description: [transcription] Vous avez, monsieur et cher ami, l'art difficile et rare de vous concilier les coeurs, même ceux des grands.Monseigneur Durini qui vous a été voir à Nîmes d'après ce que je luiavais dit de vous, en est revenu pénétré des sentiments d'estime que vos avez su luiinspirer, et vous a publiquement comblé d'éloges. Il a eu la bonté de me savoir gré de vous avoir indiqué à lui, et depuis il m'a communiqué la réponse que vous luiavez faite.

Ce n'est pas seulement pour vous faire compliment là-dessus que j'ail'honneur de vous écrire aujourd'hui. Je viens vous consulter à mon ordinaire et pour la millième fois. J'insère dans cette lettre une pierre gravée qui me parait d'une haute antiquité, on y voit des lettres que je ne déchiffre pas, j'y entrevois les noms abrégés de Joannes et de Maria. Cependant j'en suis très incertain, je vous prie de vouloir bien l'examiner et de me dire votre sentiment là-dessus. Vous me ferez [fol. 179v] plaisir de me marquer de quel siècle cette pierre pourrait être et quelles sont vos conjectures à cet égard.

êtes-vous à Nîmes aussi dépourvu d'occasions d'acquérir que nous le sommes ici? Je ne trouve plus rien. Autrefois on me portait fréquemment des médailles aujourd'huij'en vois à peine une seule dans un an. Mes correspondances du Levant ne me fournissent que très peu de chose, les autres rien du tout. Je sens qu'il faudrait voyager et mes chaînes ne me permettent pas une absence d'un seul jour. Je suis cependant consolé de cette rareté d'acquisitions et des obstacles qui m'arrêtent si vous voulez bien me continuer votre amitié et comptez toujours sur l'attachement avec lequel je suis.

Monsieur

Votre très humble et très obéissant serviteur

description: We consider nonparametric estimation of L2, Renyi-α and Tsallis-α divergences between continuous distributions. Our approach is to construct estimators for particular integral functionals of two densities and translate them into divergence estimators. For the integral functionals, our estimators are based on corrections of a preliminary plug-in estimator. We show that these estimators achieve the parametric convergence rate of n−1/2 when the densities’ smoothness, s, are both at least d/4 where d is the dimension. We also derive minimax lower bounds for this problem which confirm that s>d/4 is necessary to achieve the n−1/2 rate of convergence. We validate our theoretical guarantees with a number of simulations.
Coulomb-Sturmian separable expansion approach: Three-body Faddeev calculations for Coulomb-like interactions

description: We demonstrate the feasibility and efficiency of the Coulomb-Sturmian separable expansion method for generating accurate solutions of the Faddeev equations. Results obtained with this method are reported for several benchmark cases of bosonic and fermionic three-body systems. Correct bound-state results in agreement with the ones established in the literature are achieved for short-range interactions. We outline the formalism for the treatment of three-body Coulomb systems and present a bound-state calculation for a three-boson system interacting via Coulomb plus short-range forces. The corresponding result is in good agreement with the answer from a recent stochastic-variational-method calculation.

description: The self-assembly of functionalized (patchy) particles with directional interactions into target structures is still a challenge, despite the significant experimental advances on their synthesis. The self-assembly pathways are typically characterized by high energy barriers that hinder the access to stable (equilibrium) structures. A possible strategy to tackle this challenge is to perform annealing cycles. By periodically switching on and off the inter-particle bonds, one expects to smooth-out the kinetic pathways and favor the assembly of targeted structures. Preliminary results have shown that the efficiency of annealing cycles depends strongly on their frequency. Here, we study numerically how this frequency-dependence scales with the strength of the directional interactions (size of the patch $σ$). We use analytical arguments to show that the scaling results from the statistics of a random walk in configurational space.

description: In this paper we propose new nonparametric estimators for a family of conditional mutual information and divergences. Our estimators are easy to compute; they only use simple k nearest neighbor based statistics. We prove that the proposed conditional information and divergence estimators are consistent under certain conditions, and demonstrate their consistency and applicability by numerical experiments on simulated and on real data as well.

description: When the Stratospheric Observatory for Infrared Astronomy (SOFIA) was conceived and its first science cases defined, exoplanets had not been detected. Later studies, however, showed that optical and near-infrared photometric and spectrophotometric follow-up observations during planetary transits and eclipses are feasible with SOFIA's instrumentation, in particular with the HIPO-FLITECAM and FPI+ optical and near infrared (NIR) instruments. Additionally, the airborne-based platform SOFIA has a number of unique advantages when compared to other ground- and space-based observatories in this field of research. Here we will outline these theoretical advantages, present some sample science cases and the results of two observations from SOFIA's first five observation cycles -- an observation of the Hot Jupiter HD 189733b with HIPO and an observation of the Super-Earth GJ 1214b with FLIPO and FPI+. Based on these early products available to this science case, we evaluate SOFIA's potential and future perspectives in the field of optical and infrared exoplanet spectrophotometry in the stratosphere.

description: We show that the Gauss-Bonnet correction to Einstein gravity induces a gravitational tachyon mode, namely an unstable spin 2 fluctuation, in the Randall-Sundrum I model. We demonstrate that this instability is generically related to the presence of a negative tension brane in the set-up, with or without $Z_2$-symmetry across it. Indeed it is shown that the tachyon mode is a bound state localised on any negative tension brane of co-dimension one, embedded in anti-de Sitter background. We discuss the possible resolution of this instability by the inclusion of induced gravity terms on the branes or by an effective four-dimensional cosmological constant.

Fluid-Structure Interaction with the Entropic Lattice Boltzmann Method

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We propose a novel fluid-structure interaction (FSI) scheme using the entropic multi-relaxation time lattice Boltzmann (KBC) model for the fluid domain in combination with a nonlinear finite element solver for the structural part. We show validity of the proposed scheme for various challenging set-ups by comparison to literature data. Beyond validation, we extend the KBC model to multiphase flows and couple it with FEM solver. Robustness and viability of the entropic multi-relaxation time model for complex FSI applications is shown by simulations of droplet impact on elastic superhydrophobic surfaces.
Nonparametric Divergence Estimators for Independent Subspace Analysis

Year: 2011
Subjects: subject: 170203 Knowledge Representation and Machine Learning
subject: FOS: Psychology

description: In this paper we propose new nonparametric Rényi, Tsallis, and L2 divergence estimators and demonstrate their applicability to mutual information estimation and independent subspace analysis. Given two independent and identically distributed samples, a naive divergence estimation approach would simply estimate the underlying densities, and plug these densities into the corresponding integral formulae. In contrast, our estimators avoid the need to consistently estimate these densities, and still they can lead to consistent estimations. Numerical experiments illustrate the efficiency of the algorithms.
Stabilization of nonlinear velocity profiles in athermal systems undergoing planar shear flow

description: We perform molecular dynamics simulations of model granular systems undergoing boundary-driven planar shear flow in two spatial dimensions with the goal of developing a more complete understanding of how dense particulate systems respond to applied shear. In particular, we are interested in determining when these systems will possess linear velocity profiles and when they will develop highly localized velocity profiles in response to shear. In previous work on similar systems we showed that nonlinear velocity profiles form when the speed of the shearing boundary exceeds the speed of shear waves in the material. However, we find that nonlinear velocity profiles in these systems are unstable at very long times. The degree of nonlinearity slowly decreases in time; the velocity profiles become linear when the granular temperature and density profiles are uniform across the system at long times. We measure the time $t_l$ required for the velocity profiles to become linear and find that $t_l$ increases as a power-law with the speed of the shearing boundary and increases rapidly as the packing fraction approaches random close packing. We also performed simulations in which differences in the granular temperature across the system were maintained by vertically vibrating one of the boundaries during shear flow. We find that nonlinear velocity profiles form and are stable at long times if the difference in the granular temperature across the system exceeds a threshold value that is comparable to the glass transition temperature in an equilibrium system at the same average density. Finally, the sheared and vibrated systems form stable shear bands, or highly localized velocity profiles, when the applied shear stress is lowered below the yield stress of the static part of the system.

description: Low-dimensional embedding, manifold learning, clustering, classification, and anomaly detection are among the most important problems in machine learning. Here we consider the setting where each instance of the inputs corresponds to a continuous probability distribution. These distributions are unknown to us, but we are given some i.i.d. samples from each of them. While most of the existing machine learning methods operate on points, i.e. finite-dimensional feature vectors, in our setting we study algorithms that operate on groups, i.e. sets of feature vectors. For this purpose, we propose new nonparametric, consistent estimators for a large family of divergences and describe how to apply them for machine learning problems. As important special cases, the estimators can be used to estimate R´enyi, Tsallis, Kullback-Leibler, Hellinger, Bhattacharyya distance, L2 divergences, and mutual information. We present empirical results on synthetic data, real word images, and astronomical data sets.

description: It is proved that any Rota---Baxter operator of zero weight on Jordan algebra of a nondegenerate bilinear symmetric form is nilpotent of index less or equal three. We state exact value of nilpotency index on simple Jordan algebra of Clifford type over fields $\mathbb{R}$, $\mathbb{C}$, and $\mathbb{Z}_p$. For $\mathbb{Z}_p$, we essentially use the results from number theory concerned quadratic residues and Chevalley---Warning theorem.

Nonparametric Decentralized Detection Based on Weighted Count Kernel

Publisher: name: Carnegie Mellon University
Year: 2012
Subjects: subject: 170203 Knowledge Representation and Machine Learning
subject: FOS: Psychology

description: The nonparametric decentralized detection problem is investigated, in which the joint distribution of the environmental event and the sensors' observations are not known and only a set of training samples are available. The system features rate constraints, i.e., integer bit constraints on sensors' transmissions, different qualities of observations, additional observations to the fusion center, and multi-level tree-structured network. Our study adopts the kernel-based nonparametric approach proposed by Nguyen, Wainwright, and Jordan with the following generalization. A weighted count kernel is introduced so that the corresponding reproducing kernel Hilbert space (RKHS) (over which the fusion center's decision rule is optimized) allows the fusion center's decision rule to count information from sensors and its own observations differently. In order to find the optimal decision rules, our optimization is solved by alternatively and recursively conducting three optimization steps: finding the optimal weight parameters in the weighted count kernel for selecting the best associated RKHS, finding the best optimal decision rule for the fusion center over the identified RKHS, and finding the local decision rules for sensors. Generalization to multilevel tree-structured networks is also discussed. Finally numerical results are provided to demonstrate the performance based on the proposed weighted count kernel.

description: Between 2004 and 2008, the UCL Institute of Archaeology Tavoliere-Gargano Prehistory Project conducted extensive surface finds and phenomenological landscape surveys across the Puglian (Apulian) Iron Age oppida of Arpi, Masseria Finizio, Ordona and Tiati. The aim was to characterise materially and phenomenologically, and to date, the settlement of these sites. These surveys focused on “randomly” selected survey stations, 69 at Arpi, 65 at Ordona and smaller numbers at the other two sites. These stations were field-walked and the superficial material culture within them identified and quantified. We also conducted a series of person-centred sensory experiments within and across grid squares. The rationale behind, and the preliminary results of, the person-centred sensory experiments were published in Hamilton and Whitehouse’s Phenomenology in Practice (2006), and a full account of some aspects of these surveys (which were conducted on a range of Puglian and other sites) in Hamilton and Whitehouse’s Neolithic Spaces, vol. 1 (2020). The results of the material culture surveys were long ago plotted and analysed, but were never interpreted and written up for publication. This interim summary, collated >10 years after the end of the project, is intended to make available to interested researchers some of the data generated, and, should this data be written up without full acknowledgement of the input of the present writer, establish his central role and long-term stake in the project as a whole. It is not interpretative and is not intended as a final word.
Noise-adaptive Margin-based Active Learning and Lower Bounds under Tsybakov Noise Condition

description: We present a polynomial-time noise-robust margin-based active learning algorithm to find homogeneous (passing the origin) linear separators and analyze its statistical rate of error convergence when labels are corrupted by noise. We show that when the imposed noise satisfies the Tsybakov low noise condition [MT+99, Tsy04] the algorithm is able to adapt to unknown level of noise and achieves optimal statistical rate up to polylogarithmic factors. In addition, the presented algorithm is simple and does not require prior knowledge of the amount of noise in the label distribution. We also derive lower bounds for margin based active learning algorithms under Tsybakov noise conditions (TNC) for the membership query synthesis scenario [Ang88]. Our result implies lower bounds for the stream based selective sampling scenario [Coh90] under TNC for some fairly simple data distributions. Quite surprisingly, we show that the sample complexity cannot be improved even if the underlying data distribution is as simple as the uniform distribution on the unit ball. Our proof involves the construction of a well-separated hypothesis set on the d-dimensional unit ball along with carefully designed label distributions for the Tsybakov noise condition. Our analysis might provide insights for other forms of lower bounds as well.

description: A new technique has been developed to remove the ionosphere's distorting effects from low frequency VLBI data. By fitting dispersive and non-dispersive components to the phases of multi-frequency data, the ionosphere can be effectively removed from the data without the use of {\em a priori} calibration information. This technique, along with the new gating capability of the VLBA correlator, was used to perform accurate astrometry on pulsar B0950+08, resulting in a much improved measurement of this pulsar's proper motion ($μ_α = -1.6 \pm 0.4$ mas/yr, $μ_δ = 29.5 \pm 0.5$ mas/yr) and parallax ($π= 3.6 \pm 0.3$ mas). This puts the pulsar at a distance of $280 \pm 25$ parsecs, about twice as far as previous estimates, but in good agreement with models of the electron density in the local bubble.

description: We work with $N-$dimensional compact real hyperbolic space $X_Γ$ with universal covering $M$ and fundamental group $Γ$. Therefore, $M$ is the symmetric space $G/K$, where $G=SO_1(N,1)$ and $K=SO(N)$ is a maximal compact subgroup of $G$. We regard $Γ$ as a discrete subgroup of $G$ acting isometrically on $M$, and we take $X_Γ$ to be the quotient space by that action: $X_Γ=Γ\backslash M = Γ\backslash G/K$. The natural Riemannian structure on $M$ (therefore on $X$) induced by the Killing form of $G$ gives rise to a connection $p-$form Laplacian ${\frak L}_p$ on the quotient vector bundle (associated with an irreducible representation of K). We study gauge theories based on abelian $p-$forms on the real compact hyperbolic manifold $X_Γ$. The spectral zeta function related to the operator ${\frak L}_p$, considering only the co-exact part of the $p-$forms and corresponding to the physical degrees of freedom, can be represented by the inverse Mellin transform of the heat kernel. The explicit thermodynamic fuctions related to skew-symmetric tensor fields are obtained by using the zeta-function regularization and the trace tensor kernel formula (which includes the identity and hyperbolic orbital integrals). Thermodynamic quantities in the high and low temperature expansions are calculated and new entropy/energy ratios established.

description: In the present contribution, a feedback control law is studied for a quasilinear parabolic equation. First, we prove the well-posedness and some regularity results for the Cauchy--Neumann problem for this equation, modified by adding an extra term which is a multiple of the subdifferential of the distance function from a closed convex set K of L2(Ω). Then, we consider convex sets of obstacle or double-obstacle type, and we can act on the factor of the feedback control in order to be able to reach the convex set within a finite time, by proving rigorously this property.

description: Although spectral clustering has enjoyed considerable empirical success in machine learning, its theoretical properties are not yet fully developed. We analyze the performance of a spectral algorithm for hierarchical clustering and show that on a class of hierarchically structured similarity matrices, this algorithm can tolerate noise that grows with the number of data points while still perfectly recovering the hierarchical clusters with high probability. We additionally improve upon previous results for k-way spectral clustering to derive conditions under which spectral clustering makes no mistakes. Further, using minimax analysis, we derive tight upper and lower bounds for the clustering problem and compare the performance of spectral clustering to these information theoretic limits. We also present experiments on simulated and real world data illustrating our results.

description: The self--energy of the strange baryon $Λ$ in $^{17}$O is calculated using a microscopic many--body approach which accounts for correlations beyond the mean--field or Hartree--Fock approximation. The non-locality and energy-dependence of the $Λ$ self--energy is discussed and the effects on the bound and scattering states are investigated. For the nucleon--hyperon interaction, we use the potential models of the Jülich and Nijmegen groups.

Recovering the flat-plane condition in electronic structure theory at semi-local DFT cost

description: The flat plane condition is the union of two exact constraints in electronic structure theory: i) energetic piecewise linearity with fractional electron removal or addition and ii) invariant energetics with change in electron spin in a half filled orbital. Semi-local density functional theory (DFT) fails to recover the flat plane, exhibiting convex fractional charge errors (FCE) and concave fractional spin errors (FSE) that are related to delocalization and static correlation errors. We previously showed that DFT+U eliminates FCE but now demonstrate that, like other widely employed corrections (i.e., Hartree Fock exchange), it worsens FSE. To find an alternative strategy, we examine the shape of semi-local DFT deviations from the exact flat plane, and we find this shape to be remarkably consistent across ions and molecules. We introduce the jmDFT approach, wherein corrections are constructed from few-parameter, low- order, functional forms that fit the shape of semi-local DFT errors. We select one such physically intuitive form and incorporate it self-consistently to correct semi-local DFT. We demonstrate on model systems that this jmDFT approach represents the first easy-to-implement, no-overhead approach to recovering the flat plane from semi-local DFT.

description: Экономика, насыщенная кризисными процессами, нестабильными прогнозами и другими диспропорциями, нуждается в углублении изучения теории экономического роста. Неустойчивость современной экономики позволяет утверждать, что диагностической силой обладают концепции, направленные на изучение взаимосвязей факторов развития, решение которых возможно с помощью разработки новых моделей, непосредственно основанных на использовании функций, отражающих циклический характер развития экономического роста.

description: The energy extinction cross section of a concentrically layered sphere varies with velocity as the Doppler shift moves the spectral content of the incident signal in the sphere's co-moving inertial reference frame toward or away from resonances of the sphere. Computations for hollow gold nanospheres show that the energy extinction cross section is high when the Doppler shift moves the incident signal's spectral content in the co-moving frame near the wavelength of the sphere's localized surface plasmon resonance. The energy extinction cross section of a three-layer sphere consisting of an olivine-silicate core surrounded by a porous and a magnetite layer, which is used to explain extinction caused by interstellar dust, also depends strongly on velocity. For this sphere, computations show that the energy extinction cross section is high when the Doppler shift moves the spectral content of the incident signal near either of olivine-silicate's two localized surface phonon resonances at 9.7 $μ$m and 18 $μ$m.

description: Within the framework of Classical Molecular Dynamics, we study the collision Au + Au at an incident energy of 35 MeV/nucleon. It is found that the system shows a critical behaviour at peripheral impact parameters, revealed through the analysis of conditional moments of charge distributions, Campi Scatter Plot, and the occurrence of large fluctuations in the region of the Campi plot where this critical behaviour is expected. When applying the experimental filters of the MULTICS-MINIBALL apparatus, it is found that criticality signals can be hidden due to the inefficiency of the experimental apparatus. The signals are then recovered by identifying semi-peripheral and peripheral collisions looking to the velocity distribution of the largest fragment, then by selecting the most complete events.

description: Modeling networks is an active area of research and is used for many applications ranging from bioinformatics to social network analysis. An important operation that is often performed in the course of graph analysis is node clustering. Popular methods for node clustering such as the normalized cut method have their roots in graph partition optimization and spectral graph theory. Recently, there has been increasing interest in modeling graphs probabilistically using stochastic block models and other approaches that extend it. In this paper, we present an empirical study that compares the node clustering performances of state-of-the-art algorithms from both the probabilistic and spectral families on undirected graphs. Our experiments show that no family dominates over the other and that network characteristics play a significant role in determining the best model to use.

description: Horowitz and Maldacena have suggested that the unitarity of the black hole S-matrix can be reconciled with Hawking's semiclassical arguments if a final-state boundary condition is imposed at the spacelike singularity inside the black hole. We point out that, in this scenario, departures from unitarity can arise due to interactions between the collapsing body and the infalling Hawking radiation inside the event horizon. The amount of information lost when a black hole evaporates depends on the extent to which these interactions are entangling.

Mixing properties of growing networks and the Simpson's paradox

description: We analyze the mixing properties of growing networks and find that, in some cases, the assortativity patterns are reversed once links' direction is considered: the disassortative behavior observed in such networks is a spurious effect, and a careful analysis reveals genuine positive correlations. We prove our claim by analytical calculations and numerical simulations for two classes of models based on preferential attachment and fitness. Such counterintuitive phenomenon is a manifestation of the well known Simpson's paradox. Results concerning mixing patterns may have important consequences, since they reflect on structural properties as resilience, epidemic spreading and synchronization. Our findings suggest that a more detailed analysis of real directed networks, such as the World Wide Web, is needed.
