description: We address a number of puzzles relating to the proposed formulae for the degeneracies of dyons in orbifold compactifications of the heterotic string to four dimensions with $N =4$ supersymmetry. The partition function for these dyons is given in terms of Siegel modular forms associated with genus-two Riemann surfaces. We point out a subtlety in demonstrating S-duality invariance of the resulting degeneracies and give a prescription that makes the invariance manifest. We show, using M-theory lift of string webs, that the genus-two contribution captures the degeneracy only if a specific irreducibility criterion is satisfied by the charges. Otherwise, in general there can be additional contributions from higher genus Riemann surfaces. We analyze the negative discriminant states predicted by the formula. We show that even though there are no big black holes in supergravity corresponding to these states, there are multi-centered particle-like configurations with subleading entropy in agreement with the microscopic prediction and our prescription for S-duality invariance. The existence of the states is moduli dependent and we exhibit the curves of marginal stability and comment on its relation to S-duality invariance.

Towards Large Scale Automated Algorithm Design by Integrating Modular Benchmarking Frameworks

Subjects: subject: Neural and Evolutionary Computing (cs.NE)

description: We present a first proof-of-concept use-case that demonstrates the efficiency of interfacing the algorithm framework ParadisEO with the automated algorithm configuration tool irace and the experimental platform IOHprofiler. By combing these three tools, we obtain a powerful benchmarking environment that allows us to systematically analyze large classes of algorithms on complex benchmark problems. Key advantages of our pipeline are fast evaluation times, the possibility to generate rich data sets to support the analysis of the algorithms, and a standardized interface that can be used to benchmark very broad classes of sampling-based optimization heuristics. In addition to enabling systematic algorithm configuration studies, our approach paves a way for assessing the contribution of new ideas in interplay with already existing operators -- a promising avenue for our research domain, which at present may have a too strong focus on comparing entire algorithm instances.

Scalar mesons: in search of the lightest glueball
Creators: name: Ochs, Wolfgang
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: According to the QCD expectations the lightest glueball should be a scalar particle (J^{PC}=0^{++}). Different scenarios have been considered for a classification of these states but -- despite considerable progress in recent years -- the experimental basis for various parameters is still rather weak. We present a new analysis of the elastic and charge exchange pi pi scattering between 1000 and 1800 MeV. A unique solution is selected which shows clear evidence for f_0(1500) and a broad state (σor ``f_0(1000)''), but there is no evidence for f_0(1370) at a level of \gtrsim 10% branching ratio to pi pi. Arguments in favour of the broad state to be a glueball are summarized.

description: The Groverian measures are analytically computed in various types of three-qubit states. The final results are also expressed in terms of local-unitary invariant quantities in each type. This fact reflects the manifest local-unitary invariance of the Groverian measure. It is also shown that the analytical expressions for various types have correct limits to other types. For some types (type 4 and type 5) we failed to compute the analytical expression of the Groverian measure in this paper. However, from the consideration of local-unitary invariants we have shown that the Groverian measure in type 4 should be independent of the phase factor $ϕ$, which appear in the three-qubit state $|ψ>$. This fact with geometric interpretation on the Groverian measure may enable us to derive the analytical expressions for general arbitrary three-qubit states in near future.

description: We perform micro-rheological experiments with a colloidal bead driven through a viscoelastic worm-like micellar fluid and observe two distinctive shear thinning regimes, each of them displaying a Newtonian-like plateau. The shear thinning behavior at larger velocities is in qualitative agreement with macroscopic rheological experiments. The second process, observed at Weissenberg numbers as small as a few percent, appears to have no analog in macro rheological findings. A simple model introduced earlier captures the observed behavior, and implies that the two shear thinning processes correspond to two different length scales in the fluid. This model also reproduces oscillations which have been observed in this system previously. While the system under macro-shear seems to be near equilibrium for shear rates in the regime of the intermediate Newtonian-like plateau, the one under micro-shear is thus still far from it. The analysis suggests the existence of a length scale of a few micrometres, the nature of which remains elusive.

Korean vowel harmony: an optimality account
Creators: name: Choi, Sohee
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines two aspects of Korean vowel harmony: the identification of the correct harmonizing feature and neutrality in the harmony system. In this study, I investigate the hypothesis that Korean vowel harmony can be described as tongue root harmony and that the neutrality in the harmony system can be accounted for through the interaction of various constraints within the framework of Optimality Theory; the Theory of Constraint Interaction (Prince and Smolensky 1993, McCarthy and Prince 1993) In Chapter One, the basic phenomena and the problems of Korean vowel harmony are presented. Chapter Two discusses the theoretical background of Optimality Theory. The basic claims and motivation for the theory are dealt with in the first section. In the following section, I consider major studies applying this theory, including: syllable theory (Prince and Smolensky 1993); prosodic morphology (McCarthy and Prince 1993, Prince and Smolensky 1993); and vowel harmony (Pulleyblank 1993) . In Chapter Three, the Optimality account of Present—Day Korean and Later Middle Korean is presented. I further discuss Optimality Theory’s treatment of diachronic change in harmony systems. Concluding remarks and areas for further research are given in Chapter Four.

description: We compute the anomalous dimensions of field strength operators Tr F^L in N=4 SYM from an asymptotic nested Bethe ansatz to all-loop order. Starting from the exact solution of the one-loop problem at arbitrary L, we derive a single effective integral equation for the thermodynamic limit of these dimensions. We also include the recently proposed phase factor for the S-matrix of the planar AdS/CFT system. The terms in the effective equation corresponding to, respectively, the nesting and the dressing are structurally very similar. This hints at the physical origin of the dressing phase, which we conjecture to arise from the hidden presence of infinitely many auxiliary Bethe roots describing a non-trivial "filled" structure of the theory's BPS vacuum. We finally show that the mechanism for creating effective nesting/dressing kernels is quite generic by also deriving the integral equation for the all-loop dimension of a certain one-loop so(6) singlet state.

description: We investigate the cosmological stability of light bosonic dark matter carrying a tiny electric charge. In the wave-like regime of high occupation numbers, annihilation into gauge bosons can be drastically enhanced by parametric resonance. The millicharged particle can either be minimally coupled to photons or its electromagnetic interaction can be mediated via kinetic mixing with a massless hidden photon. In the case of a direct coupling current observational constraints on the millicharge are stronger than those arising from parametric resonance. For the (theoretically preferred) case of kinetic mixing large regions of parameter space are affected by the parametric resonance leading at least to a fragmentation of the dark matter field if not its outright destruction.

description: The aim of the present thesis was to develop a first-trimester or combined first- and second-trimester screening algorithm for the prediction of small-for-gestational age (SGA) and late growth-restriction (FGR) fetuses. This was a retrospective study of pregnant women with singleton pregnancy, who attended routine first- second- and third-trimester ultrasound scan. The predictive effectiveness of maternal, first- and second-trimester factors was tested using logistic regression and ROC curve analysis. Based on the results of the research we resulted in a simple model which combines the maternal, first- and second-trimester predictors. Our model can detect an important percentage of fetuses who will develop late FGR, and a higher percentage of those fetuses who will be prenatally classified as late FGR.

Έπειτα από μια σύντομη ιστορική αναδρομή, μελετήσαμε τον τρόπο δράσης του, τις διαγνωστικές και θεραπευτικές εφαρμογές του, αλλά και τις ανεπιθύμητες ενέργειες που προκαλεί. Ο ΔΜΕ αποτελεί μια μέθοδο νευροτροποποίησης, η οποία προσφέρει νέες δυνατότητες στη θεραπεία νευρολογικών και ψυχιατρικών παθήσεων. Όμως, έχουν προκύψει ενδείξεις πως ο ΔΜΕ θα μπορούσε να χρησιμοποιηθεί για άλλους, μη ιατρικούς σκοπούς, όπως η βελτίωση των εγκεφαλικών επιδόσεων.

description: The aim of the present thesis was to understand the functioning of transcranial magnetic stimulation (TMS), as well as the possible risks that may arise from its use. After a brief historical review, we studied its function, its diagnostic and therapeutic applications and the adverse effects it causes. TMS is a neuromodulation technique, which offer new possibilities for the treatment of neurological and psychiatric disorders. But new evidence have shown that TMS could be used for non-medical purposes, such as the improvement of brain performance. This particular use arise so many questions. We reflected upon the ethical dilemmas surrounding the unreasonable of TMS and its financial and social consequences. Finally, we concluded that the current legal framework is inadequate and that new legislation is necessary for the protection of the brain rights

description: The aim of the present thesis was the study of the image of Alexander the Great, as well as of his expeditionary force (the ancient Macedonians), in the series “Historiae Alexandri Magni”, by the Latin historian Quintus Curtius Rufus. The entire spectrum of conclusions of scholars up-to-date, regarding an evaluation of Curtius Rufus’ judgement about Alexander and the Macedonians, has been fully presented. The status of Quintus Curtius Rufus among the rest of historians, who have dealt with the world campaign and the empire of Alexander the Great, has been examined. The topic of imitation of Alexander the Great by many Roman emperors has been discussed and the problem of dating of Historiae has been analyzed to its fullest extent. Finally, the evaluation – in several aspects – of the ancient Macedonians, as well as of Alexander, by Curtius Rufus, has been developed.

description: We investigate the role of odd-odd (with respect to time inversion) couplings in the Skyrme force on collisions of light nuclei, employing a fully three-dimensional numerical treatment without any symmetry restrictions and with modern Skyrme functionals. We demonstrate the necessity of these couplings to suppress spurious spin excitations owing to the spin-orbit force in free translational motion of a nucleus but show that in a collision situation there is a strong spin excitation even in spin-saturated systems which persists in the departing fragments. The energy loss is considerably increased by the odd-odd terms.

description: We revisit the evolutionary scenario for Hot Flasher low-mass structures, where mass loss delays the He flash till the initial phases of their White Dwarf cooling sequence. Our aim has been to test the theoretical results vis-a-vis different assumptions about the efficiency of mass loss. To this purpose, we present evolutionary models covering a fine grid of masses, as obtained assuming a single episode of mass loss in a Red Giant model of 0.86 Mo with Z=0.0015. We find a reasonable agreement with previous evolutionary investigations, showing that for the given metallicity late Hot Flashers are predicted to cover the mass range M=0.4975 to M= 0.4845 Mo, all models igniting the He-flash with a mass of the H-rich envelope as given by about Me=0.00050. The ignition mechanism is discussed in some details, showing the occurrence of a bifurcation in the evolutionary history of stellar structures at the lower mass limit for He ignition. Below such a critical mass, the structures miss the He ignition, cooling down as a Hot Flasher-Manque' He White Dwarfs We predict that these structures will cool down, reaching the luminosity logL/Lo=-1 in a time at the least five times longer than the corresponding cooling time of a normal CO White Dwarf. On very general grounds, one expects that old stellar clusters with a sizeable population of Hot Flasher should likely produce at least a similar amount of slow-cooling He White Dwarfs. According to this result, in a cluster where 20% of Red Giants escape the He burning phase, one expects roughly twice as White Dwarfs than in a normal cluster where all Red Giants undergo their He flash

description: We investigate photon emission from a moving particle in an expanding universe. This process is analogous to the radiation from an accelerated charge in the classical electromagnetic theory. Using the framework of quantum field theory in curved spacetime, we demonstrate that the Wentzel-Kramers-Brillouin (WKB) approximation leads to the Larmor formula for the rate of the radiation energy from a moving charge in an expanding universe. Using exactly solvable models in a radiation-dominated universe and in a Milne universe, we examine the validity of the WKB formula. It is shown that the quantum effect suppresses the radiation energy in comparison with the WKB formula.

We present exact integral expressions for the asymptotic growth constant $z_Λ$ for spanning trees on several lattices. By taking different unit cells in the calculation, many integration identities can be obtained. We also give $z_{Λ(p)}$ on the homeomorphic expansion of $k$-regular lattices with $p$ vertices inserted on each edge.

description: We analyze the collective dynamics of self-propelling particles (spps) which move at small Reynolds numbers including the hydrodynamic coupling to the suspending solvent through numerical simulations. The velocity distribution functions show marked deviations from Gaussian behavior at short times, and the mean-square displacement at long times shows a transition from diffusive to ballistic motion for appropriate driving mechanism at low concentrations. We discuss the structures the spps form at long times and how they correlate to their dynamic behavior.

description: We briefly describe two statistical hadronization models, based respectively on the presence and absence of light quark chemical equilibrium, used to analyze particle yields in heavy ion collisions. We then try to distinguish between these models using $K/π$ fluctuations data. We find that while the non-equilibrium model provides an acceptable description of fluctuations at top SPS and RHIC energies, both models considerably under-estimate fluctuations at low SPS energies.

description: The radiative return is a new method for hadronic cross section measurements at electron-positron colliders, which are operated at a fixed center-of-mass energy. In order to lower the effective hadronic mass M_hadr only such events are taken, in which one of the electrons or positrons has emitted an initial state radiation photon. We present precision measurements of the pion form factor from the Frascati phi-factory DAPHNE with the KLOE experiment and measurements of higher particle multiplicities as well as a measurement of the timelike proton-antiproton form factor from the BaBar experiment at the B-factory PEP-II. These radiative return measurements are compared to results, which are obtained by means of an energy scan, i.e. by means of a systematic variation of the beam energy of the collider. We also report on the impact of these measurements on the hadronic contribution of the anomalous magnetic moment of the muon, which is obtained via a dispersion integral using hadronic cross section data as input.

description: The recently proposed map [arXiv:2011.01415] between the hydrodynamic equations governing the two-dimensional triangular cold-bosonic breathers [Phys. Rev. X 9, 021035 (2019)] and the high-density zero-temperature triangular free-fermionic clouds, both trapped harmonically, perfectly explains the former phenomenon but leaves uninterpreted the nature of the initial ($t=0$) singularity. This singularity is a density discontinuity that leads, in the bosonic case, to an infinite force at the cloud edge. The map itself becomes invalid at times $t<0$. A similar singularity appears at $t = T/4$, where $T$ is the period of the harmonic trap, with the Fermi-Bose map becoming invalid at $t > T/4$. Here, we first map -- using the scale invariance of the problem -- the trapped motion to an untrapped one. Then we show that in the new representation, the solution [arXiv:2011.01415] becomes, along a ray in the direction normal to one of the three edges of the initial cloud, a freely propagating one-dimensional shock wave of a class proposed by Damski in [Phys.~Rev.~A 69, 043610 (2004)]. There, for a broad class of initial conditions, the one-dimensional hydrodynamic equations can be mapped to the inviscid Burgers' equation, which is equivalent to a nonlinear transport equation. More specifically, under the Damski map, the $t=0$ singularity of the original problem becomes, verbatim, the initial condition for the wave catastrophe solution found by Chandrasekhar in 1943 [Ballistic Research Laboratory Report No. 423 (1943)]. At $t=T/8$, our interpretation ceases to exist: at this instance, all three effectively one-dimensional shock waves emanating from each of the three sides of the initial triangle collide at the origin, and the 2D-1D correspondence between the solution of [arXiv:2011.01415] and the Damski-Chandrasekhar shock wave becomes invalid.

description: Magnetic reconnection is one of the most important processes in astrophysical, space and laboratory plasmas. Identifying the structure around the point at which the magnetic field lines break and subsequently reform, known as the magnetic null point, is crucial to improving our understanding reconnection. But owing to the inherently three-dimensional nature of this process, magnetic nulls are only detectable through measurements obtained simultaneously from at least four points in space. Using data collected by the four spacecraft of the Cluster constellation as they traversed a diffusion region in the Earth's magnetotail on 15 September, 2001, we report here the first in situ evidence for the structure of an isolated magnetic null. The results indicate that it has a positive-spiral structure whose spatial extent is of the same order as the local ion inertial length scale, suggesting that the Hall effect could play an important role in 3D reconnection dynamics.

description: Stochastic computing has a long history as an alternative method of performing arithmetic on a computer. While it can be considered an unbiased estimator of real numbers, it has a variance and MSE on the order of $Ω(\frac{1}{N})$. On the other hand, deterministic variants of stochastic computing remove the stochastic aspect, but cannot approximate arbitrary real numbers with arbitrary precision and are biased estimators. However, they have an asymptotically superior MSE on the order of $O(\frac{1}{N^2})$. Recent results in deep learning with stochastic rounding suggest that the bias in the rounding can degrade performance. We proposed an alternative framework, called dither computing, that combines aspects of stochastic computing and its deterministic variants and that can perform computing with similar efficiency, is unbiased, and with a variance and MSE also on the optimal order of $Θ(\frac{1}{N^2})$. We also show that it can be beneficial in stochastic rounding applications as well. We provide implementation details and give experimental results to comparatively show the benefits of the proposed scheme.

description: Η παρούσα μεταπτυχιακή εργασία έχει ως πρωταρχικό της στόχο την ανίχνευση, τη στοιχειοθέτηση και τη διερεύνηση των πεδίων σύγκλισης ανάμεσα στις δύο θεμελιακές σχολές στην ιστορία της τέχνης, την αναπαράσταση και την αφαίρεση. Ένας από τους κεντρικούς της άξονες αποτελείται από την ενδελεχή αποτύπωση και την ανάλυση του πυρήνα και της οντότητας των δύο αυτών κυρίαρχων καλλιτεχνικών ρευμάτων, μέσα από ένα πρίσμα διεπιστημονικής προσέγγισης. Παρόλο όμως που ανατρέχει συχνά στη συνεισφορά και άλλων τομέων όπως η φιλοσοφία ή τα κοινωνικοπολιτικά δεδομένα, είναι πρωτίστως και πάνω από όλα μια μελέτη για τη ζωγραφική και την κατάλυση των ίδιων των ορίων της, με έμφαση στην ανάδειξη του πολυδιάστατου ιστορικού της ρόλου. Βασικό της μέλημα επίσης αποτελεί η προβολή της ανεξάντλητης δυναμικής της ζωγραφικής και του τεράστιου φάσματος των μεταβολών και των μετασχηματισμών της, σε συνδυασμό με την καθοριστική επίδραση των πολλαπλών της αντιφάσεων και αναιρέσεων οι οποίες υποβόσκουν ακόμα και μέσα στις πιο δογματικές της εκφάνσεις.
description: The principal quest of the present critical study is to trace, establish and investigate further the fields of convergence between the two fundamental directions in art history, representation and abstraction. One of its central areas encompasses the description and analysis of the features and the entity of these two dominant art movements through an interdisciplinary approach. But even though it is often referring to the contribution of many fields such as philosophy or social and political circumstances, it is mainly and above all a study about painting and the abolishment of its own limits, with special mention in the designation of the multidimensional historical role of painting. Furthermore, one of its basic concerns is also to point out the inexhaustible dynamic of painting. In addition, it is aiming to emphasize in the huge spectrum of the variations and transformations of painting, in combination with the pivotal influence of the multiple contradictions that underlie even in its most doctrinal aspects.

description: We address the novel task of jointly reconstructing the 3D shape, texture, and motion of an object from a single motion-blurred image. While previous approaches address the deblurring problem only in the 2D image domain, our proposed rigorous modeling of all object properties in the 3D domain enables the correct description of arbitrary object motion. This leads to significantly better image decomposition and sharper deblurring results. We model the observed appearance of a motion-blurred object as a combination of the background and a 3D object with constant translation and rotation. Our method minimizes a loss on reconstructing the input image via differentiable rendering with suitable regularizers. This enables estimating the textured 3D mesh of the blurred object with high fidelity. Our method substantially outperforms competing approaches on several benchmarks for fast moving objects deblurring. Qualitative results show that the reconstructed 3D mesh generates high-quality temporal super-resolution and novel views of the deblurred object.

description: Ο ιός της ποικιλίας Pinot Gris (Grapevine Pinot Gris Virus, GPGV) είναι ένας νεοεμφανιζόμενος ιός που προκαλεί σοβαρά προβλήματα στην παραγωγή των αμπελιών. Σε σύντομο χρονικό διάστημα εντοπίστηκε σε διάφορες χώρες. Στην παρούσα εργασία έγινε ανίχνευση και μοριακός χαρακτηρισμός των απομονώσεων του ιού στην Ελλάδα. Επίσης, αναπτύχθηκε η ιοσοθερμική μέθοδος RT-LAMP για την ανίχνευση του. Συγκριτική αξιολόγηση της RT-PCR με την RT-LAMP έδειξε ότι η πρώτη είναι πιο ευαίσθητη. Ο ιός ανιχνεύτηκε κυρίως σε ξενικές ποικιλίες και σε χαμηλά ποσοστά σε εγχώριες, ενώ ανιχνεύτηκε σε εμβολιασμένες ποικιλίες αλλά ουδέποτε σε αυτόρριζες. Η υψηλή συχνότητά του στις ξενικές ποικιλίες υποδεικνύει ότι ο GPGV πιθανώς εισήλθε στη χώρα μας με το μολυσμένο πολλαπλασιαστικό υλικό. Αλληλούχηση τμήματος των γονιδιακών περιοχών MP/CP και RdRp έδειξε ο ιός εμφανίζει χαμηλή γενετική παραλλακτικότητα. Φυλογενετικές αναλύσεις με τη χρησιμοποίηση των αλληλουχιών και των δύο περιοχών που χαρακτηρίστηκαν στην παρούσα μελέτη κατέταξαν τις Ελληνικές απομονώσεις σε μια ομάδα που περιελάμβανε απομονώσεις του ιού που δεν σχετίζονται με την πρόκληση συμπτωμάτων στα πρέμνα. Συνολικά η παρούσα μελέτη καταδεικνύει την ευρεία διασπορά του GPGV στους Ελληνικούς αμπελώνες ωστόσο απαιτούνται περαιτέρω μελέτες για τη διελεύκανση των παραγόντων που επηρεάζουν την παθογένεια και τη μετάδοσή του στον αγρό.
description: Grapevine Pinot Gris Virus (GPGV) is a newly emerging virus that causes serious problems in the production of grapevine. In a short time it was identified in various grapevine varieties all over the world. The present study focused on the detection and molecular characterization of GPGV isolates in Greek vineyards. Moreover, the isothermal RT-LAMP detection method was developed for its detection. Comparative analysis of RT-PCR and the RT-LAMP assays indicated the first as the most reliable. The virus was detected primarily in foreign cultivars and in low rates in the local ones. In addition it was found only in grafted and not in self-rooted cultivars. The high incidence of GPGV in the foreign cultivars points to its putative introduction in Greece through the infected propagating material. Analsis of partial sequences of the MP / CP and RdRp gene regions demonstrated low levels of genetic variability between GPGV isolates. Phylogenetic analyses of both areas characterized in the present study classified the Greek isolates in one group that included GPGV isolates not correlated with disease symptoms. Overall, the present study revealed the widespread distribution of GPGV in Greek vineyards however further studies are necessary in order to elucidate the factors affecting virus pathogenicity and spread on the field.

description: This paper presents a conceptual design for quantum heat machines using a pair of coupled double quantum dots (DQDs), each DQD with an excess electron to interact, as an working substance. We define a compression ratio as the ratio between the Coulomb couplings which describes the interaction between the electrons during the isochoric processes of the quantum Otto cycle and then we analyse the arising of different regimes of operations of our thermal machine. We also show how we can achieve a classically inconceivable Otto engine, when considering the effects due to the parameters related to the quantum tunneling of a single electron between each individual DQD.
