description: Importance sampling is a technique that is commonly used to speed up Monte Carlo simulation of rare events. However, little is known regarding the design of efficient importance sampling algorithms in the context of queueing networks. The standard approach, which simulates the system using an a priori fixed change of measure suggested by large deviation analysis, has been shown to fail in even the simplest network setting (e.g., a two-node tandem network). Exploiting connections between importance sampling, differential games, and classical subsolutions of the corresponding Isaacs equation, we show how to design and analyze simple and efficient dynamic importance sampling schemes for general classes of networks. The models used to illustrate the approach include $d$-node tandem Jackson networks and a two-node network with feedback, and the rare events studied are those of large queueing backlogs, including total population overflow and the overflow of individual buffers.

description: In this paper we report a new estimate of the absolute proper motion (PM) of the globular cluster NGC 5139 ($ω$ Cen) as part of the HST large program GO-14118+14662. We analyzed a field 17 arcmin South-West of the center of $ω$ Cen and computed PMs with an epoch span of $\sim$15.1 years. We employed 45 background galaxies to link our relative PMs to an absolute reference-frame system. The absolute PM of the cluster in our field is: $(μ_α\cosδ, μ_δ) = (-3.341 \pm 0.028 , -6.557 \pm 0.043)$ mas yr$^{-1}$. Upon correction for the effects of viewing perspective and the known cluster rotation, this implies that for the cluster center of mass $(μ_α\cosδ, μ_δ) = (-3.238 \pm 0.028, -6.716 \pm 0.043)$ mas yr$^{-1}$. This measurement is direct and independent, has the highest random and systematic accuracy to date, and will provide an external verification for the upcoming Gaia Data Release 2. It also differs from most reported PMs for $ω$ Cen in the literature by more than 5$σ$, but consistency checks compared to other recent catalogs yield excellent agreement. We computed the corresponding Galactocentric velocity, calculated the implied orbit of $ω$ Cen in two different Galactic potentials, and compared these orbits to the orbits implied by one of the PM measurements available in the literature. We find a larger (by about 500 pc) perigalactic distance for $ω$ Cen with our new PM measurement, suggesting a larger survival expectancy for the cluster in the Galaxy.

title: The difference-based equivalent static load method: an improvement of the ESL method’s nonlinear approximation quality

description: Nonlinear dynamic structural optimization is a real challenge, in particular for problems that require the use of explicit solvers, e.g., crash. Here, the number of design variables is typically very limited. A way to overcome this drawback is to use linear auxiliary load cases which are derived from nonlinear dynamic analysis results in order to enable the application of linear static response optimization. The equivalent static load method (ESLM) provides a well-defined procedure to create such linear auxiliary load cases. The main idea here is that after the selection of a number of representative time steps, a set of equivalent static loads (ESLs) is computed for each time step such that the resulting displacement field in the linear static analysis is identical to the respective field in the nonlinear dynamic analysis. Each set of ESLs defines an auxiliary load case, which is used in the linear static response optimization. The crucial point is that the finite element (FE)-model for each auxiliary load case describes the undeformed initial geometry. This can lead to insufficient approximation quality in the linear static system for highly nonlinear problems. To overcome this drawback, a difference-based extension of the ESL method called DiESL has been developed for nonlinear dynamic response optimization problems. Here, the FE-model for each auxiliary load case describes the deformed nonlinear geometry at the respective time, and the corresponding ESLs create only the displacement field leading to the deformed state of the subsequent ESL time step. Consequently, responses in each linear auxiliary load case (corresponding to a time step) are computed as the accumulated sum of the previous linear auxiliary load cases. Furthermore, the linear static response optimization problem consists not only of one but of nT FE-models where nT is the number of selected time steps. Such a multi-model optimization (MMO) can be solved with commercial FE solvers. It turns out that the DiESL approach leads to a significant improvement of the nonlinear approximation quality and faster convergence to the optimum when compared to standard ESLM. This will be demonstrated and discussed based on selected test examples.

description: This paper discusses a text extraction approach to multi-document summarization that builds on single-document summarization methods by using additional, available information about the document set as a whole and the relationships between the documents. Multi-document summarization differs from single in that the issues of compression, speed, redundancy and passage selection are critical in the formation of useful summaries. Our approach addresses these issues by using domain-independent techniques based mainly on fast, statistical processing, a metric for reducing redundancy and maximizing diversity in the selected passages, and a modular framework to allow easy parameterization for different genres, corpora characteristics and user requirements.

description: Chiral additives in the nematic liquid crystal can alter the dynamics of point defects moving on a disclination line. They exert a constant force on defects, leading to the bimodal distribution of distances between them at long times. The evolution of the system of defects in the presence of chiral additives provides a very direct proof of the existence of repulsive forces between the defects at large distances. We find that addition of a sufficient amount of chiral compound removes all point defects from the system. The process is studied in the system of 8CB (4-n-octyl-4 '-cyanobiphenyl) doped with the chiral compound S811 (from Merck Co.) and in the computer simulations.

description: In this paper, we review recent advances in the Continuous Fractional Component Monte Carlo (CFCMC) methodology and present a historic overview of the most important developments that have led to this method. The CFCMC method has gained attention for Monte Carlo simulations of adsorption at high loading, and phase and reaction equilibria of dense systems. It has recently been extended to reactive systems. The main features of the CFCMC method are: (1) Increased molecule exchange efficiency between different phases in single and multicomponent (reactive) systems, which improves the efficiency and accuracy of phase equilibria simulations at high densities; (2) Direct calculation of the chemical potential from a single simulation; (3) Direct calculation of partial molar properties from a single simulation. The developed simulation techniques are incorporated in the open-source molecular simulation software Brick-CFCMC.
Multi-Attribute Supply Chain Negotiation: Coordinating Reverse Auctions Subject to Finite Capacity Considerations

description: Reverse auctions offer the prospect of more efficiently matching suppliers and producers in the face of changing market conditions. Prior research has generally ignored the temporal and finite capacity constraints under which reverse auctioneers typically operate. In this paper, we consider the problem faced by a manufacturer (or service provider) that needs to fulfill a number of customer orders, each requiring a possibly different combination of components (or services). The manufacturer can procure these components or services from a number of possible suppliers through multi-attribute reverse auctions. Bids submitted by prospective suppliers include a price and a delivery date. The reverse auctioneer has to select a combination of supplier bids that will maximize its overall profit, taking into account its own finite capacity and the prices and delivery dates offered by different suppliers for the same components/services. The manufacturer’s profit is determined by the revenue generated by the products it sells, the cost of the components/services it purchases, as well as late delivery penalties it incurs if it fails to deliver products/services in time to its own customers. We provide a formal model of this important class of problems, discuss its complexity and introduce rules that can be used to efficiently prune the resulting search space. We also introduce a branch-and-bound algorithm that takes advantage of these pruning rules along with two heuristic search procedures. Computational results are presented that evaluate the performance of our heuristic procedures under different conditions both in terms of computational requirements and distance from the optimum. Our experiments show that taking into account finite capacity considerations can significantly improve the manufacturer’s bottom line, thereby confirming the importance of these constraints and the effectiveness of our search heuristics.

This consumerist culture is probably strengthening the philosophy of "get on, get honour and get honest". Can we afford to give up our consumerist culture? the answer is no. What we can do is to at least see that certain basic values like integrity, honesty is inculcated in the educational system. In any society, values, by and large, are inculcated by the parents. They, in turn, are influenced by tradition and religion. After all, religion is nothing but crystallised tradition that upholds the ethical codes of conduct which is in the interest of society will help to make India incredible in a real sense.

The concepts un-derlying Deming's 14 Points can provide a useful lens for considering a wide range of management opportunities and challenges that arise in many complex organizations, especially those that produce or use statistical information.
Quantum oscillations and criticality in a fermionic and bosonic dimer model for the cuprates

description: We study quantum oscillations for a system of fermionic and bosonic dimers and compare the results to those experimentally observed in the cuprate superconductors in their underdoped regime. Based on gauge invariance, we argue that the charge carriers obey the Onsager quantization condition and quantum oscillations take on a Lifshitz-Kosevich form. We obtain the effective mass and find good qualitative agreement with experiments if we tune the model to the point where the observed mass divergence at optimum doping is associated to a van Hove singularity at which four free-dimer Fermi pockets touch pairwise in the interior of the Brillouin zone. The same van Hove singularity leads to a maximum in the d-wave superconducting pairing amplitude when anti-ferromagnetic interactions are included. Our combined results therefore suggest that a quantum critical point separating the underdoped and overdoped regimes is marked by the location of the van Hove saddle point in the fermionic dimer dispersion.

description: We analyse the scattering of sine-Gordon breathers on a square potential well. We show that the scattering process depends not only on the vibration frequency of the breather and its incoming speed but also on its phase as well as the depth and width of the well. We show that the breather can pass through the well and exit with a speed different, sometime larger, from the initial one. It can also be trapped and very slowly decay inside the well or bounce out of the well and go back to where it came from. We also show that the breather can split into a kink and an anti-kink pair when it hits the well.

description: We have studied incommensurate spin ordering in single crystal underdoped La_{2-x}Ba_{x}CuO_{4} with x~0.08, 0.05 and 0.025 using neutron scattering techniques. Static incommensurate magnetic order is observed in the La_{2-x}Ba_{x}CuO_{4} (x=0.05 and 0.025) compounds with ordering wavevectors which are rotated by 45 degree about the commensurate (0.5,0.5,0) position, with respect to that in the superconducting x=0.08 material. These spin modulations are one dimensional in the x=0.05 and 0.025 samples, with ordering wavevectors lying along the orthorhombic b* direction. Such a rotation in the orientation of the static spin ordering as a function of increasing Ba doping, from diagonal to collinear, is roughly coincident with the transition from an insulating to a superconducting ground state and is similar to that observed in the related La_{2-x}Sr_{x}CuO_{4} system. This phenomenon is therefore a generic property of underdoped La-214 cuprates.

description: A Greek weight associated to a parameterized random variable $Z(λ)$ is a random variable $π$ such that $\nabla_λE[ϕ(Z(λ))]=E[ϕ(Z(λ))π]$ for any function $ϕ$. The importance of the set of Greek weights for the purpose of Monte Carlo simulations has been highlighted in the recent literature. Our main concern in this paper is to devise methods which produce the optimal weight, which is well known to be given by the score, in a general context where the density of $Z(λ)$ is not explicitly known. To do this, we randomize the parameter $λ$ by introducing an a priori distribution, and we use classical kernel estimation techniques in order to estimate the score function. By an integration by parts argument on the limit of this first kernel estimator, we define an alternative simpler kernel-based estimator which turns out to be closely related to the partial gradient of the kernel-based estimator of $\mathbb{E}[ϕ(Z(λ))]$. Similarly to the finite differences technique, and unlike the so-called Malliavin method, our estimators are biased, but their implementation does not require any advanced mathematical calculation. We provide an asymptotic analysis of the mean squared error of these estimators, as well as their asymptotic distributions. For a discontinuous payoff function, the kernel estimator outperforms the classical finite differences one in terms of the asymptotic rate of convergence. This result is confirmed by our numerical experiments.

description: Discrete Fourier analysis on the quasar number count, as a function of redshift, $z$, calculated from the Sloan Digital Sky Survey DR6 release appears to indicate that quasars have preferred periodic redshifts with redshift intervals of 0.258, 0.312, 0.44, 0.63, and 1.1. However the same periods are found in the mean of the $zConf$ parameter used to flag the reliability of the spectroscopic measurements. It follows that these redshift periods must result from some selection effect, as yet undetermined. It does not signal any intrinsic (quantized) redshifts in the quasars.

description: In the context of constrained quantum mechanics, reference systems are used to construct relational observables that are invariant under the action of the symmetry group. Upon measurement of a relational observable, the reference system undergoes an unavoidable measurement "back-action" that modifies its properties. In a quantum-gravitational setting, it has been argued that such a back-action may produce effects that are described at an effective level as a form of deformed (or doubly) special relativity. We examine this possibility using a simple constrained system that has been extensively studied in the context of quantum information. While our conclusions support the idea of a symmetry deformation, they also reveal a host of other effects that may be relevant to the context of quantum gravity, and could potentially conceal the symmetry deformation.

description: An application of distributed perception to a novel human/computer interface is presented. A multi-agent network has been applied to the task of modifying a robotic trajectory based on very sparse physical inputs from the user. The user conveys intentions by nudging the end effector, instrumented with a wrist force/torque sensor, in an intuitive manner. In response, each agent interprets these sparse inputs with the aid of a local, fuzzified, heuristic model of a particular parameter or trajectory shape. The agents then independently determine the confidence of their respective findings and distributed arbitration resolves the interpretation through voting.

We considered Bloch domain walls, which are known to display at the surface of thin films flux-closure features called Néel caps. We demonstrated the controlled switching of these caps under a magnetic field, occurring via the propagation of a surface vortex. For this we considered flux-closure states in elongated micron-sized dots, so that only the central domain wall can be addressed, while domains remain unaffected.

description: Quantum entanglement, the essential resource for quantum information processing, has rich dynamics under different environments. Probing different entanglement dynamics typically requires exquisite control of complicated system-environment coupling in real experimental systems. Here, by a simple control of the effective solid-state spin bath in a diamond sample, we observe rich entanglement dynamics, including the conventional asymptotic decay as well as the entanglement sudden death, a term coined for the phenomenon of complete disappearance of entanglement after a short finite time interval. Furthermore, we observe counter-intuitive entanglement rebirth after its sudden death in the same diamond sample by tuning an experimental parameter, demonstrating that we can conveniently control the non-Markovianity of the system-environment coupling through a natural experimental knob. Further tuning of this experimental knob can make the entanglement dynamics completely coherent under the same environmental coupling. Probing of entanglement dynamics, apart from its fundamental interest, may find applications in quantum information processing through control of the environmental coupling.

description: Open contribution systems such as Wikipedia and Linux have been extraordinarily successful at eliciting contributions from many volunteers, but other projects struggle. While research has examined general motivations for contribution, we know little about what triggers contribution at a specific time. In this paper we mine the history of Wikipedia to understand the contribution process in the context of the many competing demands on users’ attention at their computers. In particular, we examine the influence of the visible work of others on the timing and amount of contributions to Wikipedia. Using two different statistical models we show converging evidence of a substantial influence of others’ visible work on triggering contribution.

description: The symmetry and the locality are the two major sources of various nontrivial statements in quantum many-body systems. We demonstrate that, in gapped phases of a U(1) symmetric Hamiltonian with finite-range interactions, the bulk properties such as the expectation value of local operators, the ground state energy and the excitation gap, and the static and low-frequency dynamical responses in general, do not depend on the U(1) phase of the twisted boundary condition in the limit of the large system size. Specifically, their dependence on the twisted angle is exponentially suppressed with the linear dimension of the system. The argument is based on the exponential decay of various types of equal-time correlation functions.

description: In this paper, we address the issue of motion planning for a bipartite class of modular self-reconfiguring robotic system (I-Cubes) that is a collection of active elements providing reconfiguration (3-DOF manipulators called links) and passive elements acting as connectors (cubes). The links, capable of attaching/detaching themselves from/to cubes, can position and orient the cubes. Current solutions for motion planning and reconfiguration of I-Cubes include multi-layered planners that divide a given problem into tractable sub-problems to be evaluated using heuristic methods. The system implementation, its representation in simulation, search algorithms resulting from this representation, and simulation examples are presented.
Defining the Termination of the Asymptotic Giant Branch

description: I suggest a theoretical quantitative definition for the termination of the asymptotic giant branch (AGB) phase and the beginning of the post-AGB phase. I suggest that the transition will be taken to occur when the ratio of the dynamical time scale to the the envelope thermal time scale, Q, reaches its maximum value. Time average values are used for the different quantities, as the criterion does not refer to the short time-scale variations occurring on the AGB and post-AGB, e.g., thermal pulses (helium shell flashes) and magnetic activity. Along the entire AGB the value of Q increases, even when the star starts to contract. Only when a rapid contraction starts does the value of Q start to decrease. This criterion captures the essence of the transition from the AGB to the post AGB phase, because Q is connected to the stellar effective temperature, reaching its maximum value at T~4000-6000 K, it is related to the mass loss properties, and it reaches its maximum value when rapid contraction starts and envelope mass is very low.

description: We propose a motion segmentation algorithm for extracting foreground objects with a pan-tilt camera. Segmentation is achieved by spatio-temporal filtering of the scene to model the background. Temporal filtering is done by a set of modified AR (Auto-Regressive) filters which model the background statistics for a particular view of the scene. Backgrounds from different views of the pan-tilt camera are stitched together into a planar mosaic using a real-time image mosaicing strategy. Our algorithms work in real-time, require no user intervention, and facilitate high-quality video transmission at low bandwidths.
title: Σχεδιασμός πειράματος σεισμικής ανάκλασης στον Κυπαρισσιακό κόλπo

description:   Στόχος της παρούσας διπλωματικής εργασίας είναι η προσομοίωση σεισμικού πειράματος και η παραγωγή συνθετικών δεδομένων ανάκλασης χρησιμοποιώντας γεωλογικό μοντέλο που αντιστοιχεί στην ευρύτερη θαλάσσια περιοχή του Κυπαρισσιακού κόλπου. Έπειτα, από την επεξεργασία των συνθετικών δεδομένων προέκυψαν οι σεισμικές τομές χωροθέτησης οι οποίες υπερτέθηκαν στο μοντέλο τμηματικών ταχυτήτων (Interval Velocity Model).
  Η οριζόντια έκταση του γεωλογικού μοντέλου ήταν 9000 [m] καθώς και το βάθος ορίστηκε στα 7000 [m]. Για την δημιουργία των συνθετικών δεδομένων χρησιμοποιήθηκε ένα σύγχρονο ολοκληρωμένο μαθηματικό λογισμικό πακέτο σε περιβάλλον MatLab και ο αλγόριθμος PSV_Synthetics, ο οποίος αναπτύχθηκε στο Εργαστήριο Εφαρμοσμένης Γεωφυσικής της Σχολής Μηχανικών Ορυκτών Πόρων του Πολυτεχνείου Κρήτης.
  Εν συνέχεια πραγματοποιήθηκε η επεξεργασία των συνθετικών καταγραφών κοινής πηγής σε καταγραφές κοινού ενδιάμεσου σημείου (CMP), διόρθωση κανονικής χρονικής απόκλισης (ΝΜΟ), δημιουργία τομών σεισμικής υπέρθεσης και τέλος χωροθέτησης των σεισμικών τομών σεισμικής υπέρθεσης.
  Εφαρμόστηκαν τρεις μέθοδοι σεισμικής χωροθέτησης:
          • Η μέθοδος χωροθέτησης Kirchhoff
          • Η μέθοδος χωροθέτησης Πεπερασμένων Διαφορών και
          • Η μέθοδος χωροθέτησης Μετατόπισης Φάσης (Phase Shift).
  Βάση των αποτελεσμάτων της επεξεργασίας από τις τρεις μεθόδους χωροθέτησης που εφαρμόστηκαν, αρατηρήθηκε ότι τα βέλτιστα αποτελέσματα προκύπτουν από την μέθοδο χωροθέτησης στο χώρο των συχνοτήτων (Phase Shift). Η χωροθετημένη σεισμική τομή είναι απαλλαγμένη από περιθλάσεις και από την σύγκριση της σεισμικής τομής με το γεωλογικό μοντέλο προκύπτει ότι η σεισμική χωροθέτηση επανατοποθετεί τους ανακλαστήρες στην σωστή τους θέση (ως προς το βάθος και την κλίση τους) και απεικονίζει δομές στο υπέδαφος με πολύ καλή ακρίβεια.

description: A large number of publications are devoted to the problems of diagnosis and treatment of herpes viral infection, which makes it possible to consider it suffi ciently studied.Thus, despite certain advances in the study of the etiology and pathogenesis of herpes infection in the oral cavity, information in pregnant women with herpetic stomatitis is scarce. In this regard, research on this problem is relevant.The effectiveness of herpes simplex therapy depends both on the effectiveness of the specifi c antiviral drugs used and on the fi nal immune corrective effect, which,on the one hand, necessitated the study of the immune status of patients suffering from this disease, on the other hand, the development of various schemes of combined treatment using various specifi c antiviral drugs and immune modulators, and the inclusion of physiotherapeutic methods is considered the safest in this period.

description: We demonstrate the realization of large, fully loaded, arbitrarily-shaped three-dimensional arrays of single atoms. Using holographic methods and real-time, atom-by-atom, plane-by-plane assembly, we engineer atomic structures with up to 72 atoms separated by distances of a few micrometres. Our method allows for high average filling fractions and the unique possibility to obtain defect-free arrays with high repetition rates. These results find immediate application for the quantum simulation of spin Hamiltonians using Rydberg atoms in state-of-the-art platforms, and are very promising for quantum-information processing with neutral atoms.

A Direct Multigrid Poisson Solver for Oct-Tree Adaptive Meshes
Creators: name: Ricker, P. M.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We describe a finite-volume method for solving the Poisson equation on oct-tree adaptive meshes using direct solvers for individual mesh blocks. The method is a modified version of the method presented by Huang and Greengard (2000), which works with finite-difference meshes and does not allow for shared boundaries between refined patches. Our algorithm is implemented within the FLASH code framework and makes use of the PARAMESH library, permitting efficient use of parallel computers. We describe the algorithm and present test results that demonstrate its accuracy.

title: HUBBLE SPACE TELESCOPE/ADVANCED CAMERA FOR SURVEYS MORPHOLOGY OF Ly alpha EMITTERS AT REDSHIFT 5.7 IN THE COSMOS FIELD

description: We present detailed morphological properties of Lyα emitters (LAEs) at z ≈ 5.7 in the COSMOS field based on Hubble Space Telescope Advanced Camera for Surveys (ACS) data. The ACS imaging in the F814W filter covered 85 LAEs of the 119 LAEs identified in the full two square degree field, and 47 LAEs of them are detected in the ACS images. Nearly half of them are spatially extended with a size larger than 0.15 arcsec (∼0.88 kpc at z = 5.7) and up to 0.4 arcsec (∼2.5 kpc at z = 5.7). The others are nearly unresolved compact objects. Two LAEs show double-component structures indicating interaction or merging of building components to form more massive galaxies. By stacking the ACS images of all the detected sources, we obtain a Sersic parameter of n ∼ 0.7 with a half-light radius of 0.13 arcsec (0.76 kpc), suggesting that the majority of ACS detected LAEs have not spheroidal-like but disk-like or irregular light profiles. Comparing ACS F814W magnitudes (I814) with Subaru/Suprime-Cam magnitudes in the NB816, i', and z' bands, we find that the ACS imaging in the F814W band mainly probes UV continuum rather than Lyα line emission. UV continuum sizes tend to be larger for LAEs with larger Lyα emission regions as traced by the NB816 imaging. The nondetection of 38 LAEs in the ACS images is likely due to the fact that their surface brightness is too low both in the UV continuum and Lyα emission. Estimating I814 for the ACS-undetected LAEs from the z' and NB816 magnitudes, we find that 16 of these are probably LAEs with a size larger than 0.15 arcsec in UV continuum. All these results suggest that our LAE sample contains systematically larger LAEs in UV continuum size than those previously studied at z ∼ 6.

description: This toolkit is designed to help promote constructive dialogue in societies and political systems marked by polarisation. It is meant to be used among persons with opposing views on a given topic, where the conversation has escalated to the use of pejorative language and limited listening. Informed by the work of the IFIT brain trusts in Colombia and Mexico, and by IFIT’s Inclusive Narratives Practice Group, the toolkit does not aim to generate consensus or agreement around a given topic. Instead, it promotes viewpoint plurality – the idea that we can and should talk with those whose views are different to our own.

Based on moderated processes in contexts ranging from the classroom to public debates, the tools in the toolkit enable people with opposing viewpoints to use terms that open up engagement, express concerns without insulting, break down assumptions about each other, acknowledge positive aspects of the other’s position, and understand the internal and external limitations opponents face when taking difficult political decisions.

For more information, see IFIT’s practice brief on the process of developing the toolkit and recommendations based on lessons learnt for how to create and use such a resource to enable narrative transformation and manage conflict.

description: A family ${\mathcal A}$ of $k$-subsets of $\{1,2,\dots, N\}$ is a Sidon system if the sumsets $A+B$, $A,B\in \mathcal{A}$ are pairwise distinct. We show that the largest cardinality $F_k(N)$ of a Sidon system of $k$-subsets of $[N]$ satisfies $F_k(N)\le {N-1\choose k-1}+N-k$ and the asymptotic lower bound $F_k(N)=Ω_k(N^{k-1})$. More precise bounds on $F_k(N)$ are obtained for $k\le 3$. We also obtain the threshold probability for a random system to be Sidon for $k\ge 2$.
