Performance Analysis of Differential Speckle Polarimetry

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: We consider a method for obtaining information on polarization of astronomical objects radiation at diffraction limited resolution - differential speckle polarimetry. As an observable we propose to use averaged cross spectrum of two short-exposure images corresponding to orthogonal polarizations, normalized by averaged power spectrum of one of images. Information on polarization can be extracted if object under study can be described by model with several parameters. We consider two examples: point-like source whose photocenter position depends on orientation of passing polarization and exozodiacal dust disc around a star. In first case difference between photocenter positions can be measured with precision of 8 mirco-arcseconds for 2.5-m telescope and 1.2 micro-arcseconds for 6-m telescope for object V=13. For second example method allows detection of discs around central star of V=1 with fractional luminosities of 1.8E-5 and 5.6E-6 for 2.5-m and 6-m telescope, respectively.

description: We show that a closed orientable 3--dimensional manifold admits a round fold map into the plane, i.e. a fold map whose critical value set consists of disjoint simple closed curves isotopic to concentric circles, if and only if it is a graph manifold, generalizing the characterization for simple stable maps into the plane. Furthermore, we also give a characterization of closed orientable graph manifolds that admit directed round fold maps into the plane, i.e.\ round fold maps such that the number of regular fiber components of a regular value increases toward the central region in the plane.

description: Security of a storage device against a tampering adversary has been a well-studied topic in classical cryptography. Such models give black-box access to an adversary, and the aim is to protect the stored message or abort the protocol if there is any tampering. In this work, we extend the scope of the theory of tamper detection codes against an adversary with quantum capabilities. We consider encoding and decoding schemes that are used to encode a $k$-qubit quantum message $\vert m\rangle$ to obtain an $n$-qubit quantum codeword $\vert {ψ_m} \rangle$. A quantum codeword $\vert {ψ_m} \rangle$ can be adversarially tampered via a unitary $U$ from some known tampering unitary family $\mathcal{U}_{\mathsf{Adv}}$ (acting on $\mathbb{C}^{2^n}$). Firstly, we initiate the general study of \emph{quantum tamper detection codes}, which detect if there is any tampering caused by the action of a unitary operator. In case there was no tampering, we would like to output the original message. We show that quantum tamper detection codes exist for any family of unitary operators $\mathcal{U}_{\mathsf{Adv}}$, such that $\vert\mathcal{U}_{\mathsf{Adv}} \vert < 2^{2^{αn}}$ for some constant $α\in (0,1/6)$; provided that unitary operators are not too close to the identity operator. Quantum tamper detection codes that we construct can be considered to be quantum variants of \emph{classical tamper detection codes} studied by Jafargholi and Wichs~['15], which are also known to exist under similar restrictions. Additionally, we show that when the message set $\mathcal{M}$ is classical, such a construction can be realized as a \emph{non-malleable code} against any $\mathcal{U}_{\mathsf{Adv}}$ of size up to $2^{2^{αn}}$.

description: Travel time estimation is one of the core tasks for the development of intelligent transportation systems. Most previous works model the road segments or intersections separately by learning their spatio-temporal characteristics to estimate travel time. However, due to the continuous alternations of the road segments and intersections in a path, the dynamic features are supposed to be coupled and interactive. Therefore, modeling one of them limits further improvement in accuracy of estimating travel time. To address the above problems, a novel graph-based deep learning framework for travel time estimation is proposed in this paper, namely Spatio-Temporal Dual Graph Neural Networks (STDGNN). Specifically, we first establish the node-wise and edge-wise graphs to respectively characterize the adjacency relations of intersections and that of road segments. In order to extract the joint spatio-temporal correlations of the intersections and road segments, we adopt the spatio-temporal dual graph learning approach that incorporates multiple spatial-temporal dual graph learning modules with multi-scale network architectures for capturing multi-level spatial-temporal information from the dual graph. Finally, we employ the multi-task learning approach to estimate the travel time of a given whole route, each road segment and intersection simultaneously. We conduct extensive experiments to evaluate our proposed model on three real-world trajectory datasets, and the experimental results show that STDGNN significantly outperforms several state-of-art baselines.

description: Recently, unconventional superconductivity having a zero-bias conductance peak is reported in doped topological Dirac semimetal (DSM) with lattice distortion. Motivated by the experiments, we theoretically study the possible symmetry-lowering lattice distortions and their effects on the emergence of unconventional superconductivity in doped topological DSM. We find four types of symmetry-lowering lattice distortions that reproduce the crystal symmetries relevant to experiments from the group-theoretical analysis. Considering inter-orbital and intra-orbital electron density-density interactions, we calculate superconducting phase diagrams. We find that the lattice distortions can induce unconventional superconductivity hosting gapless surface Andreev bound states (SABS). Depending on the lattice distortions and superconducting pairing interactions, the unconventional inversion-odd-parity superconductivity can be either topological nodal superconductivity hosting a flat SABS or topological crystalline superconductivity hosting a gapless SABS. Remarkably, the lattice distortions increase the superconducting critical temperature, which is consistent with the experiments. Our work opens a pathway to explore and control pressure-induced topological superconductivity in doped topological semimetals.

Unified analysis of finite-size error for periodic Hartree-Fock and second order Møller-Plesset perturbation theory

description: Despite decades of practice, finite-size errors in many widely used electronic structure theories for periodic systems remain poorly understood. For periodic systems using a general Monkhorst-Pack grid, there has been no comprehensive and rigorous analysis of the finite-size error in the Hartree-Fock theory (HF) and the second order Møller-Plesset perturbation theory (MP2), which are the simplest wavefunction based method, and the simplest post-Hartree-Fock method, respectively. Such calculations can be viewed as a multi-dimensional integral discretized with certain trapezoidal rules. Due to the Coulomb singularity, the integrand has many points of discontinuity in general, and standard error analysis based on the Euler-Maclaurin formula gives overly pessimistic results. The lack of analytic understanding of finite-size errors also impedes the development of effective finite-size correction schemes. We propose a unified analysis to obtain sharp convergence rates of finite-size errors for the periodic HF and MP2 theories. Our main technical advancement is a generalization of the result of [Lyness, 1976] for obtaining sharp convergence rates of the trapezoidal rule for a class of non-smooth integrands. Our result is applicable to three-dimensional bulk systems as well as low dimensional systems (such as nanowires and 2D materials). Our unified analysis also allows us to prove the effectiveness of the Madelung-constant correction to the Fock exchange energy, and the effectiveness of a recently proposed staggered mesh method for periodic MP2 calculations [Xing, Li, Lin, J. Chem. Theory Comput. 2021]. Our analysis connects the effectiveness of the staggered mesh method with integrands with removable singularities, and suggests a new staggered mesh method for reducing finite-size errors of periodic HF calculations.

Our theory is based on an effective mass model of excitons and trions, parametrized by ab initio calculations and incorporating a proper treatment of screening in two dimensions. The calculated exciton binding energies are in good agreement with high-level many-body computations based on the Bethe-Salpeter equation. Furthermore, our calculations for the more complex trion species compare very favorably with recent experimental measurements, and provide atomistic insight into the microscopic features which determine the trion binding energy.

Symmetry-Protected Solitons and Bulk-Boundary Correspondence in Generalized Jackiw-Rebbi Models

description: We investigate the roles of symmetry and bulk-boundary correspondence in characterizing topological edge states in generalized Jackiw-Rebbi (JR) models. We show that time-reversal ($T$), charge-conjugation ($C$), parity ($P$), and discrete internal field rotation ($Z_n$) symmetries protect and characterize the various types of edge states such as chiral and nonchiral solitons via bulk-boundary correspondence in the presence of the multiple vacua. As two representative models, we consider the JR model composed of a single fermion field having a complex mass and the generalized JR model with two massless but interacting fermion fields. The JR model shows nonchiral solitons with the $Z_2$ rotation symmetry, whereas it shows chiral solitons with the broken $Z_2$ rotation symmetry. In the generalized JR model, only nonchiral solitons can emerge with only $Z_2$ rotation symmetry, whereas both chiral and nonchiral solitons can exist with enhanced $Z_4$ rotation symmetry. Moreover, we find that the nonchiral solitons have $C, P$ symmetries while the chiral solitons do not, which can be explained by the symmetry-invariant lines connecting degenerate vacua. Finally, we find the symmetry correspondence between multiply-degenerate global vacua and solitons such that ${T}$, ${C}$, ${P}$ symmetries of a soliton inherit from global minima that are connected by the soliton, which provides a novel tool for the characterization of topological solitons.

Subjects: subject: Algebraic Topology (math.AT)
subject: FOS: Mathematics

description: Following a suggestion of Hovey and Strickland, we study the category of $K(k) \vee K(k+1) \vee \cdots \vee K(n)$-local spectra. When $k = 0$, this is equivalent to the category of $E(n)$-local spectra, while for $k = n$, this is the category of $K(n)$-local spectra, both of which have been studied in detail by Hovey and Strickland. Based on their ideas, we classify the localizing and colocalizing subcategories, and give characterizations of compact and dualizable objects. We construct an Adams type spectral sequence and show that when $p \gg n$ it collapses with a horizontal vanishing line above filtration degree $n^2+n-k$ at the $E_2$-page for the sphere spectrum. We then study the Picard group of $K(k) \vee K(k+1) \vee \cdots \vee K(n)$-local spectra, showing that this group is algebraic, in a suitable sense, when $p \gg n$. We also consider a version of Gross--Hopkins duality in this category. A key concept throughout is the use of descent.

description: We provide explicit formulas for the integer-valued smooth concordance invariant $\upsilon(K) = Υ_K(1)$ for every 3-braid knot $K$. We determine this invariant, which was defined by Ozsváth, Stipsicz and Szabó, by constructing cobordisms between 3-braid knots and (connected sums of) torus knots. As an application, we show that for positive 3-braid knots $K$ several alternating distances all equal the sum $g(K) + \upsilon(K)$, where $g(K)$ denotes the 3-genus of $K$. In particular, we compute the alternation number, the dealternating number and the Turaev genus for all positive 3-braid knots. We also provide upper and lower bounds on the alternation number and dealternating number of every 3-braid knot which differ by 1.

description: In diesem Beitrag wird anhand biblischer Texte versucht, den Exodus als resonantes und damit wechselseitiges Beziehungsgeschehen anhand der von Hartmut Rosa definierten vier Resonanzachsen, der vertikalen, horizontalen,
diagonalen und jener zu sich selber, zu verstehen: Gott befreit Menschen nicht ohne deren Zutun aus bedrängenden Situationen und sie sind dabei auf die Mithilfe ihrer Mitmenschen angewiesen, die wiederum Solidarität erwarten dürfen. Im liminalen Raum, der nach dem Verlassen der Unterdrückung und der Etablierung im Neuen entsteht, lauern aber auch die Gefahren der Verklärung der Vergangenheit – sprichwörtlich geworden in den „Fleischtöpfen Ägyptens“ – oder des mangelnden Vertrauens in die Helfenden. In den Wüstenerzählungen wird dies mehrfach thematisiert im Konflikt um die Leitungsämter und in den Geschichten des Aufbegehrens gegen die Rettergottheit.
description: This article aims to provide an understanding of the Exodus in Biblical texts as a resonant and thus reciprocal relationship experience based on Hartmut Rosa’s four axes of resonance – vertical, horizontal, diagonal and with oneself: God does
not liberate people without efforts of their own from perilous situations, and they rely on the help of their fellow humans, who in turn can expect solidarity. In the liminal space that is newly created after being freed from oppression and by establishing something new, however, there also lies the danger of transfiguring the past – the proverbial “pots of meat in Egypt” – or not trusting a helping hand. This is addressed several times in the desert stories when talking about the
conflict surrounding leading figures and the rebellion against God the saviour.

Amorphous GdFeCo Films Exhibiting Large and Tunable Perpendicular Magnetic Anisotropy

Year: 2013
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We report the compositional and temperature dependence of magnetic compensation in amorphous GdFeCo films. Magnetic compensation is attributed to the competition between antiferromagnetic coupling of rare-earth with transition-metal (TM) ions and ferromagnetic interaction between the TM ions. The low-Gd region from 20 to 34 at. % was found to exhibit compensation phenomena characterized by a low saturation magnetization and perpendicular magnetic anisotropy (PMA) near the compensation temperature. Compensation temperature was not observed in previously unreported high-Gd region from 52 to 59 at. %, in qualitative agreement with results from recent model calculations. However, low magnetization was achieved at room temperature, accompanied by a large PMA with coercivity reaching ~6.6 kOe. The observed perpendicular magnetic anisotropy of amorphous GdFeCo films probably has a structural origin consistent with certain aspects of the atomic-scale anisotropy. Our findings have broadened the composition range of transition metal-rare earth alloys for designing PMA films, making it attractive for tunable magnetic anisotropy in nanoscale devices.

description: This paper presents a computational framework for quasi-static brittle fracture in three dimensional solids. The paper set outs the theoretical basis for determining the initiation and direction of propagating cracks based on the concept of configurational mechanics, consistent with Griffith's theory. Resolution of the propagating crack by the finite element mesh is achieved by restricting cracks to element faces and adapting the mesh to align it with the predicted crack direction. A local mesh improvement procedure is developed to maximise mesh quality in order to improve both accuracy and solution robustness and to remove the influence of the initial mesh on the direction of propagating cracks. An arc-length control technique is derived to enable the dissipative load path to be traced. A hierarchical hp-refinement strategy is implemented in order to improve both the approximation of displacements and crack geometry. The performance of this modelling approach is demonstrated on two numerical examples that qualitatively illustrate its ability to predict complex crack paths. All problems are three-dimensional, including a torsion problem that results in the accurate prediction of a doubly-curved crack.

description: Given a cardiac-arrest patient being monitored in the ICU (intensive care unit) for brain activity, how can we predict their health outcomes as early as possible? Early decision-making is critical in many applications, e.g. monitoring patients may assist in early intervention and improved care. On the other hand, early prediction on EEG data poses several challenges: (i) earliness-accuracy trade-off; observing more data often increases accuracy but sacrifices earliness, (ii) large-scale (for training) and streaming (online decision-making) data processing, and (iii) multi-variate (due to multiple electrodes) and multi-length (due to varying length of stay of patients) time series. Motivated by this real-world application, we present BeneFitter that infuses the incurred savings from an early prediction as well as the cost from misclassification into a unified domain-specific target called benefit. Unifying these two quantities allows us to directly estimate a single target (i.e. benefit), and importantly, dictates exactly when to output a prediction: when benefit estimate becomes positive. BeneFitter (a) is efficient and fast, with training time linear in the number of input sequences, and can operate in real-time for decision-making, (b) can handle multi-variate and variable-length time-series, suitable for patient data, and (c) is effective, providing up to 2x time-savings with equal or better accuracy as compared to competitors.

description: Efficient exploration of the chemical space to search the candidate drugs that satisfy various constraints is a fundamental task of drug discovery. Advanced deep generative methods attempt to optimize the molecules in the compact latent space instead of the discrete original space, but the mapping between the original and latent spaces is always kept unchanged during the entire optimization process. The unchanged mapping makes those methods challenging to fast adapt to various optimization scenes and leads to the great demand for assessed molecules (samples) to provide optimization direction, which is a considerable expense for drug discovery. To this end, we design a sample-efficient molecular generative method, HelixMO, which explores the scene-sensitive latent space to promote sample efficiency. The scene-sensitive latent space focuses more on modeling the promising molecules by dynamically adjusting the space mapping by leveraging the correlations between the general and scene-specific characteristics during the optimization process. Extensive experiments demonstrate that HelixMO can achieve competitive performance with only a few assessed samples on four molecular optimization scenes. Ablation studies verify the positive impact of the scene-specific latent space, which is capable of identifying the critical characteristics of the promising molecules. We also deployed HelixMO on the website PaddleHelix (https://paddlehelix.baidu.com/app/drug/drugdesign/forecast) to provide drug design service.

description: Die biblische Theologie der Freiheit ist von dem starken Glauben durchdrungen, dass Gott der Befreier ist. In der Moderne wird diese Befreiungstheologie fraglich, weil sie den Verdacht erregt, Menschen würden doch permanent in Abhängigkeit gehalten, wenn sie in ihrer Freiheit auf Gott angewiesen wären. Die Theologie, die diesen Verdacht genährt hat, gehört auf den Prüfstand einer hermeneutisch aufgeschlossenen Exegese, die den ursprünglichen Zusammenhang rekonstruiert. Der Römerbrief des Apostels Paulus belegt ein Konzept, das die Freiheit des Gewissens mit der Freiheit des Glaubens vermittelt. Die Matrix ist eine relationale Anthropologie, die das Ich in den Beziehungen zu anderen Menschen und darin zu Gott charakterisiert sieht. Paulus zeigt, wie in dieser Freiheit ein Ethos universaler Solidarität mit der Klärung einer Erlösungshoffnung einhergeht, die den Horizont menschlicher Freiheit unendlich weitet.
description: The biblical theology of freedom is permeated by the deep faith that God is the liberator of all human beings. In modernity, however, this liberation theology faces the criticism that the so-called liberated would remain in permanent slavery because they depend on God. It is a problematic theology which provokes this question. Therefore, a hermeneutical exegesis which reconstructs the original constellation is required. In Romans, Paul develops a concept which correlates both, the freedom of consciousness all human beings have and the freedom of faith, which is the call of all believers. The matrix is a relational anthropology which characterizes the “I” in his and her proper relations to other human creatures
and therein to God. Paul witnesses how this freedom combines an ethos of universal solidarity with the hope of eschatological salvation, which affirms the freedom of all human beings in the widest dimensions.

description: The question of freedom together with its complex and dialectical manifestations seems to be at the same time unavoidable and impossible and has opened up different interpretative theories throughout the history of philosophical thought. One ideal-typical reading, which by now has becomeclassic, schematically distinguishes two main concepts of the ambivalent experience of freedom, namely positive and negative liberty, which characterized respectively the ancient and the modern individual and collective way of life. While the former emphasizes the universal dimension of the community the individual belongs to, the latter understands freedom as the absence of impositions and as emancipation from the oppressive power of any internal or external despotism. This contribution aims to historically contextualize these two positions, showing their ambivalences and exceptions, in order to problematize the contemporary “immunitarian” comprehension of freedom invoking ancient practices, in order to rethink
freedom as a necessary political construction in the public sphere.
description: Die Frage nach der Freiheit drängt sich als eine unvermeidbare Frage auf, die gleichzeitig aber – angesichts ihrer komplexen und dialektischen Manifestationen – als unmöglich zu beantworten erscheint. Die Frage hat in der Geschichte des philosophischen Denkens verschiedene interpretative Zugänge erfahren. Eine idealtypische, nahezu klassisch gewordene Lesart unterscheidet schematisch zwei grundlegende Konzepte, nach denen die ambivalente Erfahrung der Freiheit unterteilt werden kann: in positive und negative Freiheit. Mit Hilfe dieser beiden Figuren wird versucht, vorausgegangene und moderne Lebensweisen zu betrachten, und dies sowohl auf individueller als auch auf
gemeinschaftlich-kollektiver Ebene. Während das Konzept der positiven Freiheit vor allem die universelle Dimension der Gemeinschaft betont, welcher das Individuum angehört, ist im negativen Zugang Freiheit vor allem die Absenz von Unterwerfungen: Eine befreiende Struktur zeigt sich in der Emanzipation von unterdrückenden despotischen Mächten sowohl interner als auch externer Natur. Der Beitrag zielt darauf ab, diese beiden Positionen geschichtlich einzuordnen
und deren Ambivalenzen und Ausnahmen zu verdeutlichen, um die gegenwärtige Ausfaltung eines Freiheitsdenkens, das auf eine Immunisierung (vor dem Anderen) abzielt, kritisch anzufragen. Unter Rückbezug auf antike Zugänge zur Konzeption von Freiheit wird die Notwendigkeit verdeutlicht, diese als ein grundlegend politisches Konstrukt in der öffentlichen Sphäre zu verankern.

description: On a 3-dimensional contact manifold with boundary, a bypass attachment is an elementary change of the contact structure consisting in the attachment of a thickened half-disc with a prescribed contact structure along an arc on the boundary. We give a model bypass attachment in which we describe the periodic orbits of the Reeb vector field created by the bypass attachment in terms of Reeb chords of the attachment arc. As an application, we compute the contact homology of a product neighbourhood of a convex surface after a bypass attachment, and the contact homology of some contact structures on solid tori.

description: Interpretability of neural networks and their underlying theoretical behavior remain an open field of study even after the great success of their practical applications, particularly with the emergence of deep learning. In this work, NN2Poly is proposed: a theoretical approach to obtain an explicit polynomial model that provides an accurate representation of an already trained fully-connected feed-forward artificial neural network (a multilayer perceptron or MLP). This approach extends a previous idea proposed in the literature, which was limited to single hidden layer networks, to work with arbitrarily deep MLPs in both regression and classification tasks. NN2Poly uses a Taylor expansion on the activation function, at each layer, and then applies several combinatorial properties to calculate the coefficients of the desired polynomials. Discussion is presented on the main computational challenges of this method, and the way to overcome them by imposing certain constraints during the training phase. Finally, simulation experiments as well as applications to real tabular data sets are presented to demonstrate the effectiveness of the proposed method.
