Christoffel words and the Calkin-Wilf tree
No full textIn this note we present some results on the Calkin-Wilf tree of irreducible fractions, giving an insight on the duality relating it to the Stern-Brocot tree, and proving noncommutative versions of known results relating labels of the Calkin-Wilf trees to hyperbinary expansions of positive integers. The main tool is the Christoffel tree introduced in a paper by Berstel and de Luca
A new characteristic property of rich words
No full textOriginally introduced and studied by the third and fourth authors together with J. Justin and S. Widmer (2008), rich words constitute a new class of finite and infinite words characterized by containing the maximal number of distinct palindromes. Several characterizations of rich words have already been established. A particularly nice characteristic property is that all 'complete returns' to palindromes are palindromes. In this note, we prove that rich words are also characterized by the property that each factor is uniquely determined by its longest palindromic prefix and its longest palindromic suffix
Rich, Sturmian, and trapezoidal words
No full textIn this paper we explore various interconnections between rich words, Sturmian words, and trapezoidal words. Rich words, first introduced by the second and third authors together with J. Justin and S. Widmer, constitute a new class of finite and infinite words characterized by having the maximal number of palindromic factors. Every finite Sturmian word is rich, but not conversely. Trapezoidal words were first introduced by the first author in studying the behavior of the subword complexity of finite Sturmian words. Unfortunately this property does not characterize finite Sturmian words. In this note we show that the only trapezoidal palindromes are Sturmian. More generally we show that Sturmian palindromes can be characterized either in terms of their subword complexity (the trapezoidal property) or in terms of their palindromic complexity. We also obtain a similar characterization of rich palindromes in terms of a relation between palindromic complexity and subword complexity
An assessment of the impact of possible CAP reform scenarios on Romanian agriculture
No full textUsing a simplified model, with key-variable the prices of two different possible scenarios of CAP reform after 2013 (moderate and radical), this paper present a comparison between the price effects of implementation of each reform scenario at 2015 horizon on Romanian agriculture. This short analysis shows that, under the presented hypotheses, the net welfare effect, due to the price changes, for the selected products, is positive in both reform scenarios, yet greater in the case of the radical reform. Integrated in the large context of Romanian development, it seems that the influence of CAP reform upon agriculture and rural areas will be most likely a gradual one: an interpenetration between the two scenarios is foreseeable, starting with the moderate reform that will dominate the period around 2013, the reform measures acquiring a more radical character afterwards.CAP reform, Romania, welfare effects, Agricultural and Food Policy,

Avaliação dos efeitos centrais do extrato aquoso (EA) de Stachytarpheta cayennensis Vahl
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências BiológicasNo presente estudo, investigamos as ações do EA de S. cayennensis no sistema nervoso central (SNC) de camundongos, procurando avaliar uma possível atividade que pudesse contribuir para as ações farmacológicas descritas na literatura. Camundongos Swiss fêmeas foram tratados com EA de S. cayennensis (0,25; 0,5 e 1 g/kg) ou água (controle) por via intragástrica e, após 3 h, foram submetidos a diferentes testes comportamentais: labirinto em cruz elevado, nado forçado, comportamento estereotipado, convulsões induzidas por pentilenotetrazol e eletrochoque transcorneal máximo, sono barbitúrico e etéreo, temperatura retal, movimentação e rota-rod. Nossos resultados mostraram que o tratamento oral agudo com o EA de S. cayennensis somente potenciou o sono barbitúrico, evidenciando a falta de atividade central do extrato em estudo. Investigou-se então a hipótese do EA interferir em vias metabolizadoras hepáticas do pentobarbital. O aumento dos níveis plasmáticos de pentobarbital após o tratamento com o EA indicou um efeito inibidor do sistema enzimático hepático responsável pela metabolização do pentobarbital, sem qualquer sinal de hepatotoxicidade. Assim, a potenciação do sono produzida pelo EA deveu-se simplesmente a um efeito farmacocinético e não a uma atividade no SN
On the number of episturmian palindromes
No full textEpisturmian words are a suitable generalization to arbitrary alphabets of Sturmian words. In this paper we are interested in the problem of enumerating the palindromes in all episturmian words over a -letter alphabet . We give a formula for the map giving for any the number of all palindromes of length in all episturmian words over . This formula extends to a similar result obtained
for by the second and third author in 2006. The map is expressed in terms
of the map counting for each the palindromic prefixes of all standard episturmian words
(epicentral words). For any , where is the totient Euler function.
The map plays an essential role also in the enumeration formula for the map counting for each the finite episturmian words over . Similarly to Euler's function, the behavior of is quite irregular.
The first values of and of the related maps , and for have been calculated and reported in the Appendix.
Some properties of are shown. In particular, broad upper and lower bounds for , as well as for and , are determined.
Finally, some conjectures concerning the map are formulated
A generalized palindromization map in free monoids
No full textThe palindromization map ψ in a free monoid A* was introduced in 1997 by the first author in the case of a binary alphabet A, and later extended by other authors to arbitrary alphabets. Acting on infinite words, ψ generates the class of standard episturmian words, including standard Arnoux-Rauzy words. In this paper, we generalize the palindromization map, starting with a given code X over A. The new map ψX maps X* to the set PAL of palindromes of A*. In this way, some properties of ψ are lost and some are saved in a weak form. When X has a finite deciphering delay, one can extend ψX to Xω, generating a class of infinite words much wider than standard episturmian words. For a finite and maximal code X over A, we give a suitable generalization of standard Arnoux-Rauzy words, called X-AR words. We prove that any X-AR word is a morphic image of a standard Arnoux-Rauzy word and we determine some suitable linear lower and upper bounds to its factor complexity. For any code X, we say that ψX is conservative when ψX( X*)⊆ X*. We study conservative maps ψX and conditions on X assuring that ψX is conservative. We also investigate the special case of morphic-conservative maps ψX, i.e., maps such that φ°ψ= ψX°φ for an injective morphism φ. Finally, we generalize ψX by replacing palindromic closure with θ-palindromic closure, where θ is any involutory antimorphism of A*. This yields an extension of the class of θ-standard words introduced by the authors in 2006
