description: In a companion report, we have derived a method for finding the impedance at high frequencies of vacuum chamber transitions that are short compared to the catch-up distance, in a frequency regime that (in analogy to geometric optics for light) we call the optical regime. In this report we apply the method to various non-axisymmetric geometries such as irises/short collimators in a beam pipe, step-in transitions, step-out transitions, and more complicated transitions of practical importance. Most of our results are analytical, with a few given in terms of a simple one dimensional integral. Our results are compared to wakefield simulations with the time-domain, finite-difference program ECHO, and excellent agreement is found.

description: The characterization of gas in the inner disks around young stars is of particular interest because of its connection to planet formation. In order to study the gas in inner disks, we have obtained high-resolution K-band and M-band spectroscopy of 14 intermediate mass young stars. In sources that have optically thick inner disks, i.e. E(K-L)>1, our detection rate of the ro-vibrational CO transitions is 100% and the gas is thermally excited. Of the five sources that do not have optically thick inner disks, we only detect the ro-vibrational CO transitions from HD 141569. In this case, we show that the gas is excited by UV fluorescence and that the inner disk is devoid of gas and dust. We discuss the plausibility of the various scenarios for forming this inner hole. Our modeling of the UV fluoresced gas suggests an additional method by which to search for and/or place stringent limits on gas in dust depleted regions in disks around Herbig Ae/Be stars.

description: It has been pointed by Hall et al. [1] that matter collinations can be defined by using three different methods. But there arises the question of whether one studies matter collineations by using the ${\cal L}_ξT_{ab}=0$, or ${\cal L}_ξT^{ab}=0$ or ${\cal L}_ξT_a^b=0$. These alternative conditions are, of course, not generally equivalent. This problem has been explored by applying these three definitions to general static spherically symmetric spacetimes. We compare the results with each definition.

description: We report a first-principles study on the geometric, electronic and magnetic properties of V-doped anatase TiO$_{2}$. The DFT+U (Hubbard coefficient) approach predicts semiconductor band structures for Ti$_{1-x}$V$_{x}$O$_{2}$ (x=6.25 and 12.5%), in good agreement with the poor conductivity of samples, while the standard calculation within generalized gradient approximation fails. Theoretical results show that V atoms tend to stay close and result in strong ferromagnetism through superexchange interactions. Oxygen vacancy induced magnetic polaron could produce long-range ferromagnetic interaction between largely separated magnetic impurities. The experimentally observed ferromagnetism in V-doped anatase TiO$_{2}$ at room temperature may originate from a combination of short-range superexchange coupling and long-range bound magnetic polaron percolation.

Baryon-baryon interactions in the SU6 quark model and their applications to light nuclear systems

description: Interactions between the octet-baryons (B8) in the spin-flavor SU6 quark model are investigated in a unified coupled-channels framework of the resonating-group method (RGM). The interaction Hamiltonian for quarks consists of the phenomenological confinement potential, the color Fermi-Breit interaction with explicit flavor-symmetry breaking (FSB), and effective-meson exchange potentials of scalar-, pseudoscalar- and vector-meson types. The model parameters are determined to reproduce the properties of the nucleon-nucleon (NN) system and the low-energy cross section data for the hyperon-nucleon (YN) interactions. The NN phase shifts and many observables for the NN and YN interactions are nicely reproduced. Properties of these B8 B8 interactions are analyzed through the G-matrix calculations. The B8 B8 interactions are then applied to some of few-baryon systems and light Lambda-hypernuclei in a three-cluster Faddeev formalism using two-cluster RGM kernels. An application to the three-nucleon system shows that the quark-model NN interaction can give a sufficient triton binding energy with little room for the three-nucleon force. The hypertriton Faddeev calculation indicates that the attraction of the Lambda N interaction in the 1S0 state is only slightly more attractive than that in the 3S1 state. In the application to the alpha alpha Lambda system, the energy spectrum of 9 Lambda Be is well reproduced using the alpha alpha RGM kernel. The very small spin-orbit splitting of the 9 Lambda Be excited states is also discussed. In the Lambda Lambda alpha Faddeev calculation, the NAGARA event for 6 Lambda Lambda He is found to be consistent with the quark-model Lambda Lambda interaction.

description: The pelthora of software cost estimation models reveals that the prediction of the cost of a new software project is a vital task affecting the well-balanced management of the development process. The present dissertation deals with the introduction of statistical and computational methods for the comparison, improvement and development of software cost estimation models. In this dissertation, the use of statistical simulation tools and graphical tools is proposed in order to compare the alternative models. Moreover, we exploit the relation of EbA method to the nearest neighbor non-parametric regression in order to reduce the prediction error with a resampling procedure. Finally, we propose a semi-parametric model on order to combine the parametric and non-parametric regresssion. In this way, we achieve to produce more accurate estimates of cost

description: In tissues as diverse as amphibian skin and the human airway, the cilia that propel fluid are grouped in sparsely distributed multiciliated cells (MCCs). We investigate fluid transport in this "mosaic" architecture, with emphasis on the trade-offs that may have been responsible for its evolutionary selection. Live imaging of MCCs in embryos of the frog $Xenopus~laevis$ shows that cilia bundles behave as active vortices that produce a flow field accurately represented by a local force applied to the fluid. A coarse-grained model that self-consistently couples bundles to the ambient flow reveals that hydrodynamic interactions between MCCs limit their rate of work so that when the system size is large compared to a single MCC, they best shear the tissue at low area coverage, a result that mirrors findings for other sparse distributions such as cell receptors and leaf stomata.

description: We address the problem of removing correlation from sets of states while preserving as much local quantum information as possible. We prove that states obtained from universal cloning can only be decorrelated at the expense of complete erasure of local information (i.e. information about the copied state). We solve analytically the problem of decorrelation for two qubits and two qumodes (harmonic oscillators in Gaussian states), and provide sets of decorrelable states and the minimum amount of noise to be added for decorrelation.

description: The present Thesis’ ambitious objective was the complete, as possible, clarification of the problem of designing circular elements of reinforced concrete, compact and hollow sections, a landscape so far vague. This is due to the fact that the familiar Regulations focus their attention almost exclusively on elements with rectangular sections and neglect other sections resulting to defective design solutions. Defects and problems were acquainted in the confrontation of designing such elements, since irrational approaches, have been adopted. These defects can be summarized as follows: (a) the design problems for shear force, of circular, compact and hollow, section elements, as well as, (b) the problems of coverage of elements against cracking. Imperative problems are the following: (a) the design problem for bending resulting from the earthquake, (b) the design problem for bending resulting from earthquake with a behavior factor q = the 1 or 1,5 (c) the problem of capacity design of bridges (d) the problem of rigidity of circle section piers and columns, (e) the problem of retrofit of circle section piers and columns, and f) for the elements of circular cross-section, the problem of interrelation of the requirements of shear force traverse reinforcement and confinement. All the above reported problems under investigation, were faced through analytically and experimental research

Υπολογίζεται η ετεροσυσχέτιση και η φασματική πυκνότητα ισχύος. Γίνεται εκτίμηση του μοντέλου της διάρκειας ομιλίας ενός ομιλητή και δημιουργείται βάση από σκηνές με διάλογο και χωρίς διάλογο από ταινίες. Στη συνέχεια πραγματοποιείται κατάτμηση ομιλητών με το κριτήριο πληροφορίας κατά Bayes. Προτάθηκε η εκμετάλλευση της κατανομής της διάρκειας ομιλίας καθώς και η επιλογή των πιο διακριτικών συντελεστών χάσματος σε κλίμακα Mel. Μετασχηματίστηκε το κριτήριο πληροφορίας κατά Bayes μέσω κεντραρίσματος και ταυτόχρονης διαγωνιοποίησης. Η ισοδύναμη μετασχηματισμένη μορφή είναι πιο αποδοτική σε ταχύτητα, μνήμη και υπολογιστική ισχύ από τη συμβατική. Επιπροσθέτως, η μορφή αυτή ελέγχθηκε για το πρόβλημα κατάτμησης σε φθόγγους. Για το πρόβλημα της αναγνώρισης φύλου από ομιλία συναισθηματικώς φορτισμένης πραγματοποιήθηκε εξαγωγή 1418 χαρακτηριστικών. Eπισημειώθηκαν 2 βάσεις συναισθηνατικώς φορτισμένης ομιλίας. Δημιουργήθηκε μία από τις λίγες βάσεις αυθόρμητης συναισθματικώς φορτισμένης ομιλίας από κέντρο εξυπηρέτησης στην ελληνική
description: In this thesis, 3 dialogue detection systems are presented. This is the first effort in the international literature that the audio channel is axclusively exploited. Also, it is the first time that the sleaker utterance duration is estimation. Indicator functions are employed. Cross-corelation and cross power spectral tensity are computed. Part of the MUSLE movie database is developed for this thesis. Next, speaker segmentation using the Bayesian information criterion (BIC) is tested. BIC tests are performed when a speaker change point is most probable to occur. Most efficient features for speaker segmentation are identified. A new BIC formulation is derived by applying centering and simultaneous diagonilization. This formulation is less demanding than standard BIC and found an additional application in phone segmentation. gender classification by processing emotional speech is exploited, creating a large pool of 1418 features. 2 emotional speech databases are annnotated by 6 annotators. Finally, we created one of the few audio databases in grrek with spontaneous emotionally recording

description: The TESS Science Office (TSO) at MIT oversees the operation of the Quick Look Pipeline (QLP) and manages the TESS Object of Interest (TOI) catalog via the TESS Exoplanet Vetter (TEV) webpage. The QLP searches for transiting planets around all stars in TESS Full Frame Images down to T=10.5 mag and provides raw, systematics-removed, and detrended lightcurves for all stars down to T=13.5 mag to the public via the MAST portal.  In this talk we summarize current QLP products and give an overview of recent and ongoing upgrades. We also present a new addition to the TEV of the Threshold Crossing Event (TCE) catalog, where the public will be able to track any transit-like signal through the QLP and TESS-ExoClass vetting to determine why a signal was not promoted to the TOI catalog.

description: (abridged:) The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) surveys the most populated ~5 square degrees of the Taurus star formation region, using the XMM-Newton X-ray observatory to study the thermal structure, variability, and long-term evolution of hot plasma, to investigate the magnetic dynamo, and to search for new potential members of the association. Many targets are also studied in the optical, and high-resolution X-ray grating spectroscopy has been obtained for selected bright sources. The X-ray spectra have been coherently analyzed with two different thermal models (2-component thermal model, and a continuous emission measure distribution model). We present overall correlations with fundamental stellar parameters that were derived from the previous literature. A few detections from Chandra observations have been added. The present overview paper introduces the project and provides the basic results from the X-ray analysis of all sources detected in the XEST survey.Comprehensive tables summarize the stellar properties of all targets surveyed. The survey goes deeper than previous X-ray surveys of Taurus by about an order of magnitude and for the first time systematically accesses very faint and strongly absorbed TMC objects. We find a detection rate of 85% and 98% for classical and weak-line T Tau stars (CTTS resp. WTTS), and identify about half of the surveyed protostars and brown dwarfs. Overall, 136 out of 169 surveyed stellar systems are detected. We describe an X-ray luminosity vs. mass correlation, discuss the distribution of X-ray-to-bolometric luminosity ratios, and show evidence for lower X-ray luminosities in CTTS compared to WTTS. Detailed analysis (e.g., variability, rotation-activity relations, influence of accretion on X-rays) will be discussed in a series of accompanying papers.

description: Density matrices of graphs are combinatorial laplacians normalized to have trace one (Braunstein \emph{et al.} \emph{Phys. Rev. A,} \textbf{73}:1, 012320 (2006)). If the vertices of a graph are arranged as an array, then its density matrix carries a block structure with respect to which properties such as separability can be considered. We prove that the so-called degree-criterion, which was conjectured to be necessary and sufficient for separability of density matrices of graphs, is equivalent to the PPT-criterion. As such it is not sufficient for testing the separability of density matrices of graphs (we provide an explicit example). Nonetheless, we prove the sufficiency when one of the array dimensions has length two (for an alternative proof see Wu, \emph{Phys. Lett. A}\textbf{351} (2006), no. 1-2, 18--22). Finally we derive a rational upper bound on the concurrence of density matrices of graphs and show that this bound is exact for graphs on four vertices.

description: Alloying is an established strategy to tune the properties of bulk compounds for desired applications. With the advent of nanotechnology, the same strategy can be applied to 2D materials for technological applications, like single-layer transistors and solid lubricants. Here we present a systematic analysis of the phase behaviour of substitutional 2D alloys in the Transition Metal Disulphides (TMD) family. The phase behaviour is quantified in terms of a metastability metric and benchmarked against many-body expansion of the energy landscape. We show how the metastability metric can be directly used as starting point for setting up rational search strategies in phase space, thus allowing for targeted further computational prediction and analysis of properties. The results presented here also constitute a useful guideline for synthesis of TMDs binary alloys via a range of synthesis techniques.

description: We apply the effective field theory definition of Minimal Flavour Violation (MFV) to the MSSM. We explicitly show how, by this definition, the new sources of flavour and CP violation present in the MSSM become functions of the SM Yukawa couplings, and cannot be simply set to zero, as is common wisdom in phenomenological MSSM studies that assume MFV. We apply our approach to the MSSM Delta B = 2 Hamiltonian at low tan(beta). The limit of MFV amounts to a striking increase in the predictivity of the model. In particular, SUSY corrections to meson-antimeson mass differences Delta M(d,s) are always found to be positive with respect to the SM prediction. This feature is due to an interesting interplay between chargino and gluino box diagrams (the dominant contributions) in the different mass regimes one can consider. Finally, we point out that, due to the presence of gluinos, the MFV MSSM does not belong -- even at low tan(beta) -- to the class of models with the so-called `constrained' MFV (CMFV), in which only the SM operator (V-A)x(V-A) contributes to Delta M(d,s). Consequently, for the MSSM and in the general case of MFV, one should not use the Universal Unitarity Triangle (UUT), relevant for CMFV models, but a MFV-UT constructed from beta(psi KS) and |V(ub)| or gamma from tree level decays. In particular, with the measured value of beta(psi KS), MFV implies a testable correlation between |V(ub)| and gamma. With the present high value of |V(ub)|, MFV favours gamma > 80 degrees.

Dilepton production from a viscous QGP

subject: FOS: Physical sciences

description: This work calculates the first correction to the leading order qq dilepton production rates due to shear viscosity in an expanding gas. The modified rates are integrated over the space-time history of a viscous hydrodynamic simulation of RHIC collisions. The net result is a {\em hardening} of $q_\perp$ spectrum with the magnitude of the correction increasing with invariant mass. We argue that a thermal description is reliable for invariant masses less than $M_{max}\approx(2τ_0 T_0^2)/(η/s)$. For reasonable values of the shear viscosity and thermalization time $M_{max}\approx 4.5$ GeV. Finally, the early emission from a viscous medium is compared to emission from a longitudinally free streaming plasma. Qualitative differences in $q_\perp$ spectrum are seen which could be used to extract information on the thermalization time, viscosity to entropy ratio and possibly the thermalization mechanism in heavy-ion collisions.

description: In view of potential applications of magnetic particles in biomedicine and electromagnetic devices, we made use of the classical Stober method base-catalysed hydrolysis and condensation of tetraethoxysilane (TEOS) to encapsulate FeNi nanoparticles within a silica shell. An original stirring system under high power ultrasounds made possible to disperse the otherwise agglomerated particles. Sonication guaranteed particles to remain dispersed during the Stober synthesis and also improved the efficiency of the method. The coated particles are characterized by electron microscopy (TEM) and spectroscopy (EDX) showing a core-shell structure with a uniform layer of silica. Silica-coating does not affect the core magnetic properties. Indeed, all samples are ferromagnetic at 77 K and room temperature and the Curie point remains unchanged. Only the coercive force shows an unexpected non-monotonous dependence on silica layer thickness.

description: This paper explores the application of functional data analysis (FDA) as a means to study the dynamics of software evolution in the open source context. Several challenges in analyzing the data from software projects are discussed, an approach to overcoming those challenges is described, and preliminary results from the analysis of a sample of open source software (OSS) projects are provided. The results demonstrate the utility of FDA for uncovering and categorizing multiple distinct patterns of evolution in the complexity of OSS projects. These results are promising in that they demonstrate some patterns in which the complexity of software decreased as the software grew in size, a particularly novel result. The paper reports preliminary explorations of factors that may be associated with decreasing complexity patterns in these projects. The paper concludes by describing several next steps for this research project as well as some questions for which more sophisticated analytical techniques may be needed.

description: In the presence of a strong $m=2$ component in a rotating galaxy, the phase space structure near corotation is shaped to a large extent by the {\it invariant manifolds} of the short period family of unstable periodic orbits terminating at L$_1$ or L$_2$. The main effect of these manifolds is to create robust {\it phase correlations} among a number of chaotic orbits large enough to support a {\it spiral} density wave outside corotation. The phenomenon is described theoretically by soliton-like solutions of a Sine-Gordon equation. Numerical examples are given in an N-Body simulation of a barred spiral galaxy. In these examples, we demonstrate how the projection of unstable manifolds in configuration space reproduces essentially the entire observed bar-spiral pattern.

description: In this paper, we develop algorithms for joint user scheduling and three types of mmWave link configuration: relay selection, codebook optimization, and beam tracking in millimeter wave (mmWave) networks. Our goal is to design an online controller that dynamically schedules users and configures their links to minimize the system delay. To solve this complex scheduling problem, we model it as a dynamic decision-making process and develop two reinforcement learning-based solutions. The first solution is based on deep reinforcement learning (DRL), which leverages the proximal policy optimization to train a neural network-based solution. Due to the potential high sample complexity of DRL, we also propose an empirical multi-armed bandit (MAB)-based solution, which decomposes the decision-making process into a sequential of sub-actions and exploits classic maxweight scheduling and Thompson sampling to decide those sub-actions. Our evaluation of the proposed solutions confirms their effectiveness in providing acceptable system delay. It also shows that the DRL-based solution has better delay performance while the MAB-based solution has a faster training process.

description: This study examines effects of calibration errors on model assumptions and data--analytic tools in direct calibration assays. These effects encompass induced dependencies, inflated variances, and heteroscedasticity among the calibrated measurements, whose distributions arise as mixtures. These anomalies adversely affect conventional inferences, to include the inconsistency of sample means; the underestimation of measurement variance; and the distributions of sample means, sample variances, and Student's t as mixtures. Inferences in comparative experiments remain largely intact, although error mean squares continue to underestimate the measurement variances. These anomalies are masked in practice, as conventional diagnostics cannot discern irregularities induced through calibration. Case studies illustrate the principal issues.
