Skew-symmetric distributions and Fisher information -- a tale of two densities

Year: 2012
Subjects: subject: Statistics Theory (math.ST)

description: Skew-symmetric densities recently received much attention in the literature, giving rise to increasingly general families of univariate and multivariate skewed densities. Most of those families, however, suffer from the inferential drawback of a potentially singular Fisher information in the vicinity of symmetry. All existing results indicate that Gaussian densities (possibly after restriction to some linear subspace) play a special and somewhat intriguing role in that context. We dispel that widespread opinion by providing a full characterization, in a general multivariate context, of the information singularity phenomenon, highlighting its relation to a possible link between symmetric kernels and skewing functions -- a link that can be interpreted as the mismatch of two densities.

description: Teacher education is an essential time for preservice teachers to learn effective assessment practices, particularly formative assessment. If used effectively, formative assessment is a planned process wherein students and teachers reciprocally share and use information generated through instructional and assessment activities to improve and develop agency in their learning. The importance of preparing teachers for effective formative assessment practice is heightened by reports that teachers are underprepared to use it when entering the field and may be under supported in their professional development. In two studies, we examine how teacher education prepares teachers for formative assessment, and how preservice teachers would use assessment with their students.
description: In the first study, using systematic research methodology, we reviewed 70 studies investigating teacher education for formative assessment. Within a theory of action for formative assessment, we categorized approaches, processes, and outcomes of efforts in teacher preparation to prepare teachers for formative assessment. Results from this synthesis provide insight into the features of successful approaches to building skills and mindsets for using formative assessment with students and signify a need for innovations and research on how to better prepare teachers for effective assessment practice.
description: In a second study, a nationwide U.S. sample of elementary preservice teachers (N = 112) across program stages were situated in dilemmas of assessment practice within elementary classrooms as the teacher making planning decisions. We presented information about students and context around their English, science, and math units, then elicited assessment actions they would take with students in the next three lessons, the next lesson, and within a task using a series of prompts. Following analysis of responses, a nested sample of participants (n = 40) were invited to return for a 45-minute semi-structured interview to further probe assessment conceptions, intuitions, and rationales for assessment in their future classrooms. Combining these sources of evidence, we provide teacher educators, program stakeholders, and researchers a nuanced description of how preservice teachers may approach assessment in their own classrooms. This information can be used to adjust how programs guide preservice teachers’ development as quality and equitable assessors.

description: Spin-electronic devices are poised to become part of mainstream microelectronic technology .Downsizing them, however, faces the intrinsic difficulty that as ferromagnets become smaller, it becomes more difficult to stabilize their magnetic moment. Antiferromagnets are much more stable, and thus research on antiferromagnetic spintronics has developed into a fast-growing field. Here, we provide proof of concept data that allows us to expand the area of antiferromagnetic spintronics to the hitherto elusive level of individual molecules. In contrast to all previous work on molecular spintronics, our detection scheme of the molecule's spin state does not rely on a magnetic moment. Instead, we use field-effect transistor devices constituting of an isolated, contacted single-wall carbon nanotube covalently bound to a limited number of molecular antiferromagnets incorporating four Mn(II) or Co(II) ions. Time-dependent quantum transport measurement along the functionalized nanotube show step-like transitions between several distinct current levels, which we attribute to transitions between different antiferromagnetic states of individual molecular complexes grafted on the nanotube. A statistical analysis of the switching events using factorial cumulants indicates that the cobalt complexes switch independently from each other, while a coherent superposition of the antiferromagnetic spin states of the molecules along the nanotube is observed for the manganese complexes. The long coherence time (several seconds at 100 mK) is made possible by the absence of spin and orbital momentum in the relevant states of the manganese complex, while the cobalt complex includes a significant orbital momentum contribution due to the pseudo-octahedral d$^7$ metal centers.

description: Let $\mathcal{L} = -\partial_x^2 - V(x) \partial_y^2$ be the Grushin operator on $\mathbb{R}^2$ with coefficient $V : \mathbb{R} \to [0,\infty)$. Under the sole assumptions that $V(-x) \simeq V(x) \simeq xV'(x)$ and $x^2 |V''(x)| \lesssim V(x)$, we prove a spectral multiplier theorem of Mihlin--Hörmander type for $\mathcal{L}$, whose smoothness requirement is optimal and independent of $V$. The assumption on the second derivative $V''$ can actually be weakened to a Hölder-type condition on $V'$. The proof hinges on the spectral analysis of one-dimensional Schrödinger operators, including universal estimates of eigenvalue gaps and matrix coefficients of the potential.

description: We describe a measurement device principle based on discrete iterations of Bayesian updating of system state probability distributions. Although purely classical by nature, these measurements are accompanied with a progressive collapse of the system state probability distribution during each complete system measurement. This measurement scheme finds applications in analysing repeated non-demolition indirect quantum measurements. We also analyse the continuous time limit of these processes, either in the Brownian diffusive limit or in the Poissonian jumpy limit. In the quantum mechanical framework, this continuous time limit leads to Belavkin equations which describe quantum systems under continuous measurements.

description: The pathogenesis of esophageal disorders is related to the esophageal wall mechanics. Therefore, to understand the underlying fundamental mechanisms behind various esophageal disorders, it is crucial to map the esophageal wall mechanics-based parameters onto physiological and pathophysiological conditions corresponding to altered bolus transit and supraphysiologic IBP. In this work, we present a hybrid framework that combines fluid mechanics and machine learning to identify the underlying physics of the various esophageal disorders and maps them onto a parameter space which we call the virtual disease landscape (VDL). A one-dimensional inverse model processes the output from an esophageal diagnostic device called endoscopic functional lumen imaging probe (EndoFLIP) to estimate the mechanical "health" of the esophagus by predicting a set of mechanics-based parameters such as esophageal wall stiffness, muscle contraction pattern and active relaxation of esophageal walls. The mechanics-based parameters were then used to train a neural network that consists of a variational autoencoder (VAE) that generates a latent space and a side network that predicts mechanical work metrics for estimating esophagogastric junction motility. The latent vectors along with a set of discrete mechanics-based parameters define the VDL and form clusters corresponding to the various esophageal disorders. The VDL not only distinguishes different disorders but can also be used to predict disease progression in time. Finally, we also demonstrate the clinical applicability of this framework for estimating the effectiveness of a treatment and track patient condition after a treatment.

description: Complete 3D simulations of the current quench phase of ITER disruptions are key to predict asymmetric forces acting into the ITER wall. We present for the first time such simulations for ITER mitigated disruptions at realistic Lundquist numbers. For these strongly mitigated disruptions, we find that the edge safety factor remains above 2 and the maximal integral horizontal forces remain below 1 MN. The maximal integral vertical force is found to be 13 MN and arises in a time scale given by the resistive wall time as expected from theoretical considerations. In this respect, the vertical force arises after the plasma current has completely decayed, showing the importance of continuing the simulations also in the absence of plasma current. We conclude that the horizontal wall force rotation is not a concern for these strongly mitigated disruptions in ITER, since when the wall forces form, there are no remaining sources of rotation.

description: Species-rich communities, such as the microbiota or microbial ecosystems, provide key functions for human health and climatic resilience. Increasing effort is being dedicated to design experimental protocols for selecting community-level functions of interest. These experiments typically involve selection acting on populations of communities, each of which is composed of multiple species. If numerical simulations started to explore the evolutionary dynamics of this complex, multi-scale system, a comprehensive theoretical understanding of the process of artificial selection of communities is still lacking. Here, we propose a general model for the evolutionary dynamics of communities composed of a large number of interacting species, described by disordered generalised Lotka-Volterra equations. Our analytical and numerical results reveal that selection for scalar community functions leads to the emergence, along an evolutionary trajectory, of a low-dimensional structure in an initially featureless interaction matrix. Such structure reflects the combination of the properties of the ancestral community and of the selective pressure. Our analysis determines how the speed of adaptation scales with the system parameters and the abundance distribution of the evolved communities. Artificial selection for larger total abundance is thus shown to drive increased levels of mutualism and interaction diversity. Inference of the interaction matrix is proposed as a method to assess the emergence of structured interactions from experimentally accessible measures.

description: The aim of this paper is to deepen the analysis of the asymptotic behavior of the so-called minimal random walk (MRW) using a new martingale approach. The MRW is a discrete-time random walk with infinite memory that has three regimes depending on the location of its two parameters. In the diffusive and critical regimes, we establish new results on the almost sure asymptotic behavior of the MRW, such as the quadratic strong law and the law of the iterated logarithm. In the superdiffusive regime, we prove the almost sure convergence of the MRW, properly normalized, to a nondegenerate random variable. Moreover, we show that the fluctuation of the MRW around its limiting random variable is still Gaussian.

description: We study the momentum and Hamiltonian constraints of vacuum Einstein equations, within the Bowen-York formalism, for two interacting black holes in close separation, with anti-parallel spins and anti-parallel linear momenta. We give an analytical solution using perturbation theory. We also compute the location and the shape of the apparent horizon which generically depend on all the parameters, angles and the separation between the black holes. Our solution only works for distances far away from the black holes. To gain more insight close to the black holes, one has to go to the higher orders in perturbation theory, which is a rather cumbersome process. But the solution presented here can be of some use for numerical computations as the latter should match our result for the described problem.

description: MetaStore is a metadata repository for managing metadata documents. It supports communities in storing metadata documents in a predefined schema. It is therefore an important building block for more precise automated evaluation and/or retrieval of digital objects. With the help of the metadata documents, digital objects can also be evaluated/compared according to content-related aspects. XML and JSON are very common as data formats for such machine-interpretable documents. However, they are only meaningful if they adhere to a certain structure and are correctly filled in. MetaStore supports the use of XML and JSON schema as the definition for the document structure. It allows you to register your own and/or existing schemas in these two formats to ensure that the documents have the appropriate structure. When ingesting metadata documents, the structure is checked and invalid documents are rejected. All valid documents are assigned a persistent identifier and can be automatically indexed for search. Public documents can be harvested via a standardized protocol (OAI-PMH). The supplied web interface also provides a low-threshold entry point for managing documents and also allows documents to be created/edited without additional tools. This work has been supported by the research program ‘Engineering Digital Futures’ of the Helmholtz Association of German Research Centers and the Helmholtz Metadata Collaboration Platform.

description: Using data from the Complete Nearby ($z_{host}<0.02$) sample of Type Ia Supernovae (CNIa0.02), we discover a linear relation between two parameters derived from the $B-V$ color curves of Type Ia supernovae: the "color stretch" $s_{BV}$ and the rising color slope $s_0^*(B-V)$ after the peak, and this relation applies to the full range of $s_{BV}$. The $s_{BV}$ parameter is known to be tightly correlated with the peak luminosity, and especially for "fast decliners" (dim Type Ia supernovae), and the luminosity correlation with $s_{BV}$ is markedly better than with the classic light-curve width parameters such as $Δ{m_{15}(B)}$. Thus our new linear relation can be used to infer peak luminosity from $s_0^*$. Unlike $s_{BV}$ (or $Δ{m_{15}}$), the measurement of $s_0^*(B-V)$ does not rely on the well-determined time of light-curve peak or color maximum, making it less demanding on the light-curve coverage than past approaches.

description: This paper is a study of the electromagnetic radiation at temperature $T$ in a thin slab whose walls are made of a perfect conductor. The two large parallel walls of area $A$ are apart by a distance $d\ll \sqrt{A}$. We take $T$, $A$, and $d$ as thermodynamic parameters, obtaining the free energy from a procedure that involves the integration over the slab of the ensemble average of the stress-energy-momentum tensor calculated long ago by Brown and Maclay. Both thermodynamic regimes $kTd/\hbar c\gg 1$ and $kTd/\hbar c\ll 1$ are fully addressed. We show that certain thermodynamic quantities which are notoriously ill defined (or trivial) in ordinary blackbody thermodynamics are now well defined (or nontrivial) due to presence of boundary conditions at the walls of the slab ("Casimir's effect"). The relationships among such quantities are fully explored and it is speculated that they may be experimentally checked. Stability is addressed, showing that electromagnetic radiation in the slab is thermally stable; but mechanically unstable. We investigate thermodynamic processes where temperature, internal energy, entropy and enthalpy are each taken to be constant, revealing rather atypical behaviors. For example, in sharp contrast with what one would expect from a gas, when $kTd/\hbar c\ll 1$, "free expansion" gives place to "free contraction'' in accordance with the second law of thermodynamics. As a check of consistency of the formulae we remark that various Carnot cycles have been examined and verified that they correctly lead to Carnot's efficiency.

title: Employing optimization in CAE vehicle dynamics
Creators: name: Λελεδακης Αλεξανδρος
Publisher: name: Technical University of Crete
Year: 2014

description: The use of Computer Aided Engineering (CAE) tools from the Conceptual Design stage can lead to reduced production time and cost, while it can also help attribute leaders to more efficiently achieve the desired vehicle specifications.

CAE tools can facilitate engineers to design, modify, calibrate and optimize their designs in an early development phase. Therefore, physical testing during the development process of a new vehicle can be reduced; methods can be developed, which can facilitate physical testing scenarios in virtual environments using simulation software.

Automotive industry is aiming towards vehicle verification using Simulation software rather than physical prototype testing. This thesis aims to develop CAE methods for Vehicle dynamics related to active safety features.

description: From the data on baryon production in heavy-ion collisions it is shown that a set of measurable functions exist, one for each baryon type, that depend exponentially on transverse momenta up to the maximum values detected for all collision energies ranging from the low end of RHIC BES to the high end of CERN LHC. The implied temperatures satisfy a scaling law in collision energy with a universal exponent for all baryon types which is the novel discovery. A self-similar thermal source is implied. Furthermore, it is shown how the scaling behavior depends on centralities. Those features in the data are related to simple properties of light and strange quarks by use of the recombination model. Prediction of $ϕ$ meson production is made and then verified by existing data.

description: A discontinuous Galerkin (DG) method suitable for large-scale astrophysical simulations on Cartesian meshes as well as arbitrary static and moving Voronoi meshes is presented. Most major astrophysical fluid dynamics codes use a finite volume (FV) approach. We demonstrate that the DG technique offers distinct advantages over FV formulations on both static and moving meshes. The DG method is also easily generalized to higher than second-order accuracy without requiring the use of extended stencils to estimate derivatives (thereby making the scheme highly parallelizable). We implement the technique in the AREPO code for solving the fluid and the magnetohydrodynamic (MHD) equations. By examining various test problems, we show that our new formulation provides improved accuracy over FV approaches of the same order, and reduces post-shock oscillations and artificial diffusion of angular momentum. In addition, the DG method makes it possible to represent magnetic fields in a locally divergence-free way, improving the stability of MHD simulations and moderating global divergence errors, and is a viable alternative for solving the MHD equations on meshes where Constrained-Transport (CT) cannot be applied. We find that the DG procedure on a moving mesh is more sensitive to the choice of slope limiter than is its FV method counterpart. Therefore, future work to improve the performance of the DG scheme even further will likely involve the design of optimal slope limiters. As presently constructed, our technique offers the potential of improved accuracy in astrophysical simulations using the moving mesh AREPO code as well as those employing adaptive mesh refinement (AMR).

From gravity to string topology

description: The chain gravity properad introduced earlier by the author acts on the cyclic Hochschild of any cyclic $A_\infty$ algebra equipped with a scalar product of degree $-d$. In particular, it acts on the cyclic Hochschild complex of any Poincare duality algebra of degree $d$, and that action factors through a quotient dg properad $ST_{3-d}$ of ribbon graphs which is in focus of this paper. We show that its cohomology properad $H^\bullet(ST_{3-d})$ is highly non-trivial and that it acts canonically on the reduced equivariant homology $\bar{H}_\bullet^{S^1}(LM)$ of the loop space $LM$ of any simply connected $d$-dimensional closed manifold $M$. By its very construction, the string topology properad $H^\bullet(ST_{3-d})$ comes equipped with a morphism from the gravity properad which is fully determined by the compactly supported cohomology of the moduli spaces $M_{g,n}$ of stable algebraic curves of genus $g$ with marked points. This result gives rise to new universal operations in string topology as well as reproduces in a unified way several known constructions: we show that (i) $H^\bullet(ST_{3-d})$ is also a properad under the properad of involutive Lie bialgebras in degree $3-d$ whose induced action on $\bar{H}_\bullet^{S^1}(LM)$ agrees precisely with the famous purely geometric construction of M. Chas and D. Sullivan, (ii) $H^\bullet(ST_{3-d})$ is a properad under the properad of homotopy involutive Lie bialgebras in degree $2-d$; (iii) E. Getzler's gravity operad injects into $H^\bullet(ST_{3-d})$ implying a purely algebraic counterpart of the geometric construction of C. Westerland establishing an action of the gravity operad on $\bar{H}_\bullet^{S^1}(LM)$.

Analytic families of quantum hyperbolic invariants

Subjects: subject: Geometric Topology (math.GT)

description: We organize the quantum hyperbolic invariants (QHI) of $3$-manifolds into sequences of rational functions indexed by the odd integers $N\geq 3$ and defined on moduli spaces of geometric structures refining the character varieties. In the case of one-cusped hyperbolic $3$-manifolds $M$ we generalize the QHI and get rational functions $\mathcal{H}_N^{h_f,h_c,k_c}$ depending on a finite set of cohomological data $(h_f,h_c,k_c)$ called {\it weights}. These functions are regular on a determined Abelian covering of degree $N^2$ of a Zariski open subset, canonically associated to $M$, of the geometric component of the variety of augmented $PSL(2,\mathbb{C})$-characters of $M$. New combinatorial ingredients are a weak version of branchings which exists on every triangulation, and state sums over weakly branched triangulations, including a sign correction which eventually fixes the sign ambiguity of the QHI. We describe in detail the invariants of three cusped manifolds, and present the results of numerical computations showing that the functions $\mathcal{H}_N^{h_f,h_c,k_c}$ depend on the weights as $N\rightarrow + \infty$, and recover the volume for some specific choices of the weights.

description: For international students, adjusting to the culture of their host country is an essential and challenging task, and previous research has inquired into factors that relate to better adjustment of such students. The current study investigates the possible role of intergroup ideology of polyculturalism in international students’ cultural adjustment, and the effect of cultural distance to this relationship in international students in the University of Macau using a quantitative cross-sectional survey approach. We surveyed 319 international students from different countries that varied in cultural distance from Macau and asked about their endorsement of polyculturalism and their current cultural adjustment. Results showed that who have the greater endorsement of polyculturalism adjusted to the host culture (Macau) better. Multiple regression analysis showed that who had greater endorsement of polyculturalism and came from lower cultural distance societies adjusted to the host culture (Macau) better. Moreover, cultural distance acted as a moderator between polyculturalism and cultural adjustment; specifically, the positive association between polyculturalism and cultural adjustment was observed only when the cultural distance was low. Implications and future directions for theory and practice are discussed.

description: The capability to probe the dispersion of elementary spin, charge, orbital, and lattice excitations has positioned resonant inelastic x-ray scattering (RIXS) at the forefront of photon science. Here we develop the scattering theory for RIXS on superconductors, calculating its momentum-dependent scattering amplitude. Considering superconductors with different pairing symmetries, we show that the low-energy scattering is strongly affected by the superconducting gap and coherence factors. This establishes RIXS as a tool to disentangle pairing symmetries and to probe the elementary excitations of unconventional superconductors.

description: We consider the Generalized Gibbs ensemble of the Ablowitz-Ladik lattice, and the Schur flow. We derive large deviations principles for the distribution of the empirical measures of the equilibrium measures for these ensembles. As a consequence, we deduce their almost sure convergence. Moreover, we are able to characterize their limit in terms of the equilibrium measure of the Circular, and the Jacobi beta ensemble respectively.

description: During drying of colloidal suspensions, colloidal particles can form concentrated particle layers beneath the receding free surface. The drying rate can gradually decrease with the growth of the particle layers. We construct a model to investigate how such drying characteristics is affected by interactions between particles. In this model, the formation of the particle layers is described by Langevin dynamics simulations, and the drying rate is evaluated from the permeation resistance of the particle layers. We show that the decrease in the drying rate is suppressed when the particles form aggregates by attractive interactions. The present model would enable us to predict and control the drying characteristics through the character of colloidal particles.
