Complexity of Chordal Conversion for Sparse Semidefinite Programs with Small Treewidth
Creators: name: Zhang, Richard Y.
Publisher: name: arXiv

Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: If a sparse semidefinite program (SDP), specified over $n\times n$ matrices and subject to $m$ linear constraints, has an aggregate sparsity graph $G$ with small treewidth, then chordal conversion will sometimes allow an interior-point method to solve the SDP in just $O(m+n)$ time per-iteration, which is a significant speedup over the $Ω(n^{3})$ time per-iteration for a direct application of the interior-point method. Unfortunately, the speedup is not guaranteed by an $O(1)$ treewidth in $G$ that is independent of $m$ and $n$, as a diagonal SDP would have treewidth zero but can still necessitate up to $Ω(n^{3})$ time per-iteration. Instead, we construct an extended aggregate sparsity graph $\bar{G}\supseteq G$ by forcing each constraint matrix $A_{i}$ to be its own clique in $G$. We prove that a small treewidth in $\bar{G}$ does indeed guarantee that chordal conversion will solve the SDP in $O(m+n)$ time per-iteration, to $ε$-accuracy in at most $O(\sqrt{m+n}\log(1/ε))$ iterations. This sufficient condition covers many successful applications of chordal conversion, including the MAX-$k$-CUT relaxation, the Lovász theta problem, sensor network localization, polynomial optimization, and the AC optimal power flow relaxation, thus allowing theory to match practical experience.

description: It is a wide-spread convention to identify repelling Lagrangian Coherent Structures (LCSs) with ridges of the forward finite-time Lyapunov exponent (FTLE) field, and attracting LCSs with ridges of the backward FTLE. We show that in two-dimensional incompressible flows attracting LCSs appear as ridges of the forward FTLE field, too. This raises the issue of characterization of attracting LCSs from a forward finite-time Lyapunov analysis. To this end, we extend recent results by Haller & Sapsis (2011) [1], regarding the relation between forward and backward maximal and minimal FTLEs, to both the whole finite-time Lyapunov spectrum and to stretch directions. This is accomplished by considering the singular value decomposition (SVD) of the linearized flow map. By virtue of geometrical insights from the SVD, we give a short and direct proof of the main result of Farazmand & Haller (2013) [2], and prove a new characterization of attracting LCSs in forward time for Haller's variational approach to hyperbolic LCSs [3]. We apply these results to the attracting FTLE ridge of the incompressible saddle flow.

description: We study the properties of the quantum information transmission channel that emerges from the quantum dynamics of particles interacting with a black hole horizon. We calculate the quantum channel capacity in two limiting cases where a single-letter capacity is known to exist: the limit of perfectly reflecting and perfectly absorbing black holes. We find that the perfectly reflecting black hole channel is closely related to the Unruh channel and that its capacity is non-vanishing, allowing for the perfect reconstruction of quantum information outside of the black hole horizon. We also find that the complementary channel (transmitting entanglement behind the horizon) is entanglement-breaking in this case, with vanishing capacity. We then calculate the quantum capacity of the black hole channel in the limit of a perfectly absorbing black hole and find that this capacity vanishes, while the capacity of the complementary channel is non-vanishing instead. Rather than inviting a new crisis for quantum physics, this finding instead is in accordance with the quantum no-cloning theorem, because it guarantees that there are no space-like surfaces that contain both the sender's quantum state and the receiver's reconstructed quantum state.

description: Using a recently developed formulation of double field theory in superspace, the graviton, $B$-field, gravitini, dilatini, and Ramond-Ramond bispinor are encoded in a single generalized supervielbein. Duality transformations are encoded as orthosymplectic transformations, extending the bosonic $O(D,D)$ duality group, and these act on all constituents of the supervielbein in an easily computable way. We first review conventional non-abelian T-duality in the Green-Schwarz superstring and describe the dual geometries in the language of double superspace. Since dualities are related to super-Killing vectors, this includes as special cases both abelian and non-abelian fermionic T-duality.
 We then extend this approach to include Poisson-Lie T-duality and its generalizations, including the generalized coset construction recently discussed in arXiv:1912.11036. As an application, we construct the supergeometries associated with the integrable $λ$ and $η$ deformations of the $AdS_5 \times S^5$ superstring. The deformation parameters $λ$ and $η$ are identified with the possible one-parameter embeddings of the supergravity frame within the doubled supergeometry. In this framework, the Ramond-Ramond bispinors are directly computable purely from the algebraic data of the supergroup.

Η υιοθέτηση της φιλοσοφίας και των τεχνικών της Διοίκησης Ολικής Ποιότητας (ΔΟΠ) συνέβαλε προς αυτή την κατεύθυνση και παρείχε τα εφόδια για μια δημόσια διοίκηση που θα εστιάζει τόσο στα αποτελέσματα όσο και στις διαδικασίες με γνώμονα τις αρχές τις αριστείας και με πρωτεύοντα στόχο τη συνεχή εξέλιξη. Στην παρούσα διπλωματική εργασία επιχειρείται μια διεξοδική ανάλυση του Κοινού Πλαισίου Αυτοαξιολόγησης (ΚΠΑ) ως εργαλείου αυτοαξιολόγησης, που δημιουργήθηκε για τα ιδιαίτερα χαρακτηριστικά του δημόσιου τομέα και ήρθε και κάλυψε το κενό για μία τεχνική ΔΟΠ που θα παρείχε στις δημόσιες οργανώσεις ένα απλό, προσιτό και εύχρηστο διαγνωστικό εργαλείο που θα τις βοηθούσε να προσδιορίσουν τα δυνατά τους σημεία, τις περιοχές προς βελτίωση και θα συντελούσε στη συνεχή βελτίωση και καινοτομία μέσω της λήψης βελτιωτικών δράσεων και την ανατροφοδότηση. Η εικοσαετής πλέον χρήση του ΚΠΑ αποδεικνύει ότι οι δημόσιοι οργανισμοί που το εφαρμόζουν αποκομίζουν πλείστα οφέλη για το σύνολο της λειτουργίας τους με μετρήσιμα αποτελέσματα που συμβάλλουν στην καλύτερη λειτουργία και εξέλιξή τους. Θεωρείται όμως σημαντικό να επισημανθεί ότι οι δημόσιες οργανώσεις που το χρησιμοποιούν έρχονται αντιμέτωπες με αρκετές δυσκολίες που χρειάζεται να αντιμετωπίσουν, οι οποίες καταγράφονται και από τη σχετική βιβλιογραφία. Παρόλα αυτά, το ΚΠΑ ως μοντέλο ΔΟΠ έχει εξελιχθεί μέσω των πολλαπλών εκδόσεών του, αφουγκραζόμενο τις επιστημονικές εξελίξεις και κοινωνικές ανάγκες, ώστε να καθίσταται ένα αποτελεσματικό εργαλείο που θα βοηθά τους δημόσιους οργανισμούς αφενός να ξεκινήσουν το ταξίδι τους στην ποιότητα και αφετέρου να ωριμάζουν και να εξελίσσονται ως οργανισμοί ΔΟΠ. Η μελέτη περίπτωσης που αναλύεται αποδεικνύει ότι η αυτοαξιολόγηση με το ΚΠΑ οδηγεί σε καινοτομίες που προσφέρουν επωφελή αποτελέσματα τόσο σε επίπεδο εξοικονόμησης οικονομικών πόρων όσο και στη βελτίωση των διαδικασιών και του επιπέδου ποιότητας των παρεχόμενων υπηρεσιών για το σύνολο της κοινωνίας.

description: Simulating superfluid turbulence using the localized induction approximation in periodic bound- aries produces open-orbit vortices, which make superfluid turbulence unsustainable. Calculating with the fully nonlocal Biot-Savart law prevents the open-orbit state from forming, but also in- creases computation time. We use a truncated Biot-Savart integral to investigate the effects of nonlocality on homogeneous turbulence. We find that including the nonlocal interaction up to the average intervortex spacing prevents this open-orbit state from forming, yielding an accurate model of homogeneous superfluid turbulence with less computation time.

description: We consider generation of dark matter mass via radiative electroweak symmetry breaking in an extension of the conformal Standard Model containing a singlet scalar field with a Higgs portal interaction. Generating the mass from a sequential process of radiative electroweak symmetry breaking followed by a conventional Higgs mechanism can account for less than 35% of the cosmological dark matter abundance for dark matter mass $M_s>80 GeV$. However in a dynamical approach where both Higgs and scalar singlet masses are generated via radiative electroweak symmetry breaking we obtain much higher levels of dark matter abundance. At one-loop level we find abundances of 10%--100% with $106 GeV80 GeV$ detection region of the next generation XENON experiment.

description: A compactness framework is established for approximate solutions to subsonic-sonic flows governed by the steady full Euler equations for compressible fluids in arbitrary dimension. The existing compactness frameworks for the two-dimensional irrotational case do not directly apply for the steady full Euler equations in higher dimensions. The new compactness framework we develop applies for both non-homentropic and rotational flows. One of our main observations is that the compactness can be achieved by using only natural weak estimates for the mass balance and the vorticity, along with the Bernoulli law and the entropy relation, through a more delicate analysis on the phase space. As direct applications, we establish two existence theorems for multidimensional subsonic-sonic full Euler flows through infinitely long nozzles.

description: We study a heterostructure which consists of a topological insulator and a superconductor with a hole. The hole pins a vortex. The system supports a robust Majorana fermion state bound to the vortex core. We investigate the possibility of using scanning tunneling spectroscopy (i) to detect the Majorana fermion in the proposed setup and (ii) to study excited states bound to the vortex core. The Majorana fermion manifests itself as a magnetic-field dependent zero-bias anomaly of the tunneling conductance. Optimal parameters for detecting Majorana fermions have been obtained. In the optimal regime, the Majorana fermion is separated from the excited states by a substantial gap. The number of zero-energy states equals the number of flux quanta in the hole; thus, the strength of the zero-bias anomaly depends on the magnetic field. The lowest energy excitations bound to the core are also studied. The excited states spectrum differs from the spectrum of a typical Abrikosov vortex, providing additional indirect confirmation of the Majorana state observation.

description: In the last century, the Ukrainian-Polish relationship has ranged from strategic, neighbourly cooperation to wide-scale oppression and violence. Despite political and historical attempts to address historical controversies and tragedies, there continue to be diverging meta-narratives on events such as the Volhynian massacres and Operation Vistula, which suggest a protracted conflict. Therefore, this thesis will, first, suggest that representatives of the Ukrainian Greek Catholic Church (UGCC) are particularly well-suited to initiate, facilitate, and guide peacebuilding efforts in the lingering Polish-Ukrainian conflict, and second, make some suggestions of how such peacebuilding activity could take shape. To make these arguments, this study is structured in the following manner. After a thorough description of the academic and societal status quo on the Polish-Ukrainian conflict, three lines of argument will be pursued. First, by means of a qualitative analysis of interviews and focus groups with twenty-eight research participants (Ukrainian experts and representatives of religious communities in Ukraine), it will become apparent that the Polish-Ukrainian conflict is perceived to be unresolved, that there is a need for peacebuilding, that a wish for more meaningful peacebuilding exists, and what kind of peacebuilding is envisioned. Second, through an analysis of religious peacebuilding and peacebuilder characteristics, I will suggest that the UGCC and her representatives, in a variety of ways, align especially well with these characteristics. Third, the possible, future effectiveness of the UGCC and her representatives in the peacebuilding process is not merely a theoretical positum, for the history of the Polish-Ukrainian conflict shows that in people like Metropolitan Andrei Sheptyts’kyi, the UGCC finds an important precedent for such peacebuilding activities. Following these three strands, then, I will conclude with some practical suggestions of how this potential in the UGCC could be actualised.

description: Among other things, we prove the following two topologcal statements about closed hyperbolic 3-manifolds. First, every rational second homology class of a closed hyperbolic 3-manifold has a positve integral multiple represented by an oriented connected closed $π_1$-injectively immersed quasi-Fuchsian subsurface. Second, every rationally null-homologous, $π_1$-injectively immersed oriented closed 1-submanifold in a closed hyperbolic 3-manifold has an equidegree finite cover which bounds an oriented compact $π_1$-injective immersed quasi-Fuchsian subsurface. In part, we exploit techniques developed earlier by Kahn and Markovic about good pants constructions, but we only distill geometric and topological ingredients from their papers so no hard analysis is involved in this paper.

description: Humans describe images in terms of nouns and adjectives while algorithms operate on images represented as sets of pixels. Bridging this gap between how humans would like to access images versus their typical representation is the goal of image parsing, which involves assigning object and attribute labels to pixel. In this paper we propose treating nouns as object labels and adjectives as visual attribute labels. This allows us to formulate the image parsing problem as one of jointly estimating per-pixel object and attribute labels from a set of training images. We propose an efficient (interactive time) solution. Using the extracted labels as handles, our system empowers a user to verbally refine the results. This enables hands-free parsing of an image into pixel-wise object/attribute labels that correspond to human semantics. Verbally selecting objects of interests enables a novel and natural interaction modality that can possibly be used to interact with new generation devices (e.g. smart phones, Google Glass, living room devices). We demonstrate our system on a large number of real-world images with varying complexity. To help understand the tradeoffs compared to traditional mouse based interactions, results are reported for both a large scale quantitative evaluation and a user study.

description: Exploiting quantum mechanics for sensing offers unprecedented possibilities. State of the art proposals for novel quantum sensors often rely on the creation of large superpositions and generally detect a field. However, what is the optimal superposition size for detecting an incident particle (or an incident stream of particles) from a specific direction? This question is nontrivial as, in general, this incident particle will scatter off with varied momenta, imparting varied recoils to the sensor, resulting in decoherence rather than a well defined measurable phase. By considering scattering interactions of directional particulate environments with a system in a quantum superposition, we find that there is an "optimal superposition" size for measuring incoming particles via a relative phase. As a consequence of the anisotropy of the environment, we observe a novel feature in the limiting behaviour of the real and imaginary parts of the system's density matrix, linking the optimality of the superposition size to the wavelength of the scatterer.

description: As part of the EKT project, University College of Teacher Education Vienna has taken on the role of leading in the development of a small private online course (SPOC) on introducing the key In-school placement (ISP) actors - student teachers (prospective teachers), academic mentors (lectures) and school mentors (school teachers, cooperating teachers, mentors) – to the EKT smart system, and engaging with the methodology that would support ISP in the three key areas: 1. The cooperation and collaboration between academic mentors and school teachers. 2. The individualized follow-up of student teachers during in-school placements. 3. The reflective practice of student teachers. Thus, we aim to create a SPOC framework covering ideas and activities that will be useful to student teachers, academic mentors and school mentors during the ISP as well engaging the key actors with the EKT smart system. These cover activities around the key phases of ISP as described in WP3 (Output 6 Educational and technological framework) for academic mentors, school mentors and student teachers. The focus throughout is on capacity building for meaningful professional dialogue and reflective practice. The underpinning purpose of the work is not simply the making of the SPOC to support the EKT smart system, but it is to develop a flexible methodology to enhance professional dialogue, student teachers’ agency and promote an action-oriented reflection among student teachers. The literature and data gathered during WP2 (EKT Output 5 Research report) offered a basis on which to identify sets of the key ideas and concepts that we use to define and develop the framework for the EKT SPOC content and tasks. In summary: the purpose of this Report is to show work in relation to O11 Contents for Academic mentors, School mentors and Student Teachers.

description: We propose a novel stochastic algorithm that randomly samples entire rows and columns of the matrix as a way to approximate an arbitrary matrix function using the power series expansion. This contrasts with existing Monte Carlo methods, which only work with one entry at a time, resulting in a significantly better convergence rate than the original approach. To assess the applicability of our method, we compute the subgraph centrality and total communicability of several large networks. In all benchmarks analyzed so far, the performance of our method was significantly superior to the competition, being able to scale up to 64 CPU cores with remarkable efficiency.

description: We review the literature on the gender gap on concept inventories in physics. Across studies of the most commonly used mechanics concept inventories, the Force Concept Inventory (FCI) and Force and Motion Conceptual Evaluation (FMCE), mens average pretest scores are always higher than womens, and in most cases mens posttest scores are higher as well. The weighted average gender difference on these tests is 13% for pretest scores, 12% for posttest scores, and 6% for normalized gain. This difference is much smaller than the average difference in normalized gain between traditional lecture and interactive engagement (25%), but it is large enough that it could impact the results of studies comparing the effectiveness of different teaching methods. There is sometimes a gender gap on commonly used electromagnetism concept inventories, but it is usually much smaller and sometimes is zero or favors women. The weighted average gender difference on these tests is 3.7% for pretest scores, 8.5% for posttest scores, and 6% for normalized gain. Based on our analysis of 26 published articles, no single factor is sufficient to explain the gap. Several high-profile studies that have claimed to account for or reduce the gender gap have failed to be replicated in subsequent studies, suggesting that isolated claims of explanations of the gender gap should be interpreted with caution. Other factors, such as gender differences in background preparation, scores on different kinds of assessment, and splits between how students respond to test questions when answering for themselves or for a scientist do contribute to a difference between male and female responses, but the size of these differences is smaller than the size of the overall gender gap, suggesting that the gender gap is most likely due to the combination of many small factors rather than any one factor that can easily be modified.

description: Estas guías destacan lo que hemos aprendido de las actividades y la recopilación de datos de LIAISON. El objetivo es ayudar a todos los que las utilizan a mejorar su forma de co-innovar en la agricultura, la silvicultura y el desarrollo rural. LIAISON (Better Rural Innovation: Linking Actors, Instruments and Policies through Networks) es un proyecto multiactor que ha sido financiado dentro de la EIP Agri, una iniciativa lanzada por la Comisión Europea en 2012 con su objetivo de fomentar una agricultura y una silvicultura competitivas y sostenibles que “consigan más y mejor con menos”. El enfoque de la innovación interactiva reúne a una amplia gama de actores públicos y privados de la innovación (agricultores, asesores, investigadores, empresas, ONG, etc.) con conocimientos y experiencia complementarios para valorar, reunir, co-crear y difundir soluciones prácticas a las necesidades reales de los agricultores y silvicultores. Estas necesidades están impulsadas por, y se derivan de, las oportunidades reales y los retos cotidianos a los que se enfrentan los agricultores, los silvicultores y las empresas rurales. Las innovaciones generadas mediante un enfoque interactivo pueden aportar soluciones bien adaptadas a las circunstancias y más fáciles de aplicar.

description: Edge Detection is one of the computationally intensive modules in image analysis. It is used to find important landmarks by identifying a significant change (or “edge”) between pixels and voxels. We present a hybrid Quantum Edge Detection method by improving three aspects of an existing widely referenced implementation, which for our use cases generates incomprehensible results for the type and size of images we are required to process. Our contributions are in the pre- and post-processing (i.e., classical phase) and a quantum edge detection circuit: (1) we use space- filling curves to eliminate image artifacts introduced by the image decomposition, which is required to utilize D-NISQ (Distributed Noisy Intermediate-Scale Quantum) model; (2) we introduce a new decrement permutation circuit and relevant optimizations for mapping realistic images on today’s noise Quantum Processor Unites (QPU); (3) we can improve the encoding circuit fidelity to approximately 70%, reduce the edge detection circuit depth by approximately 11%, and reduce the number of CX gates by approximately 68% to under 100, by using a moderate number of 128 cores for 5-qubit QPUs in the D-NISQ simulations, which are enhanced with realistic noise model from IBM. An evaluation of MRI (Magnetic Resonance Imaging) is underway, and we will report our findings.

description: In this work, we consider a propagating scalar field on Kaluza-Klein-type cosmological background. It is shown that this geometrical description of the Universe resembles - from a Hamiltonian standpoint - a damped harmonic oscillator with mass and frequency, both time-dependents. In this scenario, we construct the squeezed coherent states (SCSs) for the quantized scalar field by employing the invariant operator method of Lewis-Riesenfeld (non-Hermitian) in a non-unitary approach. The non-classicality of SCSs has been discussed by examining the quadrature squeezing properties from the uncertainty principle. Moreover, we compute the probability density, which allows us to investigate whether SCSs can be used to seek traces of extra dimensions. We then analyze the effects of the existence of supplementary space on cosmological particle production in SCSs by considering different cosmological eras.

description: An initial analysis of the financial health of nonprofit organizations in the open research and scholarship ecosystem, focusing on those organizations reporting their financial information to the U.S. Internal Revenue Service (IRS) via the standard Form 990. The goal of the analysis is to apply standard measures of organizational health and well-being and create meaningful baselines for assessing the financial health of organizations in this space. In this report, we lay the foundation for how we intend to begin assessing the organizational and financial performance of nonprofits in the open science and scholarly communication ecosystem to drive more and better targeted investment into the space, with an emphasis on those nonprofit organizations providing tools and technologies that enable research and scholarly communication.

Scalar induced gravity waves from ultra slow-roll Galileon inflation

description: We consider the production of secondary gravity waves in Galileon inflation with an ultra-slow roll (USR) phase and show that the spectrum of scalar-induced gravitational waves (SIGWs) in this case is consistent with the recent NANOGrav 15-year data and with sensitivities of other ground and space-based missions, LISA, BBO, DECIGO, CE, ET, HLVK (consists of aLIGO, aVirgo, and KAGRA), and HLV(03). Thanks to the non-renormalization property of Galileon theory, the amplitude of the large fluctuation is controllable at the sharp transitions between SR and USR regions. We show that the behaviour of the GW spectrum, when one-loop effects are included in the scalar power spectrum, is preserved under a shift of the sharp transition scale with peak amplitude $Ω_{\rm GW}h^2\sim {\cal O}(10^{-6})$, and hence it can cover a wide range of frequencies within ${\cal O}(10^{-9}{\rm Hz} - 10^{7}{\rm Hz})$. An analysis of the allowed mass range for primordial black holes (PBHs) is also performed, where we find that mass values ranging from ${\cal O}(1M_{\odot} - 10^{-18}M_{\odot})$ can be generated over the corresponding allowed range of low and high frequencies.

description: Combination locks are widely used to secure bicycles. We consider a combination lock consisting of adjacent rotating dials with the first nonnegative integers printed on each of them. Assuming that we know the correct combination and we start from an incorrect combination, what is the minimal number of steps to arrive at the correct combination if in each step we are allowed to turn an arbitrary number of adjacent dials once in a common direction? We answer this question using elementary methods and show how this is related to a variation of (multivariate) functions.

description: The purpose of the project is to gain fundamental knowledge about the early development of circadian rhythm, sleep, and activity levels, and to map the typical variation within the broader population. An important component is the development of light-sensitive cells in the retina that regulate the circadian rhythm in adults, known as intrinsically photosensitive retinal ganglion cells (ipRGC). The development of ipRGC cells has never been studied in infants before. Our specific goals are therefore: • To test the hypothesis that ipRGC activation, measured through pupillary light response, is linked to the development of the circadian rhythm. • To examine the individual variation in ipRGC activation, spontaneous fluctuations in autonomic regulation, sleep patterns, temperament, and activity levels, and the relationships between these variables. More information about the preregistration is found in the attached document.
