Antiparallel d-stable Traces and a Stronger Version of Ore Problem

In $2013$ a novel self-assembly strategy for polypeptide nanostructure design which could lead to significant developments in biotechnology was presented in [Design of a single-chain polypeptide tetrahedron assembled from coiled-coil segments, Nature Chem. Bio. 9 (2013) 362--366]. It was since observed that a polyhedron $P$ can be realized by interlocking pairs of polypeptide chains if its corresponding graph $G(P)$ admits a strong trace. It was since also demonstrated that a similar strategy can also be expanded to self-assembly of designed DNA [Design principles for rapid folding of knotted DNA nanostructures, Nature communications 7 (2016) 1--8.]. In this direction, in the present paper we characterize graphs which admit closed walk which traverses every edge exactly once in each direction and for every vertex $v$, there is no subset $N$ of its neighbors, with $1 \leq |N| \leq d$, such that every time the walk enters $v$ from $N$, it also exits to a vertex in $N$. This extends C. Thomassen's characterization [Bidirectional retracting-free double tracings and upper embeddability of graphs, J. Combin. Theory Ser. B 50 (1990) 198--207] for the case $d = 1$.Comment: 22 pages, 8 figure

Numerical interactions between compactons and kovatons of the Rosenau-Pikovsky K(cos) equation

A numerical study of the nonlinear wave solutions of the Rosenau-Pikovsky K(cos) equation is presented. This equation supports at least two kind of solitary waves with compact support: compactons of varying amplitude and speed, both bounded, and kovatons which have the maximum compacton amplitude, but arbitrary width. A new Pad\'e numerical method is used to simulate the propagation and, with small artificial viscosity added, the interaction between these kind of solitary waves. Several numerically induced phenomena that appear while propagating these compact travelling waves are discussed quantitatively, including self-similar forward and backward wavepackets. The collisions of compactons and kovatons show new phenomena such as the inversion of compactons and the generation of pairwise ripples decomposing into small compacton-anticompacton pairs

The Return of the Edwardians in Contemporary Fiction

My research stems from the hypothesis that a subgenre exists within the contemporary historical novel in English with a series of features that can be labelled as neoEdwardian and belong in a broader social and cultural phenomenon. Thus, trough the analysis of a series of recent novels set in the years prior to the First World War, this dissertation could contribute to the study of the relationship that we establish with the past, especially when History and fiction interact in novels. The main goals of this research are: 1. To delve into the state of the art of contemporary historical fiction in English. 2. To trace the state of the art of the neo-Edwardian novel, including a chronology of primary works and their evolution. 3. To analyse a series of primary works that could be considered neo-Edwardian and to obtain some common features. 4. To investigate critical concepts about our contemporary views on the past that can be related to this subgenre. 5. To contribute to the study of the neo-historical novel. In order to achieve this, a thorough examination of a selection of contemporary novels set in the Edwardian period is being carried out. The theoretical framework employed revolves around memory in contemporary fiction and the evolution of the historical novel in the 20th and the 21st centuries.Universidad de Málaga.

Remapping the European Cultural Memory: The Case of Julia Kristeva’s \u3cem\u3eMurder in Byzantium\u3c/em\u3e

This article considers Julia Kristeva’s novel Murder in Byzantium in the context of some of the most pressing ehtical and political dilemmas faced by Europe today, regarding the role of religion and the inclusion of religious references in the Constitution of the European Union. It traces Kristeva’s remapping of the European tradition, and places feminine creativity at the core of her analysis. I argue that this remapping that revalorizes feminine creativity and sensibility envisions the question of the eternal Europe as an illusion to be endlessly reinvented

Displaying Mr Selfridge

Whereas, in literature a stream of recent bio-fictions have focused their efforts on resurrecting great Edwardian authors, the first season of Mr Selfridge (2013), based on Lindy Woodhead’s biography Shopping, Seduction & Mr Selfridge (2007), features a capitalist hero and constitutes an intriguing object of study which connects the present context with the history of England and of costume drama itself. Consequently, this paper will analyse the series in terms of how it relates to and differs from other representations of Edwardian characters, in an attempt to explore what the impulse lying behind Mr Selfridge’s filmic return could be.Universidad de Málaga.

In what circumstances is investment in HR worthwhile?

INTRODUCTION By High Speed Rail (HSR) we normally mean rail technologies capable of speeds of the order of 300km ph on new dedicated track. Such systems offer journey times that are more competitive with other modes, and particularly air, than traditional train services, and very high capacity. But their capital cost is also high. The proposals of the European Commission for the Trans European Transport Network (TEN-T) envisage expenditure of 600b euros, of which 250b euros is for priority projects, and a large part of this expenditure is for high speed rail. Thus it is extremely important to have a robust appraisal methodology for these huge investments. It is not clear that this has happened in the case of the Trans European Networks. Individual projects are suggested by, and appraised by, member state governments, even though they are applying to the European Commission for assistance with funding. Research for the European Commission has appraised the TEN-T network as a whole, but has not appraised the individual elements of the programme to ensure that they are all worthwhile (TML, 2005). The aim of this paper is to consider the methodology for the appraisal of high speed rail proposals, and to produce some indication of the circumstances in which such proposals might be worthwhile. In the next section we present an overview of the principal costs and benefits which need to be taken into account in an HSR appraisal. Then we illustrate the process for two particular contrasting examples – the study of HSR proposals in Great Britain, and an ex post evaluation of the Madrid-Seville line in Spain. In section four of the paper we formulate a model to incorporate the principal parameters influencing the outcome of an appraisal and in section five we use this model to draw conclusions on the circumstances in which high speed rail may be justified

Fixed point theorems for α\alpha--contractive mappings of Meir--Keeler type and applications

In this paper, we introduce the notion of $\alpha$--contractive mapping of Meir--Keeler type in complete metric spaces and prove new theorems which assure the existence, uniqueness and iterative approximation of the fixed point for this type of contraction. The presented theorems extend, generalize and improve several existing results in literature. To validate our results, we establish the existence and uniqueness of solution to a class of third order two point boundary value problems

EVALUATION OF NATIONAL BANK OF ROMANIA MONETARY POLICY CREDIBILITY

In this paper, using the models from the economic literature, the authors study the credibility level of National Bank of Romania (NRB) during the time span Mars 2007 - Mars 2008. We will use three types of credibility indexes - two from the economic literature and one proposed by the authors. Also, we will emphasize the impact of unpredictable shocks - the natural calamities (drought) which affected the aggregate supply in the summer of 2007 and the depreciation of RON against the euro - on the NBR credibility.In this paper, using the models from the economic literature, the authors study the credibility level of National Bank of Romania (NRB) during the time span Mars 2007 - Mars 2008.
