Online Computation of Abelian Runs
2015
Given a word $w$ and a Parikh vector $\mathcal{P}$, an abelian run of period $\mathcal{P}$ in $w$ is a maximal occurrence of a substring of $w$ having abelian period $\mathcal{P}$. We give an algorithm that finds all the abelian runs of period $\mathcal{P}$ in a word of length $n$ in time $O(n\times |\mathcal{P}|)$ and space $O(\sigma+|\mathcal{P}|)$.
Fast computation of abelian runs
2016
Given a word $w$ and a Parikh vector $\mathcal{P}$, an abelian run of period $\mathcal{P}$ in $w$ is a maximal occurrence of a substring of $w$ having abelian period $\mathcal{P}$. Our main result is an online algorithm that, given a word $w$ of length $n$ over an alphabet of cardinality $\sigma$ and a Parikh vector $\mathcal{P}$, returns all the abelian runs of period $\mathcal{P}$ in $w$ in time $O(n)$ and space $O(\sigma+p)$, where $p$ is the norm of $\mathcal{P}$, i.e., the sum of its components. We also present an online algorithm that computes all the abelian runs with periods of norm $p$ in $w$ in time $O(np)$, for any given norm $p$. Finally, we give an $O(n^2)$-time offline randomi…
Symbolic integration of hyperexponential 1-forms
2019
Let $H$ be a hyperexponential function in $n$ variables $x=(x_1,\dots,x_n)$ with coefficients in a field $\mathbb{K}$, $[\mathbb{K}:\mathbb{Q}] <\infty$, and $\omega$ a rational differential $1$-form. Assume that $H\omega$ is closed and $H$ transcendental. We prove using Schanuel conjecture that there exist a univariate function $f$ and multivariate rational functions $F,R$ such that $\int H\omega= f(F(x))+H(x)R(x)$. We present an algorithm to compute this decomposition. This allows us to present an algorithm to construct a basis of the cohomology of differential $1$-forms with coefficients in $H\mathbb{K}[x,1/(SD)]$ for a given $H$, $D$ being the denominator of $dH/H$ and $S\in\mathbb{K}[x…
Mahonian STAT on words
2016
In 2000, Babson and Steingrimsson introduced the notion of what is now known as a permutation vincular pattern, and based on it they re-defined known Mahonian statistics and introduced new ones, proving or conjecturing their Mahonity. These conjectures were proved by Foata and Zeilberger in 2001, and by Foata and Randrianarivony in 2006.In 2010, Burstein refined some of these results by giving a bijection between permutations with a fixed value for the major index and those with the same value for STAT , where STAT is one of the statistics defined and proved to be Mahonian in the 2000 Babson and Steingrimsson's paper. Several other statistics are preserved as well by Burstein's bijection.At…
Estimating with kernel smoothers the mean of functional data in a finite population setting. A note on variance estimation in presence of partially o…
2014
In the near future, millions of load curves measuring the electricity consumption of French households in small time grids (probably half hours) will be available. All these collected load curves represent a huge amount of information which could be exploited using survey sampling techniques. In particular, the total consumption of a specific cus- tomer group (for example all the customers of an electricity supplier) could be estimated using unequal probability random sampling methods. Unfortunately, data collection may undergo technical problems resulting in missing values. In this paper we study a new estimation method for the mean curve in the presence of missing values which consists in…
A bridge over troubled water? Celebrities in journalism connecting implicit and institutional politics
2013
This article looks empirically into how audience members evaluate celebrities in journalism; whether and how celebrities help them to envisage their relationship to politics and media and consequently regard themselves as citizens. The analysis generates a broad and audience-based understanding of celebrities in nine focus group discussions, wherein more than 50 citizens in Finland discussed their favourite celebrities. The discussions revealed three interpretative frames explaining what the celebrities represent to the participants: normative, critical and alternative. In the first two, the groups impose a critical view on celebrities, whereas only the latter one comes close to the optimi…
Principles of Calculation of Track Access Charges in Rail Freight Transport in Poland
2019
Non-discriminatory rules for access to the railway infrastructure as well as transparent pricing system are the essential factors of ensuring that the freight transport in Poland is competitive enough. Infrastructure managers pass some categories of their costs (e.g. for maintaining of railway infrastructure) on railway undertakings in the form of access charges verified andaccepted by the Polish regulatory body. In general, approximately one – third of their costs shall be paid by railway undertakings. Given that access charges are treated as one of the most important factors for both railway undertakings and railway infrastructure man-agers. The aim of this article is to review the main p…
OS ECJ-TF 2/2016 on the Decision of the Court of Justice of the European Union of 13 July 2016 in Brisal and KBC Finance Ireland (Case C-18/15), on t…
2016
This article examines the decision of the CJEU in Brisal and KBC Finance Ireland (Case C-18/15) of 13 July 2016. Following a Portuguese reference for a preliminary ruling, the Court's decision provides further clarification on the permissibility of withholding taxation within the European Union. In relation to interest, the Court held that non-resident taxpayers may be subject to withholding taxes (even if comparable residents pursuing the same activity are not) but that non-residents may nevertheless not be taxed on gross income (when comparable residents are taxed on net profits) and are, therefore, entitled to deduct expenses directly connected to their business activity.
Linear Response Theory with finite-range interactions
2021
International audience; This review focuses on the calculation of infinite nuclear matter response functions using phenomenological finite-range interactions, equipped or not with tensor terms. These include Gogny and Nakada families, which are commonly used in the literature. Because of the finite-range, the main technical difficulty stems from the exchange terms of the particle–hole interaction. We first present results based on the so-called Landau and Landau-like approximations of the particle–hole interaction. Then, we review two methods which in principle provide numerically exact response functions. The first one is based on a multipolar expansion of both the particle–hole interactio…
The Discursive Constitution of a World-Spanning Region and the Role of Empty Signifiers: The Case of Francophonia
2007
The cultural turn in political science, history, and political geography has opened new perspectives on the division of the world into geographic entities. Nation-states, regions, districts, etc., are no longer qualified as quasi-natural objects based upon intrinsic qualities but, rather, as contingent results of social or accordingly discursive processes. The Organisation Internationale de la Francophonie (OIF) defines Francophonia as an “geocultural space” (espace geoculturel) and an international community of more than 50 states. In this contribution, the concept of political communities as “imagined communities” and the advancements of discourse theory by Laclau and Mouffe are used in o…
