description: We present new algorithms for the k-means clustering problem. They use the kd-tree data structure to reduce the large number of nearest-neighbor queries issued by the traditional algorithm. Sufficient statistics are stored in the nodes of the kd-tree. Then, an analysis of the geometry of the current cluster centers results in great reduction of the work needed to update the centers. Our algorithms behave exactly as the traditional k-means algorithm. Proofs of correctness are included. The kd-tree can also be used to initialize the k-means starting centers efficiently. Our algorithms can be easily extended to provide fast ways of computing the error of a given cluster assignment, regardless of the method in which those clusters were obtained. We also show how to use them in a setting which allows approximate clustering results, with the benefit of running faster. We have implemented and tested our algorithms on both real and simulated data. Results show a speedup factor of up to 170 on real astrophysical data, and superiority over the naive algorithm on simulated data in up to 5 dimensions. Our algorithms scale well with respect to the number of points and number of centers, allowing for clustering with tens of thousands of centers.

description: Two-loop electroweak corrections to the electron, muon, and tau lepton anomalous magnetic moments have been computed recently. Effects of hadronic contributions to the photon propagator in two-loop QED corrections have also been reanalysed. The common technique used in both calculations was asymptotic expansion of Feynman diagrams in the ratio of lepton mass to some heavy mass scale. In this talk we present some details of this method paying particular attention to the expansion of multi-scale diagrams.

description: Настоящая статья является продолжением исследования, посвященного антиминсам, содержащим документальные записи, как особого вида историческим источникам. В работе приводятся результаты исследования антиминса Николаевской церкви села Армавир, на полях которого имеется запись о том, что его использование «благословляется и для походного священнодейства в храме и на всяком святом месте». В настоящее время описываемый антиминс является одной из немногих реликвий Свято-Никольского кафедрального собора, свидетельствующих о прошлом в религиозной жизни города. Появление данной записи связано с историческими событиями 1914 г. в Армавире. На основании анализа ряда архивных документов по истории Николаевской церкви 1914–1915 гг. автор пришел к выводу, что преобразование статуса Армавира из села в город повлекло некоторые изменения и в церковной жизни. Вероятно, духовенство храма получило новый антиминс с указанием нового положения населенного пункта (город), в то время как прежний антиминс после 12 апреля 1915 г. стал использоваться в военных нуждах.

description: The powerful discovery capabilities available in the ADS bibliographic services are possible thanks to the design of a flexible search and retrieval system based on a relational database model. Bibliographic records are stored as a corpus of structured documents containing fielded data and metadata, while discipline-specific knowledge is segregated in a set of files independent of the bibliographic data itself. The creation and management of links to both internal and external resources associated with each bibliography in the database is made possible by representing them as a set of document properties and their attributes. To improve global access to the ADS data holdings, a number of mirror sites have been created by cloning the database contents and software on a variety of hardware and software platforms. The procedures used to create and manage the database and its mirrors have been written as a set of scripts that can be run in either an interactive or unsupervised fashion. The ADS can be accessed at http://adswww.harvard.edu

Phenomenological local potentials for π^- + ^{12}C scattering from 120 to 766 MeV

description: Pion-nucleus scattering cross sections are calculated by solving a Schrödinger equation reduced from the Klein-Gordon equation. Local potentials are assumed, and phenomenological potential parameters are searched energy-dependently for $π^{-} + ^{12}$C system so as to reproduce not only elastic differential cross sections but also total elastic, reaction and total cross sections at 13 pion incident energies from 120 to 766 MeV. The real and imaginary parts of the local potentials thus obtained are shown to satisfy the dispersion relation. The imaginary part of the potentials as a function of the pion energy is found to peak near the $Δ$(1232)-resonance energy. The strong absorption radius of the pion projectile with incident energies near the $Δ$-resonance region is found to be about $1.6 A^{1/3}$ fm, which is consistent with previous studies of the region where the decay of the $Δ$'s takes place in nuclei. The phenomenological local potentials are then compared with the local potentials exactly phase-shift equivalent to Kisslinger potentials for pion energies near the $Δ$-resonance.

description: Iteration is often sufficient for a simple hand to accomplish complex tasks, at the cost of an increase in the expected time to completion. In this paper, we minimize that overhead time by allowing a simple hand to abort early and retry as soon as it realizes that the task is likely to fail. We present two key contributions. First, we learn a probabilistic model of the relationship between the likelihood of success of a grasp and its grasp signature--the trace of the state of the hand along the entire grasp motion. Second, we model the iterative process of early abort and retry as a Markov chain and optimize the expected time to completion of the grasping task by effectively thresholding the likelihood of success. Experiments with our simple hand prototype tasked with grasping and singulating parts from a bin show that early abort and retry significantly increases efficiency.

description: We study the fine scale $L^2$-mass distribution of toral Laplace eigenfunctions with respect to random position, in 2 and 3 dimensions. In 2d, under certain flatness assumptions on the Fourier coefficients and generic restrictions on energy levels, both the asymptotic shape of the variance is determined and the limiting Gaussian law is established, in the optimal Planck-scale regime. In 3d the asymptotic behaviour of the variance is analysed in a more restrictive scenario ("Bourgain's eigenfunctions"). Other than the said precise results, lower and upper bounds are proved for the variance, under more general flatness assumptions on the Fourier coefficients.

description: Previously, it was noticed that in some space-times with Killing horizons some curvature components, responsible for tidal forces, small or even zero in the static frame, become enhanced from the viewpoint of a falling observer. This leads to the notion of so-called naked black holes. If some components in the frame attached to a free-falling observer formally diverge, although scalar invariants remain finite, such space-times was named "truly naked black holes" (in mathematical language, one can speak about non-scalar singularity). Previous results included static spherically symmetric or distorted static metrics. In the present work, we generalized them to include rotation in consideration. We also scrutiny how the algebraic type can change in the vicinity of the horizon due to local Lorentz boost. Our approach essentially uses the Newman-Penrose formalism, so we analyze the behavior of Weyl scalar for different kinds of observers.

Представляя собой хорошо укреплённые городские архиерейские кварталы, эти замковые комплексы, к сожалению, остаются малоизученным феноменом древнерусской жизни. В рамках представленной статьи предпринята попытка сформулировать ряд ключевых проблем, касающихся жизни святительского двора. Основное внимание уделено систематизации некоторых архитектурных особенностей организации подобных замков. При этом основное внимание обращено на установление связи между епископскими замками и княжескими замками-резиденциями. Представленные в работе наблюдения имеют предварительный характер и направлены на поиск новых перспектив в изучении архиерейского управления домонгольской Руси.

description: Церковь в Древней Руси настолько мало нуждалась в рецепции византийского церковного права, что немногочисленные опыты в области кодификации права привели лишь к созданию правовых сборников с включением в них фрагментов или полных сводов канонических предписаний. При этом в самой Древней Руси церковное правотворчество было развито чрезвычайно слабо. Некоторые созданные на Руси в ХI–ХII веках тексты стали пониматься как правовые в более поздние эпохи. Традиционно считается, что запрет на общение с католиками носит канонический характер. Подробный анализ формирования церковного права в Киевской Руси позволяет заключить, что, по крайней мере, до появления Сербской Кормчей 1262 года антилатинские запреты не регламентировались церковным правом. В княжеских гражданских и церковных правовых памятниках тема отношения к латинству не затрагивалась. Лишь по мере того, как архиерейские (митрополитов Георгия и Иоанна и епископа Нифонта) ответы на вопрошания клириков приобретали канонический статус, т. е. не ранее конца ХIII века, правовой статус стал постепенно распространяться и на иные памятники антилатинской полемической литературы, доступной на тот момент на Руси.
Thermal Instability and the Formation of Clumpy Gas Clouds

Year: 2000

description: The radiative cooling of optically thin gaseous regions and the formation of a two-phase medium and of cold gas clouds with a clumpy substructure is investigated. In optically thin clouds, the growth rate of small isobaric density perturbations is independent of their length scale. However, the growth of a perturbation is limited by its transition from isobaric to isochoric cooling. The temperature at which this transition occurs decreases with the length scale of the perturbation. Consequently small scale perturbations have the potential to reach higher amplitudes than large scale perturbations. When the amplitude becomes nonlinear, advection overtakes the pressure gradient in promoting the compression resulting in an accelerated growth of the disturbance. The critical temperature for transition depends on the initial amplitude. The fluctuations which can first reach nonlinearity before their isobaric to isochoric transition will determine the characteristic size and mass of the cold dense clumps which would emerge from the cooling of an initially nearly homogeneous region of gas. Thermal conduction is in general very efficient in erasing isobaric, small-scale fluctuations, suppressing a cooling instability. A weak, tangled magnetic field can however reduce the conductive heat flux enough for low-amplitude fluctuations to grow isobarically and become non-linear if their length scales are of order 0.01 pc. Finally, we demonstrate how a 2-phase medium, with cold clumps being pressure confined in a diffuse hot residual background component, would be sustained if there is adequate heating to compensate the energy loss.

В историографии господствует точка зрения, согласно которой княжеские прозвища сочинялись в быту, указывая на свойства характера, доблести, те или иные физические особенности их носителей. «Бытовую» версию сложно, однако, признать универсальной. Некоторые княжеские прозвища имеют книжные параллели и, скорее всего, являются заимствованными из литературы, составлявшей круг чтения древнерусских летописцев.
Brout-Englert-Higgs physics: From foundations to phenomenology

description: The aim of this review is to describe the field-theoretical foundations of Brout-Englert-Higgs (BEH) physics, and to show how the usual phenomenology arises from it. This requires to give a precise and gauge-invariant meaning to the underlying physics. This is complicated by the fact that concepts like the Higgs vacuum expectation value or the separation between confinement and the BEH effect loose their meaning beyond perturbation theory. This is addressed by carefully constructing the corresponding theory space and the quantum phase diagram. The physical spectrum needs then to be also given in terms of gauge-invariant, i. e. composite, states. Using gauge-invariant perturbation theory, as developed by Froehlich, Morchio, and Strocchi, it is possible to rederive conventional perturbation theory. This derivation explicitly shows why the description of the standard model in terms of the unphysical, gauge-dependent, elementary states of the Higgs and W-bosons and Z-boson, but also of the elementary fermions, is adequate and successful. These are unavoidable consequences of the field theory underlying the standard model, from which the usual picture emerges. The validity of this emergence can only be tested non-perturbatively. Such tests, in particular using lattice gauge theory, will be reviewed as well. They fully confirm the underlying mechanisms. It will be seen that the structure of the standard model is very special, and qualitative changes occur beyond it. The extension beyond the standard model will therefore also be reviewed. Particular attention will be given to structural differences arising for phenomenology. Again, non-perturbative tests of these results will be reviewed. Finally, to make this review self-contained a brief discussion of issues like the triviality and hierarchy problem, and how they fit into a fundamental field-theoretical formulation, is included.

description: A gripper is described for manipulation in natural, unstructured environments. The specific manipulation task is to pick up surface material such as pebbles or small rocks in a natural terrain. The application is to give autonomous sampling capabilities to an autonomous vehicle for planetary exploration. The authors describe the task analysis process that led to the selection of a configuration with three soft fingers. They carry out a complete analysis of the stability of a grasp for this gripper including an analysis of the deformation of the fingers at the points of contact. The implementation of a grasp selection algorithm is described, and results on three-dimensional representations of objects computed from range data are presented

description: «Задонщина» — выдающийся памятник древнерусской литературы, посвященный Куликовской битве 1380 г. Сопоставление шести сохранившихся списков памятника позволяет восстановить логику сюжетной линии начала произведения. Важное место в тексте занимает мотив Божественного возмездия за нарушение границ Руси татарами. Эти сакральные границы были установлены, по мнению автора «Задонщины», после Потопа, в ходе раздела земель сыновьями Ноя. Три его сына — Сим, Хам и Иафет, поклялись за своих потомков, что те никогда не будут нарушать установленных границ. Однако в 1223 г. потомки Сима, татары, вторглись в пределы земель потомков Иафета — русских. Основная смысловая нагрузка вступления «Задонщины» была связана с раскрытием этого сюжета. Обращением к метафоричным поэтическим образам автор «Задонщины» показал неизбежность наступления в свой срок Божественного возмездия, что и случилось в 1380 г. Русские князья, как потомки Иафета, выступали орудием Божественного возмездия татарам за нарушение сакральных границ.

Alternation, Sparsity and Sensitivity : Bounds and Exponential Gaps

description: $\newcommand{\sp}{\mathsf{sparsity}}\newcommand{\s}{\mathsf{s}}\newcommand{\al}{\mathsf{alt}}$ The well-known Sensitivity Conjecture states that for any Boolean function $f$, block sensitivity of $f$ is at most polynomial in sensitivity of $f$ (denoted by $\s(f)$). The XOR Log-Rank Conjecture states that for any $n$ bit Boolean function, $f$ the communication complexity of a related function $f^{\oplus}$ on $2n$ bits, (defined as $f^{\oplus}(x,y)=f(x\oplus y)$) is at most polynomial in logarithm of the sparsity of $f$ (denoted by $\sp(f)$). A recent result of Lin and Zhang (2017) implies that to confirm the above conjectures it suffices to upper bound alternation of $f$ (denoted $\al(f)$) for all Boolean functions $f$ by polynomial in $\s(f)$ and logarithm of $\sp(f)$, respectively. In this context, we show the following : * There exists a family of Boolean functions for which $\al(f)$ is at least exponential in $\s(f)$ and $\al(f)$ is at least exponential in $\log \sp(f)$. En route to the proof, we also show an exponential gap between $\al(f)$ and the decision tree complexity of $f$, which might be of independent interest. * As our main result, we show that, despite the above gap between $\al(f)$ and $\log \sp(f)$, the XOR Log-Rank Conjecture is true for functions with the alternation upper bounded by $poly(\log n)$. It is easy to observe that the Sensitivity Conjecture is also true for this class of functions. * The starting point for the above result is the observation (derived from Lin and Zhang (2017)) that for any Boolean function $f$ and $m \ge 2$, $deg(f)\le \al(f)deg_2(f)deg_m(f)$ where $deg(f)$, $deg_2(f)$ and $deg_m(f)$ are the degrees of $f$ over $\mathbb{R}$, $\mathbb{F}_2$ and $\mathbb{Z}_m$ respectively. We also show three further applications of this observation.

description: We present non-adiabatic hydrodynamic simulations of a supersonic light jet propagating into a fully ionized medium of uniform density on a scale representative of the narrow line region (NLR) in Seyfert galaxies with associated radio jets. In this regime the cooling distance of the swept up gas in the bowshock of the jet is of the same order as the transverse extent of the jet bowshock, as opposed to the more extreme regimes found for more powerful adiabatic large scale jets or the slow galactic jets which have been simulated previously. We calculate the emissivity for the H_alpha line and radio synchrotron emission. We find that the structure of the line emitting cold envelope of the jet cocoon is strongly dependent on the non-stationary dynamics of the jet head as it propagates through the ambient medium. We observe the formation of cloud-like high density regions which we associate with NLR clouds and filaments. We find that some of these clouds might be partially neutral and represent sites of jet induced star formation. The calculated H_alpha flux and the spectral line width are consistent with NLR observations. The simulation of the radio-optical emission with radiative cooling confirms the basic result of the geometric bowshock model developed by Taylor et al. (1989) that the start of noticeable optical line emission can be significantly offset from the hotspot of the radio emission. However, the time-dependent nature of the jet dynamics implies significant differences from their geometric bowshock model.

description: We present a perception system, called Artisan, that semi-automatically builds 3-D models of a robot’s workspace. Range images are acquired with a scanning laser rangefinder and then processed, based on a systematic sensor characterization, to remove noise and artifacts. Complex 3-D objects represented as surface meshes are subsequently recognized in the range images and inserted into a virtual workspace. This graphical virtual workspace is then used to by human operators to plan and execute remote robotic operations.

description: В наше время очевидна сильная геополитическая напряженность в некоторых православных странах. Радикальные националисты предпринимают попытки переписать историю и навязать разные культуры людям, которые никогда не были частью этих культур. В этой короткой статье описывается, какое историческое место и какое отношение имеют польские земли и их народ к глубокому духовному и культурному наследию Святой Руси. Можно ли утверждать, что эти земли или их части находились под влиянием сначала Киевской, а затем и Московской Руси, прежде чем она оказалась под влиянием римского папы? Если это так, в какой степени это влияние было Руси? И, наконец, какая часть наследия Святой Руси должна быть связана с православными верующими в Польше, исторически и сегодня. Цель этой работы в том, чтобы попытаться ответить, в какой степени православие в Польше может быть связано со Святой Русью и ее наследием.

description: Статья посвящена анализу литературоведческого аспекта репрезентации образа Витовта Великого в позднесредневековой хронографии. Образ Витовта изучен на основании летописей и хроник Великого княжества Литовского, опубликованных в 32 и 35 томах «Полного собрания русских летописей». Делается вывод, что в источниках раскрыта цельная личность Витовта как последовательного и методичного государственного стратега, смелого воина, умного и проницательного политика. Именно Великий Витовт лучше всех сумел воспользоваться предоставленными историей возможностями и открыл миру Литву как могучее государство. Образ Витовта сопоставлен с образом великого князя Дмитрия Донского, прославленного в лике святых, и во многом схожего с Витовтом.
A Study of Reinforcement Learning in the Continuous Case by the Means of Viscosity Solutions

description: This paper proposes a study of Reinforcement Learning (RL) for continuous state-space and time control problems, based on the theoretical framework of viscosity solutions (VSs). We use the method of dynamic programming (DP) which introduces the value function (VF), expectation of the best future cumulative reinforcement. In the continuous case, the value function satisfies a non-linear first (or second) order (depending on the deterministic or stochastic aspect of the process) differential equation called the Hamilton-Jacobi-Bellman (HJB) equation. It is well known that there exists an infinity of generalized solutions (differentiable almost everywhere) to this equation, other than the VF. We show that gradient-descent methods may converge to one of these generalized solutions, thus failing to find the optimal control. In order to solve the HJB equation, we use the powerful framework of viscosity solutions and state that there exists a unique viscosity solution to the HJB equation, which is the value function. Then, we use another main result of VSs (their stability when passing to the limit) to prove the convergence of numerical approximations schemes based on finite difference (FD) and finite element (FE) methods. These methods discretize, at some resolution, the HJB equation into a DP equation of a Markov Decision Process (MDP), which can be solved by DP methods (thanks to a "strong" contraction property) if all the initial data (the state dynamics and the reinforcement function) were perfectly known. However, in the RL approach, as we consider a system in interaction with some a priori (at least partially) unknown environment, which learns "from experience" the initial data are not perfectly known but have to be approximated during learning. The main contribution of this work is to derive a general convergence theorem for RL algorithms when one uses only "approximations" (in a sense of satisfying some "weak" contraction property) of the initial data. This result can be used for model-based or model-free RL algorithms, with off-line or on-line updating methods, for deterministic or stochastic state dynamics (though this latter case is not described here), and based on FE or FD discretization methods. It is illustrated with several RL algorithms and one numerical simulation for the "Car on the Hill" problem.
A Spherical Representation for Recognition of Free-Form Surfaces

description: Introduces a new surface representation for recognizing curved objects. The authors approach begins by representing an object by a discrete mesh of points built from range data or from a geometric model of the object. The mesh is computed from the data by deforming a standard shaped mesh, for example, an ellipsoid, until it fits the surface of the object. The authors define local regularity constraints that the mesh must satisfy. The authors then define a canonical mapping between the mesh describing the object and a standard spherical mesh. A surface curvature index that is pose-invariant is stored at every node of the mesh. The authors use this object representation for recognition by comparing the spherical model of a reference object with the model extracted from a new observed scene. The authors show how the similarity between reference model and observed data can be evaluated and they show how the pose of the reference object in the observed scene can be easily computed using this representation. The authors present results on real range images which show that this approach to modelling and recognizing 3D objects has three main advantages: (1) it is applicable to complex curved surfaces that cannot be handled by conventional techniques; (2) it reduces the recognition problem to the computation of similarity between spherical distributions; in particular, the recognition algorithm does not require any combinatorial search; and (3) even though it is based on a spherical mapping, the approach can handle occlusions and partial views
High-dimensional single-index Bayesian modeling of brain atrophy

description: We propose a model of brain atrophy as a function of high-dimensional genetic information and low dimensional covariates such as gender, age, APOE gene, and disease status. A nonparametric single-index Bayesian model of high dimension is proposed to model the relationship with B-spline series prior on the unknown functions and Dirichlet process scale mixture of centered normal prior on the distributions of the random effects. The posterior rate of contraction without the random effect is established for a fixed number of regions and time points with increasing sample size. We implement an efficient computation algorithm through a Hamiltonian Monte Carlo (HMC) algorithm. The performance of the proposed Bayesian method is compared with the corresponding least square estimator in the linear model with horseshoe prior, LASSO and SCAD penalization on the high-dimensional covariates. The proposed Bayesian method is applied to a dataset on volumes of brain regions recorded over multiple visits of 748 individuals using 620,901 SNPs and 6 other covariates for each individual, to identify factors associated with brain atrophy.

description: The ISO-SWS 2.5-45 um infrared spectroscopic observations of the nucleus of the Seyfert 2 galaxy NGC 1068 (see companion paper) are combined with a compilation of UV to IR narrow emission line data to determine the spectral energy distribution (SED) of the obscured extreme-UV continuum that photoionizes the narrow line emitting gas in the active galactic nucleus. We search a large grid of gas cloud models and SEDs for the combination that best reproduces the observed line fluxes and NLR geometry. Our best fit model reproduces the observed line fluxes to better than a factor of 2 on average and is in general agreement with the observed NLR geometry. It has two gas components that are consistent with a clumpy distribution of dense outflowing gas in the center and a more extended distribution of less dense and more clumpy gas farther out that has no net outflow. The best fit SED has a deep trough at ~4 Ryd, which is consistent with an intrinsic Big Blue Bump that is partially absorbed by ~6x10^19 cm^-2 of neutral hydrogen interior to the NLR.

description: We measure the conductivity of neutral fermions in a cubic optical lattice. Using in-situ fluorescence microscopy, we observe the alternating current resultant from a single-frequency uniform force applied by displacement of a weak harmonic trapping potential. In the linear response regime, a neutral-particle analogue of Ohm's law gives the conductivity as the ratio of total current to force. For various lattice depths, temperatures, interaction strengths, and fillings, we measure both real and imaginary conductivity, up to a frequency sufficient to capture the transport dynamics within the lowest band. The spectral width of the real conductivity reveals the current dissipation rate in the lattice, and the integrated spectral weight is related to thermodynamic properties of the system through a sum rule. The global conductivity decreases with increased band-averaged effective mass, which at high temperatures approaches a T-linear regime. Relaxation of current is observed to require a finite lattice depth, which breaks Galilean invariance and enables damping through collisions between fermions.
