This paper proposes a method to deduce the first four moments and the co-moments (with any other asset) of an option return. We consider the dynamics of an option-replicating portfolio of four basic assets: the underlying, two long-term options and a zero coupon bond. This approach allows us to capture the moments up to order four of the underlying and to linearize the option return. A numerical example illustrates some of the features and applications of this model. [less ▲]

In optics, chirality is typically associated with circularly polarized light. Here we present a novel way to detect the handedness of chiral materials with linearly polarized light. We performed Second Harmonic Generation (SHG) microscopy on G-shaped planar chiral nanostructures made of gold. The SHG response originates in distinctive hotspots, whose arrangement is dependent of the handedness. These results uncover new directions for studying chirality in artificial materials.

An erratum is presented to clarify both the direction of light polarization in our experiments and the unit cell geometry of the samples. Additionally, the spectral dependence of the second harmonic generation response in the G-shaped nanostructures made of gold is corrected. These changes do not affect our previous conclusions.

Lineweaver-Burk, Hanes, Eadie-Hofstee and Dixon plots can only be used when a true initial rate is measured. Despite the fact that this point has often been stressed, it is far too often ignored in favour of restricting the essay time to one where low amounts of substrate are used. When one or several irreversible and slow steps occur with an inactivator during the incubation of a ternary enzyme-substrate-inactivator mixture, the rate of the enzyme-catalyzed reaction progressively decreases. Even under these conditions, the present computer simulations investigations show that apparently linear Lineweaver-Burk, Hanes, Eadie-Hofstee and Dixon graphs can be obtained when the amount of product is mistakenly assumed to represent the true initial rate. Moreover, the observed pattern can change with time, going for instance from non-competitive to competitive. "Ki's" measured under these conditions also vary with time and bear little relationship to the true constants involved in the interaction. [less ▲]

Lingopti project is a First Europe project. It treats semi-continuous casting of copper-nickel alloys ingots. The research, performed in the University of Liège, consists in the optimisation of the mould and the whole casting process of the LBP S.A. company (Chênée – Liège) to obtain better cast products. In fact, cast products sometimes present long oscillation marks (λ ≈ 500mm) and some ingots have many internal cracks. The semi-continuous process consists in the vertical casting of 7m height ingots. The goal is also to test different chemical compositions of the material and to predict what happens on the casting process. [less ▲]

The following text deals with casting of copper-nickel alloys. They are high added values materials. The research contains two main parts. Laboratory tests (completed with bibliography) that provide thermal and mechanical properties of the ingot and the mould but also heat transfer coefficients between the ingot and its environment (mould, air and water). These parameters are required in the second part : development and validation of numerical modelization by the finite element method to optimise the industrial process. [less ▲]

This essay examines Gbenga Agbenugba’s Another Lonely Londoner (1991), a rarely discussed novel recounting the experiences of a young Nigerian man living in London. The narrative is written in an experimental style mixing English with Nigerian Pidgin, and including elements of Nigerian English, Black British English, Cockney, and Yoruba. By way of introduction, Agbenugba’s work is briefly discussed in relation to the novel that inspired it, Sam Selvon’s The Lonely Londoners (1956). An analysis is then undertaken of the interaction between English and Nigerian Pidgin in Another Lonely Londoner, both in dialogue and in narrative passages, with a view to assessing the impact of the combined use of these languages on possible literary interpretations of the novel. The other codes, varieties, and linguistic influences revealed in the book also receive systematic treatment, and it gradually appears that all these elements combine to produce a complex polyphonic work mirroring the main character’s multifarious identity.

If you have a look on the media in the German-speaking Community of Belgium (GC), you will find how prevalent the subject of language is in the minds of the German-speaking Belgians. East Belgian linguistic characteristics are frequently treated in the media (cf. e.g. the radio competition “Ostbelgien lernt Deutsch – der germanistische Adventskalender“) and just recently, a popular scientific dictionary of East Belgian everyday language has been published. This suggests that in the GC, there is a feeling that German as it is spoken in East Belgium differs from German spoken in the Federal Republic of Germany. This project asks the question of how East Belgian linguistic characteristics in everyday language are perceived and judged by the German-speaking Belgians, and to what extent they are part of their linguistic identity. Special attention is paid to the question of how far linguistic identity, language attitudes and language perception in the GC are influenced by the political and cultural situation of the region. The German-speaking Community is a partly independent political entity within the Belgian federal system. The eventful history of the region (3 changes in nationality within 25 years) and the minority situation have made it difficult for the inhabitants of the GC to find their own identity and a sense of “we-ness”. The inhabitants of the GC speak a language whose “mother country” is neighbouring Germany and they are closely linked to German culture through the media – nevertheless, they do not feel German. At the same time, within the state of Belgium, they are a linguistic minority, but they are also linked to Belgian culture through intensive contacts. Within Belgium, the German-speaking Belgians can use the German language to claim uniqueness (cf. the term “German-speaking Community”), but this does not work on the international level. But can dissociation from the German citizens happen on a linguistic level nevertheless, through regional variants and varieties? Since there are basically great similarities between the linguistic situation in the GC and in the bordering German areas (both on the level of the traditional dialects and regional linguistic features as well was in the vertical structure of variety use), while the extra-linguistic situations are very different, a comparative survey across the Belgian-German border is especially enlightening. The most important questions I want to raise are thus: How strong is the feeling that the regional everyday speech differs from that spoken on the other side of the national border? To which degree do these beliefs correspond to reality? What is in the eyes of the local population on both sides of the frontier typical of this variety? How do they evaluate it? And which functions do occurring regional features of German have for the identity of the people on both sides of the frontier? The methodology and first results have been presented on the poster.

The aim of this lecture was to investigate the relation between scribal variation and language change in pre-Demotic Egyptian, focusing more specifically on “The best case scenario in the worst cultural environment”, i.e. the text community of Deir el-Medineh during the 20th Dynasty. The talk was methodologically oriented and several case-studies (related to the diaphasic and diachronic dimensions of variation) were presented in order to illustrate some principles and to suggest new ways of investigation in the description of Ancient Egyptian variation. Additionally, the possibility of a scribal network analysis of the written material found in Deir el-Medineh has been discussed. [less ▲]
