description: Anti-D3-branes at the tip of the Klebanov-Strassler solution with D3-charge dissolved in fluxes give rise, in the probe approximation, to a metastable state. The fully back-reacted smeared solution has singular three-form fluxes in the IR, whose presence suggests a stringy resolution by brane polarization a la Polchinski-Strassler. In this paper we show that there is no polarization into anti-D5-branes wrapping the $S^2$ of the conifold at a finite radius. The singularities therefore do not seem to be physical, signaling that antibranes cannot be used to uplift AdS and obtain a very large landscape of de Sitter vacua in string theory.

description: We consider the problem of characterising the generic rigidity of bar-joint frameworks in $\mathbb{R}^d$ in which each vertex is constrained to lie in a given affine subspace. The special case when $d=2$ was previously solved by I. Streinu and L. Theran in 2010. We will extend their characterisation to the case when $d\geq 3$ and each vertex is constrained to lie in an affine subspace of dimension $t$, when $t=1,2$ and also when $t\geq 3$ and $d\geq t(t-1)$. We then point out that results on body-bar frameworks obtained by N. Katoh and S. Tanigawa in 2013 can be used to characterise when a graph has a rigid realisation as a $d$-dimensional body-bar framework with a given set of linear constraints.

description: The paper concerns a result in linear algebra motivated by ideas from tropical geometry. Let $A(t)$ be an $n \times n$ matrix whose entries are Laurent series in $t$. We show that, as $t \to 0$, logarithms of singular values of $A(t)$ approach the invariant factors of $A(t)$. This leads us to suggest logarithms of singular values of an $n \times n$ complex matrix as an analogue of the logarithm map on $(\mathbb{C}^*)^n$ for the matrix group $GL(n, \mathbb{C})$.

description: Let $G$ be an edge-colored graph. The color degree of a vertex $v$ of $G$, is defined as the number of colors of the edges incident to $v$. The color number of $G$ is defined as the number of colors of the edges in $G$. A rainbow triangle is one in which every pair of edges have distinct colors. In this paper we give some sufficient conditions for the existence of rainbow triangles in edge-colored graphs in terms of color degree, color number and edge number. As a corollary, a conjecture proposed by Li and Wang (Color degree and heterochromatic cycles in edge-colored graphs, European J. Combin. 33 (2012) 1958--1964) is confirmed.

The Weak Call-By-Value λ-Calculus is Reasonable for Both Time and Space

description: We study the weak call-by-value $λ$-calculus as a model for computational complexity theory and establish the natural measures for time and space -- the number of beta-reductions and the size of the largest term in a computation -- as reasonable measures with respect to the invariance thesis of Slot and van Emde Boas [STOC~84]. More precisely, we show that, using those measures, Turing machines and the weak call-by-value $λ$-calculus can simulate each other within a polynomial overhead in time and a constant factor overhead in space for all computations that terminate in (encodings) of 'true' or 'false'. We consider this result as a solution to the long-standing open problem, explicitly posed by Accattoli [ENTCS~18], of whether the natural measures for time and space of the $λ$-calculus are reasonable, at least in case of weak call-by-value evaluation. Our proof relies on a hybrid of two simulation strategies of reductions in the weak call-by-value $λ$-calculus by Turing machines, both of which are insufficient if taken alone. The first strategy is the most naive one in the sense that a reduction sequence is simulated precisely as given by the reduction rules; in particular, all substitutions are executed immediately. This simulation runs within a constant overhead in space, but the overhead in time might be exponential. The second strategy is heap-based and relies on structure sharing, similar to existing compilers of eager functional languages. This strategy only has a polynomial overhead in time, but the space consumption might require an additional factor of $\log n$, which is essentially due to the size of the pointers required for this strategy. Our main contribution is the construction and verification of a space-aware interleaving of the two strategies, which is shown to yield both a constant overhead in space and a polynomial overhead in time.

description: We provide a plugin extracting Coq functions of simple polymorphic types to the (untyped) call-by-value $λ$-calculus L. The plugin is implemented in the MetaCoq framework and entirely written in Coq. We provide Ltac tactics to automatically verify the extracted terms w.r.t a logical relation connecting Coq functions with correct extractions and time bounds, essentially performing a certifying translation and running time validation. We provide three case studies: A universal L-term obtained as extraction from the Coq definition of a step-indexed self-interpreter for Ł, a many-reduction from solvability of Diophantine equations to the halting problem of L, and a polynomial-time simulation of Turing machines in L.

description: We propose a rigorous construction of a 1D path collective variable to sample structural phase transformations in condensed matter. The path collective variable is defined in a space spanned by global collective variables that serve as classifiers derived from local structural units. A reliable identification of local structural environments is achieved by employing a neural network based classification. The 1D path collective variable is subsequently used together with enhanced sampling techniques to explore the complex migration of a phase boundary during a solid-solid phase transformation in molybdenum.

This metric is a generalization of the vacuum solution of the Levi-Civita in the general relativity. It describes an isotropic perfect fluid one parameter family of the gravitational configurations which can be interpreted as the exterior metric of a cosmic string. By setting the Gauss-Bonnet coupling parameter to zero, we recover the vacuum solution in the Einstein gravity as well.

description: Esta dissertação tem como objetivo compreender a influência da conspicuidade e suas relações com o arrependimento antecipado influenciando a adoção de novos produtos tecnológicos. A partir de uma revisão teórica da literatura sobre consumo de inovações tecnológicas, analisa-se como a percepção de inovação do indivíduo influencia a conspicuidade com a posse do produto tecnológico, mas também afeta a percepção de risco relacionada a complexidade e inovatividade deste produto, aumentando a percepção de arrependimento futuro que deverá moderar negativamente a relação de conspicuidade com adoção de novas tecnologias. Neste modelo teórico desenvolvido, o cenário inovador tecnológico é voltado a uma criação de ostentação e valor social, percebidos pelo aumento do valor conspícuo do produto para o indivíduo, o que leva ao aumento da intenção em adotar novos produtos. Com o uso da modelagem de equações estruturais pelo método PLS-SEM, desenvolve-se uma análise de forma a identificar, a que nível a percepção de inovação é suficiente para aumentar a conspicuidade, sem aumentar muito o risco e o arrependimento antecipado, tendo assim uma otimização da adoção de novos produtos, o que propõe uma implicação gerencial adequada a produção de novos equipamentos para área de inovação.
Hidden-Symmetry-Protected Topological Semimetals on a Square Lattice

description: We study a two-dimensional fermionic square lattice, which supports the existence of two-dimensional Weyl semimetal, quantum anomalous Hall effect, and $2π$-flux topological semimetal in different parameter ranges. We show that the band degenerate points of the two-dimensional Weyl semimetal and $2π$-flux topological semimetal are protected by two distinct novel hidden symmetries, which both corresponds to antiunitary composite operations. When these hidden symmetries are broken, a gap opens between the conduction and valence bands, turning the system into a insulator. With appropriate parameters, a quantum anomalous Hall effect emerges. The degenerate point at the boundary between the quantum anomalous Hall insulator and trivial band insulator is also protected by the hidden symmetry.

description: Η Μαγνητοεγκεφαλογραφία (Magnetoencephalography - MEG), είναι μια σύγχρονη μη-επεμβατική νευροαπεικονιστική μέθοδος για την ανίχνευση, την ανάλυση και την ερμηνεία του μαγνητικού πεδίου που παράγεται από την ηλεκτρική δραστηριότητα του εγκεφάλου. Στόχος της διπλωματικής εργασίας είναι να αναδείξει τις εγκεφαλικές περιοχές που παρουσιάζουν σημαντικές διαφορές στην λειτουργική συνδεσιμότητα, εξετάζοντας μαγνητοεγκεφαλογραφικά (ΜΕΓ) δεδομένα από δύο ομάδες υποκειμένων, σε κατάσταση ηρεμίας ˙ την μη-απομειωμένη ομάδα (NI - Group) και την ομάδα των αναγνωστικών δυσκολιών (RD - Group). Για να καταστεί αυτό εφικτό, χρησιμοποιείται η μέθοδος της δυναμικής ανάλυσης, παρέχοντας την δυνατότητα λεπτομερούς μελέτης της εγκεφαλικής δραστηριότητας, σε επιμέρους χρονικά στιγμιότυπα. Ωστόσο, πριν την εφαρμογή της, είναι απαραίτητη η ενσωμάτωση μια ολοκληρωμένης διαδικασίας προεπεξεργασίας. Η προεπεξεργασία εφαρμόζεται για κάθε υποκείμενο ξεχωριστά και συνίσταται στην κατάλληλη προετοιμασία των δεδομένων, στην εξαγωγή των ανεξάρτητων συνιστωσών (ICs) της εγκεφαλικής (και μη) δραστηριότητας με χρήση της ICA, στην προτεινόμενη μέθοδο για την ανίχνευση και διόρθωση των ICs που αντιστοιχούν σε διάφορες βιολογικές ή άλλου είδους παρεμβολές (artifacts). Η δυναμική ανάλυση εφαρμόζεται στα διορθωμένα δεδομένα κάθε υποκειμένου, δίνοντας έμφαση σε συνολικά επτά επιμέρους εγκεφαλικούς ρυθμούς και στηρίζεται στην μετρική καθυστέρησης φάσης (PLI) για την κατασκευή των λεγόμενων γράφων λειτουργικής συνδεσιμότητας (FCGs), σε κάθε χρονικό στιγμιότυπο (δυναμικοί γράφοι). Έπειτα υπολογίζονται οι μέσοι δυναμικοί γράφοι (με βάρη τις τιμές του μέσου PLI), λαμβάνοντας τον μέσο όρο των αντίστοιχων στιγμιοτύπων του PLI, σε κάθε ομάδα. Πάνω στους τελευταίους κατασκευάζονται ελάχιστα συνδετικά δέντρα (MSTs), έχοντας ως στόχο την αποκλειστική διατήρηση των ισχυρών συνδέσεων μεταξύ των αισθητήρων. Για την μελέτη των δομικών και λειτουργικών χαρακτηριστικών κάθε MST, χρησιμοποιούνται οι μετρικές BC, ECC και DEG. Στις μετρικές αυτές εφαρμόζεται η στατιστική ανάλυση, σε επίπεδο καναλιών, με στόχο τον εντοπισμό στατιστικά σημαντικών διαφορών μεταξύ του μέσου αριθμού υποκειμένων των δύο ομάδων. Ωστόσο, μόνο οι μετρικές BC και DEG εκδήλωσαν έντονη συγκέντρωση σημαντικών διαφορών. Τέλος, τα αποτελέσματα της δυναμικής ανάλυσης επιβεβαιώνουν ευρήματα από την βιβλιογραφία, αναφορικά με την ύπαρξη διαφορών στα κέντρα του λόγου, στον μηχανισμό της ανάγνωσης αλλά και στις διεργασίες της μνήμης, που επικεντρώνονται στον βήτα εγκεφαλικό ρυθμό και εντοπίζονται κυρίως στην περιοχή μεταξύ του αριστερού βρεγματικού και κροταφικού λοβού, στον προμετωπιαίο λοβό καθώς και σε περιοχές μεταξύ των ινιακών και κροταφικών λοβών, των δύο ημισφαιρίων.
title: Visualization and comparison of topological networks from multiple approaches for cancer prognosis
Creators: name: Τσακανελη Σταυρουλα

Year: 2015

description: The ultimate goal of the genomic revolution, is understanding the genetic causes, the blueprint that specifies the exact ways that genetic components, like genes and proteins, interact to make a complex living system, behind phenotypic characteristics of organisms. Nowadays, genome-wide gene expression technologies have been available and are of great importance in many scientific areas such as clinical prognosis, diagnosis and treatment. This availability has made at least a part of this goal closer and led, both biologists and computational scientists, to introduce a variety of methodological approaches, well suited for both qualitative and quantitative level modeling and simulation, for the analysis of genetic interactions in terms of predicting the genetic and proteomic associations as well as modeling the relationships among the studied genetic components. These approaches have the potential to elucidate the effect of the nature and topology of interactions on the systemic properties of organisms.
In this thesis, we model and process, by implementing two different methodological approaches, the relationships between genes and proteins, in order to examine relationships as well as novel genomic signatures, fundamental and of great significance in the creation of breast cancer and cancer metastasis. These approaches are two different algorithms, HotNet2 and Activity Vector, which create gene interaction subnetworks after processing gene expression data, which have been selected from a larger dataset, and protein-protein interaction networks. Finally, we evaluate the results, for their biological significance and their statistical prediction in an independent dataset.

description: We study the statistical correlation functions for the three-dimensional hydrodynamic turbulence onset when the dynamics is dominated by the pancake-like high-vorticity structures. With extensive numerical simulations, we systematically examine the two-points structure functions (moments) of velocity. We observe formation of the power-law scaling for both the longitudinal and the transversal moments in the same interval of scales as for the energy spectrum. The scaling exponents for the velocity structure functions demonstrate the same key properties as for the stationary turbulence case. In particular, the exponents depend on the order of the moment non-trivially, indicating the intermittency and the anomalous scaling, and the longitudinal exponents turn out to be slightly larger than the transversal ones. When the energy spectrum has power-law scaling close to the Kolmogorov's one, the longitudinal third-order moment shows close to linear scaling with the distance, in line with the Kolmogorov's 4/5-law despite the strong anisotropy.

description: We study the behaviour of a Schelling-class system in which a fraction $f$ of spatially-fixed switching agents is introduced. This new model allows for multiple interpretations, including: (i) random, non-preferential allocation (\textit{e.g.} by housing associations) of given, fixed sites in an open residential system, and (ii) superimposition of social and spatial mobility in a closed residential system.\\ We find that the presence of switching agents in a segregative Schelling-type dynamics can lead to the emergence of intermediate patterns (\textit{e.g.} mixture of patches, fuzzy interfaces) as the ones described in Ref. 1. We also investigate different transitions between segregated and mixed phases both at $f=0$ and along lines of increasing $f$, where the nature of the transition changes.

Sequential measurements of non-commuting observables with quantum controlled interactions

Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The origin of non-classical correlations is difficult to identify since the uncertainty principle requires that information obtained about one observable invariably results in the disturbance of any other non-commuting observable. Here, this problem is addressed by investigating the uncertainty trade-off between measurement errors and disturbance for measurement interactions controlled by the state of a single qubit, where the measurement is described by a quantum coherent superposition of a fully projective measurement and the identity operation. It is shown that the measurement statistics obtained from a quantum controlled measurement of A followed by a projective measurement of B can be explained in terms of a simple combination of resolution and back-action errors acting on an intrinsic joint probability of the non-commuting observables defined by the input state of the system. These intrinsic joint probabilities are consistent with the complex-valued joint probabilities recently observed in weak measurements of quantum systems and provide direct evidence of non-commutativity in the form of imaginary correlations between the non-commuting operators. In quantum controlled measurements, these imaginary correlations can be converted into well-defined contributions to the real measurement statistics, allowing a direct experimental observation of the less intuitive aspects of quantum theory.

description: A linearly constrained framework in $\mathbb{R}^d$ is a point configuration together with a system of constraints which fixes the distances between some pairs of points and additionally restricts some of the points to lie in given affine subspaces. It is globally rigid if the configuration is uniquely defined by the constraint system, and is rigid if it is uniquely defined within some small open neighbourhood. Streinu and Theran characterised generic rigidity of linearly constrained frameworks in $\mathbb{R}^2$ in 2010. We obtain an analagous characterisation for generic global rigidity in $\mathbb{R}^2$. More precisely we show that a generic linearly constrained framework in $\mathbb{R}^2$ is globally rigid if and only if it is redundantly rigid and `balanced'. For generic frameworks which are not balanced, we determine the precise number of solutions to the constraint system whenever the underlying rigidity matroid of the given framework is connected. We also obtain a stress matrix sufficient condition and a Hendrickson type necessary condition for a generic linearly constrained framework to be globally rigid in $\mathbb{R}^d$.

description: Cross-layer protocol design for wireless sensor networking (WSN) has been in the research spotlight,
due to its challenging nature and the current availability of powerful commodity radios. This work proposes TUCCOM,
a cross-layer, multi-frequency channel, interference-agile and mobility-friendly, lightweight WSN protocol that utilizes
various metrics found across the physical, medium access control (MAC) and network layers. Requiring no prior
topology knowledge, TUCCOM can provide ad-hoc networks with self organizing and healing capability. The routing
decisions are distributively made, with distance vector score-based techniques, simple interference detection and
frequency channel hopping. The fundamental mechanisms are discussed and experimental evaluation results on real custom nodes are presented. TUCCOM operates on low-end, low-cost 8-bit micro-controllers, absent of any operating system. In that way, the proposed work can potentially accommodate experimental evaluations of advanced algorithms,
such as network coding or backpressure routing, in interference-rich, ultra-low cost WSN testbeds.

description: The continuous development of hardware performance, in order to achieve higher data bandwidth transfer and integrate peripherals with minimal time and effort, has led to consumer available products capable of more specialized applications. For many years the development of an advanced, smart and reconfigurable electronic imaging system was extremely difficult due to hardware limitations. Modern solid state imagers deliver high image quality with high frame rates, when on the same time, driven by the industry trend for better performing cameras, have promising future development. On the other hand, high performance from the supporting hardware is demanded. This thesis introduces an innovative reconfigurable platform supporting various imagers with different characteristics and capable of controlling imaging parameters. The platform exploits characteristics of the USB Video Class (UVC) to transfer the RAW pixel data captured by the imager, achieving high frame rates. Image quality varies as the platform can exploit modern hardware to process the frames captured by the imager, according to the demands of a given application. As a first step the system is introduced in applications such as low light imaging, real time human vision emulation and image processing with high image quality.

description: A well-known knowledge acquisition method in the field of Formal Concept Analysis (FCA) is attribute exploration. It is used to reveal dependencies in a set of attributes with help of a domain expert. In most applications no single expert is capable (time- and knowledge-wise) of exploring the knowledge domain alone. However, there is up to now no theory that models the interaction of multiple experts for the task of attribute exploration with incomplete knowledge. To this end, we to develop a theoretical framework that allows multiple experts to explore domains together. We use a representation of incomplete knowledge as three-valued contexts. We then adapt the corresponding version of attribute exploration to fit the setting of multiple experts. We suggest formalizations for key components like expert knowledge, interaction and collaboration strategy. In particular, we define an order that allows to compare the results of different exploration strategies on the same task with respect to their information completeness. Furthermore we discuss other ways of comparing collaboration strategies and suggest avenues for future research.

title: Love's Political Potential: Critical Reflections from a Deleuzian Perspective
Creators: name: Bloodworth, Lewis George
Publisher: name: University of Kent

description: Love has often been regarded as merely a private affair occluded from the public domain of the political - love supposedly fostering only an expanded individualism. However, the first essential argument of this thesis is that love is already coextensive with politics - that love is an inescapable force that underpins subjectivity and as such it cannot be excluded or marginalised from discussions of the political - and since it is inescapable, we must grapple with the way it functions at level of subject formation. Therefore, this thesis's central aim is to apply a Deleuzian conceptual framework to challenge the false separation of love and politics that has been established within political theory. Through Deleuze's philosophy of difference we can understand love as process not beholden to identity, we can say that is in fact pedagogical to the degree that love must always navigate the problematic, that which does not fit in love or when love fails the event as the return of desire is fostered. Disappointment in love is central to this process for Deleuze. To radicalise love, we must also confront two central principles of identity and cyclical repetition that ground subjectivity and limit its capacity to embrace alterity: Pleasure and Memory. These subjective modes are derived from the Freudian conception of love vis-a-vi his "pleasure principle", a principle Deleuze works through and challenges, this principle ultimately rendering desire and love as dependent upon a cyclical movement of retroactivity and recollection - love becomes beholden to the return. Deleuze coupled with Freud exposes this essential tension within the core of love and the means for its overcoming. The claim that I defend in this thesis is that love may typically serve as both a conservative force subjectively and politically, but that through a Deleuzian perspective we can see that in fact love's tendency towards repetition as recollection, which is driven by lack, need not sediment identity but rather offer the means for both overcoming love as it is constituted and the means for rethinking what love can do. By applying a Deleuzian perspective we can challenge the existing image of love, which only emphasises its operation at the level of identity and unification, by a repetition of sameness which can lead to love's most violent and traumatic excesses - and we can see love as a process that not only sediments the subject but also fractures it, leading to new potentials and possibilities. Love therefore functions at a micropolitical level beyond the segmentations of molar or macropolitical negativity and conflictual identities, love being a means to undermine identity from within.
Optimal Bound on the Combinatorial Complexity of Approximating Polytopes

description: This paper considers the question of how to succinctly approximate a multidimensional convex body by a polytope. Given a convex body $K$ of unit diameter in Euclidean $d$-dimensional space (where $d$ is a constant) and an error parameter $\varepsilon > 0$, the objective is to determine a convex polytope of low combinatorial complexity whose Hausdorff distance from $K$ is at most $\varepsilon$. By combinatorial complexity we mean the total number of faces of all dimensions. Classical constructions by Dudley and Bronshteyn/Ivanov show that $O(1/\varepsilon^{(d-1)/2})$ facets or vertices are possible, respectively, but neither achieves both bounds simultaneously. In this paper, we show that it is possible to construct a polytope with $O(1/\varepsilon^{(d-1)/2})$ combinatorial complexity, which is optimal in the worst case. Our result is based on a new relationship between $\varepsilon$-width caps of a convex body and its polar body. Using this relationship, we are able to obtain a volume-sensitive bound on the number of approximating caps that are "essentially different." We achieve our main result by combining this with a variant of the witness-collector method and a novel variable-thickness layered construction of the economical cap covering.

Bohr's way to defining complementarity

description: We go through Bohr's talk about complementary features of quantum theory at the Volta Conference in September 1927, by collating a manuscript that Bohr wrote in Como with the unpublished stenographic report of his talk. We conclude - also with the help of some unpublished letters - that Bohr gave a very concise speech in September. The formulation of his ideas became fully developed only between the fifth Solvay Conference, in Brussels in October, and early 1928. The unpublished stenographic reports of the Solvay Conference suggest that we reconsider the role that discussions with his colleagues possibly had on Bohr's final presentation of the complementary sides of atomic physics in his 1928 papers.

description: The Moody-Shapere-Wilczek's adiabatic effective Hamiltonian and Lagrangian method is developed further into the matrix effective Hamiltonian (MEH) and Lagrangian (MEL) approach to a parameter-dependent quantum system. The matrix-operator approach formulated in the product integral (PI) provides not only a method to find the wave function efficiently in the MEH approach but also higher order corrections to the effective action systematically in the MEL approach, a la the Magnus expansion and the Kubo cumulant expansion. A coupled quantum system of a light particle of a harmonic oscillator is worked out, and as a by-product, a new kind of gauge potential (Berry's connection) is found even for nondegenerate cases (real eigenfunctions). Moreover, in the PI formulation the holonomy of the induced gauge potential is related to Schlesinger's exact formula for the gauge field tensor. A superadiabatic expansion is also constructed, and a generalized Dykhne formula, depending on the contour integrals of the homotopy class of complex degenerate points, is rephrased in the PI formulation.

description: We present a tradeoff between leakage and pure dephasing errors for the fluxonium circuit. We show that in the insulating regime, i.e., when the persistent current flowing across the circuit is suppressed, the pure dephasing rate decreases exponentially as the impedance of the circuit is increased. In contrast to this exponential decrease, the qubit remains sufficiently anharmonic so that gates times can still be short, allowing for significant reduction in the computational error rates.

description: A well-known conjecture by Lovász and Plummer from the 1970s asserted that a bridgeless cubic graph has exponentially many perfect matchings. It was solved in the affirmative by Esperet et al. (Adv. Math. 2011). On the other hand, Chudnovsky and Seymour (Combinatorica 2012) proved the conjecture in the special case of cubic planar graphs. In our work we consider random bridgeless cubic planar graphs with the uniform distribution on graphs with $n$ vertices. Under this model we show that the expected number of perfect matchings in labeled bridgeless cubic planar graphs is asymptotically $cγ^n$, where $c>0$ and $γ\sim 1.14196$ is an explicit algebraic number. We also compute the expected number of perfect matchings in (non necessarily bridgeless) cubic planar graphs and provide lower bounds for unlabeled graphs. Our starting point is a correspondence between counting perfect matchings in rooted cubic planar maps and the partition function of the Ising model in rooted triangulations.
