Tight-minimal dichotomies in Banach spaces

We extend the methods used by V. Ferenczi and Ch. Rosendal to obtain the `third dichotomy' in the program of classification of Banach spaces up to subspaces, in order to prove that a Banach space E with an admissible system of blocks with admissible set A, contains an infinite dimensional subspace with a basis which is either A-tight or A-minimal. In this setting we obtain, in particular, dichotomies regarding subsequences of a basis, and as a corollary, we show that every normalized basic sequence has a subsequence which either satisfies a tightness property or is spreading. Other dichotomies between notions of minimality and tightness are demonstrated, and the Ferenczi-Godefroy interpretation of tightness in terms of Baire category is extended to this new context.Comment: 42 page

Meeting the Expectations of Your Heritage Culture: Links between Attachment Style, Intragroup Marginalisation, and Psychological Adjustment

This article has been made available through the Brunel Open Access Publishing Fund.This article has been made available through the Brunel Open Access Publishing Fund.Do insecurely-attached individuals perceive greater rejection from their heritage culture? Few studies have examined the antecedents and outcomes of this perceived rejection – termed intragroup marginalisation – in spite of its implications for the adjustment of cultural migrants to the mainstream culture. The present study investigated whether anxious and avoidant attachment orientations among cultural migrants were associated with greater intragroup marginalisation and, in turn, with lower subjective well-being and flourishing, and higher acculturative stress. Anxious attachment was associated with heightened intragroup marginalisation from friends and, in turn, with increased acculturative stress; anxious attachment was also associated with increased intragroup marginalisation from family. Avoidant attachment was linked with increased intragroup marginalisation from family and, in turn, with decreased subjective well-being

Narráció és retorika = Narrative and Rhetoric

A kutatás a narratológiai és a retorikai elemzések egymással való kapcsolatba hozásának lehetőségeit vizsgálta. Különös figyelmet fordítottunk az irodalomtörténeti elbeszélésre, amely egyrészt történetet mond, másrészt meggyőzni igyekszik, következésképpen narratív és retorikai formáltsága elvileg sem választható szét, valamint a fenségesre, amely az elbeszélhetetlen elbeszélése, és így a lehetetlen megvalósítására talál retorikai stratégiákat, a narratíva megszakításaként is értelmezhető. Prométheusz mítoszát választottuk ki annak vizsgálatára, milyen retorikával beszélhető el újra és újra az európai kultúra egyik alaptörténete. | The project focused on the potentials of connecting narratological and rhetorical analyses. A special emphasis was laid on the literary historical narration, which both tells a (hi)story and tries to persuade readers, and therefore its narrative and rhetorical formations cannot be theoretically separated; another important issue was the sublime, which can be described as the narration of what cannot be narrated, and therefore it seeks for rhetoric strategies to realize the impossible. The project has chosen the myth of Prometheus to analyze which rhetoric strategies make possible the repeated retelling of a basic story of the European culture

Local Complexity of Delone Sets and Crystallinity

This paper characterizes when a Delone set X is an ideal crystal in terms of restrictions on the number of its local patches of a given size or on the hetereogeneity of their distribution. Let N(T) count the number of translation-inequivalent patches of radius T in X and let M(T) be the minimum radius such that every closed ball of radius M(T) contains the center of a patch of every one of these kinds. We show that for each of these functions there is a `gap in the spectrum' of possible growth rates between being bounded and having linear growth, and that having linear growth is equivalent to X being an ideal crystal. Explicitly, for N(T), if R is the covering radius of X then either N(T) is bounded or N(T) >= T/2R for all T>0. The constant 1/2R in this bound is best possible in all dimensions. For M(T), either M(T) is bounded or M(T) >= T/3 for all T>0. Examples show that the constant 1/3 in this bound cannot be replaced by any number exceeding 1/2. We also show that every aperiodic Delone set X has M(T) >= c(n)T for all T>0, for a certain constant c(n) which depends on the dimension n of X and is greater than 1/3 when n > 1.Comment: 26 pages.

Na outra cena da representação: considerações ferenczianas sobre o trauma

O objetivo deste artigo é abordar as contribuições ferenczianas acerca do trauma para enaltecer a pluralidade do psiquismo, seja formado por traços psíquicos representados ou por marcas traumáticas que extrapolam o campo da representação. Por conseguinte, propõe-se que as vertentes estruturante e desestruturante do trauma sejam compreendidas não como predicados de diferentes tipos de trauma, mas como movimentos inerentes à constituição psíquica. Assim sendo, a clínica psicanalítica deve extrapolar um modelo estanque de psiquismo para contemplar as produções subjetivas que se dão na outra cena da representação, dentre elas a dimensão sensível da linguagem

Regulatory light chains in cardiac development and disease

Copyright © 2021 The Author(s). The role of regulatory light chains (RLCs) in cardiac muscle function has been elucidated progressively over the past decade. The RLCs are among the earliest expressed markers during car-diogenesis and persist through adulthood. Failing hearts have shown reduced RLC phosphoryla-tion levels and that restoring baseline levels of RLC phosphorylation is necessary for generating optimal force of muscle contraction. The signalling mechanisms triggering changes in RLC phos-phorylation levels during disease progression remain elusive. Uncovering this information may provide insights for better management of heart failure patients. Given the cardiac chamber-specific expression of RLC isoforms, ventricular RLCs have facilitated the identification of mature ventricular cardiomyocytes, opening up possibilities of regenerative medicine. This review consolidates the standing of RLCs in cardiac development and disease and highlights knowledge gaps and potential therapeutic advancements in targeting RLCs.Singapore Ministry of Education Academic Research Funds (MOE2016-T2-1-106 and 2018-T1001-030).; K.M. funded by Nanyang Technological University research scholarship

Canonical Representatives of Morphic Permutations

An infinite permutation can be defined as a linear ordering of the set of natural numbers. In particular, an infinite permutation can be constructed with an aperiodic infinite word over $\{0,\ldots,q-1\}$ as the lexicographic order of the shifts of the word. In this paper, we discuss the question if an infinite permutation defined this way admits a canonical representative, that is, can be defined by a sequence of numbers from [0, 1], such that the frequency of its elements in any interval is equal to the length of that interval. We show that a canonical representative exists if and only if the word is uniquely ergodic, and that is why we use the term ergodic permutations. We also discuss ways to construct the canonical representative of a permutation defined by a morphic word and generalize the construction of Makarov, 2009, for the Thue-Morse permutation to a wider class of infinite words.Comment: Springer.
