Comparative analysis of criteria for filtering time series of word usage frequencies | This paper describes a method of nonlinear wavelet thresholding of time
series. The Ramachandran-Ranganathan runs test is used to assess the quality of
approximation. To minimize the objective function, it is proposed to use
genetic algorithms - one of the stochastic optimization methods. The suggested
method is test... | 0 | 0 | 0 | 1 | 0 | 0 |
Extend of the $\mathbb{Z}_2$-spin liquid phase on the Kagomé-lattice | The $\mathbb{Z}_2$ topological phase in the quantum dimer model on the
Kagomé-lattice is a candidate for the description of the low-energy physics
of the anti-ferromagnetic Heisenberg model on the same lattice. We study the
extend of the topological phase by interpolating between the exactly solvable

Accelerated Stochastic Quasi-Newton Optimization on Riemann Manifolds | We propose an L-BFGS optimization algorithm on Riemannian manifolds using
minibatched stochastic variance reduction techniques for fast convergence with

Bridging trees for posterior inference on Ancestral Recombination Graphs | We present a new Markov chain Monte Carlo algorithm, implemented in software
Arbores, for inferring the history of a sample of DNA sequences. Our principal

proceed independe... | 0 | 0 | 0 | 0 | 1 | 0 |
Strong magnetic frustration in Y$_{3}$Cu$_{9}$(OH)$_{19}$Cl$_{8}$: a distorted kagome antiferromagnet | We present the crystal structure and magnetic properties of
Y$_{3}$Cu$_{9}$(OH)$_{19}$Cl$_{8}$, a stoichiometric frustrated quantum spin
system with slightly distorted kagome layers. Single crystals of
Y$_{3}$Cu$_{9}$(OH)$_{19}$Cl$_{8}$ were grown under hydrothermal conditions.

The Character Field Theory and Homology of Character Varieties | We construct an extended oriented $(2+\epsilon)$-dimensional topological
field theory, the character field theory $X_G$ attached to a affine algebraic

Kapustin-Witten theory ($N... | 0 | 0 | 1 | 0 | 0 | 0 |
A new generator of chaotic bit sequences with mixed-mode inputs | This paper presents a new generator of chaotic bit sequences with mixed-mode

HAWC response to atmospheric electricity activity | The HAWC Gamma Ray observatory consists of 300 water Cherenkov detectors

Optical Music Recognition with Convolutional Sequence-to-Sequence Models | Optical Music Recognition (OMR) is an important technology within Music
Information Retrieval. Deep learning models show promising results on OMR

architecture call... | 1 | 0 | 0 | 0 | 0 | 0 |
Fractional Cable Model for Signal Conduction in Spiny Neuronal Dendrites | The cable model is widely used in several fields of science to describe the

Hedging in fractional Black-Scholes model with transaction costs | We consider conditional-mean hedging in a fractional Black-Scholes pricing
model in the presence of proportional transaction costs. We develop an explicit
formula for the conditional-mean hedging portfolio in terms of the recently
discovered explicit conditional law of the fractional Brownian motion.

Finite flat spaces | We say that a finite metric space $X$ can be embedded almost isometrically
into a class of metric spaces $C$, if for every $\epsilon > 0$ there exists an
embedding of $X$ into one of the elements of $C$ with the bi-Lipschitz
distortion less then $1 + \epsilon$. We show that almost isometric

On The Equivalence of Projections In Relative $α$-Entropy and Rényi Divergence | The aim of this work is to establish that two recently published projection
theorems, one dealing with a parametric generalization of relative entropy and

that the associated "Pyt... | 1 | 0 | 0 | 0 | 0 | 0 |
Comparing high dimensional partitions, with the Coclustering Adjusted Rand Index | The popular Adjusted Rand Index (ARI) is extended to the task of simultaneous

considered a... | 0 | 0 | 0 | 1 | 0 | 0 |
Dependence between Path-length and Size in Random Digital Trees | We study the size and the external path length of random tries and show that
they are asymptotically independent in the asymmetric case but strongly

random tries that t... | 0 | 0 | 1 | 0 | 0 | 0 |
Analysing Shortcomings of Statistical Parametric Speech Synthesis | Output from statistical parametric speech synthesis (SPSS) remains noticeably
