing potential AGN, supporting the idea that compact starbursts show spectral flattening as the result of increased free-free absorption. These correlations additionally suggest that the dust obscuration in these galaxies must largely be coming from the vicinity of the compact starburst itself, and is not distributed throughout the (foreground) disk of the galaxy. Finally, we investigate the location of these infrared-bright systems relative to the main sequence (star formation rate vs. stellar mass) of star-forming galaxies in the local universe. We find that the radio spectral indices of galaxies flattens with increasing distance above the main sequence, or in other words, with increasing specific star formation rate. This indicates that galaxies located above the main sequence, having high specific star formation rates, are typically compact starbursts hosting deeply embedded star formation that becomes more optically thick in the radio and infrared with increased distance above the main sequence.

description: One-time readout temporal ghost imaging is attempted by utilizing optoelectronic devices that are not originally intended for signal photon detection purposes and as such slow by design. A visible light-emitting diode having a response time $τ$=0.036 ms and a solar cell with $τ$=3.1ms are used to retrieve a rectangular pulse train, which is otherwise rounded with significant overlapping, in the image of a temporal mask simply by capturing data once at a selected single time effective operation duration are discussed.

description: A localized qubit entangled with a propagating quantum field is well suited to study non-local aspects of quantum mechanics and may also provide a channel to communicate between spatially separated nodes in a quantum network. Here, we report the on demand generation and characterization of Bell-type entangled states between a superconducting qubit and propagating microwave fields composed of zero, one and two-photon Fock states. Using low noise linear amplification and efficient data acquisition we extract all relevant correlations between the qubit and the photon states and demonstrate entanglement with high fidelity.

description: The effects of the anisotropy on the fluid pulsation modes adopting the so-called Cowling approximation and tidal deformability of strange quark stars are investigated by using the numerical integration of the hydrostatic equilibrium, nonradial oscillations, and tidal deformability equations, being these equations modified from their standard form to include the anisotropic effects. The fluid matter inside the compact stars is described by the MIT bag model equation of state. For the anisotropy profile, we consider a local anisotropy that is both regular at the center and null at the star's surface. We find that the effect of the anisotropy is reflected in the fluid pulsation modes and tidal deformability. Finally, we analyze the correlation between the tidal deformability of the GW$170817$ event with the anisotropy.

description: Nonlocal nucleon-nucleus optical potential with rotational quadrupole deformation enabling the excitation of the ${}^{24}\mathrm{Mg}(2^+)$ state is developed; it fits well the proton-${}^{24}\mathrm{Mg}$ elastic and inelastic differential cross section in the beam energy range from 30 to 45 MeV per nucleon. The inelastic deuteron-${}^{24}\mathrm{Mg}$ scattering leading to the excited ${}^{24}\mathrm{Mg}(2^+)$ state is studied in the same energy regime by solving the three-body Faddeev-type equations for transition operators. Effects of the optical potential nonlocality are evaluated by comparison with local models. Significant effects on the inelastic differential cross section are found at forward angles up to the first peak and at larger angles beyond the second peak. Nonlocal optical potential provides a simultaneous reasonable reproduction of the experimental data for the elastic and inelastic proton-${}^{24}\mathrm{Mg}$ and deuteron-${}^{24}\mathrm{Mg}$ scattering, not achieved using local potentials.

description: The harmonically confined Vicsek model displays qualitative and quantitative features observed in natural insect swarms. It exhibits a scale free transition between single and multicluster chaotic phases. Finite size scaling indicates that this unusual phase transition occurs at zero confinement [Physical Review E 107, 014209 (2023)]. While the evidence of the scale-free-chaos phase transition comes from numerical simulations, here we present its mean field theory. Analytically determined critical exponents are those of the Landau theory of equilibrium phase transitions plus dynamical critical exponent $z=1$ and a new critical exponent $φ=0.5$ for the largest Lyapunov exponent. The phase transition occurs at zero confinement and noise in the mean field theory. The noise line of zero largest Lyapunov exponents informs observed behavior: (i) the qualitative shape of the swarm (on average, the center of mass rotates slowly at the rate marked by the winding number and its trajectory fills compactly the space, similarly to the observed condensed nucleus surrounded by vapor), and (ii) the critical exponents resemble those observed in natural swarms. Our predictions include power laws for the frequency of the maximal spectral amplitude and the winding number.

description: Consider an SDE on a foliated manifold whose trajectories lay on compact leaves. We investigate the effective behavior of a small transversal perturbation of order $\varepsilon$. An average principle is shown to hold such that the component transversal to the leaves converges to the solution of a deterministic ODE, according to the average of the perturbing vector field with respect to invariant measures on the leaves, as $\varepsilon$ goes to zero. An estimate of the rate of convergence is given. These results generalize the geometrical scope of previous approaches, including completely integrable stochastic Hamiltonian system.

description: We present a semiclassical analysis of the quantum propagator of a particle confined on one side by a steeply, monotonically rising potential. The models studied in detail have potentials proportional to $x^α$ for $x>0$; the limit $α\to\infty$ would reproduce a perfectly reflecting boundary, but at present we concentrate on the cases $α=1$ and 2, for which exact solutions in terms of well known functions are available for comparison. We classify the classical paths in this system by their qualitative nature and calculate the contributions of the various classes to the leading-order semiclassical approximation: For each classical path we find the action $S$, the amplitude function $A$ and the Laplacian of $A$. (The Laplacian is of interest because it gives an estimate of the error in the approximation and is needed for computing higher-order approximations.) The resulting semiclassical propagator can be used to rewrite the exact problem as a Volterra integral equation, whose formal solution by iteration (Neumann series) is a semiclassical, not perturbative, expansion. We thereby test, in the context of a concrete problem, the validity of the two technical hypotheses in a previous proof of the convergence of such a Neumann series in the more abstract setting of an arbitrary smooth potential. Not surprisingly, we find that the hypotheses are violated when caustics develop in the classical dynamics; this opens up the interesting future project of extending the methods to momentum space.

description: Standard binary evolutionary models predict a significant population of core helium-burning stars that lost their hydrogen-rich envelope after mass transfer via Roche-lobe overflow. However, there is a scarcity of observations of such stripped stars in the intermediate mass regime (~1.5 - 8$ M_{\odot}$), which are thought to be prominent progenitors of SN Ib/c. Especially at low metallicity, a significant fraction of these stars is expected to be only partially stripped, retaining a significant amount of hydrogen on their surfaces. For the first time, we discovered a partially stripped massive star in a binary with a Be-type companion located in the Small Magellanic Cloud (SMC) using a detailed spectroscopic analysis. The stripped-star nature of the primary is revealed by the extreme CNO abundance pattern and very high luminosity-to-mass ratio, which suggest that the primary is likely shell-hydrogen burning. Our target SMCSGS-FS 69 is the most luminous and most massive system among the known stripped star + Be binaries, with Mstripped ~3$ M_{\odot}$ and MBe ~17$ M_{\odot}$. Binary evolutionary tracks suggest an initial mass of Mini $\gtrsim 12 M_{\odot}$ for the stripped star and predict it to be in a transition phase towards a hot compact He star, which will eventually produce a stripped-envelope supernova. Our target marks the first representative of a so-far missing evolutionary stage in the formation pathway of Be X-ray binaries and double neutron star mergers.

description: We show that when spatially localized gain landscape performs accelerated motion in the transverse plane, i.e., when it rotates or oscillates around the light propagation axis, the effective gain experienced by the light beam considerably reduces with increase of the amplitude of oscillations or frequency of rotation of the localized gain. In the presence of uniform background losses and defocusing nonlinearity, such gain landscapes may support dynamically oscillating gain-managed solitons, but if the amplitude of oscillations or the frequency of rotation of the localized gain exceeds a threshold, stable attractors disappear and any input beam decays.

description: Στην παρούσα διπλωματική εργασία γίνεται εφαρμογή της μεθόδου της Ισορροπημένης Κάρτας Επιδόσεων (Ι.Κ.Ε) -Βalanced Scorecard (B.Sc.) σε μεγάλη βιομηχανική μονάδα της Κρήτης. Η μέθοδος αυτή αποτελεί ένα αποτελεσματικό εργαλείο υποστήριξης και αξιολόγησης των στρατηγικών αποφάσεων μέσα σε μια επιχείρηση, βιομηχανία ή δημόσιο οργανισμό μέσω της αποτελεσματικής μέτρησης των επιχειρησιακών επιδόσεων. Αποτελεί επίσης κρίσιμο εργαλείο για την ευθυγράμμιση των βραχυπρόθεσμων ενεργειών με την στρατηγική της εταιρείας αλλά και μέσο επικοινωνίας καθώς δίνει τη δυνατότητα μετάφρασης της στρατηγικής της εταιρείας και μετάδοσής της στους εργαζομένους. Βασίζεται στην ανάπτυξη ενός συνόλου δεικτών μέτρησης της επιχειρηματικής αποδοτικότητας, χρησιμοποιώντας οικονομικές και μη επιδόσεις. Η υιοθέτηση μιας φιλοσοφίας συνεχούς βελτίωσης, η εστίαση στον πελάτη και ο αναλυτικός καθορισμός επιχειρησιακών διαδικασιών αποτελούν τα βασικά στοιχεία εφαρμογής της μεθόδου στα πλαίσια της Διοίκησης Ολικής Ποιότητας. Οι σημαντικότερες διαστάσεις του μοντέλου αφορούν την οικονομική διάσταση, τη διάσταση των πελατών, τη διάσταση των εσωτερικών διαδικασιών (διαδικασίες, διαχείριση ανθρωπίνων πόρων, κ.λπ.) και τέλος τη διάσταση της εκπαίδευσης και ανάπτυξης (καινοτομία, συνεχής βελτίωση, κ.λπ.). Ξεκινώντας τη μεθοδολογία θα πρέπει να αποσαφηνιστεί το όραμα και η αποστολή της εταιρείας.

description: In this work, we address the challenging task of few-shot and zero-shot 3D point cloud semantic segmentation. The success of few-shot semantic segmentation in 2D computer vision is mainly driven by the pre-training on large-scale datasets like imagenet. The feature extractor pre-trained on large-scale 2D datasets greatly helps the 2D few-shot learning. However, the development of 3D deep learning is hindered by the limited volume and instance modality of datasets due to the significant cost of 3D data collection and annotation. This results in less representative features and large intra-class feature variation for few-shot 3D point cloud segmentation. As a consequence, directly extending existing popular prototypical methods of 2D few-shot classification/segmentation into 3D point cloud segmentation won't work as well as in 2D domain. To address this issue, we propose a Query-Guided Prototype Adaption (QGPA) module to adapt the prototype from support point clouds feature space to query point clouds feature space. With such prototype adaption, we greatly alleviate the issue of large feature intra-class variation in point cloud and significantly improve the performance of few-shot 3D segmentation. Besides, to enhance the representation of prototypes, we introduce a Self-Reconstruction (SR) module that enables prototype to reconstruct the support mask as well as possible. Moreover, we further consider zero-shot 3D point cloud semantic segmentation where there is no support sample. To this end, we introduce category words as semantic information and propose a semantic-visual projection model to bridge the semantic and visual spaces. Our proposed method surpasses state-of-the-art algorithms by a considerable 7.90% and 14.82% under the 2-way 1-shot setting on S3DIS and ScanNet benchmarks, respectively.

description: This paper extends the dual calculus with inductive types and coinductive types. The paper first introduces a non-deterministic dual calculus with inductive and coinductive types. Besides the same duality of the original dual calculus, it has the duality of inductive and coinductive types, that is, the duality of terms and coterms for inductive and coinductive types, and the duality of their reduction rules. Its strong normalization is also proved, which is shown by translating it into a second-order dual calculus. The strong normalization of the second-order dual calculus is proved by translating it into the second-order symmetric lambda calculus. This paper then introduces a call-by-value system and a call-by-name system of the dual calculus with inductive and coinductive types, and shows the duality of call-by-value and call-by-name, their Church-Rosser properties, and their strong normalization. Their strong normalization is proved by translating them into the non-deterministic dual calculus with inductive and coinductive types.

description: Στις μέρες μας, στις σύγχρονες αγορές οι συγχωνεύσεις και οι εξαγορές αποτελούν ένα φαινόμενο το οποίο βρίσκεται σε έξαρση, εξαιτίας της ανάγκης που έχει δημιουργηθεί για τη συγκέντρωση κεφαλαίων. Αυτό συμβαίνει, διότι οι εταιρείες που πραγματοποιούν Σ&Ε λαμβάνουν μεγάλη οφέλη από τέτοιου είδους συμφωνίες. Με αυτό τον τρόπο μπορούν να δραστηριοποιηθούν σε διαφορετικούς κλάδους, να γίνουν περισσότερο ανταγωνιστικές και να εδραιώσουν τη θέση τους σε ένα συνεχώς μεταβαλλόμενο περιβάλλον.
Στην παρούσα εργασία πραγματοποιείται μια ανάλυση των χρηματοοικονομικών δεικτών κάποιων εταιρειών που πραγματοποίησαν Σ&Ε από το 1997 έως και το 2015 και πως μια τέτοιου είδους συμφωνία επηρέασε τα οικονομικά στοιχεία των επιχειρήσεων ένα χρόνο μετά τη συμφωνία σε σχέση με ένα χρόνο πριν.
Στην επεξεργασία που πραγματοποιήθηκε χρησιμοποιήθηκαν 1691 εταιρείες – εξαγοραστές και  1953 εταιρείες – στόχοι, οι οποίοι δραστηριοποιούνται στην Ευρώπη. Η σύγκριση των χρηματοοικονομικών δεικτών έγινε με το πρόγραμμα SPSS χρησιμοποιώντας την μέθοδο πολυμεταβλητής ανάλυσης διασποράς (MANOVA) και τον έλεγχο υποθέσεων t για ζευγαρωτά δείγματα (Paired Sample T-test).
Στο πρώτο μέρος της εργασίας γίνεται λόγος για τις έννοιες των Σ&Ε, καθώς και μια ιστορική αναδρομή από τη δεκαετία που πρωτοεμφανίστηκαν έως και σήμερα. Έπειτα, στο δεύτερο μέρος παρουσιάζονται αναλυτικά τα κίνητρα τα οποία οδηγούν σε συμφωνίες Σ&Ε, οι παράγοντες επιτυχίες και αποτυχίας μιας συμφωνίας, ενώ καταγράφηκαν  και τα πλεονεκτήματα και τα μειονεκτήματα. Στο τρίτο μέρος, γίνεται αναλυτική παρουσίαση των χρηματοοικονομικών δεικτών που χρησιμοποιήθηκαν και των αποτελεσμάτων που εξήχθησαν. Τέλος, στο τέταρτο μέρος της εργασίας καταγράφονται τα συμπεράσματα που προέκυψαν.

description: Ein Konvolut einzelner Schmuckstücke und die Goldbeigaben eines angeblichen Grabfundes wurden technologisch und analytisch untersucht. Die meisten Objekte sind Blecharbeiten, die aus einer Vielzahl von Einzelteilen mit metallischem Goldlot zusammengefügt und mit Granulation oder granulations-imitierendem Perl- oder Kerbdraht verziert wurden. Nur vier kleine Ohrringe sind massiv gegossen. Zwei Zierbleche dürften über Patrizen (Positivmodeln), die Deckel der Astragale in Matrizen (Negativmodeln) geformt worden sein. Alle Objekte wurden mit Synchrotron- und atmosphärischer Röntgenfluoreszenz analysiert. Die Daten zeigen das breite Spektrum an Goldlegierungen, die im 7./6. Jahrhundert v. Chr. in Kleinasien verarbeitet wurden: vom natürlichen Seifengold (Elektrum) bis zu geläutertem, fast reinem Gold. Eine Korrelation zwischen Goldqualität und Verarbeitungsmethode konnte nicht festgestellt werden. Sowohl hochreines als auch mit viel Silber und Kupfer legiertes Gold wurde zum Schmieden von Blecharbeiten, aber auch zum Massivguss verwendet. Aus der Goldfarbe kann wegen des Phänomens der oberflächlichen Goldanreicherung nicht auf eine Legierungszusammensetzung geschlossen werden. Der 1963 angekaufte Fundkomplex aus lydischen Metallarbeiten und ostionischen Salbgefäßen aus Ton dürfte einen Grabfund des frühen 6. Jahrhunderts v. Chr. darstellen, dessen Herkunft aus Ephesos jedoch nicht zu sichern ist.

description: We consider a generalization of the quintessence type scalar field cosmological models, by adding a multiplicative dissipative term in the scalar field Lagrangian, which is represented in an exponential form. The generalized dissipative Klein-Gordon equation is obtained from the variational principle in a covariant form. The energy-momentum tensor of the dissipative scalar field is also obtained from the dissipative Lagrangian. The generalized Friedmann equations in the presence of the dissipative scalar field are obtained for a specific form of dissipation, with the dissipation exponent represented as the time integral of the product of the Hubble function, and of a function describing the dissipative properties of the scalar field. Several cosmological models, corresponding to different choices of the dissipation function, and of the scalar field potential, are considered in detail. The evolutions of the basic cosmological parameters (Hubble function, deceleration parameter etc.) are investigated by using both analytical and numerical techniques. A comparison with the observational data for the Hubble function, and with the predictions of the standard $Λ$CDM paradigm is also presented for each dissipative scalar field model. In the large time limit the model describes an accelerating Universe, with the effective negative pressure induced by the dissipative effects associated to the scalar field. Accelerated expansion in the absence of the scalar field potential is also possible, with the kinetic term dominating the expansionary evolution. The dissipative scalar field models describe well the observational data, with the free parameters of the model obtained by a trial and error method. The obtained results show that the dissipative scalar field model offers an effective dynamical possibility for explaining the recent cosmological observational data.

description: This paper presents an analytical investigation on the outage performance of dual-hop multiple antenna amplify-and-forward relaying systems in the presence of interference. For both the fixed-gain and variable-gain relaying schemes, exact analytical expressions for the outage probability of the systems are derived. Moreover, simple outage probability approximations at the high signal to noise ratio regime are provided, and the diversity order achieved by the systems are characterized. Our results suggest that variable-gain relaying systems always outperform the corresponding fixed-gain relaying systems. In addition, the fixed-gain relaying schemes only achieve diversity order of one, while the achievable diversity order of the variable-gain relaying scheme depends on the location of the multiple antennas.

Phonon-mediated superconductivity in the Sb-square-net compound LaCuSb$_2$

description: We investigated the electronic structure and superconducting properties of single-crystalline LaCuSb$_2$. The resistivity, magnetization, and specific heat measurements showed that LaCuSb$_2$ is a bulk superconductor. The observed Shubnikov-de Haas oscillation and magnetic field dependence of the Hall resistivity can be reasonably understood assuming a slightly hole-doped Fermi surface. Electron-phonon coupling calculation clarified the difference from the isostructural compound LaAgSb$_2$ indicating that (i) low-frequency vibration modes related to the interstitial layer sandwiched between the Sb-square nets significantly contribute to the superconductivity and (ii) carriers with sizable electron--phonon coupling distribute isotropically on the Fermi surface. These are assumed to be the origin of higher superconducting transition temperature compared with LaAgSb$_2$. We conclude that the superconducting properties of LaCuSb$_2$ can be understood within the framework of conventional phonon-mediated mechanism.

description: The use of machine learning (ML) in chemical physics has enabled the construction of interatomic potentials having the accuracy of ab initio methods and a computational cost comparable to that of classical force fields. Training an ML model requires an efficient method for the generation of training data. Here we apply an accurate and efficient protocol to collect training data for constructing a neural network based ML interatomic potential for nanosilicate clusters. Initial training data are taken from normal modes and farthest point sampling. Later on, the set of training data is extended via an active learning strategy in which new data are identified by the disagreement between an ensemble of ML models. The whole process is further accelerated by parallel sampling over structures. We use the ML model to run molecular dynamics (MD) simulations of nanosilicate clusters with various sizes, from which infrared spectra with anharmonicity included can be extracted. Such spectroscopic data are needed for understanding the properties of silicate dust grains in the interstellar medium (ISM) and in circumstellar environments.
